Pond-lake heavy-metal pesticide fertilizer pollutant solidifying removing agent and preparation method thereof

Abstract

A pond-lake heavy-metal pesticide fertilizer pollutant solidifying removing agent relates to the technical field of disinfectants, and is composed of the following raw materials: 450-600 parts of montmorillonite, 150-300 parts of silicate clinker, 80-150 parts of quicklime, 50-100 parts of modified starch, 10-30 parts of plaster, 3-6 parts of glucoside, 5-10 parts of alum, and 3-8 parts of calcium chloride. The beneficial effects comprise that the employed raw materials are abundant and cheap, the preparation technology is simple, the agent is applicable to pollution cleaning of large-scope water body of ponds, lakes and rivers, is capable of rapidly thoroughly eliminating organic harmful substances, chemical pesticides and harmful microbes and heavy metals in water body, has improving eliminating effect on total phosphorus and total nitrogen in eutrophic water, has growth-controlling effect on algae in water body, and has water-bottom anti-permeation effect and effect of preventing heavy metals from permeating and polluting water resource.

Description

technical field [0001] The invention relates to the technical field of disinfectant preparation, in particular to a curing and eliminating agent for heavy metal pesticide and fertilizer pollution in ditches, ponds and lakes and a preparation method thereof. Background technique [0002] Without water, there will be no life, and there will be no human beings. However, with the increase of the social population, the demand for life is increasing, and the emissions are also increasing. Therefore, people need food for life, and food production requires pesticides and chemical fertilizers. A large number of chemical fertilizers and pesticides are used to increase production and harvest. Excessive use of chemical fertilizers and pesticides causes water pollution. Toxic and harmful substances such as arsenic, cadmium, and cyanide in pesticides flow into ditches, ponds, dams, and rivers and lakes when it rains. , pollute water resources, make green water smelly, cause fish and shrim...

AI Technical Summary

Problems solved by technology

[0003] In view of the fact that most of the existing water purifiers are made of chemicals, or use inorganic acids, alkalis or chlorides to purify water, although such water purifiers can eliminate and kill toxic substances in the water. Harmful substances purify the water body, but at the same time of sterilization and disinfection, its own toxic organic components remain in the water body, thereby increasing the organic components in the water body, making it difficult for the water body to obtain ideal purification standards

Although there are also existing water purifiers that have adopted the mineral powder of adsorption properties to make, such as palygorskite, zeolite, diatomaceous earth, vermiculite, sepiolite, medical stone, etc. to make water pollution adsorbents, but The disadvantage is that the production process is complicated, it needs calcination, acid activation and other cumbersome processes, and the cost is high. It can only be used in small batches of drinking water. The adsorbed pollutants cannot be solidified, and there will be secondary activity to cause re-pollution
