AI Technical Summary

Problems solved by technology

[0003] The existing organic pesticide degradation technology mainly includes the combination of alkali decomposition method and biochemical treatment method. The alkali decomposition method mainly uses alkali to decompose organic phosphorus to reduce biological toxicity for further biochemical treatment, but it needs to invest a large amount of alkali. In addition, a closed space is required to prevent the leakage of harmful gases produced by the reaction, and it is difficult for microorganisms to survive under strong alkaline conditions, and it is necessary to neutralize the remaining alkali, which is costly and requires a large processing space

Abstract

The invention relates to a water treatment agent for removing an organic pesticide in wastewater. The water treatment agent is prepared by compounding the following raw materials: alpha-humulene, calcium carboxymethylcellulose, 5,5-dimethylimidazolidine-2,4-diketone, 3,5,7-trihydroxy-4`-methoxyflavone, (3beta)-8,24-lanostadiene-3-alcohol, 4-(2,6,6-trimethyl-2-cyclooctene-1-yl)-3-butene-2-ketone, crosslinked polyvinyl pyrrolidone, alpha-furfural, alpha-methyl-4-(1-methyl ethyl)benzenepropanal, 1,2-dyhydroxyl-1,2,3-propanetriformic acid, ethyl myristate, distarch glycerol, and 7-hydroxyl-3,7-dimethyl-octanal. The water treatment agent is strong in complexing power with the organic pesticide, is fast in sedimentation speed of formed complex, has the removal rate up to 99 percent, is low in toxicity, is small in dosage, does not generate harm to a water body, is small in occupation area, and is low in treatment cost.

Description

technical field [0001] The invention relates to a water treatment agent for removing organic pesticides in water, belonging to the technical field of environmental protection. Background technique [0002] The application of organophosphorus pesticides such as trichlorfon will enter the surface water with surface runoff, causing water pollution. Pesticide residues in the soil are the main source of accumulation in crops, and also seep in with rainwater or irrigation water, polluting groundwater. Organophosphorus pesticides are highly toxic and have a certain residual level in the environment. It is easy to form conjugated residues and binding residues with biological activity in organisms, which pose a potential threat to human health or the ecological environment. Organophosphorus pesticides can inhibit the activity of cholinesterase, causing acetylcholine (a neurotransmitter) to accumulate in body tissues, causing a series of poisoning symptoms of certain neurological di...
