Use method of sewage treatment machine

Abstract

The invention discloses a use method of a sewage treatment machine. The sewage treatment machine performs solid-liquid separation based filtering treatment on stone sewage by adopting a ceramic filtering plate provided with micro-filtering holes as a filtering medium. The use method of the sewage treatment machine comprises steps of standing and conveying of the stone sewage, filtering treatment of the stone sewage, joint cleaning and shutdown cleaning, wherein the filtering treatment of the stone sewage further comprises steps of slurry suction, drying, discharging and backwashing. By adopting the method for filtering the sewage produced during stone processing, the filtering effect is good, a filtrate is clear and transparent, and drying property of a filter cake is good. Besides, compared with the conventional stone sewage treatment method, the method has the advantages that energy consumption can be reduced by about 80% or more, the service life of the ceramic filtering plate and the service life of each ultrasonic resonator box can be prolonged effectively, stable operation is facilitated, service life of the machine is prolonged greatly, production cost of an enterprise is reduced greatly, and production efficiency of the enterprise is increased.

Description

technical field [0001] The invention relates to a method for using a sewage treatment machine, in particular to a method for using a sewage treatment machine capable of filtering sewage generated during stone processing. Background technique [0002] At present, in the process of stone processing and production, it is often necessary to consume a large amount of water resources, and at the same time, a large amount of stone sewage will be generated. Stone sewage contains stone powder and sludge. After being directly discharged into rivers, ponds or reservoirs, it will cause serious pollution to water bodies. . In order to make the stone processing and production process more environmentally friendly, it is often necessary to filter the stone sewage to separate the stone powder and sludge from the stone sewage, and the formed filter cake and filtrate can be recycled and reused separately, which not only protects the environment but also saves energy. Substantial water and se...

AI Technical Summary

Problems solved by technology

However, the filtration effect of the sewage treatment machines currently on the market is not ideal, the filtrate separated by filtration is not clear and transparent, and the drying performance of the filter cake is also poor, which is not conducive to the recovery and reuse of the filtrate and filter cake, especially when the equipment is running for a period of time. After a period of time, it is prone to problems such as unstable operation of the equipment and poor filtering effect; in addition, the existing sewage treatment machine consumes a lot of energy, which is not conducive to saving the cost of filtering production
