Composite strain biological fluid bed membrane method and anaerobic filler preparation method

Abstract

The invention provides a composite strain biological fluidized bed membrane method which comprises the following steps: anaerobic tank treatment: an anaerobic filler is arranged in an anaerobic tank,sewage accounting for 5-30% of the mass of a water body in the anaerobic tank is introduced into the anaerobic tank to be treated, and the treatment time is 4-24 hours; treatmentin a first sedimentation tank: the sewage is introduced into the first sedimentation tank to be subjected to sedimentation treatment for 1-6 hours; treatment in an aerobic tank: anaerobic filler is arranged in the aerobictank, the aerobic filler accounts for 5-30% of the mass of the water body in the anaerobic tank, the sewage is introduced intothe aerobic tank to be treated, and the treatment time is 2-12 hours; treatment in a second sedimentation tank: the sewage is introduced intothe second sedimentation tank to be settled for 1-6 hours. The invention also provides a preparation method of the anaerobic filler.According to the method, an effective sheltering space can be provided for mixed strains, the propagation speed of the strains is increased, dominant bacterial colonies are established for the targetstrains in the sewage, and therefore the sewage purification rate is increased.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a compound bacterial species biological flow bed membrane method and an anaerobic filler preparation method. Background technique [0002] With the continuous acceleration of China's urbanization process, the urban population is also increasing, and the scale of the city is constantly expanding, which puts forward higher requirements for the supporting facilities of the city, especially for the supporting facilities of urban residents' domestic waste. Facilities, because they are urban sewage, have their own harmful properties and have the characteristics of long duration and high pollution degree, so timely and efficient urban sewage is a research hotspot in this field. [0003] For urban sewage, it has its own distinctive characteristics, that is, it contains a large amount of organic substances, such as starch, protein, oil, etc., and a large amount of inorganic subst...
