煤矿矿井水处理与资源化

摘要

根据煤矿矿井水的水质特点,将煤矿矿井水分为中性矿井水和酸性矿井水,并指出了中性矿井水和酸性矿井水的水质污染特点.提出了中性矿井水采用:调节+混凝沉淀+多介质过滤+精密过滤+膜处理+消毒的联合处理工艺,使处理后的矿井水能够达到生活饮用水卫生标准.介绍了确定工艺中的有关参数的方法和应考虑的因素.为矿井水的污染治理与回用提供了一个经济可行的技术方案.%Coal mine water is classified into neutral and acid mine water according to the water quality and points out the pollution characteristics of the neutral and pointsout acid mine water. The combining process of regulating + coagulating sedimentation + mulit-media fliter + ultrafilter+membrane treatment+disinfection is proposed to treat neutral mine water. After treatment, the effluent can meet the hygienic standard for domestic drinking water. Introduces the method to determine the parameters of the process and the factors to be considered. It has put forward an economically feasible technical program for mine water treatment and reclamation.
