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 ...
