Abstract

The invention discloses a treating agent for mirex-contaminated sludge and a preparation method thereof. The treating agent for mirex-contaminated sludge comprises the following main raw materials by weight: 24 to 28 parts of nanometer modified sludge, 5 to 10 parts of cobblestone, 14 to 20 parts of diethylene triamine pentacetic acid, 9 to 11 parts of polyacrylamide, 10 to 15 parts of decabrominated dipheny ethane, 3 to 5 parts of glass fiber, 0.2 to 0.4 part of heavy calcium carbonate and 0.2 to 0.4 part of potassium chloride. The treating agent allows the physical and chemical indexes of soil severely contaminated by mirex to reach standard GB15618-2008; and the treating agent is simple in treating process, small in usage amount, good in treatment effect, stable in performance, high in the restoration degree of contaminated soil and greatly reduced in cost, and has good economic benefits and social benefits.

Description

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