Abstract

The invention relates to the field of pollutant controlling, and specifically relates to a vegetable tannin algae inhibitor and a method for inhibiting the overgrowth of algae in eutrophicated fresh water areas. The vegetable tannin algae inhibitor provided by the invention comprises one or more components selected from gentisic acid, ellagic acid, and tannic acid. All the components of the algaeinhibitor can be obtained through artificial synthesizing, and are cheap in price. The preparation method of the complex agent is simple, and has a strong operability. With the algae inhibitor, secondary pollution to the environment is not caused, water areas can be prevented from water bloom, and the stability of aquatic ecosystems can be maintained. With the complex algae inhibitor provided by the invention, over dose of single component can be effectively avoided, such that the damage to the aquatic ecosystems can be prevented, and various degrees of drug resistances gradually generated inalgae caused by long-term and repeated usage of single algae inhibitor can be effectively overcome or retarded. Also, with the algae inhibitor, algae inhibiting capacity and broad spectrum property of the algae inhibitor can be effectively improved.

Description

technical field

[0001] The invention relates to the field of object pollution control. Specifically, the invention relates to a plant tannin algae inhibitor and a method for inhibiting the excessive growth of algae in eutrophic freshwater water bodies. Background technique

[0002] Economic development and rapid population increase have contributed to the deterioration of the water environment and ecological environment, especially the pollution of eutrophication in urban water bodies, resulting in frequent occurrence of algal blooms in surface water bodies. , the dissolved oxygen decreases, the transparency decreases, and the toxic algae will release toxic substances into the water body, endangering aquatic organisms and even human health.

[0003] Chemical methods are commonly used to control the overgrowth of algae in water bodies. Chemical methods include chemical precipitation, acid-base neutralization, and adding algaecides. The precipitation method reduces N and P by...
