Abstract

The invention belongs to the field of water treatment and particularly relates to a biological membrane reactor. The biological membrane reactor comprises a sewage reaction tank, an aeration pipe and biological membrane filler; the aeration pipe is arranged in the sewage reaction tank and provided with a plurality of air outlet positions, and the biological membrane filler is filled in the sewage reaction tank and connected with the air outlet positions. By connection of the biological membrane filler with the aeration pipe, internal aeration of the biological membrane filler can be realized so as to make the interior of a biological membrane in an aerobic state, activity and proportion of aerobic microorganisms on the biological membrane can be increased beneficially, membrane forming time of sewage microorganisms on the surface of the filler is further shortened, and sewage degradation efficiency is improved. According to experiments, compared with a traditional biological membrane reactor under same conditions, the biological membrane reactor has advantages that membrane forming time is shortened by 17 days, biological membrane thickness is increased by 10.42% after maturity, effluent TN is smaller than 10mg / L, COD is smaller than 50mg / L, and BOD is smaller than 10mg / L.

Description

technical field

[0001] The invention belongs to the field of water treatment, in particular to a biofilm reactor. Background technique

[0002] In recent years, with the rapid economic development, my country has also brought a series of environmental problems while pursuing GDP growth. Among them, the shortage of fresh water resources makes urban domestic sewage treatment technology particularly important. However, with the improvement of people's living standards, the content of nitrogen and phosphorus in urban domestic sewage increases, and the organic components are complex. The traditional biological sewage treatment technology has been unable to keep up with the pace, and the treatment effect is not good. The characteristics of high efficiency, less residual sludge production, and convenient operation and management have been rapidly developed, and have broad application prospects in sewage treatment.

[0003] The so-called biofilm method refers to the method of treat...
