Special polyacrylamide coal mine coal washery
Boyuan water purification lab experimental study of flocculation on the treatment of coal washing wastewater has done more than 1000 experiment,have rich experience in coal washing industry.Commonly,large quantity of coal washing wastewater, the color is big, the pollution is strong.Boyuan laboratory tests were carried out on three kinds of organic polymer polyacrylamide flocculant, which are anionic, nonionic and cationic,compare the effect of wastewater treatment,found are not very ideal.The experiment personnel also use the inorganic coagulant and the three kinds of organic polymer flocculant to compound use,founding the result is good;low dosage of organic polymer flocculant,short time of producing,alum big and real,fast settling.The appropriate flocculation conditions are obtained through experiments：100 mL wastewater with anionic polyacrylamide dosage of 0.001 g,sodium sulphate 0.06g,PH 9.7,mixing time was 20 min.COD removal rate reached 80.5% of wastewater from alkaline factory under this condition.The chroma removal rate of wastewater was 92.9%.Can fully meet the coal washing wastewater.As the polyacrylamide coal mine preparation plant using the reduction of delivery,greatly reduce operating costs.
