Farm sludge dewatering equipment

In the sludge dewatering of farms, sludge dewatering equipment is the core and important equipment. The principle of sludge dewatering equipment in farms is the same as that of sludge dewatering equipment in other industries. There are many sludge dewatering equipment in farms. At present, domestic sludge treatment equipment includes centrifuges, plate and frame filter presses, chamber filter presses, diaphragm filter presses, and high-pressure sludge dryers. Different sludge treatment equipment the moisture content after dehydration is different.

The characteristics of farm pollution are high-concentration organic sewage sludge, high content of suspended solids and ammonia nitrogen, and high content of organic matter and microorganisms. The sewage sludge of the breeding site has the characteristics of three highs. The organic matter concentration COD is as high as 3000-12000mg/1, the ammonia nitrogen content is as high as 800-2200mg/1, the suspended matter is dozens of times more than SS, the color is deep, and it contains a lot of bacteria, organic phosphorus, Heavy metals, residual chemicals and other hazardous substances.

It has been proved by experiments that the effect of using the horizontal screw decanting centrifuge in the sludge dewatering process of the farm is better than that of other sludge dewatering equipment. The centrifuge adopts the principle of centrifugation. After being treated by the centrifuge, the water content of the sludge cake is low, the equipment covers a small area, and the capital construction cost is low, the device has the advantages of compact structure and so on.

The key to the production of aviation kerosene storage tanks

How to improve the reliability of aviation kerosene storage tanks? Aviation kerosene storage tanks are important fuel supply equipment for aviation oil companies. The importance of the manufacturing and production of aviation kerosene storage tanks directly determines the reliability of the transportation of aviation kerosene and the high-end quality of aviation kerosene.

The reliability of the use of aviation kerosene storage tanks requires strict control over the entire process of drawing design and manufacturing of aviation kerosene storage tanks. In view of the difficulties in the production and production of kerosene tanks, it is necessary to optimize the treatment plan and the specific operations of on-site production.

To improve the reliability of aviation kerosene storage tanks, attention should be paid to the following three difficult issues:

1) Difficulties in the production of the conical bottom of aviation kerosene storage tanks: There are certain difficulties in the production of the conical bottom of aviation kerosene storage tanks. The design and production of the slope of the tank bottom is a difficult point. To achieve a satisfactory degree of coordination, detailed analysis needs to be done in advance, the designed slope must be adapted to meet the specific use standards, and the bottom of the kerosene storage tank must have good integrity and the bottom plate can be coordinated with the tank body. Unite. The welding treatment of the conical bottom of the aviation kerosene storage tank is also very important. The number of welds should be reduced to a minimum, and the problem of welding deformation should be controlled.

2) Difficulties in installing the upper and lower end walls of aviation kerosene storage tanks: The difficulty in installing the upper and lower end walls of aviation kerosene storage tanks lies in the corresponding stress control, which requires strict control from the error aspect to avoid tank deformation caused by corresponding stress concentration. . The verticality, perimeter, and levelness of the upper and lower end wall panels of aviation kerosene storage tanks also need to be strictly controlled and corrected to ensure better forming integrity of the kerosene storage tank.

3) Difficulties in welding requirements for aviation kerosene storage tanks: In the manufacturing process of aviation kerosene storage tanks, the welding requirements for kerosene storage tanks are very high. The welding operation of kerosene storage tanks is actually closely related and mutually influencing with the shape requirements of aviation kerosene storage tanks. During the welding process, it is necessary to control weld defects caused by stress concentration. For the problem of welding seam defects, it is necessary to operate from the main aspect of welding scientific and reasonable design.

The above has explained the key points of the production and production of aviation kerosene tanks through three difficult aspects. To provide high-quality aviation kerosene receiving and dispatching operations, we must first handle the reasonable layout during the design stage of the aviation kerosene storage tank, and rationally arrange the steel plates and welds. At the location point, during the production process, the operation must be strictly abided by the regulations. After such a serious and strict production process, the reliability of the aviation kerosene storage tank can be improved.

Five schemes for remediation of oilfield soil pollution

The sources of oilfield soil pollution are mainly from the invasion of drilling mud during oil and gas exploration, extraction, transportation and storage. If the contaminated drilling mud cannot be disposed of in a timely, reasonable and effective manner, serious pollution of the soil around the oil field will occur. As the main source of pollution, drilling mud contains pollutants such as petroleum, heavy metals, organic chemicals, chloride ions and other pollutants that enter the soil without treatment, which will not only cause great harm to the soil, but also to the environment. The content of trace harmful elements in the soil exceeds the background value, and the content is too high due to excessive deposition, so it is called “soil heavy gold pollution”. Five schemes for remediation of oilfield soil pollution:

1) Oil sludge thermal desorption method oilfield soil pollution remediation plan:

The sludge thermal desorption method to remediate oilfield soil pollution is based on an integrated solution of solid-liquid separation. Through sorting equipment, the stones, weeds, tree roots and other sundries in the contaminated soil are separated; the proportions of oil and water are different. Physical properties: water, oil, and mud sand are fully stratified through water temperature and chemical stirring. The oil floats on the top layer according to the specific gravity. The water layer is in the middle, and the mud sand settles at the bottom layer. Finally, it passes through three-phase separation equipment or oil-water separation equipment. And mud-water separation equipment to achieve the purpose of three-phase separation of water, oil and mud.

