Fast biofilm formation device of suspended filler and sequencing batch biofilm reactor

Abstract

The invention relates to a fast biofilm formation device of a suspended filler and a sequencing batch biofilm reactor. The biofilm formation device comprises a filler basket formed by a skeleton and a wall net, wherein two baffle plates which are arranged in an inclined way are symmetrically distributed at the bottom of the filler basket; a V-shaped splash guard which opens downwards is arranged below the filler basket; a plurality of biofilm formation devices are respectively arranged in gaps of aeration discs of a biological reaction tank, so as to form the sequencing batch biofilm reactor. The fast biofilm formation device of the suspended filler in the invention is simple and reasonable in structure, can effectively avoid the shearing action to the biofilm on the surface of the filler by the aeration and reduce the washing action of water flow to the biofilm, thereby being beneficial to adhering, growing and updating of activated sludge; the sequencing batch biofilm reactor with the fast biofilm formation device of the suspended filler is simple in technological process, convenient in operation and using, convenient in daily overhauling and maintenance, good in purifying effect on waste water and sewage, high in purifying speed and easy to popularize.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a suspended filler rapid film-hanging device and a sequencing batch biofilm reactor. Background technique [0002] The increasingly serious environmental pollution is threatening the water sources and water bodies that human beings rely on for survival. Facing the current situation of my country's water resources, it is imperative to restore and purify the polluted or facing pollution of water resources. Biological treatment can effectively treat industrial wastewater and domestic sewage. Biofilm can be formed by adding fillers to the biological reaction tank, so as to adhere to microorganisms with a long generation time, prolong the biological food chain, make the microbial population appear natural classification, and increase the biomass. Therefore, the attachment, growth, and natural renewal of biofilm on the surface of the filler become the key to adding filler. ...

AI Technical Summary

Problems solved by technology

If the filler is placed directly in the biological reaction tank, the film formation will be slow or even fail due to the scouring effect of the water flow on the filler and the shearing effect of the air bubbles. In addition, this way of adding the filler will make the filler too dispersed, which is not conducive to maintenance during operation. update and management

Some existing suspended filler film-forming or film-forming devices have problems such as complex structure, constant use and maintenance, and unsatisfactory film-forming effects.
