Sand washing sludge dewatering equipment mainly refers to solid-liquid separation equipment, including: centrifuge, belt filter press, plate and frame filter press, sludge drying integrated machine, etc. Sand washing sludge dewatering equipment has a wide range of applicability, such as: soil sludge treatment, oil field drilling mud treatment, mining sludge wastewater treatment, sand washing wastewater treatment in sand making yard, piling mud treatment, river dredging treatment, mud wall solidification, large-diameter pile foundation, pipe jacking construction, seepage prevention wall engineering, trenchless engineering and other fields.

Sand washing sludge dewatering equipment is mainly for the separation of some fine gravel, sludge and water. The separated water can be recycled, and the sludge can be fully utilized for backfilling, brick burning, paving, etc., in order to meet the requirements of environmental protection and energy saving.

Due to the complex and diverse mining processes in sand factories, the turbid water quality will reduce productivity and increase costs. The function of the sand washing sludge dewatering equipment is to reduce the amount of sludge after the sediment is separated, and treat the sewage sludge to a zero discharge state as much as possible.

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.