2) Bio-method oilfield soil pollution remediation plan:

Bio-method oilfield soil pollution remediation program: Bioremediation is a method that uses biological growth and metabolism to degrade and transform organic matter. It has the characteristics of safety, reliability, and low repair costs. This soil pollution remediation plan includes: key processes, remediation preparations, supporting equipment and other core technologies.

3) Physical method of oilfield soil pollution remediation plan:

The physical method of oilfield soil pollution remediation program refers to pollution control technologies such as the soil method, incineration method, physical separation method, solution leaching method, solidification stabilization method, thermal desorption method and electrodynamic method based on physical methods.

4) United Technologies Oilfield Soil Pollution Remediation Plan:

The composition characteristics of oil and secondary metabolism determine the difficulty and complexity of oilfield soil pollution remediation. Therefore, a single technology cannot solve the pollution problem well, and it is necessary to consider the combined use of various treatment technologies.

5) Remediation plan for soil pollution of oilfield by leaching method:

The leaching method for remediation of oilfield soil pollution is an in-situ remediation method, which is very similar and close to the technical principles of “water flooding” and “polymer flooding”. The water from the injection well flows into the soil contaminated area of ​​the oilfield, so that the oil contaminants in the oilfield soil are flushed into the area that can be pumped out by the groundwater well under the accumulation and driving of the water. The extracted petroleum-contaminated groundwater and flushing water are treated by surface facilities, and the rinsing water is recycled and reused. After the treated wastewater meets environmental protection requirements, it is discharged. When choosing an oilfield soil pollution remediation plan, different soil pollution remediation plans should also be selected for the oilfield soil contaminated by light oil and heavy oil.

Construction Mud Treatment-mud dehydration and drying equipment

Improper treatment of construction mud will pollute the environment, cause a large amount of soil erosion, block up rivers, affect water quality, and destroy municipal facilities. Early Construction Mud Treatment methods included landfilling, natural drying, etc. These more primitive methods have lower costs, but they cannot meet the increasing Construction Mud Treatment needs.

Therefore, the mud dehydration and drying treatment introduced in recent years has the following contents:

(1) Vacuum suction filtration method: the effect is poor, because the mud settles in the lower layer. When the vacuum is applied, the mud layer becomes denser and the water is difficult to suck out.

(2) Filter press method: The effect is good, but it is difficult to use on the construction site.

(3) The centrifugal dehydration and drying method is better than the above two methods. The centrifugal closed automatic and continuous operation does not require flocculation equipment. It is suitable for on-site construction environment and can fundamentally replace the current original and backward processing methods and improve processing efficiency. Reduce processing costs, protect the urban environment, and achieve civilized construction on site.

Drilling waste treatment status and technology

In the process of oil exploration and production, a large amount of waste will be left on the well site. In view of these harmful substances, how to adopt corresponding drilling waste treatment technology to minimize the harm caused by waste drilling fluid to the environment is a very important task for oil and gas field enterprises.

drilling waste treatment

For a long time, most of the domestic oilfield drilling waste treatment is to directly solidify the waste liquid in the waste storage pool after the completion of the drilling and completion work. Due to the high water content in the total waste to be processed, this method consumes a lot of chemicals, has a high cost, and has an unsatisfactory effect, and it cannot completely eliminate the hidden danger of pollution.

With the requirements of local governments for environmental protection, the current domestic onshore oilfields are gradually paying attention to the harmless treatment of waste drilling fluid. Therefore, the treatment technology route with solid-liquid separation technology as the core has begun to be used in drilling waste treatment. This technology has changed from simple and rough direct solidification in the past to a process technology route combining chemical method, solid-liquid separation method and solidification method.

Dredging Slurry Separation Solution

River dredging process system is generally adopts a cutter suction dredger to absorb the muddy water mixture at the bottom of river, and then transport it along the pipeline to a sludge drying treatment field. After machine sorts the garbage mixed in mud, the mud is passed into the concentration tank in the field, and the mud water separation is carried out through the mud treatment system. Finally, water reaches the standard discharge, and the wet sludge is sent to sludge dewatering equipment to dehydrate and becomes solidified mud cake for reusing.

Dredging Slurry Separation Solution mainly used for the separation of sludge from rivers. KOSUN Dredging Slurry Separation Solution is consist of shale shaker, desander, desilter or decanter centrifuge for 3 to 6 stage separation depending on the needs.

KOSUN Dredging Slurry Separation Solution is consisting of 3 parts. The first one is the dredging boat and first stage separation pool for large size of the trash. The dredging boat is always moving on the surface of the lake or river, and the suction unit would go down deep to the bottom of the lake or river and then suck sludge then transfer to the ground by a hose which is always float on the water surface. On the ground, there will be a pool which is divided into several parts by different mesh size of wire screen. The sludge flow coming out from the hose will get into the pool; the large size of the trash in the sludge would be blocked by these several wire screens, while the slurry will flow away for next process.

The second part of the Dredging Slurry Separation Solution is the recycling system which is including several equipment that is used especially for the solids and liquid separation. The slurry will be fed into a scalping shaker, here the solids which is large than 1/8 inch would be separated out, and the slurry would then be pump transferred to the desander for much fine solids removing. After treated by the desander, almost all the solids with size of 50 microns would be removed out.

The third part of the Dredging Slurry Separation Solution is the ultra-fine solids removing equipment. Some contractors like to use the filter press as the final solids removing units, the solids separated are really dry and shaped like cake. While another option is to use the decanter centrifuge that could be used to remove the ultra-fine solids with size down to 2 microns. After treated by the filter press or the centrifuge, the water is already clean that could be flow back to the lake or river.
