Problems solved by technology

[0003] At present, in sewage treatment, sewage is injected into a regulating tank for pre-sedimentation, and then the settled sewage to be treated is pumped to an inclined tube sedimentation tank for dosing to aid sedimentation, followed by hydrolytic acidification treatment and contact oxidation treatment. This treatment method It has the following disadvantages: 1. It is easy to damage the inclined tube in the inclined tube pool, which increases the maintenance cost of the enterprise; 2. The settlement effect is not good, which makes the influent water quality unstable, resulting in an increase in the amount of dosing, which increases the production cost of the enterprise; 3. Settlement The effect is not good, the amount of dosing is not easy to determine, resulting in the discharge of water quality indicators are not up to standard

Abstract

The invention discloses a sewage treatment method and a special adjustment tank for the same. The sewage treatment method and the special adjustment tank for the same are characterized by being implemented through steps of sewage collection, filter pressing, preliminary sedimentation of the adjustment tank, inclined pipe sedimentation, hydrolysis acidizing treatment, contact oxidation, natural sedimentation and the like. Compared with the prior art, the sewage treatment method and the special adjustment tank for the same have the advantages that production cost and maintenance cost can be effectively saved during sewage treatment, sewage inflow quality is balanced, discharged water quality is up to standard, and production sewage can be effectively treated.

Description

technical field [0001] The invention relates to a sewage treatment method suitable for sewage treatment in the EPS industry and a special regulating pool thereof. Background technique [0002] In the daily production of industrial enterprises, a large amount of production sewage will be produced along with the production. If the production sewage is discharged directly without treatment, it will not only cause serious pollution to the environment, but also seriously damage the ecological balance. Therefore, sewage treatment is an important problem that enterprises must face in practice. [0003] At present, in sewage treatment, sewage is injected into a regulating tank for pre-sedimentation, and then the settled sewage to be treated is pumped to an inclined tube sedimentation tank for dosing to aid sedimentation, followed by hydrolytic acidification treatment and contact oxidation treatment. This treatment method It has the following disadvantages: 1. It is easy to damage t...
