改性煤矸石吸附处理印染废水的试验研究吴俊峰

吴俊峰,余海静,王现丽(河南城建学院环境与市政工程系,河南平顶山467044)　:利用改性后的煤矸石吸附处理印染废水,分别考察了改性煤矸石粒径、投加量、振荡吸附时间对印染废水处理效果的影响。试验结果表明:在原水COD为3298.8mg/L,色度为1100倍,投加4g粒度为120目的改性煤矸石与50mL废水反应5min时,改性煤矸石对COD和色度的吸附去除率分别达到46.2%和83.7%,出水COD和色度分别为1774.8mg/L、180倍。该项研究为改性煤矸石作为水处理吸附剂在印染废水预处理中的应用提供了理论依据,同时也为印染废水的处理提供一种途径。:改性煤矸石;印染废水;处理效果;影响因素:TD98;X703　　　:B　　　:1008-4495(2010)06-0027-02:2010-03-05;2010-08-20修订:河南省教育厅科技攻关项目(2008A610005):吴俊峰(1980—),男,河南孟州人,在读博士研究生,讲师,研究方向为污水处理理论与技术。E-mail:[e-mail]。　　,,,、。,,400hm2,1.5～2.0t/a[1-2],“”[3]。,[4]、[5]、[6],,。,,,。,。,、,。,。1　1)。—(650℃,2h,)—(CHCl=1.2mol/L,1h)——(105℃,1h)。2)。,,COD3298.8mg/L,1100。3)。COD,。2　2.1　,40,60,80,100,120,180,2g50mL,2h,,COD,,1。1　,,COD。·27·201012　　　　　　　　　　矿业安全与环保　　　　　　　　　3761,40120,COD42.21%48.54%,21.99%74.24%。120180,COD48.54%49.71%,1.17%,74.24%76.99%,2.75%。,,120,180,,。120。2.2　1201,2,4,5,6,8g,50mL,2h,,2。2　,,COD。2,04g,COD055.56%,088.91%,55.56%88.91%。4g8g,COD55.56%60.23%,88.91%91.11%,,COD4.67%2.2%。,。4g。2.3　1204g50mL,5,10,15,30,60,90,120,180,240minCOD,,3。3　,05min,COD046.2%83.07%。5min,;5min180min,COD46.02%57.31%,83.07%90.18%,11.29%7.11%。5min。3　1)COD。COD3298.8mg/L,1100,4g12050mL5min,COD46.2%83.07%,COD1774.8mg/L、180。2)。3),。:[1]张吉雄,缪协兴.煤矿矸石井下处理的研究[J].中国矿业大学学报,2006,35(2):197-200.[2]刘迪.煤矸石的环境危害及综合利用研究[J].气象与环境学报,2006,22(3):60-62.[3]马超,康建荣,何万龙.煤矸石排放对生态环境影响的分析[J].煤矿环境保护,2000,14(6):71-73.[4]李剑,刘贤群.我国煤矸石制砖的现状与发展[J].煤炭加工与综合利用,2001(6):24-25.[5]江洪清.煤矸石对环境的危害及其综合治理与利用[J].煤炭加工与综合利用,2003(3):43-46.[6]文忠和,卢清兰.煤矸石资源化开发利用途径[J].萍乡高等专科学校学报,2002(4):39-42.(责任编辑:李　琴)·28·201012　　　　　　　　　　矿业安全与环保　　　　　　　　　376EnglishAbstractsofThisIssueExperimentalStudyofMethane-coalDustCompoundExplo-sioninaClosedTube(1)-Experimentsofmethane-coaldustcompoundexplosionwithlowignitionenergywerecarriedoutina1.2mlongverticaltube.Studywasmadeontheinfluenceofdifferentinitialstateparametersinclu-dingmethaneratioofcoaldustconcentration,coaldustparticlesizeandignitiondelaytimeuponthecompoundexplosioncharacteris-tics.Theresultsshowedthattheexplosionpressurerosesignificant-lywiththespeed-upofflamepropagation,themaximumexplosionriserateappearedattheinitialstageoftheexplosionanditreachedthemaximumvaluewhenflamepropagatedtotheendofthetube;afterthecoaldustwasaddedintolowconcentrationmethane,theexplosionpressuremarkedlyincreased;thesmallerthecoaldustparticlesize,thelargerthecompoundexplosionpressureandthefastertheexplosionpressurerose;themaximumexplosionpressureandthepressureriserateincreasedfirstandthendecreasedwithcoalconcentrationandignitiondelaytime,soapeakpointexisted.NumericalSimulationofGasandVentilationSafetyinCoalandGasOutburstProcessSimula-tionLaboratory(5)-Thecoalandgasoutburstsimulationtest-standdevelopedbyChongqingUniversitycansimulatecoalandgasoutburstprocessindifferentconditions,however,thehiddenriskbroughtbya-mountofmethanegascan′tbeignored.Inordertoresearchthegasenrichmentandmigrationregularityaftercoalandgasoutburstandthedegreeofhiddenrisk,CFDsoftwareFluentwasusedinthispapertosimulatethemethanegasenrichmentstatusandcorrespondingsafetycountermeasureswerethusputforwardaccordingtothenumericalsim-ulationresults.Itwasfoundfromthecontrastanalysisofnumericalsimulationresultsandthegasconcentrationmeasuredatthesitethattheyhaveagoodconsistency,thisthusprovidedscientificbasisforthesafeconstructionoflaboratories.SimulationonReleasingCharacteristicsofCd,ZnandCuinSoilPollutedbyAcidRain(13)-Inthispaper,studywasmadeonthereleasingcharacteristicsofheavymetalCd,CuandZninthesoilpollutedbyacidrainandcomparisonwasmadeontheirreleasingdifferencefromthenaturalsoilandpollutedsoilbyacidrainthroughleachingexperimentsofsimulatedacidrainfornaturalsoilandpollutedsoil.TheresultsindicatedthatthereleasingamountofCdandZninnaturalsoilin-creasedlinearlywiththeincreaseoftheleachingamountofsimula-tedacidrain,thestrongertheacidityoftheacidrain,thelargerthereleasingamountoftheheavymetals,therewasamarkedlinearrelationbetweentheaccumulativeamountsofthreeheavymetals,thereleasingsequenceoftheheavymetalswasZnCdCuandtheabsorbedsequenceofheavymetalsbythenaturalsoilwasCuCdZn.Inthepollutedsoil,thereleasingmodeofCd,ZnandCuincreasedlogarithmically,thereleasingsequenceofheavymetalswasCdZnCuandtheabsorbedsequenceoftheheavymetalsbythepollutedsoilwasCuZnCd;theacidityincreasehasalittleinfluenceonthereleasingamountofCd,ZnandCuinpollu-tedsoil.Thepollutedpossibilityofnaturalsoilbyheavymetalsun-dertheactionofacidrainwasrelativesmallduetolessreleasingamountofheavymetalsfromit.EmulationStudyonFlyingProcessofAir-boostingCarrierinLimitedMineSpace(16)-Inthispaper,theflyingprincipleofair-boostingcarrierinthelimitedminespacewasdescribed,themathematicmodelforcarrierflyingprocessandropehaulageforcewasestablished,thenumeri-calemulationofcarrierflyingprocessandthejointemulationcal-culationofitslaunchingprocesswerecarriedout,thelaunchingdeviceandtestsystemforthecarrierweredesignedandlaunchingtestswereconducted,thecorrectnessandconfidenceofthecarrieremulationstudywereverified,andtheflyingfeasibilityoftheair-boostingcarrierinlimitedminespacewasfinallyobtained.ResearchonFailureRegularityofOverburdenRockinP
