%X 针对含煤废水色度大、悬浮物浓度高的特点，采用电絮凝/离心沉淀器/多介质过滤器工艺处理含煤废水，介绍了处理工艺流程及工艺特点，给出了主要处理单元设计参数、项目投资及运行成本。工程运行结果表明，在原水SS ≤ 5000 mg/l、pH为6~9、色度 ≤ 500，处理后出水SS ≤ 20 mg/l、色度 ≤ 50，达到《污水综合排放标准》(GB8978-1996)一级标准，并回用至洗车台进行运煤车的清洗用水。<br />
In view of the characteristics of large chroma and high concentration of suspended solids in coal- containing wastewater, the process of electric flocculation/centrifugal precipitator/multi-media filter is adopted to treat coal-containing wastewater. The process flow and characteristics are intro-duced, and the design parameters of main treatment units, project investment and operation cost are given. The engineering operation results show that the raw water SS ≤ 5000 mg/L, pH 6~9, chroma ≤ 500, the treated effluent SS ≤ 20 mg/L, chroma ≤ 50, meet the “Comprehensive Sewage Discharge standard” (GB8978-1996) level 1 standard, and can be reused to the car wash for cleaning water of coal truck.
