Pollutant biodegradation reaction device

Abstract

The invention relates to the technical field of pollutant biodegradation, and discloses a pollutant biodegradation reaction device which comprises a device box body, and an aeration mechanism and a biological separation mechanism are arranged in the device box body; the aeration mechanism comprises a first annular pipe, a second annular pipe, a first water pipe, a second water pipe, a first air pump, a third water pipe, a fourth water pipe, a second air pump, a first spray pipe, a second spray pipe, a first spray head and a second spray head. The two annular pipes are arranged in the device box body, the spray heads are arranged on the annular pipes, annular aeration can be carried out on water from the upper end and the lower end at the same time, an annular aeration mechanism is utilized, the aeration area in the water is increased, the aeration efficiency and the aeration effect in the water are improved, and the separation nets are arranged in the annular pipes, impurities in sewage can be prevented from entering the water center position through the separation net, and when the two annular pipes are flushed, the surfaces of the separation nets in the opposite annular pipes can be cleaned and flushed mutually.

Description

technical field [0001] The invention relates to the technical field of pollutant biodegradation, in particular to a pollutant biodegradation reaction device. Background technique [0002] At present, there are hundreds of thousands of known environmental pollutants, most of which are organic substances. Organic substances can undergo photolysis, chemical decomposition, and biological decomposition in the environment. Among them, biological decomposition has the greatest effect, and the activities of microorganisms are also harmful to heavy metal mercury. The methylation of arsenic and selenium plays an important role. Microbial cells can resist the toxicity of heavy metals by relying on general and specific mechanisms, and can use the characteristics of microorganisms to purify polluted water. Bioremediation is a booming development in the past ten years. A technology for controlling environmental pollution. [0003] Patent No. CN202022240320.8 discloses a pollutant biodegr...

AI Technical Summary

Problems solved by technology

[0004] However, in the existing pollutant biodegradation reaction device, the aeration effect is not very good during use, and the aeration cannot be performed quickly. At the same time, during the aeration process, the sludge at the bottom cannot be pushed up to avoid the sludge Attached to the inner wall, not only that, when aerating, the separation net cannot be cleaned, and the problem of microbial loss on the microbial culture carrier cannot be completely solved
