Abstract

The invention discloses a method used for increasing sewage processing biomembrane formation speed and stability, and belongs to the technical field of sewage processing. According to the method, extraction and concentration of an active sludge sample in aerobic or anaerobic biomembrane sewage processing technology are carried out, ultra high performance liquid chromatography tandem electro-sprayion source analysis is adopted in analysis of AHL quorum sensing signals of the active sludge sample, quantitative calculation is carried out to determine AHL signal molecular type and using amount, and at last, exogenous AHLs signal molecules are added into aerobic or anaerobic biomembrane sewage processing technology based on the determined type and using amount, and synchronous nitrogen and phosphorus removal is realized. According to the method, analysis on flora AHL signal in biomembrane formation process is adopted, biomembrane formation speed is accelerated, and at the same time, the stability of the formed biomembrane is increased greatly. The method is capable of solving problems in the prior art that biomembrane formation early stage system operation is not stable, and biofilm culturing time is long. The method is adopted in regulation and control of biomembrane sewage processing technology starting phase, so that cost is reduced greatly.

Description

technical field

[0001] The invention relates to a method for improving the formation speed and stability of sewage treatment biofilm, which belongs to the technical field of sewage treatment. Background technique

[0002] With the development of my country's economic level, the amount of sewage in cities and villages is increasing day by day. The traditional sewage treatment process such as A 2 O. The operation of oxidation ditch is not stable enough, it occupies a large area, and it is easy to generate sludge bulking and large sludge output, which seriously limits the treatment efficiency of the sewage plant and has adverse effects on the surrounding environment. The biofilm process has the advantages of stable operation, less residual sludge, simple management, strong ability to remove ammonia nitrogen and refractory pollutants, etc. It can adapt to a wide range of water quality changes, and has attracted great attention in recent years. The biofilm wastewater treatment ...
