Embodiment Construction

[0024] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0025] see figure 1, a new type of wastewater treatment process using pure microorganisms to treat high-concentration industrial wastewater, including a grid 1, a grit chamber 2, a flow regulating tank 3, a primary biochemical pool 4, a primary sedimentation tank 41, a secondary biochemical pool 5, Secondary sedimentation tank 51 and sludge digestion tank (Sludge Digestion tank) 6; waste water first passes through grid 1 and grit chamber 2 to remove insoluble solids, including large solids, dander, hair and floating debris, and then flows into flow regulation Pond 3 carries out preliminary treatment, then flows into primary biochemical pool 4 to carry out primary biochemical treatment, then flows into primary sedimentation tank 41 to carry out mud-water separation treatment for the first time, and the supernatant liquid of mud-water separation treatment ...

Abstract

The invention relates to a wastewater treatment process, in particular to a new wastewater treatment process using pure microorganisms to treat high-concentration industrial wastewater, including a grid, a grit chamber, a flow regulation pool, a primary biochemical pool, a primary sedimentation tank, and a secondary biochemical Pool, secondary sedimentation tank and digestion tank, adding compound microbial preparations in the flow regulating tank, primary biochemical pool, secondary biochemical pool and digestion tank; the present invention does not need to use chemicals for sewage treatment, and the activated sludge produced can digest itself , The amount of sludge discharged to the environment is small, which not only effectively reduces the generation of stench, but also has high sewage treatment efficiency, can effectively treat high-concentration sewage, and can effectively treat various sewage with a COD value below 15000mg / L.

Description

technical field [0001] The invention relates to a waste water treatment process, in particular to a novel waste water treatment process for treating high-concentration industrial waste water with pure microorganisms. Background technique [0002] At present, most of the wastewater treatment systems in the tanning industry adopt a physical-chemical plus biochemical treatment process. Due to the complexity of the process, many influencing factors, and high difficulty in process control, the treatment effect is often unstable, and chemical agents are added for coagulation. Precipitation leads to the generation of a large amount of sludge, and the so-called sludge digester is used to acidify and hydrolyze the sludge produced by chemical agents, which cannot achieve the purpose of real "digestion", and not only produces a large amount of pollution to the environment Sludge pollutes the environment, and the odor is serious, and the uncontrollable stench has a huge impact on the su...
