2陈文,左军,刘庆红 (,410004) 用微滤技术对长沙城市污水厂经2级处理后的城市污水进行微滤处理。结果表明,微滤技术对去除污水杂质的效果可靠、有效,尤其是对重金属的去除效果显著。经微滤处理后的2级污水适合于农业灌溉,而潜在危害性很小。 微滤;灌溉;城市污水;水质标准 X703   A   0517-6611(2008)18-07891-02QualityofMunicipalWastewaterwithMicro-filtrationTechnologyinTreatmentandReusinginIrrigationCHENWenetal (CollegeofCivilEngineeringArchitectureandMechanics,CentralSouthUniversityofForestryandTechnology,Changsha,Hunan410004)Abstract Micro-filtration(MF)unitwasusedtotreatthesecondarywastewatereffluentfromChangshawastewatertreatmentplant.TheresultsshowedthattheMFunitwasreliableandveryeffectiveinremovingwastewaterimpurities,especiallyheavymetal.ThequalityofthewastewatertreatedbyMFunitwassuitableforirrigationwithlowpotentialproblems.Keywords Micro-filtration(MF);Irrigation;Municipalwastewater;Waterqualitystandard  ,、。,32.83m3,42.03m3,21.9%;,31.19m3,43.40m3,28.30%。2010,280%,70m3[1]。1996,Brace[2]。、,,80%。2,。,2,,,、、[3-4],。,。1   1。,15m2,0.2μm,0.1MPa,3m3/h,30min,0.4MPa。30d,30min,24h。;;[5]。2 1,,Cl-;,BOD5、CODCr30%,(SS)80%。  Cl-243.4~275.4mg/L。Cl- 陈文(1978-),男,浙江舟山人,硕士,讲师,从事污水处理方面的研究。 2008-04-16,。,,Cl-140mg/L,Cl-54.65%。Cl-240mg/L,250mg/L,130mg/L,。,,,Cl-。1 Fig.1Testdevice,、,。5mg/L,30mg/L。12.6~15.3mg/L,13.9mg/L,1(12mg/L)。10.1mg/L,11.5mg/L,27.3%,,。Na+、Mg2+Ca2+,1000mg/L。。Na+。,;184mg/L,[6]。2158.4mg/L,,140.5mg/L,184mg/L。Mg2+Ca2+,pH,,;200mg/L,;120mg/L,,[7]。1,Mg2+、Ca2+120mg/L,。,JournalofAnhuiAgri.Sci.2008,36(18):7891-7892                    刘月娟  傅真治DOI:10.13989/j.cnki.0517-6611.2008.18.0221 ()Table1WaterqualityindexofsecondarysedimentationtankduringthetestItemInfluentRangeMonthlymeanEffluentRangeMonthlymean∥%RemovalrateIrrigationstandardpHpHvalue  5.2~7.8    6.5    8.1~5.3    6.7   -5.5~8.5BOD513.5~18.215.811.1~7.59.8   38.180CODCr43.5~58.451.041.3~30.536.230.2150SS16.8~21.319.14.3~3.43.880.3100DO4.7~6.25.56.4~4.65.5   --Kjeldahlnitrogen12.6~15.313.912.5~8.710.127.312()TotalP0.4~0.50.40.5~0.40.49.85Cl-243.4~275.4259.4246.1~235.7241.19.6250Sulfide0.6~1.00.80.9~0.60.82.61Na+146.8~158.4152.6142.6~138.4140.57.9-Ca2+63.4~92.278.884.2~58.671.49.4-Mg2+4.8~18.611.714.6~3.69.122.2- :mg/L。Note:Theunitofconcentrationismg/L.  ,,[7]。2 Table2 Heavymetalconcentrationaftermicrofiltertreatmentandagricul-turalirrigationstandardofmajorheavymetalmg/LItem2∥mg/LSecondarywastewaterdischargestandardEffluentIrrigationstandardTotalHg    0.050-0.001TotalCd0.1000.0050.005TotalAs0.500-0.050()Cr0.5000.0500.100TotalPb1.0000.0500.100TotalCu1.0000.0501.000TotalZn5.0000.0502.000TotalSe0.0200.020  2,2,2,,。,,,,。,DO,、、,DO[6]。DO5.5mg/L,,。3 2,、,2。,。,,,,,。,,。[1]南昌大学中国中部经济发展研究中心.中部地区水资源开发与利用研究[M].北京:经济出版社,2006:117-120.[2]BRACEHB,ABDELLAHAR.Recyclingnutrientsfrommunicipalwastewater[J].Desalination,1996,106(24):12-46.[3]卢桂兰,韩梅,李发生.北京市通州污灌区土壤环境质量监测和蔬菜重金属污染状况研究[J].中国环境监测,2005,21(5):54-62.[4]王国利,刘长仲,卢子扬,等.白银市污水灌溉对农田土壤质量的影响[J].甘肃农业大学学报,2006,41(1):79-82.[5]国家环境保护局.GB5084-92农田灌溉水质标准[S].1992.[6]ENSINKJHJ,ASLAMMR.Useofuntreatedwastewaterinpetri-urbanagricul-tureinpakistanrisksandopportunities[M].Colombo:InternationalWaterMan-agementInstitute,2002.[7]SHAMMIRIMA,SAFFARAA,BOHAMADS,etal.WastewaterqualityandreuseinirrigationinKuwaitusingmicrofiltrationtechnologyintreatment[J].Desalination,2005,185:213-225.(上接第7817页)20062845,83.5%。“”[7]。4 GIS、,2006,:;、;,,LISA2。[1]胡良民,苗长虹,乔家君.河南省区域经济发展差异及其时空格局研究[J].地理科学进展,2002,25(3):268-273.[2]毛道云,钱乐祥.河南省县际经济差异及其调控[J].郑州航空工业管理学院学报,2007,25(1):35-39.[3]刘旗.河南农村区域经济发展差异及对策[J].华中农业大学学报:社会科学版,2006,65(5):51-55.[4]黄杏元,杨昕.ArcGIS地理信息系统空间分析实验教程[M].北京:科学出版社,2006.[5]张松林,张昆.空间自相关局部指标Moran指数和G系数研究[J].大地测量与地球动力学,2007,27(3):31-34.[6]马荣华,黄杏元,朱传耿.用ESDA技术从GIS数据库中发现知识[J].遥感学报2002,6(3):102-107.[7]彭宝玉,覃成林.河南县域经济实力评价及空间差异分析[J].地域研究与开发,2007,26(1):45-49.7892             安徽农业科学                        2008
