Abstract

The invention discloses a treatment agent of sludge polluted by vinyl chloride and a preparation method of the treatment agent. The treatment agent of the sludge polluted by t he vinyl chloride is prepared from the following main raw materials in parts by weight: 25-30 parts of nano modified sludge, 15-20 parts of cobblestone, 15-25 parts of cyclodextrin, 8-12 parts of polyacrylamide, 4-8 parts of hydroxyacetic acid, 2-6 parts of polyether modified silicone oil, 0.2-0.4 part of aluminum oxide and 0.2-0.4 part of potassium chloride. According to the treatment agent of the sludge polluted by the vinyl chloride, physical and chemical indexes of the soil which is severely polluted by the vinyl chloride can meet the GB15618-2008 standard; the treatment process is simple; the chemical consumption is low; the treatment effect is good; the performance is stable; the polluted soil is high in restoration degree; the cost of the sludge treatment agent can be effectively reduced; the treatment agent has excellent economic benefits and broad social benefits.

Description

technical field [0001] The invention relates to the technical field of sludge, in particular to a treatment agent for vinyl chloride polluted sludge and a preparation method thereof. Background technique [0002] With the rapid development of our country's economy, the number of cars has risen sharply, and gas stations and underground oil storage tanks are dotted all over the country and the number is increasing day by day. However, due to poor design management, most of these oil storage tanks were buried without fully considering the strength of the tank body and the corresponding leakage protection measures. Once leaked, it will cause serious pollution to the surrounding soil and groundwater. Especially with the aging of oil storage tanks, this problem will become more prominent. For this reason, the soil pollution caused by petroleum and chemical industries, especially the soil pollution caused by a large amount of volatile organic compounds (Volatile Organic Compounds,...
