A HIGH EFFICIENCY PURIFYING METHOD FOR RECYCLING COAL SLURRY WATER

摘要

A high efficiency purifying method for recycling coal slurry water is applied to coal slurry water in coal washery. Adding modifier to improve the water hardness purifies the coal slurry water. A hardometer is used to defect the water hardness. When the defected result is lower than the critical value, the water quality modifier is added into the coal slurry water after calculating the adding quantity of the water quality modifier. The present invention uses the cheap, nonpolluting water quality modifier to adjust the water hardness and accelerate the settlement of the solid particle. The coal slurry water is purified and recycled.
