Abstract

The invention discloses an industrial wastewater purifying agent which is prepared from the following components in parts by weight: 5-12 parts of polyaluminum chloride, 3-7 parts of polyferric sulfate, 2-5 parts of magnesium chloride, 6-9 parts of polyacrylamide, 4-8 parts of sodium hypochlorite, 8-15 parts of calcium oxide, 4-6 parts of sulfur, 11-15 parts of silicon dioxide, 13-18 parts of surfactant, 7-10 parts of biological degerming agent and 80-90 parts of anhydrous ethanol. The wastewater purifying agent has the advantages of high flocculation effect, high removal rate for suspended substances and heavy metals and favorable biological sterilizing effect, lowers the hazard of secondary pollution, and is more environment-friendly.

Description

technical field [0001] The invention relates to an industrial waste water purification agent. Background technique [0002] With the progress of society and the development of modern technology, industrial pollution is becoming more and more serious, especially industrial wastewater pollution, which is quite difficult to control. The traditional method of water pollution control is to separate the pollutants in water through filtration and precipitation, but this kind The method cannot solve the root of the problem; in the subsequent development, some chemical reagents are used for sedimentation and separation in industrial sewage treatment. Although some effects have been achieved, the treatment efficiency is low. In addition, there are adsorption methods, which mainly use exchange adsorption, physical adsorption or chemical adsorption to adsorb pollutants from wastewater to adsorbents to achieve the purpose of removal. The adsorption effect is affected by factors such as ...
