Problems solved by technology

[0002] The eutrophication of lakes and reservoirs is mainly manifested in the fact that nutrients such as nitrogen and phosphorus in the water exceed the self-purification capacity of lakes and reservoirs, which in turn causes excessive growth and reproduction of harmful algae, resulting in serious ecological, resource and environmental problems and major economic losses.

Abstract

The invention provides an immobilized algae-lysing microorganism as well as a preparation method and an application thereof. The immobilized algae-lysing microorganism is prepared from raw materials in percentage by mass as follows: 40%-60% of algae-lysing microorganisms, 30%-50% of a carrier and 10%-20% of an immobilization material, wherein the algae-lysing microorganisms are one or more of bacillus, streptomyces, pseudomonas, sphingomonas, mycobacterium and shewanella with algae-lysing activity and are liquid, powdery or granular substances, with the viable count not lower than 1.0*10<10> cfu / g. The immobilized algae-lysing microorganism has a large specific surface area, good adsorption performance, high algae-lysing efficiency and environment adaptability, no secondary risk and the like, particularly has remarkable algae-lysing effects on microcystis, anabaena, aphanizomenon and other typical harmful algae and has better application prospects in the field of bioremediation of eutrophic water.

Description

technical field [0001] The invention belongs to the technical field of cyanobacteria bloom control and treatment, and in particular relates to an immobilized algae-dissolving microorganism and its preparation method and application. Background technique [0002] The eutrophication of lakes and reservoirs is mainly manifested in the fact that nutrients such as nitrogen and phosphorus in the water exceed the self-purification capacity of the lakes and reservoirs, which in turn causes excessive growth and reproduction of harmful algae, resulting in serious ecological, resource and environmental problems and major economic losses. In recent years, large-scale and high-frequency water blooms have occurred in Taihu Lake, Dianchi Lake, Chaohu Lake and Wuhan East Lake in my country. The algal toxins secreted by Microcystis, A. and algae organic matter seriously endanger the safety of drinking water quality and the living environment of animals and plants in the water body. Eutrophic...
