Plant leaching solution based compound algistat

Abstract

The invention discloses a plant leaching solution based compound algistat which is used for inhibiting algae to over-grow in eutrophic fresh water body, preventing and eliminating algal bloom generation of fresh water; the constituents are as follows by weight percentage: 50-80 percent of plant leaching solution, 5-30 percent of gallic acid and 5-30 percent of tea polyphenol; the plant leaching solution adopts apple leaching solution, grape leaching solution and onion leaching solution; by adopting the plant leaching solution based compound algistat which is used for inhibiting algae to over-grow in eutrophic fresh water body, preventing and eliminating algal bloom pollution of fresh water has the advantages of high efficiency, low cost, no secondary pollution and easy operation, therefore, the plant leaching solution based compound algistat is not only suitable for small closed water bodies, but also is suitable for large slow-flowing water areas.

Description

technical field [0001] The invention relates to an environment treatment technology for water bloom pollution, and more specifically relates to a plant leaching liquid-based composite algae inhibitor for inhibiting the excessive growth of algae in eutrophic freshwater water bodies and preventing and eliminating the occurrence of freshwater blooms. Background technique [0002] At present, the eutrophication of natural water bodies has become one of the major environmental pollution problems facing the world. In China, the problem of eutrophication in freshwater lakes and reservoirs is very serious. In addition to the three major freshwater lakes, Dianchi Lake in Yunnan, Taihu Lake in Jiangsu and Chaohu Lake in Anhui, which have been severely polluted by cyanobacteria blooms, many lakes and reservoirs in the middle and lower reaches of the Yangtze River and the Yellow River are also polluted. Different degrees of cyanobacterial blooms have occurred successively and the presen...

Problems solved by technology

[0012] Aiming at the deficiencies of the prior art in controlling the growth of freshwater eutrophic algae and controlling the pollution of algal blooms, the purpose of the present invention is to provide a new method for inhibiting the excessive growth of algae in eutrophic freshwater bodies, preventing and eliminating the occurrence of freshwater algal blooms. Plant leaching liquid-based compound algae inhibitor to solve the biological safety hazards caused by the introduction of foreign microorganisms existing in the existing freshwater eutrophication water bloom pollution control technology, the algae inhibition effect is weak, affecting the appearance of the water surface, poor practicability or scope of application limited and many other issues
