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 b...

Embodiment 1

[0022] Get 75 kilograms of iron-free aluminum sulfate prepared by crystallization, 13 kilograms of lignin and 12 kilograms of rare earth compounds extracted from food-grade rare earth medical stone ore by extraction and separation technology, and prepare a kind of aerobic high-efficiency biochemical purification agent of the present invention. Aqueous products. This product is used in the domestic sewage treatment of Shanghai Caoyang Sewage Treatment Plant. As a result, the domestic sewage can be reduced from about 60mg / L of ammonia-nitrogen and about 15mg / L of phosphorus TP to ≤15mg / L of ammonia-nitrogen and Tp≤1mg / L, meet the emission standard.

Embodiment 2

[0024] Get 70 kilograms of iron-free aluminum sulfate prepared by crystallization, 15 kilograms of lignin and 15 kilograms of rare earth compounds extracted from food-grade rare earth medical stone ore by extraction and separation technology, and prepare a kind of aerobic high-efficiency biochemical purification agent of the present invention. Aqueous products. This product is used in the printing and dyeing wastewater treatment of Zhejiang Shaoxing Water Treatment Development Co., Ltd. As a result, the CODcr (chemical oxygen demand) in the printing and dyeing wastewater can be reduced from 1800mg / L to ≤120mg / L, and the chromaticity can be reduced from about 450 (dilution times ) dropped to ≤50, SS (suspended solids) dropped from about 300mg / L to ≤30mg / L, meeting the discharge standard.

Embodiment 3

[0026] Take 80 kilograms of iron-free aluminum sulfate prepared by crystallization, 10 kilograms of lignin and 10 kilograms of rare earth compounds extracted from food-grade rare earth medical stone ore by extraction and separation technology, and prepare an aerobic high-efficiency biochemical compound of the present invention. Water purifier products. This product can be used for sewage treatment in general sewage treatment plants.

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 advantages of 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, ...
