摘要
本文采用吸附树脂NDA-99和脱氮剂DN-17分别去除煤气洗涤废水中的酚类物质和氨氮。结果表明,处理后的出水挥发酚质量浓度<5mg/L,去除率>98%,总酚质量浓度<70 mg/L,去除率>90%。氨氮质量浓度<15mg/L,去除率>98%,BOD5/COD为0.65。该处理工艺可回收粗酚和(NH4)2SO4,是一项具有环境效益和经济效益的技术。
In this paper, adsorption resin NDA-99 and denitrifier DN-17 are used to remove phenol and nitrogen from coal gasification washing wastewater respectively. After the wastewater being treated, the concentration of volatile phenol is below 5mg/L; removal rate is over 98%. Total concentration of phenols is less than 70mg/L, removal rate exceeds 90%. The concentration of NH3-N decreases to 15mg/L, removal rate is more than 98%. The value of BOD5/COD is 0.65. Furthermore, both crude phenols and (NH4)2SO4 can be recovered from the wastewater. This technology has both of environmental and economic benefits.
