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...

Problems solved by technology

The chemical algae removal method is to add algicide in the water body. This method has immediate effect, but it is difficult to cure the root cause, and the secondary pollution is serious; "Algaecide" is used to eliminate algae such as blue-green algae in rivers, lakes, and ponds. This algaecide uses polyaluminum chloride and zeolite powder for flocculation and adsorption to remove algae. Aluminum itself has certain hazards to aquatic animals, and it is only a simple algae removal, removing cyanobacteria and other algae together, which is not good for the algae ecological structure of the water body; the microbial method is to add beneficial microbial agents (such as photosynthetic bacteria preparations, etc.), and cyanobacteria Competing for nutrients and reducing the density of blue-green algae, this method is an environmentally friendly treatment method, without secondary pollution, but the effect is unstable, and it is usually difficult for exogenous microorganisms to grow and reproduce better; the physical method is to install water pumps, aerators, etc. means to increase water flow and reduce algae reproduction. This method is usually only an auxiliary measure with high energy consumption; the main technical means of ecological management methods is to build aquatic plants, aquatic animals, and water micro-ecological systems to form better aquatic ecosystems. The biological chain makes the nutrient salt have a virtuous cycle, maintains a low nutrient salt concentration in the water body, and finally achieves the purpose of avoiding the excessive reproduction of blue-green algae. The ecological management method is an ideal blue-green algae treatment plan for large-scale water bodies, but it is limited by the site and funds. Restricted small polluted water bodies, engineering implementation and management are more difficult
