Abstract

The invention discloses a formaldehyde pollution sludge treating agent and a preparation method thereof. The formaldehyde pollution sludge treating agent is mainly prepared from the following main raw materials in parts by weight: 32-38% of nano modified sludge, 12-16 parts of cobblestone, 8-16 parts of dodecy dimethyl benzyl ammonium bromide, 8-12 parts of polyacrylamide, 4-8 parts of glycolic acid, 2-6 parts of phosphoric acid, 0.2-0.4 part of aluminium oxide and 0.2-0.4 part of potassium chloride. The formaldehyde pollution sludge treating agent is capable of enabling physicochemical indexes of soil severely contaminated by potassium chloride to achieve GB15618-2008 standards; the processing process is simple, the dosage is less, the processing effect is favorable, the performance is stable, contaminated soil is high in recovery degree, the cost of the sludge treating agent can be effectively reduced, and the formaldehyde pollution treating agent has favorable economic benefits and wide social benefits.

Description

technical field [0001] The invention relates to the technical field of sludge, in particular to a formaldehyde-polluted 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 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, VOCs)...
