摘　　要：通过对环丁砜法脱除天然气中硫生产工艺中产生的废水的试验研究表明，采用生物水解酸化好氧生物处理工艺较适宜。当进水ＣＯＤＣｒ和ＢＯＤ５浓度分别为４６５ｍｇ／Ｌ和１９５ｍｇ／Ｌ，水解酸化停留时间１２ｈ，好氧生物接触氧化塔停留时间５ｈ时，连续动态试验出水ＣＯＤＣｒ和ＢＯＤ５分别为４２ｍｇ／Ｌ和１６ｍｇ／Ｌ，ＣＯＤＣｒ和ＢＯＤ５的去除率分别达９１％和９２％The treatment methods of the wastewater from natural gas desulfurization by sulfolane process were studied.The results show that the hydrolytic acidification\|aerobic biological process is more suitable for treating the wastewater.When the CODCr and BOD5 in the influent were 465mg/L and 195mg/L,respectively,the resident time in the hydrolgtic acidfication step was 12h.the resident time in the biologocal contact oxidation step was 5h,the CODCr of 42mg/L and the BOD5 of 16mg/L in the effluent of this system can be observed and the removal rates of CODCr and BOD5 were up to 91% and 92%,respectively.
