Technical Field

The invention relates to the technical field of sewage treatment instruments, in particular to a vertical cylinder extrusion type filter press.

Background

A large amount of water-containing sludge is generated in the sewage treatment process, and the domestic dehydration method at the first stage mainly adopts a filter pressing-burning method to dehydrate and dry the sludge and then bury the sludge. However, the above method is in a semi-open state in the sludge dewatering process, and a large amount of odor is generated, so that the semi-manual operation environment is severe, and the surrounding environment is affected. And the dehydration process can only reduce the water content of the sludge from 98% to about 60%, so that the water content of the sludge can be reduced to the standard for landfill only by using a large amount of energy consumption for evaporating water during subsequent drying, and a large amount of energy is wasted. Therefore, a new dehydration device is needed to carry out pollution-free and high-efficiency dehydration.
