[0002] During the treatment of coking wastewater, a part of surplus sludge and chemical sludge will be generated. These sludges are processed by concentration and sludge dewatering equipment to obtain solid sludge with a water content of less than 80%. The dewatered sludge first enters the sludge storage tank, is loaded into the sludge storage hopper through the sludge discharge pipe, and then the sludge storage hopper is sent to the coal preparation workshop by a forklift. The sludge is poured into the coal blending mixer for coal blending. Coal blending is one of the processes for preparing coking coal for coking. Different types of raw coal are combined in an appropriate proportion to produce coke that meets the quality requirements.
