Abstract

The invention relates to a new type algae-resisting coating. According to weight percentage, the raw materials for preparing the coating comprise 40 to 60% of resin mixture of MEG resin and synthetic resin and 60 to 40% of organic solvent, wherein the MEG resin is 20 to 80% of the resin mixture. The invention also discloses an algae-resisting net for treating the algae water pollution in lake and library. The new type algae-resisting coating and the algae-resisting net technique can efficiently and durably treat the algae in lake and library. Through a plenty of tests, emergency and prevention are both tested. Grasses are planted on bottom silt so as to form a large area of plant cover, which is in favor of environmental restoration of the lake, and can treat both the symptoms and root causes.

Description

technical field [0001] The invention relates to a coating, in particular to a novel anti-algae coating, and also relates to a preparation method of the novel anti-algae coating and an application for treating algae water bodies in lakes and reservoirs. Background technique [0002] About 70% of the world's lakes are distributed with cyanobacteria, which can bring devastating harm to lakes. Since the beginning of the 21st century, global climate warming, ecological environment continues to deteriorate, and nutrients such as nitrogen and phosphorus discharged into lakes and reservoirs Substances continue to increase, and the eutrophication of water bodies is intensified, which in turn leads to more frequent and larger scale algal blooms in water bodies. According to science, severe algal blooms will cover the water surface, prevent chemical synthesis and atmospheric exchange in the water body, rapidly reduce the concentration of dissolved oxygen in the water, cause the death o...
