Research on Comprehensive Wastewater Treatment and Recycling Technology in Coal Mines
In order to improve the efficiency of coal mine wastewater treatment,taking a coal mine as an example,a comprehensive wastewater treatment and recycling technology for coal mines is introduced.Firstly,the basic situation of a certain coal mine was briefly introduced.Based on this,the optimal process parameters for wastewater treatment were determined through coagulation and biochemical experiments.Through research,it is known that when treating coal mine comprehensive wastewater,with a pH value of around 8.0,a coagulant dosage of around 100 mg/L,and a PAM dosage of around 0.2 mg/L,the best effect is achieved for continuous treatment of coal mine wastewater for 3 days.The CODcr removal rate can reach over 80%,and the required cost is relatively low.Therefore,this technology can be promoted to the modern coal mining field.
