小回沟煤矿矿井水处理站设计

Design of mine waste water treatment station in Xiaohuigou Coal Mine

结合小回沟煤矿矿井水来源及水质特点,分析了矿井水处理站的设计范围和设计规模,研究了改进型混凝沉淀过滤消毒的处理工艺和设备,即"旋流混凝澄清+机械过滤器+消毒",从预沉调节池、旋流混凝澄清净水装置、机械过滤器和清水池等方面进行了工艺设计,从主要建(构)筑物、水处理设备、加药设备、污泥处置、生产废水处置和供电控制系统等方面进行了单元设计。经试运行期间调试结果表明,小回沟煤矿矿井水处理工艺成熟可靠,操作简单,便于管理维护,出水水质达到了预定目标。

Combining with the mine water source and quality in Xiaohuigou Coal Mine,the paper analyzes the design range and scale of the mine waste water treatment station,studies the underground drainage treatment technology,including processes of swirl coagulation clarification,mechanical filter and disinfect; and then designs the process from the pre-settling regulating tank,swirl coagulation clarifier,mechanical filter and clean-water reservoir; and designs the units from buildings/structures,water treatment equipment,dosing equipment,sludge disposal,waste water disposal and power supply control system.The test results show that the Xiaohuigou coal mine water treatment technology is mature and reliable,easy to operate,manage and maintain,and the treated water quality has reached predetermined target.
