Abstract

The invention discloses a cyanobacteria mud enhancing auxiliary agent and application in cyanobacteria mud processing thereof. The cyanobacteria mud enhancing auxiliary agent, which is measured by 100 weight portions, consists of the materials: aluminum iron line soluble salt: 10-50 portions; silicate mineral rock soil powder: 50-90 portions. The aluminum iron line soluble salt is mixture of aluminum chloride, aluminum sulfate, ferric sulfate, ferrous sulfate, polymeric aluminum chloride, polymeric ferric sulfate and polymeric aluminum ferric sulfate or mixture of any of aluminum chloride, aluminum sulfate, ferric sulfate, ferrous sulfate, polymeric aluminum chloride, polymeric ferric sulfate and polymeric aluminum ferric sulphate. The silicates mineral rock soil powder is the mixture of diatomite, fly ash, acid clay and bentonite or the mixture of any of diatomite, fly ash, acid clay and bentonite. Before the cyanobacteria mud enhancing auxiliary agent is used for the cyanobacteria mud processing, a reserved weight ratio of 10-30 percent of suspension liquid is prepared by the cyanobacteria mud enhancing auxiliary agent, then a weight ratio of 1-5 percent of the suspension liquid is added into the cyanobacteria mud. The invention has good dehydration effect, promptly control the serious threat caused by algae toxins and lays the solid foundation of the utilization of cyanophytes.

Description

technical field

[0001] The invention relates to a product for treating blue-green algae mud and its application in treating blue-green algae mud, more specifically, a kind of strengthening coagulant for blue-green algae mud and its application in treating blue-green algae mud. Background technique

[0002] With the rapid economic development of Taihu Lake and other inland lake basins, the pollutants discharged into rivers and lakes are increasing day by day, and the speed of pollution has exceeded the purification capacity of the lake body itself. The large discharge of some phosphorus and nitrogen-containing compounds has accelerated the The process of eutrophication in lakes leads to the abnormal reproduction and growth of algae, especially blue-green algae, which leads to the deterioration of water quality and frequent outbreaks of massive algae blooms, which not only destroys the healthy and balanced aquatic ecosystem, but also deteriorates the sensory properties of the w...
