*王 涛, 赵 娜, 邓荣森, 聂卓娜, 麦松冰( , 400045):通过对多种连续流除磷脱氮工艺的时空分析,集成并构建了一种多环反应器处理系统,在此基础上,通过正交试验,找出了在低碳源条件下影响污水脱氮除磷效果的重要因素,提出了低碳源条件下生物除磷脱氮的适宜工艺控制参数,为类似条件的污水处理工艺设计和运行提供了参考。:低碳源;脱氮除磷;多环反应器:X703 :A :1006-7329(2005)06-0062-05ResearchontheStrengtheningEffectoftheNitrogenandPhosphorusRemovalbytheMulti-loopReactorinLowCarbon-resourceConditionWANGTao,ZHAONa,DENGRong-seng,NIEZhuo-na,MAISong-bing(CollegeofUrbanConstructionandEnvironmentalEngineering,ChongqingUniversity,Chongqing400045,P.R.China)Abstract:Amulti-loopreactorisconstructedbasedonanalysisoftemporalandspatialcharacterofseveralcontinuouscurrentnitrogenandphosphorusremovalprocessinthispaper.Throughcrossexperimentdesign,theimportantfactorstoinfluencetheeffectofthenitrogenandphosphorusremovingunderlowcarbon-re-sourceconditionwerefound,andthefeasiblecontrolparametersofthebiologicalnitrogenandphosphorusre-movalprocessunderlowcarbon-resourceconditionwereputforward.Theresultsarevaluablefordesignandoperationofwastewatertreatmentprocesswithsimilarconditions.Keywords:lowcarbon-resource;nitrogenandphosphorusremoval;multi-loopreactor,,。,,,。1。1 CODcrBOD5TNNH3TPBOD5/TNBOD5/TP152.7100.832.2-22.317.21.960.353.15120663.630.718.722.86.913.732.272.117.1-138.630.524.0--4.900.964.528.3277.798.137.2-25.71.034.292.482.622.9280125256.3--1585.08.3 1,,BOD5/TN4,BOD5/TP,14。,,。,,第27卷 第6期2005年12月 重庆建筑大学学报JournalofChongqingJianzhuUniversity Vo.l27 No.6Dec.2005*:2005-05-18: (1964-),,,,,。。,,,,。,,、,、。,,,,1 ,。1 [1]1,A2/O,,、、,,。,,,。,,,。,:2∶8,80%,。,20%,。,Orbal,,,,,。,OrbalOCO,。,,,,。,,A2/O、、OCO、Orbal,,。,:∶∶=5.89∶3.06∶1∶0.57。2 2.1 2。2.2 ,3。2.3 ,、、,10～15/15～20/20～25d、8/10/12hr、200%/300%/400%、DO0.5～1/1～2/2～3mg/L,,2。2 2 /d/%HRT/hrDO/mg/L20～25400120.5～120～2530081～220～25200102～315～2020080.5～115～20400101～215～20300122～310～1540082～310～15200121～210～15300100.5～1 :HRT63第6期 王 涛,等:多环反应器在低碳源条件下强化脱氮除磷效果 3 3.1 3 COD/mgL-1131.9144.113293.2109.9126.5106.5140.4142.23730.934.923.13738.234.73447.7/%71.878.673.375.465.1696775.166.7NH3-N/mgL-117.9517.9519.0712.4518.1118.4817.8220.0719.830.290.330.510.420.520.540.190.190.27/%98.498.297.496.797.296.89999.298.7TP/mgL-13.132.752.411.542.172.472.333.193.051.841.961.931.251.461.781.552.252.09/%41.331.52018.83227.732.530.431.1TN/mgL-124.9727.2828.9818.9227.5228.0927.0832.2129.417.259.4912.7211.2618.6418.3818.6120.9722.33/%73.4465.256.140.532.334.531.333.824.1MLSSmgL-1213319631781166513971300744724714SV30%161615141312877SVImLg-1778183868993102100104kgCOD/kgMLSSd0.0890.1730.1310.1260.1250.1360.2900.2940.318kgMLSS/gCODd0.790.440.550.720.690.670.440.430.403.2 ,,4。4 123HRT4DOTPmgL-1TNmgL-11110～15120031221～23.192.2530.3732.2120.9733.7732.072215～2012001810.5～11.541.2518.8318.9211.2640.5129.673320～25120021032～32.411.9519.9928.9812.7256.1238.054110～15230021010.5～13.052.0931.1229.4122.3324.0827.65215～20230031232～32.471.7827.6728.0918.3834.5431.116320～2523001821～22.752.0331.5327.289.4965.2248.387110～1534001832～32.331.5532.4527.0818.6131.2931.878215～20340021021～22.171.4632.0327.5218.6432.2632.149320～25340031210.5～13.131.9741.2627.287.6973.4457.35K191.54100110115328.24K292.92107.0897.79112.59K3143.78121.36120.53101.0352.2421.5722.7413.58**********:****;***;**;*。3.3 ,,,,,。3.3.1 污泥龄 34,C,,N、P,23d13d,,MLSS2100700mg/l,N、P,N70%30%。,,,,,,。,64 重庆建筑大学学报 第27卷,,NO3--N,,。,。[2],PHB,,。。,,PHB;,、,[3]DPB,,PHB。,PHB,、,。,,,,。SVI,,,。,,C,,CC。3.3.2 水力停留时间(HRT) ,,,12hrTN、TP,,、,,,,,,。,。,DO=0.5～1mg/L,,,。,,HRT。3.3.3 回流比 NO3--N。,,。,,。,,。,,,,,,,。,20%,。,,,,,。,,400%,400%。3.3.4 DO ,,,。TN,DO,,DO0.5～1,,,。,、,,,SRT=20～25d,HRT=12hr,=400%,DO=0.5～1mg/L,34%。,,SRT、HRT、DO,SRTHRT。,65第6期 王 涛,等:多环反应器在低碳源条件下强化脱氮除磷效果 DO,SRT30d,HRT16hr,:TN81.5%;TP1,TP67%,5。,。5 12345COD/mgL-1145.94144.49136.16144.76127.36139.7424.1526.1325.2630.4821.0825.42/%83.4581.9281.4578.9483.4581.84NH3-N/mgL-116.2021.4020.9424.1818.5220.250.280.560.700.550.260.47/%98.2797.3896.6697.7398.6097.73TP/mgL-12.943.122.712.521.912.640.850.980.710.840.850.8571.0968.5973.8066.6755.5067.13TN/mgL-124.6232.5331.8336.7528.1530.784.625.156.896.245.375.65/%81.2484.1778.3583.0280.9281.54MLSS/mgL-1211422102237217621892185SV30/%16.015.816.516.216.016.1SVI/mLg-175.771.573.874.473.173.74 1),、,SRT、HRT、、,。2),,0.5～1mg/L,。,,、。3),SRT=30d,HRT=16hr,=400%,DO=0.5～1mg/L,,,。:[1] G.P.LeslieGrady,Jr.GlenT.DaiggerHenryC.Lim.()〔M〕.:,2003.[2] .〔J〕.,2002,18(7):83-85.[3] ,.〔M〕.,2003,25(5):33-35.[4] ,.〔J〕.,2005,27(5):83-86.66 重庆建筑大学学报 第27卷
