摘要： 采用预沉—混凝—高效水力循环澄清—重力无阀过滤—消毒工艺，对井下废水进行处理。废水水量为6000m3?d-1，水质为COD100～270 mg?L-1，油类1.0～20 mg?L-1，SS60～1500mg?L-1。从运行情况和监测结果来看，出水水质稳定，符合设计要求以及《煤炭工业污染物排放标准》（GB 20426-2006）中的一级排放标准。

Abstract: The application of pre-precipitation—coagulation—efficient water cycle clarify—valveless gravity filter—disinfection process in treatment of coal mine wastewater was introduced. It was showed that when the influent water quality of mine wastewater were 6000m3?d-1, COD100～270mg?L-1, Oil 1.0～20mg?L-1, SS 60～1500mg?L-1. From the results of operation and monitoring, the quality of effluent was stability, and met the design requirements and the standard of class 1 in Coal Industry Discharge Standard of GB 20426-2006.
Key words: efficient water cycle clarify, valveless gravity filter, coal mine wastewater
