Abstract

The invention discloses a domestic sewage treatment station tail water upgrading process system which comprises a gallery ditch defined by a plurality of forming modules, a biological ceramsite layer which fills or is mounted in the gallery ditch and a biological filler layer, and a water distribution system device arranged between the biological ceramsite layer and the biological filler layer, and the water distribution system device is connected with a tail water outlet of the sewage treatment station. The system can adapt to a side slope hardened river channel, the flood discharge function is not affected, the multistage anaerobic oxidation technology and the microorganism solidification technology are efficiently utilized, the microorganism improvement effect is achieved, and the specific effects include that the purification efficiency is high, and the effluent quality is good, occupied area is small, and construction is flexible; and the construction and operation cost is low.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to sewage treatment facilities. Background technique [0002] my country's "14th Five-Year Plan" has made a systematic and comprehensive plan for the improvement of the domestic water ecological environment: on the one hand, it has improved the water quality assessment targets of rivers and lakes; It can be said that the requirements for improving the quality of water environment are becoming more and more urgent and strict. However, the water quality of most of the domestic sewage centralized treatment stations that have been built and put into operation can only meet the first-class A standard, which is far below the requirements of Class III and Class II for the assessment of water quality in rivers and lakes during the "14th Five-Year Plan". Central Environmental Protection's call for the transformation of the old station is also getting stronger. [0003] The...
