Abstract

The invention discloses a formaldehyde-contaminated sludge treatment agent and a preparation method thereof. The formaldehyde-contaminated sludge treatment agent is prepared from the following raw materials in parts by weight: 15-30 parts of aluminum oxide, 8-14 parts of dibutyl maleate, 4-8 parts of mollugin, 5-10 parts of sodium alkyl benzene sulfonate, 10-15 parts of bamboo vinegar powder, 3-5 parts of capryloyl salicylic acid, 4-11 parts of phosphorous gypsum, 5-12 parts of betel nut powder, 4-8 parts of disodium ethylenediamine tetraacetate, 1-3 parts of tea tree oil, 2-8 parts of cocamidopropyl betaine, 0.1-1 part of an emulsifying agent, 2-4 parts of shell powder, 2-5 parts of cattle bone powder, 0.5-1 part of tea polyphenol, 3-7 parts of toona sinensis leaf powder, 1-4 parts of zeolite powder and 1-3 parts of nano silver. The formaldehyde-contaminated sludge treatment agent provided by the invention has a remarkable treatment effect, is less in consumption during treatment and good in treatment effect, and has the formaldehyde fixation rate of more than 94%.

Description

Technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a formaldehyde polluted sludge treatment agent and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy, the number of automobiles has risen sharply, and gas stations and underground storage tanks are scattered everywhere and the number is increasing day by day. However, due to poor design and management, most of these oil storage tanks did not fully consider the strength of the tank and the corresponding leakage protection measures when buried. 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 pollution of the soil by petroleum and chemical industries, especially the pollution caused by a large amount of volatile organic compounds (VOCs), has attracted more and more attenti...
