How to reduce the system's wastewater discharge

Thread Content

Due to the requirements for energy conservation and emission reduction, efforts have been made to reduce wastewater discharge. The process is methanol production from coal water slurry. Can the washing water for the filter press, which is raw water, be replaced by something else? 2 The heat source for the ammonia stripping tower is steam entering the tower directly; can a heat exchanger be used as a substitute? 3 What is the theoretical minimum value for the flushing water used in vaporization instruments and the sealing water for pumps, and to what extent can it be reduced without affecting safe production? 4 Dump trucks; all the wash water on the ground has been replaced with graywater. 5 All production water that meets the rainwater discharge standards has been routed through this pipeline for rainwater discharge. 6 All coal grinding uses wastewater. A single factory has limited capabilities; I hope the other factories can offer you some advice. How can wastewater discharge be reduced? Currently, 150 cubic meters of coal slurry are fed per hour, resulting in 2,700 tons of wastewater being discharged daily.
