Germ water purifying agent

Abstract

The invention discloses a germ water purifying agent. The germ purifying agent is characterized by comprising 5-12 parts of denitrifying bacteria, 5-12 parts of denitrifying bacteria, 5-12 parts of bacillus, 5-12 parts of photosynthetic bacteria, 8-12 parts of phosphorus-accumulating bacteria, 5-10 of saccharomycetes, and 2-8 parts of actinomycetes based on counting weight parts, and each gram medium of a single bacterium contains 2.5-3.2 hundreds of millions of bacteria. The germ water purifying agent has the advantages of being high-effciency, free of pollution, low in sewage treatment cost, little in investment, low in operation cost, strong in adaptability, low in mud output, and capable of possessing good economic and social benefit.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a microbial water purifying agent. Background technique [0002] The biological contact oxidation method is a biofilm process between the activated sludge method and the biological filter. The treatment structure of the biological contact oxidation method is a submerged aerated biological filter, also known as a biological contact oxidation tank. Filler is installed in the biological contact oxidation tank, the filler is submerged in wastewater, and the filler is covered with biofilm. During the contact process between wastewater and biofilm, the organic matter in the water is adsorbed by microorganisms, oxidized and decomposed and transformed into a new biofilm. The biofilm that falls off from the filler is removed after flowing into the secondary sedimentation tank with the water, and the waste water is purified. In the contact oxidation tank, the oxygen n...

AI Technical Summary

Problems solved by technology

Although the contact oxidation method has a strong resistance to organic load impact, but the concentration is too high or too low will affect the biological activity

When the concentration is high, it is difficult to supply oxygen, the biological activity is poor, and the film is not easy to fall off and renew: the concentration is too low, resulting in insufficient nutrition, and as a result, it is difficult to form a biofilm

[0003] Urban domestic sewage is a kind of sewage with complex components, including organic matter, inorganic matter, water-soluble, insoluble or water-insoluble compounds, as well as hospital waste water and industrial waste water mixed in it, and the flow rate is unstable and the composition large fluctuations

A considerable number of industrial polluting enterprises in our country would rather be punished than invest in wastewater treatment. Even if there is a sewage treatment plant, the operation is extremely abnormal. The lack of funds is the main reason for the serious lag of sewage treatment in our country.
