Blue algae scavenger using illite as carrier and preparation method thereof

Abstract

The invention belongs to the field of water pollution treatment, in particular relates to a water body algae scavenger and a preparation method thereof. A blue algae scavenger taking illite as a carrier is characterized in that the blue algae scavenger is prepared by a cerous nitrate solution, a sodium hydroxide solution and granular illite raw materials, wherein the addition amount of the sodiumhydroxide solution is 1 to 5 percent of the volume of the cerous nitrate solution, and the addition amount of the granular illite is 5 to 30 percent of the total mass of the cerous nitrate solution and the sodium hydroxide solution; the mass concentration of the cerous nitrate solution is between 0.1 and 0.5 percent, and the mass concentration of the sodium hydroxide solution is between 5 and 10 percent; and the granularity of the granular illite is less than 200 meshes, and the mass concentration of the granular illite is more than 80 percent. The blue algae scavenger prepared by the method has the advantages of good blue algae removal effect, quickness in taking effect, low cost and no secondary pollution.

Description

A kind of cyanobacteria scavenging agent taking illite as carrier and preparation method thereof technical field The invention belongs to the field of water pollution control, and in particular relates to a water body algae scavenger and a preparation method thereof. Background technique Driven by the rapid development of the regional economy, the over-exploitation of water resources and the neglect of environmental protection have made the water environment in most parts of our country worsen day by day, and the eutrophication of water bodies is serious. The eutrophication of the water body leads to the excessive reproduction of algae in the water body, especially the outbreak of planktonic algae (mainly cyanobacteria) and the formation of water blooms. In recent years, in my country's Dianchi Lake, Taihu Lake, Chaohu Lake, Erhai Lake and other water bodies, cyanobacteria outbreaks have occurred frequently. A large number of algae blooms not only affect the landscape eff...
