A/SBR工艺处理煤制乙二醇污水的研究

Study on Treatment of Coal-made Ethylene Glycol Wastewater by A/SBR Process

针对煤制乙二醇产生污水的问题,对比了A/SBR法和A^2/O法,结果表明:A/SBR法具有投资省、设备少、占地少、维护运行费用低、出水水质好、耐冲击等优点。本项目采用A/SBR组合工艺,进水COD为1 000mg/L,出水水质COD≤50mg/L,氨氮由110mg/L降至5.0mg/L,达到了GB 18918-2002《城镇污水处理厂污染物排放标准》中的一级A标准。

Based on the problem of wastewater produced by coal-made ethylene glycol, this essay compares the A/SBR method with A2/O method. The result presents that A/SBR method has the advantages such as low investment, less equipment, less land occupation, low maintenance cost,good water quality and excellent impact resistance and so on. The project adopts A/SBR combination process, with incoming water COD of 1000mg/L, outcoming water COD≤50mg/L, ammonia nitrogen concentration decreasing from 110mg/L to 5. 0mg/L, which reaches A level regulated in GB18918- 2002 ＂Urban Sewage Treatment Plant Sewage Discharge Standards＂.
