摘要
硫醇甲基锡生产过程中产生的缩合废水,含有大量有机锡、氨氮、有机硫化物及盐类等污染物,属于高COD、高含盐量、有毒、难降解有机废水。针对此种废水的特点,在实验室研究基础上,确定采用絮凝气浮/加酸蒸发/加碱吹脱/铁炭微电解/絮凝沉淀/生物蠕动床处理工艺。实际工程运行结果表明,对于COD为6 316～12 030 mg/L、氨氮为30 632～39 700 mg/L、氯化铵为102 300～117 600 mg/L、总锡为193.4～201.7 mg/L、总硫为1 276～1 578 mg/L的原水,处理后出水水质可以达到《污水排入城市下水道水质标准》(CJ 3082—1999)。
The condensate wastewater produced in the production of methyhin mercaptide contains a lot of organotin, ammonia nitrogen, organic sulfides, salts and so on, which is a kind of organic wastewater with high COD, high salinity, toxicity and hard degradation. According to the characteristics of the wastewater, based on laboratory studies, the combined process of flocculation air-floatation, acidi- fication evaporation, alkanization stripping, ferric-carbon microelectrolysis, flocculation sedimentation and biological peristalsis bed was determined to be used. The actual project results show that the raw wastewater with COD of 6 316 to 12 030 mg/L, ammonia nitrogen of 30 632 to 39 700 mg/L, ammonium chloride of 102 300 to 117 600 mg/L, total tin of 193.4 to 201.7 mg/L and total sulfur of 1 276 to 1 578 mg/L can be treated to meet the Discharge Standard for Municipal Wastewater （CJ 3082 -1999）.
