混凝澄清+超滤反渗透工艺处理天池煤矿矿井水

COAGULATION AND CLARIFICATION +ULTRAFILTRATION AND REVERSE OSMOSIS PROCESS TO TREAT MINE DRAINAGE WATER IN IANCHI COAL MINE

为了提高矿井水处理系统的处理能力和改善出水水质,天池煤矿对矿井水处理系统进行了改造升级。该工程的矿井水净化处理采用以混凝澄清为主的处理工艺,深度处理采用超滤和反渗透相结合的处理工艺,从而使净化处理后的出水全部达到排放标准,深度处理后出水全部达到生活饮用水标准。本文详细介绍了各系统的工艺选择、工艺流程、主要构筑物和主要设备,同时对经济效益进行了分析。运行实践表明,该工程所采用的工艺合理、运行稳定、自动化程度高、操作维修简单,具有一定的应用前景。

In order to improve processing capability and effluent quality of mine drainage water treatment system, the system has been upgraded in Tianchi coal mine. The process combined coagulation with clarification is adopted in the purification treatment subsystem, which ensures the purified water quality meeting the emission standards; and the process combined uhrafiltration with reverse osmosis is adopted in the advanced treatment subsystem, which guarantees the last effluent quality satisfying the drinking water standard. This paper detailedly introduces process choices and flow diagram, main facilities and equipments, and economic benefits. The operation practice shows that the engineering has many characteristics of reasonable process, stable operation,high degree of automation, simple operation and maintenance, and good application prospects.
