Abstract

The invention discloses a dichlorobenzidine polluted sludge treating agent and a preparation method thereof. The dichlorobenzidine polluted sludge treating agent comprises the following main raw materials in parts by weight: 20-30 parts of nano modified sludge, 10-20 parts of bamboo charcoal, 15-25 parts of vinyl triethoxy silane, 10-18 parts of polyacrylamide, 10-15 parts of diisocyanate, 3-5 parts of beeswax, 0.2-0.4 part of trihydroxymethyl aminomethane, and 0.2-0.4 part of apatite. The dichlorobenzidine polluted sludge treating agent disclosed by the invention can enable physical and chemical indexes of soil seriously polluted by dichlorobenzidine to reach a GB15618-2008 standard; and the treatment process is simple, the amount of the used agent is less, the treatment effect is good, the performance is stable, the restoration degree of the polluted soil is high, the cost of the sludge treating agent can be effectively reduced, and very good economic benefits and wide social benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of sludge, in particular to a dichlorobenzidine polluted sludge treatment agent and a preparation method thereof. Background technique [0002] Aromatic amines are contained in wastewater and wastes discharged from industries such as textiles, chemicals, and paper making, and a large amount of them entering the environment will pose a threat to human health. Long-term exposure to aromatic amines may cause headaches, nausea, fatigue, insomnia, vomiting, coughing and other adverse symptoms in mild cases, and severe diseases may lead to bladder cancer, ureteral cancer, kidney cancer and other malignant diseases, and the incubation period is as long as 20 years. The entry of aromatic amines into the soil will also cause harm to the soil ecological environment. Dichlorobenzidine (DCB) is an important intermediate of pigments, which is easy to deposit in soil and has a strong carcinogenic effect on the human body...
