反渗透处理橡胶工业废水的研究

①尤作亮(,100084)　　本文采用低压中空醋酸纤维反渗透装置和聚砜酰胺反渗透装置对齐鲁石化橡胶厂工业废水处理进行了试验研究。结果表明,反渗透对橡胶废水的总溶解固体、硬度、有机物都有较高的去除率,对总盐量的去除率稳定在85%左右,而对可溶性SiO2、和碱度去除率较低,试验表明加强水质的预处理是该废水处理的重要环节。:橡胶废水,反渗透,除盐,,,。,,,[1,2],。,、、[1,3,4]。,,,。1　废水概况,,,:,,,1。1　　COD(mg/L)SS(mg/L)(mg/L)()()(μs/cm)(mgN/L)80-15015-602-1015-4015-4020002.5-5RO1530.030020002.5-5　　,,,、,,,1。第22卷　第5期1996年10月　　　　　　　　　　　　　　TECHNOLOGYOFWATERTREATMENT　　　　Vol.22No.5Oct.,1996①:96-02-13、、、图1　反渗透处理试验装置示意图2　试验2.1　1,TRFO(CA)FSJ42-1.22(PSA)。2.2　2。2　(MPa)(℃)pH(L/h)(%)CA1.220-255-6≤48090PSA1.215-354-8≤4600-700803　　　　ⅠⅡⅢ　　　　　　(MPa)0.5-0.80.55-1.00.5-0.920.970.91(m3/h)0.130.031.950.661.870.6423.0%33.8%34.2%(μs/cn)207041019203002380360(%)80.284.484.9TDS(mg/L)162036154032SiO2(mg/L)10.55.010.34.0(mgN/L)4.560.254.480.20(mgN/L)1.050.301.020.37Fe2+(μg/L)30303030Cu(μg/L)0.0050.0050.0050.005pH6.5-7.56.5-7.56.5-7.56.5-7.56.5-7.56.5-7.5COD(mg/L)2687330SS(mg/L)103029122　5　,2.3　,COD、TDS、pH、Fe2+、Cu、SiO2、,、,,《》。3　运行结果及讨论19911119927,,,3。TRFO,,130L/h,,95%。,,70%。,。,。,COD26mg/L,4,,、、,。FSJ42-1.22,,,COD10mg/L,,2m3/h,0.6-1.0MPa,34%。3.1　,79%-90%,2000μs/cm,400μs/cm,(450μs/cm)。,,,,。4.5mgN/L0.2mgN/L,95%,,。1.0mgN/L0.3mgN/L,70%,,HCO-3。3.2　SiO2、Fe2+、CuSiO2,50%,,Fe2+Cu,。3.3　TDSCOD,100mg/L,95%,,,COD60%,。,CODCOD10mg/L,,COD,TDS,85%,TDS,90%。[5,6],GC/MS-COM,GC/MS,300,,[7]。,COD。,,29222　5　　,COD。,,,。4　结　　论,,,。TDS、、,90%,85%,SiO2,70%。,,。,,,,。1　,,,1990,8(3):58-602　,,,1985,11(6):13　,-,,1985,6(4):2-54　,,,,19895　,Suwannee,,1991,3:18-246　(),,,,,19897　McCarty,PLetal,WaterFactory21,InorganicOrganicandBiologicalQualityofReclaimedWastewaterandPlantPerformance,DepartmentofCivilEngineering,StanfordUniversity,Techmi-calReport,No.226,1978STUDYOFRUBBERWASTEWATERTREATMENTBYREVERSEOSMOSISPROCESSYouZuoliang(DepartmentofEnvironmentalEngineering,TsinghuaUniversity,Beijing100084)Abstract:TheexperimentalstudyofrubberwastewatertreatmentbyROprocesswithCAandPSAmembranehasbeencarriedoutinthisthesis.Theresultsindicatedthatreverseos-mosisunithashigherremovalrateoftotaldissolvedsolids,hardnessofwater,organicmat-terandlowerremovalrateofdissolvedSiO2andbasicity.Theremovalrateofsaltis85%moreorless.Keywords:rubberwastewater,reverseosmosis,saltremoval29322　5　,
