Water purification box of sewage treatment system

Abstract

The invention relates to a water purification box of a sewage treatment system. The water purification box comprises a box body; a rotary support plate is arranged at the bottom of the box body; one end of the rotary support plate is articulated with the bottom of the box body, and the other end of the rotary support plate is connected with a fixing mechanism on the inner wall of the box body; therotary support plate is provided with a plurality of support seats which are arranged at equal intervals; each support seat is provided with a bayonet; the bayonets of the plurality of support seatsare respectively and internally provided with filtering plates in a way of clamp connection; filter holes are formed in the filtering plates; a cavity arranged between the every two adjacent filteringplates is a filtering cavity. The apertures of the filter holes formed in a first filtering plate, a second filtering plate, a third filtering plate and a fourth filtering plate are sequentially decreased; water flowing out from a water outlet is subjected to four-stage filtration, and multistage preliminary filtration can be completed without needing flow power provided by a water pump, so thatthe filtering effect is good.

Description

technical field [0001] The invention relates to the field of sewage purification, in particular to a clean water tank of a sewage treatment system. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and more and more enters the daily life of ordinary people. Sewage treatment is generally carried out first through water supply tanks After preliminary filtration, it enters the water purification system and is filtered by the filter element. Now the water supply tank of the water purification system generally uses a filter for simple filtration, but the flow power of the water in the filtration process needs to be provided by a power pump. The overall cost is high,...

Sewage treatment is generally carried out first through water supply tanks After preliminary filtration, it enters the water purification system and is filtered by the filter element. Now the water supply tank of the water purification system generally uses a filter for simple filtration, but the flow power of the water in the filtration process needs to be provided by a power pump. The overall cost is high, and the effect of preliminary purification is not good. great
