Blue algae scavenger using diatomite 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 scavenging agent and a method for preparing the same. A blue algae scavenging agent using diatomite as a carrier is characterized in that the blue algae scavenging agent is made from cerous nitrate solution, sodium hydroxide solution and granular diatomite as raw materials, the added quantity of the sodium hydroxide solution is 1 to 5 percent of the volume of the cerous nitrate solution, and the added quantity of the granular diatomite is 5 to 30 percent of the total mass of the cerousnitrate solution and the sodium hydroxide solution, wherein the mass concentration of the cerous nitrate solution is 0.1 to 0.5 percent, and the mass concentration of the sodium hydroxide solution is5 to 10 percent; and the granularity of the granular diatomite is smaller than 200 meshes, and the mass purity is larger than 80 percent. The blue algae scavenging agent prepared by the method has good scavenging effect for scavenging the blue algae, fast effect, low cost, and no secondary pollution.

Description

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 effect of water bodies, but also produce algae toxins, which pose a serious threat to water ecosystems...
