Abstract

The high efficiency nanometer water purificant consists of polyacrylamide, nanometer active carbon, etc. It includes two components, the component A comprising polyacrylamide 80-98 % and soluble chitosan 2-20 %, and the component B comprising nanometer active carbon 80-90 %; nanometer TiO2 1-3 % and polyacrylamide 9-17 %. The present invention is one new kind of water treating preparation with high neutralizing, bridging, permeating and adsorbing capacity, high sewage purifying effect, fast sewage purifying speed and small consumption.

Description

technical field [0001] The invention relates to the field of purification and treatment of various industrial and domestic sewage. technical background [0002] Sustained and rapid economic development is facing the challenge of major environmental pollution. Water pollution is a serious environmental problem. At present, the reduction of water resources has become an important factor restricting economic development. Reasonable water use and effective treatment of sewage have far-reaching significance for the protection of water resources. [0003] The purification of industrial and domestic sewage requires the use of comprehensive technologies such as physics, chemistry, biochemistry, and electrolysis, among which the use of water treatment chemicals and activated carbon accounts for a considerable proportion. [0004] The purification treatment of industrial and domestic sewage often adopts the addition of water treatment chemicals and flocculation technology. This is a...
