Embodiment 1

[0010] Example 1: The sugar used in this example is commercially available food-grade glucose, and the bacteria solution used is the water purification compound bacteria solution (containing photosynthetic bacteria, actinomycetes, yeast, etc.) produced by Kunming Shenghe Biotechnology Co., Ltd. bacteria, lactic acid bacteria, bacillus, etc., the number of beneficial viable bacteria is more than 3 billion / ml), the test was carried out in a white rectangular plastic bucket with a volume of 170L, and the inferior V eutrophication polluted water (northeast of Dianchi Lake) was extracted by a submersible pump The polluted water along the coast) 150L into the bucket, the test water has a large amount of cyanobacteria, and the transparency is about 10cm. No. 1 bucket is used as a blank control, and nothing is put into it; No. 2 bucket is put into the above-mentioned water purification compound bacterial solution 15ml, as a comparison of conventional microbial method; No. 3 bucket, fir...

Embodiment 2

[0013] Example 2: The sugar used in this example is saccharified by commercially available corn flour, amylase, glucoamylase, water, and calcium chloride according to a conventional method, and the final glucose content is 18%. The water quality improver (including photosynthetic bacteria, Bacillus subtilis, actinomycetes, lactic acid bacteria, etc., the number of beneficial viable bacteria is more than 2 billion / ml) produced by Fenhe Amino Acid Factory in Duqu was tested in a white rectangular plastic with a volume of 170L. It was carried out in a bucket, and 150L of inferior V eutrophication polluted water (polluted water along the northeastern coast of Dianchi Lake) was pumped into the bucket through a submersible pump. The tested water had a large amount of cyanobacteria and a transparency of about 10cm. , set up three plastic buckets, No. 1 bucket is used as a blank control, and nothing is put into it; No. 2 bucket is put into the above-mentioned water quality improving ag...

Abstract

The invention relates to a governance of water body eutrophication and blue algae breakout, belonging to environmental protection field. The invention provides the technical proposal that the application of a sugar reinforced microorganism method governs the water body eutrophication and blue algae breakout; the glucide is put into a bacterial liquid of microorganism in the eutrophied and polluted water body in weight radio of 1 to 5:1. When the bacterial liquid of microorganism plunged into the water body, putting in the glucide of a certain class and proportion can provide more feasible development condition for the ecdemic bacteria in the water body, help the ecdemic bacteria adapt to the water body environment rapidly, and simultaneously provide carbon source which the bacteria in reproduction needs in order to achieve the goals of great microorganism reproduction.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to the treatment of eutrophication of water body and cyanobacteria outbreak. Background technique [0002] Eutrophication pollution of lakes and other water bodies has become a worldwide problem and problem. Large and small lakes all over the world have appeared or have appeared to varying degrees due to agricultural non-point source pollution, urban life pollution, and industrial pollution. The eutrophication problem in the water body, the accumulation of nitrogen and phosphorus eutrophication components in the water body exceeds the self-purification ability of the water body, and when encountering a suitable temperature, it will lead to a large number of algae in the water body, especially the original ecological cyanobacteria. Due to the serious consequences of cyanobacteria outbreaks, such as: a sharp drop in dissolved oxygen in the water body, turbidity in t...
