BSBR工艺研究范金霞(临沂市数字化城市管理中心,山东临沂276004)摘要:采用BSBR法对农药废水的处理进行了研究,确定了其最佳工艺条件,并分析了曝气时间、曝气强度、进水浓度及pH对有机物去除率的影响。BSBR法和SBR法的对比实验表明:BSBR处理效果明显好于普通SBR法。BSBR法对有机物降解速率快,污泥量少,去除率高。同时在最佳工艺条件下,对医药废水和印染废水处理效果好。关键词:BSBR;农药废水;COD去除率中图分类号:X703.1文献标识码:B文章编号:1005-8206(2009)S1-0017-04StudyonBSBRProcessFanJinxia(LinyiDigitalUrbanManagementCenter,LinyiShandong276004)Abstract:PesticidewastewatertreatmentusingBSBRprocesswasresearched.Thebestprocessconditionwasdetermined,andeffectsofaerationperiod,aerationintensity,influentconcentrationandpHvalueonremovalrateoforganicmatterwereanalyzed.ContracttestofSBRwithBSBRshowedthattreatmenteffectofBSBRisbetterthanthatofcommonSBR.BSBRhassomeadvantages,suchasrapidorganic-matterdegradation,smallamountofsludgeandhighremovalrate.BSBRhadbettertreatmenteffectofmedicalwastewateranddyewastewateronthebestprocesscondition.Keywords:sequencingbatchbioreactor;pesticidewastewater;removalrateofCOD收稿日期:2009-02-23SBR法(SequencingBatchReactor),即序列间歇式活性污泥法,根据SBR的运行时间次序,把整个运行过程分为充水阶段、反应(曝气)阶段、沉淀
