Embodiment Construction

[0011] In order to be able to understand the above objects, features and advantages of the present invention more clearly, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0012] The present invention provides a BRGA municipal sewage treatment method, comprising: a pre-sedimentation tank 1, a selective high-efficiency biological reactor 2, a gradient biochemical aeration tank 3, a microbial growth promoter 4, and a sedimentation tank 5. Pre-sedimentation in tank 1; Selective high-efficiency bioreactor 2 is set in the front section of gradient biochemical aeration tank 3 to treat sewage, and microbial growth promoter 4 is added at the same time; in gradient biochemical aeration tank 3, the sewage is subjected to gradient Biochemical aeration treatment; treated sewage is settled in a sedimentation tank5.

[0013] The BRGA municipal sewage treatment method provided by the present invention is b...

Abstract

The invention provides a BRGA municipal sewage treatment method. The method involves a pre-settling tank, a selective efficient bioreactor, a gradient biochemical aeration tank, a microbial growth accelerant and a settling tank. Municipal sewage pre-settles in the pre-settling tank; the selective efficient bioreactor is arranged at the front section of the gradient biochemical aeration tank for treating the sewage, and meanwhile the microbial growth accelerant is added; the sewage is subjected to gradient biochemical aeration treatment in the gradient biochemical aeration tank; the treated sewage settles through the settling tank. The BRGA municipal sewage treatment method is based on the decomposition pollutant effective strain superiority principle, and when the feed water quality and condition of the to-be-treated sewage change, an efficient purification function can still be kept by properly changing operating parameters of major facilities and pertinently adding the microbial growth accelerant.

Description

technical field [0001] The invention relates to the technical field of water pollution treatment, in particular to a BRGA municipal sewage treatment method. Background technique [0002] With the development of economy and the improvement of people's quality of life, the quality of sewage has also undergone some changes. With the rise of industry, some municipal sewage systems inevitably also accept part of the treated industrial sewage. At present, the new municipal sewage treatment facilities are difficult to achieve the goal of stable compliance throughout the year in the actual project, and the treatment process used needs to be improved. SUMMARY OF THE INVENTION [0003] The technical problem solved by the present invention is to solve the problems raised in the above background technology through a BRGA municipal sewage treatment method. [0004] The invention provides a BRGA municipal sewage treatment method, comprising: a pre-sedimentation tank, a selective high-...
