[给水排水工程论文] 摘要: 以煤矿生产过程中产生的高悬浮物酸性矿井污水为实验对象,研究“重力沉淀——中和滤池——曝气——混凝——曝气”流程对污水处理的工艺,实验证明该工艺在中和酸性矿井污水的同时具有较高的SS(悬浮物)、Fe、Mn、SO42-去除效果。通过实验设计一体化处理设备应用于实践证明该工艺处理效果可达排放标准要求。 关键字: 悬浮物 酸性 煤矿污水 混凝 石灰石 滤池 Experimentation and application on sewage treatment about acidic colliery of suspended matter of having a very high content WANG Hai-feng, HUANG Bi-fang, ZHANG yuanfu (College of Material Science and Metallurgy Engineering, Guizhou University, Guiyang, Guizhou 550003,China) Abstract: The paper studies the art of sewage treatment about the flow on gravitational settling-counteracting filter cell-aeration-oagulate-aeration, as experimental subject with producing sewage about acidic mine of suspended matter of having a very high content in a colliery manufacturing process. Experimentation is proved that the art possesses the effect on wiping off upper SS (suspended matter)、Fe、Mn、SO42- in counteracting sewage of acidic mine process simultaneity. Application on all-in-one handling equipment via designing of experiment is testified that treatment effect of the art can achieve the demand on emission standard. Keyword: suspended matter; acidic; sewage of colliery; oagulate; limestone; filter ce……
