Abstract

The invention discloses a treatment agent for organic phosphorus contaminated soil. The treatment agent for the organic phosphorus contaminated soil comprises the following components: dry cow dung, pullulan, sodium caseinate, selenium-enriched capsicum stems, sodium tripolyphosphate, magnesium chloride, calcium sulfate crystal whiskers, desalinated sea sand, hydrated zinc borate, molybdenum disulfide, calcite, pineapple leaf powder, dry moss, and a silica sol. The treatment agent provided by the invention can effectively treat the organic phosphorus contaminated soil, and can obviously reducethe content of methyl parathion, phorate and methidathion in the soil; the preparation process is simple, production preparation is facilitated; and the use method is simple and not restricted by environmental conditions, and has better social value.

Description

technical field [0001] The invention relates to a soil treatment agent, in particular to an organic phosphorus polluted soil treatment agent and a preparation method thereof. Background technique [0002] Because organophosphorus pesticides are not easy to oxidize, decompose, and be degraded by microorganisms, they can stay in the environment for a long time and may undergo chemical changes to become more toxic and harmful secondary pollutants. At the same time, the components remaining in plants can be enriched through the food chain, so that the amount of pesticide residues in food exceeds the hygienic standard. Organophosphorus pesticides can enter the human body through the digestive tract, respiratory tract and intact skin and mucous membranes. Occupational pesticide poisoning is mainly caused by skin pollution. Absorbed organophosphorus pesticides are distributed in various organs in the body, among which the liver has the largest content, and the content in the brai...
