Problems solved by technology

However, the existing treatment system has the defects of large area of ​​sewage treatment, complicated operation, poor treatment effect and low treatment efficiency. In addition, water pumps are used to transport sewage between various processes. Sand, etc. will clog the water pump, which will undoubtedly increase the maintenance cost

Embodiment Construction

[0016] The present invention will be further described below in conjunction with accompanying drawing, protection scope of the present invention is not limited to the following:

[0017] like figure 1 As shown, the three-dimensional biological turntable A-RBC sewage treatment process includes the following steps:

[0018] S1. Discharging the sewage into the grid well 1, the grid 2 in the grid well 1 intercepts a large amount of suspended matter and floating matter of larger particles, and the sewage passes through the grid 2 and enters the grid well 1;

[0019] S2. The sewage treated in step S1 flows into the regulating tank 3 by gravity from the grid well 1, and then lifts into the denitrification tank 4 to degrade the oil, organic matter and anionic surfactant in the sewage, and at the same time, denitrify The denitrification bacteria in the denitrification tank 4 reduce nitrate and release molecular nitrogen or nitrous oxide, realizing the removal of nitrate in sewage;

Abstract

The invention discloses three-dimensional biological rotating disk A-RBC sewage treating process. The sewage treating process comprises the following steps: S1, sewage is drained into a grating well, a lot of larger-particle suspended articles and floating articles are intercepted by a grating in the grating well, and the sewage penetrates through the grating to enter the grating well; S3, an organism in the sewage is degraded, and mixed liquid flows back to an adjusting tank; S5, suspended matters in the sewage is further removed, and phosphorus in the sewage is removed at the same time; S6, nitrogen and phosphorus in the sewage are absorbed by vegetation in an artificial rapid infiltration tank, then the sewage flows automatically to enter a pipe type ultraviolet sterilizer, germs and the like in the sewage can be killed by ultraviolet rays emitted from the pipe type ultraviolet sterilizer to a pipeline, and treated clean water meeting a draining standard is drained into a ditch through the pipe type ultraviolet sterilizer. The three-dimensional biological rotating disk A-RBC sewage treating process has the advantages of effectively removing the organism, nitrate, the phosphorus and the suspended matters in the sewage, being advanced and reliable and being low in investment, convenient to operate and manage, reasonable in layout and good in treating effect.

Description

technical field [0001] The invention relates to the technical field of domestic sewage treatment, in particular to a three-dimensional biological turntable A-RBC sewage treatment process. Background technique [0002] Domestic sewage is mainly composed of feces and washing sewage, which contains a large amount of organic matter, nitrate, sludge or floating matter, etc. Domestic sewage is mainly organic pollutants, and its composition is complex, mainly including oil, floating matter, and anionic surface activity If they are directly discharged into the water body without treatment, organic matter, surfactants, aromatics, phosphorus and other pollutants in the sewage will not only produce foam, but also the phosphorus and surfactants in the wastewater will It will absorb oxygen in the water body, destroy organic organisms, cause the water body to turn black and smelly, cause serious environmental pollution, and severely restrict investment development. At the same time, bact...
