Problems solved by technology

[0003] The bottom settlement of the currently used sewage sedimentation tank is fixed, and it is not easy to clean up the sediment after sedimentation. Especially when the sedimentation tank is large, it is more troublesome to take care of, and there are cases where the sedimentation treatment is not clean. If the treatment is not clean and long-term use will cause the bottom to agglomerate, it will be more difficult to clean up. Therefore, how to quickly and clean the bottom sediment is a problem that we need to consider

Embodiment 1

[0045] see Figure 1-8, a settling tank applied to sewage treatment, comprising a tank body 1, a positioning platform 2, a plurality of first movable settling platforms 3 and a second movable settling platform 4, and a sewage outlet 1-1 is dug on the side wall of the tank body 1 , and the lower edge of the inner wall of the sewage outlet 1-1 is on the same level as the inner bottom wall of the pool body 1, the positioning platform 2 is fixedly connected to the inner wall of the pool body 1 close to the inner bottom surface of the pool body 1, and the upper end of the positioning platform 2 faces The bottom of the pool body 1 is inclined; the second movable settling platform 4 is located at the lower side of the positioning platform 2, and a plurality of first movable settling platforms 3 are located between the positioning platform 2 and the second movable settling platform 4, and the plurality of first movable settling platforms 4 are positioned between the positioning platfor...

Abstract

The invention discloses a sedimentation tank applied to sewage treatment, belongs to the field of sewage treatment, and particularly relates to a sedimentation tank applied to sewage treatment, whichcomprises a tank body, a positioning table, a plurality of first movable sedimentation tables and a plurality of second movable sedimentation tables. The sedimentation tables are movably arranged, andaccumulated objects on the sedimentation tables are scraped off through the positioning table. Then a baffle is used for blocking, after the baffle is laid flat, sediment is collected and dischargedtogether, the sewage disposal efficiency is higher, meanwhile, the baffle is used, the baffle makes contact with the bottom wall of the pond while the baffle is laid flat, accumulated objects discharged from the baffle are limited between the baffle and the side wall of the pond and then discharged from a sewage discharging opening, the area is reduced, and the sweeping difficulty is lowered, besides, as the distance between the scraper close to the positioning table and the bottom wall of the pool is greater than that between the scraper far away from the positioning table and the bottom wallof the pool, the thicker part on the bottom wall of the pool can be scraped by the scraper close to the positioning table, and then the other scraper is used for secondary scraping, so that the scraper is not easy to damage due to excessive blockage of primary scraping.

Description

technical field [0001] The invention relates to the field of sewage treatment, more specifically, to a sedimentation tank applied to sewage treatment. Background technique [0002] Sedimentation tank is a structure that uses sedimentation to remove suspended solids in water and is an equipment for purifying water quality. Use the natural precipitation of water or the effect of coagulation and sedimentation to remove suspended solids in water. The sedimentation tank is divided into horizontal sedimentation tank and vertical sedimentation tank according to the direction of water flow. The sedimentation effect depends on the flow rate of the water in the sedimentation tank and the residence time of the water in the tank. In order to improve the sedimentation effect and reduce the land area, honeycomb inclined tube counterflow sedimentation tanks, accelerated clarifiers, pulse clarifiers, etc. are often used. Sedimentation tanks are widely used in wastewater treatment. Consi...
