| Message: | coal washing waste water clarifying agent of cationic polyacrylamide CPAMWater purification of flocculation Boyuan lab experimental study on the treatment of coal washing wastewater did thousands of experiments, have rich experience in coal washing industry. In general, coal washing wastewater of high quantity, high chroma, high pollution. Laboratory experiments on respectively Boyuan ratio of anionic, nonionic, cationic polyacrylamide flocculant of three kinds of organic wastewater treatment, compare the effect are not very ideal. The personnel and the inorganic flocculant with these three kinds of organic polymer flocculant was found that the effect is very good; less amount of organic polymer flocculant, flocculation time is short, alum and solid, fast sedimentation. Through the experiment, it is concluded that the suitable flocculation conditions: 100 mL wastewater with the dosage of 0.001 g, sodium sulfate is 0.06 g, pH is 9.7, the mixing time is 20 min. Under this condition, the removal rate of COD reached 80.5% jianchang. The chroma removal rate of wastewater was 92.9%. Can fully meet the coal washing wastewater. As the coal washing waste water clarifying agent using polyacrylamide on the reduction, the operation cost is greatly reduced. url:http://www.boyuanpam.com |
