Abstract

A modified active carbon waste water flocculant is composed of following raw materials in parts by weight: 100 to 120 parts of active carbon, 10 to 12 parts of acrylic acid, 3 to 4 parts of acrylamide, 10 to 12 parts of methacryloxyethyltrimethyl ammonium chloride, 10 to 12 parts of calcined gypsum, 5 to 6 parts of dried alum, 8 to 10 parts of modified attapulgite, 1 to 2 parts of silane coupling agent KH-550, and a right amount of water. The preparation method uses acrylic acid, acrylamide, and methacryloxyethyltrimethyl ammonium chloride to modify the active carbon, so the modified active carbon has a better flocculation effect on pollutants in water; adds calcined gypsum and dried alum into the flocculant to enable the flocculant to have an antibiotic effect, the preparation method adds the silane coupling agent KH-550 into the flocculant to strengthen the intensity of the flocculant to make the flocculant difficult to disintegrate.

Description

technical field [0001] The invention relates to a method for modifying non-metallic ore, in particular to a modified activated carbon wastewater flocculant and a preparation method thereof. Background technique [0002] With the development of science and technology and the gradual construction of modern industries, various chemicals have been developed and utilized, which has brought convenience to people's lives. The problem. [0003] At present, the pollutants in the air are mainly the gas produced by industrial fuel combustion, automobile exhaust, and toxic and harmful gases produced in production. Water pollution is mainly due to the fact that the sewage discharged from industrial production contains a large amount of toxic substances, and the sewage produced in people's daily life produces many harmful substances. There are many times in people’s lives that people need to remove toxins. For example, there are many bacteria and toxins on the filter screen of air condi...
