Heavy metal wastewater adsorbing material and preparation method thereof

Abstract

The invention discloses a heavy metal wastewater adsorbing material and a preparation method thereof. The heavy metal wastewater adsorbing material is characterized by being prepared from the following ingredients by weight parts: 4-6 parts of rectorite, 3-7 parts of kaolinite, 2-5 parts of polyacrylamide, 1-3 parts of aluminum sulfate, 1-2 parts of carboxymethyl chitosan, 1-2 parts of deacetylated chitin, 5-10 parts of ferric chloride, 5-10 parts of ammonia water, 1-2 parts of phosphatidylinositol, 2-4 parts of methyl parahydroxybenzoats, 0.2-0.6 part of sodium diacetate, 0.4-0.8 part of hydrogen peroxide, 0.1-0.6 part of peroxyacetic acid, 1-2 parts of sodium laurylsulfate, 80-100 parts of sodium hydroxide, 10-20 parts of ethylene glycol, 80-100 parts of ethyl alcohol, 0.1-0.2 part of sodium hydrosulfite, 70-100 parts of hydrochloric acid and 100-200 parts of water.

Description

technical field

[0001] The invention relates to the field of sewage treatment, in particular to a heavy metal wastewater adsorption material and a preparation method thereof. Background technique

[0002] The cost of the rapid development of modern industry and the continuous improvement of people's living standards is the massive pollution of the environment, among which the pollution of water resources has become a serious problem that needs to be solved urgently. Due to the excessive growth of population and the rapid development of industrialization, China has become a country seriously short of water. At the same time, water pollution is also increasing, which further causes the shortage of water resources in our country. Water pollution mainly includes industrial wastewater, agricultural wastewater and domestic wastewater, among which the pollution of industrial wastewater is the most serious. Industrial wastewater often contains pollutants such as refractory organic ...
