蒸发浓缩_SBR联合处理高盐度高浓度医药中间体废水蒸发浓缩-SBR联合处理高盐度高浓度医药中间体废水*孔峰1张晓叶2(11江苏技术师范学院环境工程系,江苏常州213001;21常州化工研究所有限公司,江苏常州213001)摘要:针对高盐度高浓度有机废水,提出了蒸发浓缩-SBR联合处理新技术。采用减压蒸发浓缩有机废水,对浓缩液中的硫酸钠进行结晶回收,回收后的硫酸钠结晶物可以作为半成品销售,浓缩残渣液进行焚烧处理;蒸发冷凝水再经SBR生化处理达标排入污水厂。该技术可有效处理高盐分高浓度有机废水,经济合理,并可实现资源综合利用。关键词:蒸发浓缩;SBR;高盐分;高浓度;医药中间体THETREATMENTOFMEDICALWASTEWATERWITHHIGHSALINITYANDHIGHORGANICCONTENTSBYEVAPORATION-SBRKongFeng1ZhangXiaoye2(11EnvironmentalEngineeringDepartment,TechnicalNormalSchoolinJiangsu,Changzhou213001,China;2.ChangzhouChemicalInstituteCo.,Ltd.,Changzhou213001,China)Abstract:Inaccordancewiththecharacteristicsofhighsalinityandhighorganiccontentsofthewastewaterfromachemicalplant,putforwardisanewtreatmenttechniquebasedonevaporation-condensedandconcentrationfollowedbySBRbiochemistrytechniques.Theorganicwastewaterisconcentratedbymeansofvacuumevaporation-condensed,andthesodiumsulfatecrystalisrecoveredandissoldassem-imanufacturedgoods.Therestoredconcentrateissubjecttoincinerationwhilethecondensatewateristreatedaerobic
