Solid-liquid separation device for heavy metal sewage treatment

Abstract

The invention discloses a solid-liquid separation device for heavy metal sewage treatment. The solid-liquid separation device comprises a supporting mechanism, a filtering mechanism, a material suction mechanism, a washing mechanism and a water receiving mechanism, the supporting mechanism comprises a shell and supporting legs; the shell comprises a first half shell and a second half shell, and the first half shell and the second half shell are fixedly connected through bolts; the supporting legs are fixedly connected to the lower side of the shell; the filtering mechanism is arranged in the supporting mechanism; a feeding part of the material suction mechanism extends into the filtering mechanism; the brushing mechanism is arranged on the outer side of the filtering mechanism, and a water spraying part of the brushing mechanism faces the filtering mechanism; the water receiving mechanism is arranged in the supporting mechanism and is arranged on the lower side of the filtering mechanism, and the water outlet end of the water receiving mechanism downwards extends out of the supporting mechanism. According to the scheme, the second filter plate can be conveniently replaced, sludge on the second filter plate can be automatically removed, the blocking degree of the second filter plate is reduced, the first filter plate can be backwashed, and the maintenance frequency of the first filter plate is reduced.

Description

technical field [0001] The present application relates to the technical field of sewage treatment, in particular, to a solid-liquid separation device for heavy metal sewage treatment. Background technique [0002] Industrial wastewater refers to the wastewater generated in the industrial production process. Industrial wastewater often contains a large amount of heavy metal ions. Heavy metal ions will pollute the environment and are difficult to degrade under natural conditions. With the rapid development of modern industry, the production of industrial sewage containing heavy metal ions is increasing. If the heavy metal ions in industrial sewage are not removed and the sewage is directly discharged, it will not only cause great damage to the environment, but also It is also possible that the enrichment of the food chain will eventually cause great harm to the human body. [0003] When treating heavy metal sewage, chemicals are usually added to the heavy metal sewage to gene...
