SBR工艺处理造纸废水试验研究

①SBR方　士**　詹伯君*　陈国喜*　潘凛溥**(*,310002)(**,310029)　　本文介绍SBR造纸废水处理工艺研究。考察了SBR工艺的COD处理效果,以及pH值、曝气时间、冲击负荷等对COD去除率的影响。运行结果表明,pH为6.0～8.0,进水COD为1000～1500mg/L,COD的去除率达到82.5%。:SBR,造纸工业废水,废水处理SBR、、、、、,、。SBR,SBRCOD,pH、、COD,。图1　SBR试验装置示意图1　实验材料与方法1.1　,10L。,50%。。,。1。1.2　,、、。,COD、BOD、SS、、、。,pH6.0～8.0,COD1000～2000mg/L,BOD/COD0.20～0.35。1.3　。1L,3L,7L100mLNH4ClNaH2PO4COD∶N∶P=100∶5∶1。4L,4L100mL。5d,,。,5L,5L,第25卷　第2期1999年4月　　　　　　　　　　　　　　TECHNOLOGYOFWATERTREATMENT　　　　Vol.25No.2Apr.,1999①:1998-02-13　　　　15d,,,,,15%～20%。COD897mg/L,12h,COD206mg/L,77%。,。2　结果与讨论2.1　SBR,。,。,COD,,,,。,,,COD1082mg/L,COD,1。1　COD(h)24681012COD(mg/L)812576282263241214COD(%)25.046.873.975.777.780.2　　6h,COD73.9%,,,6h。2.2　pH,pH4～9,pH6.5～8.5。WinRinsou(1975),pH,pH。pH6.0～8.0,、pH,6h,pHCOD,2。2　pHCODpHCOD(mg/L)COD(mg/L)COD(%)696321376.07121328176.98114226876.52.3　15d,SBR,COD79.2%,85.8%,82.5%。,。,COD271mg/L,208mg/L,。2.4　,。SBR,,3。SBR5,1#1。,1-4#12d,。:12h(1h;6h;1h;1h;3h)。12#、3#、4#,3L/,1123　　　,SBR1#。2。3　COD(mg/L)BOD(mg/L)pHSS(mg/L)1#14583727.83602#1464358142783#148135243814#645016317.91284图2　冲击负荷的试验结果2.5　SBR,35,20%25%。,0.55kWh/t,0.60/kWh。0.33/t。3　结　论,SBR:0.5h,6h,1h,0.5h,。8h。,pHpH6.0～8.0。:COD82.5%,,,。SBRpH,,,。SBR,、、。EXPERIMENTALSTUDYOFPAPERMAKINGWASTEWATERTREATMENTBYSBRPROCESSFangShiandPanLingbo(Machinery&ElectricDesignInstituteofZhejiangProvince,Hangzhou310002)ZanBojunandChengGuoxi(Environment&ResourceCollege,ZhejiangUniversity,Hangzhou310029)Abstract:ThearticleintroducestheresearchonpapermakingwastewatertreatmentbySBRprocess.ThestudymainlyfocusedtheinfluenceontheefficiencyofCODofSBRprocessaswellastheinfluenceontheremovalrateofCODexertedbypH,aerationtime,impactload,respectively.TheoperationresultshowedthattheremovalrateofCODwas82.5%undertheconditionofpH6-8andinfluencewaterCOD1000-1500mg/L.Keywords:SBR,papermakingindustrialwastewater,wastewatertreatment12425　2
