Abstract

The invention discloses a carbon tetrachloride sludge treatment agent and a preparation method thereof. The carbon tetrachloride sludge treatment agent comprises the following components in parts by weight: 20-30 parts of modified saline-alkali soil, 12 parts of auxiliary agent ‑18 parts, 2‑6 parts of triethanolamine, 0.1‑0.2 parts of sodium lauryl sulfate. The invention can make the physical and chemical indicators of the sludge seriously polluted by carbon tetrachloride reach the GB15618-2008 standard; the treatment process is simple, the dosage is small, the treatment effect is good, the performance is stable, the recovery degree of the polluted sludge is high, and the sludge can be effectively reduced. It reduces the cost of sludge treatment agent and has good economic benefits and extensive social benefits.

Description

technical field [0001] The invention relates to the technical field of a sludge treatment agent, in particular to a carbon tetrachloride sludge treatment agent 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 sludge and groundwater. Especially with the aging of oil storage tanks, this problem will become more prominent. For this reason, the pollution of sludge in petroleum and chemical industries, especially the pollution caused by a large amount of volatile organic compounds (Volatile Organic Comp...
