Problems solved by technology

[0003] However, in practical applications, decentralized domestic sewage treatment equipment will have problems such as low sewage treatment efficiency, high operation and maintenance costs, and difficult operation. From the perspective of practical application, integrated sewage treatment equipment is especially suitable for small water volume, The scattered layout has the advantages of small footprint and short construction period. It has been applied in many areas in China, but there are still problems of low sewage treatment efficiency and substandard water discharge.

Abstract

The invention provides an intelligent integrated deep denitrification sewage treatment system based on an SND process. The sewage treatment system comprises a pretreatment system, a biochemical treatment system, a deep treatment system and an intelligent management and control system platform, wherein the biochemical treatment system comprises an SND reaction tank, an anoxic tank, an aerobic tank and a membrane bioreactor (MBR) tank; the SND reaction tank, the anoxic tank, the aerobic tank and the MBR tank are used for treating sewage in sequence; nitrification liquid in the aerobic tank flows back to the anoxic tank and the SND reaction tank; sludge in the MBR tank flows back to the SND reaction tank. The intelligent integrated deep denitrification sewage treatment system based on the SND process can intelligently and efficiently realize that the effluent of sewage treatment reaches the standard, so that the sewage is recycled in a green manner, and the pollution of a water body drainage basin is reduced.

Description

technical field [0001] This application relates to the field of sewage treatment, in particular to an intelligent integrated deep denitrification sewage treatment system based on SND technology. Background technique [0002] At present, my country's decentralized domestic sewage treatment methods mainly include integrated sewage treatment equipment with activated sludge method and biological contact oxidation method as the core technology, and ecological treatment scheme with artificial wetland, oxidation pond and stabilization pond as the core, etc. . [0003] However, in practical applications, decentralized domestic sewage treatment equipment will have problems such as low sewage treatment efficiency, high operation and maintenance costs, and difficult operation. From the perspective of practical application, integrated sewage treatment equipment is especially suitable for small water volume, The scattered layout has the advantages of small footprint and short constructio...
