Abstract

The invention discloses a glyphosate-polluted sludge treatment agent and a preparation method. The glyphosate-polluted sludge treatment agent is prepared from the following major raw materials in parts by weight: 20-30 parts of nano-modified sludge, 8-10 parts of bamboo charcoal, 22-30 parts of polyethylene glycol p-isooctyl phenyl ether, 10-16 parts of polyacrylamide, 10-15 parts of triton, 3-5 parts of carrageenan, 0.2-0.4 part of sodium metasilicate and 0.2-0.4 part of apatite. By adopting the glyphosate-polluted sludge treatment agent, the physicochemical index of soil severely polluted by glyphosate can reach the GB15618-2008 standard; the treatment agent is simple in process, is small in dosage, and has a good treatment effect, stable performance, very high economic benefit and wide social benefit, the recovery degree of the polluted soil is high, and the cost of the sludge treatment agent can be reduced effectively.

Description

technical field [0001] The invention relates to the technical field of sludge, in particular to a glyphosate 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 ha...
