Screw press sludge dewatering machine working process and use object

- Jul 13, 2018 -

The screw press sludge dewatering machine achieves the purpose of sludge dewatering by screw pressing.

 

Sludge is an inevitable product in sewage treatment and needs to be treated. Otherwise, direct discharge will pollute water quality and air, posing a serious threat to human activities and the ecological environment. Therefore, sludge treatment equipment is used to treat the sludge to avoid these problems.

 

The sludge can be divided into sludge dewatering and sludge drying in terms of treatment, and the equipment used is also different. Therefore, the screw press sludge dewatering machine is a machine and is used for sludge dewatering.

 

Working process of screw press sludge dewatering machine

The sludge is first concentrated, and after gravity concentration, it continues to advance along the direction of rotation of the screw shaft and is dehydrated under the action of extrusion. The dehydrated mud cake is discharged from the gap formed by the back pressure plate and the spiral body, and the sludge treatment amount and the moisture content of the mud cake can be adjusted through this gap.

 

The screw press sludge dewatering machine is used for industrial wastewater coagulation and sedimentation sludge, industrial wastewater excess activated sludge, urban water treatment surplus sludge, community sewage treatment sludge, water purification field, drug agglomeration sludge and water and fertilizer. The excess sludge is treated, and these are common types of sludge.
