摘要
使用DR058型树脂对焦化废水进行脱附有机物预处理后,再使用DR022型树脂脱附氨氮。使废水中氨氮脱附效率提高3.2%,达到99.30%,提高树脂穿透点吸附量62.7%,达63.24mg/g,并可提高吸附速率66.7%。试验表明除去焦化废水中多种有机物后,树脂对废水中氨氮的脱附能力将显著提高。
The adsorption by using DR022 resin ammonia nitrogen in coking wastewater after pretreatment by DR058 resin could increase ammonia nitrogen in wastewater stripping efficiency by3.2%,up to 99.30%.Improve the resin through adsorption quantity 62.7%,up to 63.24mg/g,and can improve the adsorption rate of 66.7%.After removal of a variety of organic compounds in coking wastewater,tests showed that the resin of ammonia nitrogen in waste water stripping ability will be improved significantly.
