Problems solved by technology

Ordinary chemical remediation has the advantages of short repair period and fast repair effect. However, due to its high cost, it is easy to cause secondary pollution of the soil
Dieldrin, formula C 12 h 8 Cl 60 , as a highly efficient organochlorine pesticide, is commonly used in countries all over the world, but because it is an environmental hormone pollutant, it has harmful and toxic substances that interfere with the endocrine of humans and other animals, and it is very easy to persist in the soil; It is a very urgent task to treat and remediate admixture-contaminated sludge

Abstract

The invention discloses a dieldrin-polluted sludge treatment agent and a preparation method thereof. The dieldrin-polluted sludge treatment agent is prepared from the following main raw materials in parts by weight: 24 to 28 parts of nanometer modified sludge, 5 to 10 parts of pebble, 14 to 20 parts of polyoxyethylene methyl glucoside ether, 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 aluminum oxide, and 0.2 to 0.4 part of potassium chloride. The dieldrin-polluted sludge treatment agent has the advantages that the physicochemical index of the soil seriously polluted by dieldrin can reach the GB15618-2008 standard; the treatment technology is simple, the usage amount is less, the treatment effect is good, the property is stable, the restoration degree of polluted soil is high, the cost of sludge treating agent is effectively reduced, and the good economic benefits and wide social benefits are realized.

Description

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