| titleOfInvention | A kind of coal washing wastewater treatment agent, its preparation method and application |
| abstract | The invention belongs to the technical field of coal chemical industry, and in particular relates to a treatment agent for coal washing wastewater, its preparation method and application. The coal washing wastewater treatment agent of the present invention includes modified molecular sieve powder, polyacrylamide, natural polymer flocculant, surfactant and hydrogen peroxide; the modified molecular sieve powder is composed of molecular sieve powder and calcium oxide, and its pores contain oxidation Calcium; the natural polymer flocculant is selected from cationic starch derivative flocculant, anionic starch derivative flocculant, amphoteric starch derivative flocculant, cationic lignin flocculant, anionic lignin flocculant or Several combinations. The coal washing wastewater treatment agent of the present invention is used in combination with polyacrylamide, natural polymer flocculant and modified molecular sieve powder, which reduces the amount of polyacrylamide, does not introduce additional metal ions such as iron and aluminum, and has excellent water Purifying effect. |
