| titleOfInvention | A sewage treatment process and equipment for high-concentration dyeing and judging |
| abstract | The invention discloses a sewage treatment process for high-concentration dyeing and color judging. In step 1, sewage is put into a stirring tank, and chemicals are added into the stirring tank. The chemicals are polyaluminum chloride and polyferric chloride, and stirring for 2-3 After 2 hours, the precipitate and the supernatant are obtained, the precipitate is transported to the filter press by the pump, the supernatant is sent to the chemical tank, step 2, the chemical is added to the chemical tank, the chemical is polyacrylamide and a decolorizing agent, and the precipitate is obtained and the supernatant, the supernatant is sent to the coagulation sedimentation tank, step 3, the COD agent is put into the coagulation sedimentation tank, and the filtrate is sent to the filter tank, step 4, the filter tank further filters the colored molecules. The process equipment of the invention is simple in operation, stable in operation, small in floor space, precipitates the suspended solids and colored substances in the sewage through chemical treatment and physical treatment, does not cause secondary pollution, and effectively treats the high-concentration dyeing and color-judging sewage in the sewage. COD and chromaticity, the water quality of the filtered water meets the discharge standard and can be used for factory production water. |
