Abstract

The invention discloses a treating agent for propanil contaminated sludge and a preparation method of the treating agent. The treating agent for the propanil contaminated sludge comprises main raw materials in parts by weight as follows: 20-30 parts of nano-modified sludge, 5-10 parts of bamboo charcoal, 20-30 parts of peptidoglycan, 10-16 parts of polyacrylamide, 10-15 parts of dihydropyridine, 3-5 parts of carrageenan, 0.2-0.4 parts of sodium thiosulfate and 0.2-0.4 parts of apatite. With adoption of the treating agent, the physical and chemical indexes of soil seriously contaminated by propanil can meet the standard GB15618-2008; a treating process is simple, the use amount is small, the treating effect is good, the performance is stable, the restoration degree of the contaminated soil is high, the cost of the sludge treating agent can be reduced effectively, and the treating agent has very good economic benefit and wide social benefit.

Description

technical field [0001] The invention relates to the technical field of sludge, in particular to a propanil polluted sludge treatment agent and a preparation method thereof. Background technique [0002] The food loss caused by diseases, insects and weeds in global agriculture accounts for about half of the total annual food production. The use of organic pesticides can recover about 30% of the losses. At present, there are more than 1300 kinds of organic pesticides produced and used in the world, of which about 250 kinds are widely used. my country has entered the world's largest pesticide production country. In 1994, my country's pesticide production was 266,000 tons, accounting for about 1 / 10 of the world's total pesticide production. In a certain period of time in the future, organic pesticides will still be an important means to maintain, increase and maintain stable food growth; at the same time, the environmental pollution caused by the use of organic pesticides has ...
