Sludge magnetic concentration dewatering system

Abstract

The invention relates to a sludge magnetic concentration dewatering system which comprises an automatic agent dissolving and adding device, an agent adding metering pump and a magnetic seed agent dissolving box, and further comprises a magnetic seed feeding device, a sludge lifting pump, a condensation precipitation pool, a sludge screw pump, a magnetic drum, a stacked-screw sludge dewatering machine, a sludge spiral conveyor and a sludge collection bucket which are connected sequentially. The condensation precipitation pool, the automatic agent dissolving and adding device, the agent adding metering device and the stacked-screw sludge dewatering machine are connected sequentially, and the condensation precipitation pool, the magnetic seed feeding device, the magnetic seed agent dissolving box and the magnetic drum are connected sequentially. The sludge magnetic concentration dewatering system is high in sludge condensation speed, short in condensation time, good in condensation effect and high in automation level; intelligent control is adopted, so that the system can be remotely monitored and operated on wireless terminal equipment; the system is provided with an automatic alarming device, can immediately send a message reminding that handling is needed when a failure occurs or PAM powder needs to be supplemented and give an on-site alarm to remind on-site working personnel to handle and is safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment, and in particular relates to a sludge magnetic concentration and dehydration system. Background technique [0002] The sludge treatment system of the sewage treatment plant is equipped with a sludge thickening tank. The purpose is to use gravity to further increase the sludge concentration, reduce sludge production, reduce subsequent sludge dehydration pressure, and comprehensively reduce sludge treatment operating costs and equipment investment costs. . However, the conventional sludge thickening tank occupies a large area and has a long sedimentation period; the sludge deposited at the bottom of the tank is fermented anaerobically for a long time, which will easily release toxic and harmful substances in the sludge, and the sludge will stink, causing secondary pollution; The final sludge is not easy to dehydrate, which is not conducive to the normal operation of the sewage plant.
