Description

Combined aeration device of sewage biochemical treatment tank

Technical Field

The utility model relates to the technical field of sewage treatment equipment, in particular to a combined aeration device of a sewage biochemical treatment tank.

Background

Municipal sewage is domestic sewage, industrial wastewater and runoff sewage in the urban area. Generally, the sewage is collected by urban canals and is discharged into water after being treated by an urban sewage treatment plant. In addition to containing a large amount of organic matters, germs and viruses in urban sewage, due to the advanced development of industry, the water quality of industrial wastewater (accounting for about 60-80% of the total amount of the urban sewage) is increasingly complex, and the pollution of runoff sewage is increasingly serious, so that the urban sewage contains various toxic and harmful pollutants of various types and degrees. The treatment of urban sewage involves many aspects, and the comprehensive planning must be carried out on the sewer system, the position and treatment process of sewage treatment plants, the utilization and discharge requirements of the treated sewage and the like.

The biochemical treatment is simply referred to as biological treatment or biochemical treatment. The treatment process of the method is a sewage treatment method which mixes and contacts the waste water or the solid waste with microorganisms, decomposes organic matters and certain inorganic poisons such as cyanides, sulfides and the like in the waste water by utilizing the biochemical action in the microorganisms and converts unstable organic matters and inorganic poisons into nontoxic substances. The aerobic biological treatment and the anaerobic biological treatment can be divided according to the existence of oxygen in the reaction process.

An apparatus structure commonly used in aeration tanks in biochemical treatment; the existing aeration equipment is easy to have the problem of blockage; secondly, because the amount of treated water is not fixed, the aeration tank can not be accommodated sometimes, and the aeration tank can not be filled sometimes, so that the treatment effect is greatly influenced.
