*黄咏洲, 翟 俊, 何 强, 康岷春(, 400045):通过试验,研究了新型曝气生物滤池对城市生活污水的处理效果,考察了水力停留时间(HRT)和温度等的影响。结果表明,曝气生物滤池试验装置在流量为25.2~72L/h、含氧量为2~4mg/L、水温为10~25℃时滤池水中COD和SS的去除率为85%和95%。:曝气生物滤池;酶促填料:X703 :A :1006-7329(2006)04-0072-04StudyontheNewAeratedBio-filterforMunicipalWastewaterTreatmentHUANGYong-zhou,ZHAIJun,HEQiang,KANGMin-chun(KeyLabofThreeGorgesReservoirRegion'sEco-EnvironmentofMinistryofEducation,ChongqingUniversity,Chongqing400045,P.R.China)Abstract:Anexperimentwascarriedoutontheuseofanewtypeofaeratedbio-filterforthetreatmentofmunicipalwastewater.Theeffectofhydraulicretentiontime(HRT)andtemperatureontheperformanceofBAFwasstudied.Theresultsshowthatwhentheflowis25.2~72L/h,theamountofoxygenis2~4mg/Landthewatertemperature10~25℃,thebio-filtercanefficientlyreducetheconcentrationofCODandSSwiththeremovingrateof85%and95%respectively.Keywords:aeratedbio-filter;enzymaticmedium ,。,、、、、;,,-,,、。、、、、[1]。1 1.1 。1600mm×600mm×1500mm。1.2 B,COD250mg/L()、500mg/L();pH7.4~7.8。。,1 ,。、、,,20cm,、。、,、,。,,,。,270mm×100mm×1000mm,50mm,30mm,。60mm,80mm。第28卷 第4期2006年8月 重庆建筑大学学报JournalofChongqingJianzhuUniversity Vo.l28 No.4Aug.2006*:2006-02-22:“”(201BA60401):(1977-),,,,。。,2d,,COD70%,。,,。,。2 1 ()HRT/h/m3d-1COD/mgL-1/mgL-1/%/mgL-1/%(2002830~20021013 20.6~25.6℃)120.6124619221.95%4382.52%100.7420915426.32%5374.64%80.9227019228.89%5280.74%71.0626417832.58%4981.44%6.51.1425818926.74%11356.20%(20021013~20021212 11.0~20.6℃)120.6136725331.06%5385.56%100.7441526436.39%5985.78%80.9250925450.10%5888.60%71.0653423655.81%11678.28%2 ()HRT/h/m3d-1SS/mgL-1/mgL-1/%/mgL-1/%(2002830~20021013 20.6~25.6℃)120.611006238.00%298.00%100.741055943.81%199.05%80.921358934.07%596.30%71.0619613531.12%1492.86%(20021013~20021212,11.0~20.6℃)120.611126046.43%199.11%100.741205655.33%397.50%80.9216810537.50%398.21%71.0619210246.88%1492.71%2.1 COD、SS。1、2,COD80%,SS97%,。COD,,;。SS。2.2 (HRT)/,HRT,[2]。,HRT。HRT(1),HRT。1HRT,COD,HRT12h、10hCODHRT8hCOD3%(COD60),HRT7hCOD60,7h,COD。,HRTHRT,。HRT。,HRT,SS,,,SS。,CODSS,。,SS,:HRT,,,,,,,,HRT,,,SS;,,,。SS。SS,90%,97%。:,,。2.3 ,,()。,,,。,10℃,73第4期 黄咏洲,等:侧向流曝气生物滤池处理城市污水效能研究 HRT7hCOD,COD,。,,,。。,SS,Stocks,,。,。SS,。2.4 N、PNP,N、P[3]。。TP。3 ()HRT/h/m3d-1COD/mgL-1/mgL-1/%/mgL-1/%(2002830~20021013 20.6~25.6℃)120.618.604.4048.84%3.8055.81%100.747.094.2340.34%3.6049.22%80.927.625.2630.97%4.2544.23%71.068.705.8333.05%5.5536.21%6.51.147.256.4011.72%5.9517.93%(20021013~2002121211.0~20.6℃)120.617.204.3040.28%3.5051.39%100.747.354.5830.01%3.9845.85%80.928.025.2035.16%4.0549.50%71.067.804.6240.76%3.9848.97% 3TP50%,70%,P,P,P。,,P。TP。TPTP,P,P,P[4~6]。TN30%,20%。3 3.1 2COD。HRT12h、10h;HRT8h、7h。CODCOD,COD。,COD。,COD30%。。,。,,、、。、10%,COD70,60。,,,,,,,。、,。,COD,,;,。,CODCOD。2 COD3.2 DO。2~4mg/L[4,6]。,。1.5~2mg/L、2~2.5mg/L、2.5~3mg/L、3~3.5mg/L、3.5~4mg/L。1.5~2mg/L、2~2.5mg/L,,2.5~4mg/L,2.5~3mg/L,3mg/L,;,3~3.5mg/L。74 重庆建筑大学学报 第28卷4 4.1 ,。280mm×50mm×1000mm,20mm,,,Ф6mmФ10mm。。。4.2 ,,。。4.3 4 ()HRT/h/m3d-1COD/mgL-1/mgL-1/%/mgL-1/%200375~20031010 18.9~25.6℃13.40.6127616540.21%3288.41%11.10.7428513552.63%2690.87%8.90.9225715440.07%3486.77%7.71.0626813848.51%4085.07%7.51.1431319238.66%4286.58%6.31.2933018942.73%4885.45%4.81.7332517845.23%5284.00% 13.3、11.1、8.9、7.7,。5 ()HRT/h/m3d-1SS/mgL-1/mgL-1/%/mgL-1/%200375~20031010 18.9~25.6℃13.40.6139.2132.5616.96%15.6860.01%11.10.7438.5233.6512.64%16.3257.63%8.90.9240.2534.2514.91%18.5653.89%7.71.0637.6530.5618.83%18.5450.76%7.51.1441.6534.2317.81%19.5653.04%6.31.2942.2332.6522.69%20.3551.81%4.81.7338.7131.9817.39%20.5846.84%4.4 3,,,,,COD60。50%,TN。SS、TP。4.5 ,:1),、;2),;。3),,。SS。3 COD5 1)11~26℃,COD80%,SS95%。,CODSS,。2)HRT,CODSSHRT,HRT4.5h。3)TP,,,50%。4)pH7.3~7.8,。5),,COD、SS。:[1] ,,.〔M〕.:,1999.[2] ,.()〔M〕.:,2000.[3] PujolR,HamonM,KandelX,etal,Biofilters:flexible,relia-blebiologicalreactors〔J〕.WatSciTech,1994,29(10-11):33-38.[4] ,,,.〔J〕.,2000(9):9-11.[5] ,.〔J〕.,2002,(18):1-4.[6] ,.()〔M〕.:,2000.75第4期 黄咏洲,等:侧向流曝气生物滤池处理城市污水效能研究
