【Abstract】 Coal dressing wastewater of high suspended solids in difficult to naturally precipitate and filter. New method is set up with deals with the coal dressing wastewater by using carbide ash and polyacrylamide together. This method is simple and has better treatment results and lower agent cost.Treated with chemicals the sludge filtration resistance was decreased and the coal dressing wastewater can be easily dewatered mechanically.更多还原
