Highly effective aerobic biochemical water purification agent

Abstract

The aerobic biochemical water purifying agent consists of aluminum sulfate 70-80 wt%, lignin 10-15 wt% and Chinese medicinal stone 10-15 wt%. It has added RE biological additive, no bacteria seed and no enzyme. After being thrown into aerobic biochemical tank, it can culture great amount of robust indigenous zoogloea and result in magic biochemical effect. The present invention has the advantagesof small thrown amount, high economic benefit, convenient use, high outgoing water quality, etc.

Description

technical field [0001] The invention relates to a sewage purifying agent, in particular to an aerobic high-efficiency biochemical water purifying agent. Background technique [0002] At present, most of the sewage purifiers sold in the domestic and foreign markets are physical and chemical agents such as polyalumina (PAC, polyaluminum, basic aluminum chloride), aluminum sulfate, polyferric sulfate (EPS, polyferric, sulfur comb iron) ), iron trioxide, ferrous sulfate (green vitriol, ferrous vitriol) and other inorganic coagulants and organic polymer flocculants (PAM), can only be used for the primary treatment of the primary settling tank and the effluent after the secondary settling tank reaches the standard subsequent processing. Because physical and chemical agents are not beneficial to the aerobic biochemical pool, they must not be added in front of the aerobic biochemical pool. Otherwise, not only will it not help the biochemical action in the aerobic biochemical pool, ...

AI Technical Summary

Problems solved by technology

Because physical and chemical agents are not beneficial and harmful to the aerobic biochemical pool, they must not be added in front of the aerobic biochemical pool, otherwise they will not help the biochemical action in the aerobic biochemical pool, but will lead to the death of the original normal microorganisms in the pool

The shortcomings of physical and chemical agents are: large amount of agents, high growth and operation costs, slow aggregation speed, more sludge growth and not easy to dehydrate, less oxygen content in sludge, more odors to form secondary pollution, after treatment Insufficient oxygen content in the water and other problems

There are water purification products with bacteria or enzymes in foreign countries, but they have obvious limitations: (1), the price is high, taking American products as an example, the market price per ton of the product is 30,000 US dollars; (2), there is no General applicability, that is, one strain can only produce one kind of microorganism in a targeted manner; (3), water purifiers with strains cannot adapt to the harsh real environment of domestic sewage, that is, they die immediately after being put into an aerobic biochemical pool

Moreover, my country has extremely strict animal inspection and quarantine restrictions on the import of bacteria-carrying products, which also inhibits the use of imported products to a certain extent.
