Problems solved by technology

At present, the fiber materials used for heavy metal adsorption are mainly materials containing multifunctional groups such as hydroxyl and amino groups, such as cellulose, polyacrylonitrile, and polyimide; and for traditional fiber materials, due to their preparation process through Spinning and then weaving to prepare membranes or fabrics can be applied to the treatment of heavy metals in water bodies. The spinning and weaving process is complicated and there are many processes

Abstract

The invention relates to mesh cloth for sewage treatment. The mesh cloth for sewage treatment is characterized in that the mesh cloth is prepared through three-dimensional knitting by a warp knitting machine and has the thickness of 10-50 mm, the permeable capacity larger than 1,800 mm*s<-1> and the bursting strength larger than 2,000 N. With the adoption of the structure of the mesh cloth, in the process of sewage treatment, warp in the vertical direction can be well contacted with heavy metals in sewage, and the problem that the adsorbing effect is weakened due to the fact that the contact surface of traditional fabric with the sewage is reduced due to the overlapped structure is solved.

Description

technical field [0001] The invention relates to the technical field of sewage production, in particular to a mesh cloth for sewage treatment and a preparation method thereof. Background technique [0002] With the continuous progress of society and the rapid development of industry, the pollution caused by the discharge of heavy metal wastewater has posed a serious threat to the ecosystem and public health. Heavy metals in water have become one of the most serious environmental problems in my country. Therefore, heavy metal wastewater Governance has been highly valued by researchers at home and abroad. In order to more effectively prevent and control heavy metal pollution in water bodies, our country has introduced a number of legal systems for the treatment of heavy metals in water. At present, the treatment methods of heavy metal wastewater mainly include chemical precipitation, ion exchange, solvent extraction, chemical redox and adsorption methods, etc. Among them, the a...
