Background

Activated sludge is a generic term for microbial populations and the organic and inorganic substances to which they attach. The activated sludge process is an aerobic treatment method for treating organic sewage by utilizing suspended and grown microbial flocs, and when the waste activated sludge is treated, dehydration and filtration treatment are required due to the fact that the waste activated sludge contains a certain amount of water and impurities.

When the activated sludge dewatering and filtering device in the prior art works, activated sludge is guided into the device through the guide pipe, so that the activated sludge is concentrated on the surface of a filter screen arranged in the device, the activated sludge is filtered and dewatered through a precipitation method or an extrusion method, and finally the activated sludge is guided out from the device. The principle of the precipitation method is that the activated sludge is semisolid, has poor fluidity and cannot naturally pass through a filter screen, but has long dehydration time and poor effect, so the conventional extrusion method is used for sludge dehydration treatment. When the filter screen is used for filtering by the extrusion method, when the extrusion structure extrudes the activated sludge, the activated sludge is separated from the activated sludge and descends through the filter screen, but part of the activated sludge can descend through the filter screen under the action of the extrusion structure, the effect of the separation of the activated sludge and the water can not be thoroughly achieved, and when the extrusion structure extrudes the activated sludge, a filter screen at the bottom is usually stressed, and the filter screen is damaged under the long-time extrusion, so that the activated sludge dehydration filter device is provided.
