SBR法处理屠宰废水的工程应用_何健洪

SBR法处理屠宰废水的工程应用何健洪(中山市小榄镇环境保护管理所,广东中山　528415)　　[摘要]介绍了采用序批式活性污泥(SBR)法处理屠宰废水的工程实例。本实例主要用于中小型的屠宰废水中,主要建筑物有隔油隔渣池、调节厌氧池、SRR反应池。该核心工艺是SBR,其运行周期主要分为进水期、反应期、沉淀期、排水期和闲置期等五个阶段。设计工艺简单、占地面积小、运行费用低、运行方式灵活。当进水CODCr为900～1000mg/L时,出水可达到国家《污水综合排放标准》(GB8978—1996)中的一级标准,主要污染物CODCr≤100mg/L。　　[关键词]屠宰废水;SBR法;工程应用　　[中图分类号]X703.1　[文献标识码]B　[文章编号]1005-829X(2003)03-0062-03EngineeringapplicationofSBRtreatmenttoslaughter-housewastewaterHeJianhong(XiaolanInstituteforEnvironmentalProtectionandManagement,Zhongshan528415,China)Abstract:Theapplicationofsequencingbatchreactor(SBR)processtothetreatmentofslaughter-housewastew-aterispresented.Thisdesignissuitableformediumorsmall-sizedslaughter-housewastewateranditsmainstructuresareoilseparating,anaerobicadjustingchamberandSBR.TheSBRgoesthroughfiveperiods,i.e.wa-terinflowing,reacting,settling,drainingandleavingunusedperiods.ThedesignedSBRprocessischaracterizedbysimpletechnology,smallarea,lowrunningcostandflexibleoperation.WhentheinflowCODCrisintherangeof900～1000mg/L,theef
