Water plankton biology regulating agent and its method for controlling water blue-green algae over propogation

Abstract

The ecological water plankton regulating agent consists of gypsum powder 30-40 wt%, attapulgite powder 20-40 wt% and sodium humate 30-40 wt%. The method of utilizing the ecological water plankton regulating agent in controlling excessive propagation of blue-green algae in water is to dilute the ecological water plankton regulating agent with 10-20 times water to obtain suspension and spreading the suspension to the water, with the applied amount of the ecological water plankton regulating agent being 3-10 g / cu m. The said regulating agent and method can control the excessive propagation of blue-green algae, ensure the algae diversity, raise the transparency of water and lower the content of microcystin in water.

Description

technical field

[0001] The invention relates to a planktonic eco-regulator mainly used for controlling lakes, rivers and ponds, which is an over-breeding blue-green algae, and an application method thereof. Background technique

[0002] In urban lakes and rivers, blue-green algae overgrowth is a common environmental problem. In high-density aquaculture pond water, the phenomenon of cyanobacteria overgrowth often occurs. The overgrowth of cyanobacteria in the water body not only affects the landscape, but also seriously affects the function of the water body. The overgrowth of cyanobacteria in the aquaculture water body will directly endanger the aquaculture production. The overgrowth of cyanobacteria is mainly caused by the excessive concentration and improper proportion of nutrients in the water body, which are induced in high temperature weather. Controlling the overgrowth of cyanobacteria is an important issue in water environment protection. The technologies currently...
