Large integrated sewage treatment device and sewage treatment process

Abstract

The invention discloses a large integrated sewage treatment device and a sewage treatment process. The device comprises an integral working frame, one side of the inner wall of the integral working frame is fixedly connected with a positioning block, the right side of the positioning block is fixedly connected with a primary screening box, the two sides of the top of the preliminary screening boxcommunicate with inlet pipes, the bottom of the preliminary screening box communicates with a discharging pipe, the bottom end of the discharging pipe communicates with a sewage isolation treatment box, and a glass observation window is arranged on the surface of the sewage isolation treatment box. The invention relates to the technical field of sewage treatment. According to the large integratedsewage treatment device and the sewage treatment process, the device can be used for treating sewage, and then classifies the sewage in time, so uneven treatment caused by centralized treatment is avoided; and a worker can observe the sewage treatment condition in the sewage isolation treatment box through the glass observation window, so the operation of adding reaction liquid into the sewage isolation treatment box in time is facilitated.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a large-scale integrated sewage treatment device and a sewage treatment process. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of being discharged into a certain water body or reused. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc. According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage, while domestic sewage It is the sewage generated in daily life, which refers to the complex mixture of various forms of inorganic and organic matter, including floating and suspended large and small solid pa...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a large-scale integrated sewage treatment device and sewage treatment process, which solves the problem that traditional large-scale sewage treatment devices often collect sewage into one place and then conduct centralized treatment of sewage, but in some In areas with a lot of domestic sewage, if all the sewage after the initial treatment is centrally treated, the decomposed treatment liquid cannot flow uniformly to all parts of the sewage due to the large amount of internal solid matter, and the uneven treatment of sewage in a concentrated manner will seriously affect the sewage treatment. problem of effect
