Embodiment Construction

[0101] The present invention is a biological reaction sewage treatment method, comprising the following steps:

[0102](1) The industrial sewage is pretreated by the sewage pretreatment plant and then introduced into the mixed distribution tank of the comprehensive sewage treatment plant;

[0103] (2) Import domestic sewage into the mixed distribution tank of the comprehensive sewage treatment plant;

[0104] (3) Mix step (1) and step (2) and stay for 15 minutes, then distribute the sewage evenly to the AT-BC equipment after water distribution through the water distribution system;

[0105] (4) The mixed sewage in step (3) enters the AT-BC device, and absorbs and initially degrades the organic matter and ammonia nitrogen in the sewage by the Bacillus bacteria growing on the carrier in the AT-BC device;

[0106] (5) Step (4) The sewage treated by the AT-BC device is introduced into the aeration tank, and the Bacillus bacteria and other microorganisms in the aeration tank remov...

Abstract

The invention discloses a biological reaction sewage treatment method which comprises the following steps: (1) pretreating industrial sewage by a sewage pretreatment plant, and introducing the pretreated sewage into a mixed distribution reservoir of a comprehensive sewage treatment plant; (2) introducing domestic sewage into the mixed distribution reservoir of the comprehensive sewage treatment plant; (3) mixing the pretreated industrial sewage and domestic sewage, standing for 15 minutes, and equally distributing the sewage into AT-BC units by a water distribution system; and (4) sending the mixed sewage in the step (3) into the AT-BC units, and carrying out adsorption and primary degradation on organic matters and ammonia nitrogen in the sewage by using Bacillus carried in the AT-BC units. The biological reaction sewage treatment method overcomes the defects in the prior art, so that the water quality reaches the standard and is reliable and stable.

Description

technical field [0001] The invention relates to a biological reaction sewage treatment method, which belongs to the field of chemical industry. Background technique [0002] The selection of sewage treatment process is determined after comprehensive analysis and research based on factors such as sewage influent water quality, effluent standard, scale of sewage treatment plant, environmental capacity of discharged water body, current economic conditions, management level, natural conditions, and environmental characteristics. Each process has its own characteristics and applicable conditions, which should be determined in combination with the actual situation of the local area and the specific characteristics of the project. [0003] The selection principles of the sewage treatment plant process are as follows: 1. Advanced process performance: advanced and mature process, simple process, strong adaptability to water quality, high effluent compliance rate, and easy sludge trea...
