UASB_曝气沉淀_IC反应器处理高浓度硫酸盐有机废水_王白杨UASB/曝气沉淀/IC反应器处理高浓度硫酸盐有机废水王白杨,王正辉,张卓,侯正,王会平(南昌大学环境科学与工程学院,江西南昌330031)摘要:在赤霉素生产过程中产生的高浓度硫酸盐有机废水,处理难度较大。采用UASB/曝气沉淀/IC反应器工艺处理该废水,UASB中的硫酸盐还原菌将硫酸根还原为硫化物,曝气池中的脱硫杆菌则将硫化物氧化为单质硫,并在沉淀池中去除,IC反应器去除COD。系统稳定运行后,对硫酸盐的去除率>90%,对COD的去除率>80%。关键词:赤霉素生产废水;高浓度硫酸盐;UASB;IC;硫酸盐还原菌;产甲烷菌中图分类号:X703.1文献标识码:C文章编号:1000-4602(2008)20-0054-04TreatmentofOrganicWastewaterwithHighConcentrationSulfatebyUASB/AerationSedimentation/ICReactorWANGBai-yang,WANGZheng-hui,ZHANGZhuo,HOUZheng,WANGHui-ping(CollegeofEnvironmentalScienceandEngineering,NanchangUniversity,Nanchang330031,China)Abstract:Itisdifficulttotreatorganicwastewaterwithhighconcentrationsulfateproducedduringproductionofgibberellin.Therefore,UASB/aerationsedimentation/ICreactorareusedtotreatthiswastewater.Thesulfate-reducingbacteriareducesulfateradicaltosulfideinUASB,thedesulfobacteriaoxidizethesulfidetoelementalsulfurinaerationtank,theelementalsulfurisremovedinsedimentationtank,andCODisremovedinUASB.Afterthestableoperationofthesyste
