Abstract

The invention discloses a belt filter press for sludge dehydration. The belt filter press comprises an upper filter belt, a lower filter belt, a frame, a pressing area, a rinsing device, a rectification and protection device, a synchronous tensioning device, a transmission and unloading device, an electric connection box, a pneumatic control system, and a uniform material distributing device (6), wherein the pressing area comprises a pre-pressing arrangement area (8), a low-pressure pressing area (3) and a high-pressure pressing area (2); the lower filter belt is connected with the upper filter belt in the pre-pressing arrangement area (8) after passing through the uniform material distributing device (6), and then the upper and lower filter belts pass through the low-pressure pressing area (3) and the high-pressure pressing area (2), and are separated from the transmission and unloading device. The belt filter press is novel high-pressure belt press dehydration equipment for deep dehydration of sludge of which the moisture content is about 80 percent, is compact in structure, reliable and durable, and can be effectively butted with the conventional equipment of a belt (concentration) filter press, a centrifugal machine and the like in a sewage treatment plant.

Description

technical field [0001] The invention relates to a novel sludge dewatering belt press filter which can be used for deep sludge dehydration treatment to lower the moisture content of the sludge. Background technique [0002] Many sewage treatment plants in China produce a large amount of sludge every day. The main dehydration equipment currently used are belt (concentrated) filter presses, centrifuges, box filter presses, etc. The moisture content of the sludge after traditional dehydration treatment is generally about 80%, and the sludge with this moisture content must be followed up to meet the environmental protection requirements. [0003] At present, the follow-up treatment of sludge with a moisture content of about 80% usually adopts methods such as landfill and concentrated deep dehydration. [0004] Sludge landfill without harmless treatment may cause secondary pollution to the environment and groundwater, so this method is not a harmless and sustainable method. [0...
