地下土壤渗滤系统处理农村生活污水试验分析华文才

:2008-10-26:(1969-),,,,.:1005-0523(2008)06-0006-05华文才,冯益敏,朱炳泉(,201800):建设地下土壤渗滤系统处理农村生活污水试验工程.通过取样检测,数据进行分析,系统对COD、BOD5、NH3-N、TP的平均去除率分别达到了89.78%、78.9%、97.13%和95.03%,效果理想.系统的出水方式对BOD5、NH3-N的去除有一定的影响,而上部作物的种类对处理效果略有影响.系统造价低,管理简单,卫生条件好,是污水资源利用的较好方法.特别适用于零星分散排放污水的治理,在广大农村具有较大的应用价值.　　:生活污水;就地处理;土壤渗滤;工艺原理:X32　　　　　　:A、,,.、、、.,、、.,,,,.,,、[1].2090,.,,.,.,.1　1.1　:,,,.—※—※　—※—※(),、.,,,.1.2　70m3/d.,256200812　　　　　　　JournalofEastChinaJiaotongUniversityVol.25　No.6Dec.,2008,BOD530～80mg/L,COD100～250mg/L.1.3　:;;..,:30～40L/(m2.d)[2、3],BOD51～10g/(m2.d)..,.60L/(m2.d),:F=70/0.06=1170m2.,3,:1#17m3/d,2#33m3/d,3#20m3/d.,,,.,1.5m,.,,.3:14m×20m=280m2,22m×25m=550m2,17m×20m=340m2,1170m2.1.4　,1.1　6.,:,,,.,、,20～40mm,,;,80cm,、,.“”:,20～40mm,,,,.:,,,,.:,22.,.“”,.,.1.5　,1#,2#、3#.1.6　,:(1),,.(2),,.76,:(3),.(4),、、、.(5)、,,.1.7　,4,1～2h.2,1#、3#,,,,.2#,,.2.2　2.1　9,.20084,35,1,1～3(:m3/d).1　1#mg/LCODBOD5NH3-NTP2008-04-0414.6180.015.831.05.222.51.108.550.6632008-05-0616.1342.015.746.08.145.70.308.580.7252008-06-0515.0164.016.039.07.037.10.348.610.7652008-07-0817.2170.017.442.08.042.30.428.650.8772008-08-0616.442.013.814.03.711.21.338.710.8812　2#mg/LCODBOD5NH3-NTP2008-04-0223.3140.016.227.08.641.01.5711.870.2402008-05-0625.8384.018.749.012.344.32.0011.50.2312008-06-0526.0180.022.041.010.039.72.3910.460.2112008-07-0830.2314.017.948.08.050.31.8813.820.4382008-08-0627.162.014.916.09.137.54.1514.90.4893　3#mg/LCODBOD5NH3-NTP2008-04-0215.682.022.329.05.831.40.335.320.1382008-05-0616.2280.019.451.02.949.30.255.510.1402008-06-0518.492.017.034.06.832.00.315.680.1472008-07-0819.7220.017.645.07.548.30.2411.890.4382008-08-0620.258.019.118.09.143.00.4612.10.457　　1～3,,4～6..COD89.78%,BOD578.9%.CODBOD517.49mg/L7.47mg/L,.BOD5、,.60mm/d,.8　　　　　　　20084　1#%CODBOD5NH3-NTP95.4183.2399.3492.2567.1473.5788.1389.8691.2481.4097.8090.935　2#%CODBOD5NH3-NTP95.1383.3396.2697.9975.9743.1388.9396.7291.6973.4894.3797.436　3#%CODBOD5NH3-NTP93.0794.3199.8397.4667.0749.4498.9396.2286.9781.8699.2296.742.2　BOD5,.,,、、.,,,..,97.1%.、.,,,.,.,,.,,,.,,.,,,,.,,,NH4+,NO2-,NH4+NO2-N2[3].,、、,,..,9.74mg/L,0.456mg/L,95%.,,.BOD5、NH3-N,2#1#、3#.2#,,,.,,.,.,,.、、、.,,.[4]..、、,,,.、.,.,,,96,:,.,,COD,BOD5,.NH3-N,.3　(1)9,..、,..(2).,COD15mg/L,BOD510mg/L,NH3-N5.0mg/L,TP1.0mg/L,,.(3),、.,,..(4)、、、,.:[1]　,　,,.[J].,2002,3(4):47-48.[2].[S].:,1997.12.[3],　,.[J].,2006,(4):130-133.[4],,.[J].,2000,16(5):12-15.AnExperimentalAnalysisoftheSubsurfaceSoilInfiltrationSystemforRuralDomesticSewageTreatmentHUAWen-cai,FENGYi-min,ZHUBing-quan(ShanghaiJiadingWaterEngineeringDesign&ResearchInstituteCo.LTDShanghai201800,China)Abstract:Atestprojectofthesubsurfacesoilinfiltrationsystemforruraldomesticsewagetreatmentisbuilt.Throughsomesampleinspectionsanddataanalysisofthesystem,theaverageremovalratesofCOD,BOD5,NH3-NandTPcanrespectivelyreach89.78%,78.9%,97.13%and95.03%,whichhaveidealeffects.TheeffluentdischargingmodesofthesystemhassomeinfluenceontheremovalratesofBOD5andNH3-N,whilethespeciesofthecropsontheupperparthasalittleeffectonthetreatmentefficiency.Thissystemhastheadvantagesoflowinvestment,convenientoperationman-agement,andgoodsanitationconditions.Itisabettermethodtousesewageresourceandamoresuitablesystemfordis-perseddomesticsewagewhichhasagreatvalueinapplicationinthevastruralareas.Keywords:domesticsewage;onsitetreatment;subsurfacesoilinfiltration;technologicalprinciple(:)10　　　　　　　2008
