煤矿废水污染物综合治理研究

Study on comprehensive treatment of coal mine wastewater pollutants

污染物治理可以促进煤矿生态环境的可持续发展,为了提高对污染物的吸附率,研究煤矿废水污染物综合治理方法。以A地区Q煤矿为研究对象,通过制备Fe_(3)O_(4)@SiO_(2)-MIP作为煤矿废水污染物治理的吸附剂,以煤矿废水污染物的吸附量作为煤矿废水污染物综合治理的指标,分析了pH值、初始浓度、吸附剂用量、吸附时间对煤矿废水污染物吸附量的影响。结果表明,当pH值为7、初始浓度为140 mg/L、材料用量为100 mg、吸附时间为6 h时,煤矿废水污染物的吸附量分别可以达到5.5、22.3、30.0、23.5 mg/g,对煤矿废水污染物具有更好的吸附效果,促进了煤矿生态环境的可持续发展。

Pollutant treatment can promote the sustainable development of coal mine ecological environment.In order to improve the adsorption rate of pollutants,the comprehensive treatment method of coal mine wastewater pollutants is studied.Taking Q Coal Mine in area A as the research object,through the preparation Fe_(3)O_(4)@SiO_(2)-MIP is used as the adsorbent for the treatment of coal mine wastewater pollutants,and the adsorption capacity of coal mine wastewater pollutants is used as the index for the comprehensive treatment of coal mine wastewater pollutants.The effects of pH value,initial concentration,amount of adsorbent and adsorption time on the adsorption capacity of coal mine wastewater pollutants are analyzed.The results showed that when the pH value is 7,the initial concentration is 140 mg/L,the material dosage is 100 mg and the adsorption time is 6 h,the adsorption capacity of coal mine wastewater pollutants can reach 5.5 mg/g,22.3 mg/g,30 mg/g and 23.5 mg/g respectively,which has better adsorption effect on coal mine wastewater pollutants and promotes the sustainable development of coal mine ecological environment.
