Algae removal type water purifying agent

Abstract

The invention relates to an algae removal type water purifying agent, which belongs to the water purifying agent for rice field, fish ponds and foaming lakes with algae, which solves the problems of the pollution and toxic hazard due to the use of copper sulfate and herbicides in the rice fields, fish ponds and foaming lakes as well as the manual salvage in water. The application of the copper sulfate and herbicides in the prior art has the disadvantages of high cost, insignificant effect and serious toxic damage to plants and organisms. The algae removal type water purifying agent is prepared with calcium nitrate, aluminum sulfate and ferrous sulfate mixed according to a weight ratio, wherein the weight ratio of the calcium nitrate, the aluminum sulfate and the ferrous sulfate is (1-2.0): (0.5-0.8): (0.2-0.5). The algae removal type water purifying agent of the invention can increase the yield of the rice fields, and make the water surfaces of the fish ponds and foaming lakes clean and fresh without any odor. Moreover, the algae removal type water purifying agent of the invention has the advantages of low cost and obvious effect on algae removal.

Description

technical field [0001] The invention relates to rice fields, fish ponds, and blister lakes Background technique [0002] At present, the eutrophication of rice fields, fish ponds, and blister lakes across the country is becoming more and more serious. In the high temperature season, a large amount of algae is produced, which directly threatens planting, breeding, and people's self-cultivation. In the rice field, due to long-term farming, nutrients are accumulated all year round, coupled with the application of fertilizers in the current season, the rice field is eutrophic, and in high temperature seasons, a large number of algae are produced, which increases the pH value of the water surface, resulting in alkaline rice fields. It is becoming more and more serious, causing harm to the rice field. The existing method of eliminating algae is to use copper sulfate or herbicides, which will cause excessive copper ions and plant poisoning after use. Contents of the invention ...
