A1A0A2A3A4A5A6A8IA9混凝吸附及化学氧化法深度处理焦化废水的研究摘要本文以焦化废水二级生化出水为供试对象，采用膨润土、凹凸棒石、次氯酸钙、PAC、PAM作为基本材料，对焦化废水进行深度处理。试验结果显示膨润土具有较高的吸附性能，当膨润土添加量为33G/L，PAC添加量为198G/L、PAM添加量为00132G/L时，COD去除率达到592，脱色率达到903；采用凹凸棒石作为膨润土的改性剂，可以提高焦化废水COD和色度的去除效果。当膨润土与凹凸棒石混合比例为4/1时，与单一添加膨润土相比，COD和色度去除率明显提高；添加无机氧化剂次氯酸钙能进一步提高焦化废水色度及COD的去除率。当次氯酸钙添加量为09G/L时，色度、COD去除率分别提高5、6左右。通过正交试验确定焦化废水深度处理中去除色度的最佳反应条件为膨润土G14凹凸棒石为46G26G/L，比例为4G291；次氯酸钙10G/LG30PAC为2333G/L、PAM为00266G26G/L。G4106化处理G1802的焦化废水CODG2022到631G26G80G/L，色度为20度。去除COD的最佳反应条件为膨润土G14凹凸棒石为40G/L，比例为4G291；次氯酸钙11G/L；PAC为16665G/L、PAM为00066G26G/L。G4106化处理G1802的焦化废水CODG2022到5818G80G/L，色度为30度，达到G119G3658水G4504合G2790G1474G947G4473G120G11G42G37G389G268G161996G12一级G947G4473。G3G3关键词焦化废水；深度处理；膨润土；凹凸棒石；次氯酸钙A1A0A2A3A4A5A6A8IIA9RESEARCHONADVANCEDTREATMENTOFCOKINGWASTEWATERBYCOAGULATION、ADSORPTIONANDCHEMICALOXIDATIONABSTRACTINTHISPAPER,MONTMORILLONITE,ATTAPULGITECLAY,CALCIUMHYPOCHLORITE,POLYALUMINIUMCHLORIDEANDPOLYACRYLAMIDEWERESELECTEDASEXPERIMENTALMATERIALSFORTHEADVANCEDTREATMENTOFCOKINGWASTEWATERRESULTSWEREASFOLLOWSMONTMORILLONITEEXHIBITEDHIGHADSORPTIONCAPACITYTHEREMOVALRATEOFCODANDCOLOROFCOKINGWASTEWATERWERE592AND903RESPECTIVELYWHENTHEADDITIONQUANTITYOFMONTMORILLONITEWAS33G/L,POLYALUMINIUMCHLORIDEWAS198G/LANDPOLYACRYLAMIDEWAS00132G/LMODIFIEDMONTMORILLONITEBYATTAPULGITECLAYCOULDIMPROVETHEREMOVALOFCODANDCOLOROFCOKINGWASTEWATERWHENTHERATIOOFMONTMORILLONITEANDATTAPULGITECLAYWAS41,THEREMOVALRATEOFCODANDCOLOROFCOKINGWASTEWATERMODIFIEDBYMONTMORILLONITEINCREASEDOBVIOUSLYCOMPAREDWITHPUREMONTMORILLONITEADDITIONOFINORGANICOXIDIZERCALCIUMHYPOCHLORITECANFURTHERIMPROVETHECOKINGWASTEWATERCOLORANDCODREMOVALWHENCALCIUMHYPOCHLORITEADDITIONLEVELWAS09G/L,THECOLORANDCODREMOVALRATEINCREASEDBY5AND6SEPARATELYBYORTHOGONALEXPERIMENTWEGOTTHEOPTIMUMREACTIONCONDITIONSTOREMOVECOLOROFTHEOFCOKINGWASTEWATERTREATMENTMONTMORILLONITEPALYGORSKITECLAY467G/LWITHARATIOOF41CALCIUMHYPOCHLORITE10G/L；PACIS2333G/L,PAMIS002667G/LCODOFOPTIMIZEDANDTREATEDCOKINGWASTEWATERDROPPEDTO6317MG/L,COLORDROPPEDTO20DEGREESTHEOPTIMUMCONDITIONSOFCOLORREMOVALOFAREMONTMORILLONITEPALYGORSKITECLAY40G/LWITHARATIOOF41CALCIUMHYPOCHLORITE11G/LPACIS16665G/L,PAMIS000667G/LCODOFOPTIMIZEDANDTREATEDCOKINGWASTEWATERDROPPEDTO5818MG/L,COLORWAS30DEGREES,WHICHACHIEVEDTHE“INTEGRATEDWASTEWATERDISCHARGESTANDARD“GB89781996LEVEL1A1A0A2A3A4A5A6A8IIIA9G3KEYWORDSCOKINGWASTEWATERADVANCEDTREATMENTMONTMORILLONITEATTAPULGITECLAYCALCIUMHYPOCHLORITEA7A10A11A12A13A14A15A16IVA17目录摘要IABSTRACTII目录IV1绪论111课题背景112焦化废水生化出水的特点1121焦化废水的G2303G41831122焦化废水的水G4393G3467G13162123焦化废水的G3602G17253124焦化废水的处理G1935G3308G3747G44653125焦化废水生化处理G1629G40286126焦化废水生化出水G3747G4465813焦化废水深度处理技术8131吸附G14458132化G3888氧化G14459135G1496G2668G1891性G3442生G3678G144510136G4316G1316加氯G14451114本研究的意义及内容112材料与方法1321实验材料1322实验仪器1523分析方法163实验过程与结果分析17A18A19A20A21A22A23A24A25VA2631PAC/PAM对焦化废水色度及COD去除率的影响17311G3244验过G110517312G3244验结果G3465G25301732膨润土对焦化废水COD及色度去除率的影响18321试验过G110519322结果与分G36851933凹凸棒石改性膨润土对焦化废水脱色及去除COD的影响20331G3244验过G110520332G3244验结果G3465G25302134次氯酸钙氧化对焦化废水COD去除和脱色的影响22341G3244验处理22342G3244验结果与G3465G25302335正交试验23351正交试验G3201G194524352正交试验G3316G2156分G36852636正交试验最佳配比验证27361正交试验色度去除G3984剂添加量最佳G2821比验G435527362正交试验COD去除G3984剂添加量最佳G2821比验G43552837成本分析28结论30附图错误未定义书签。致谢31参考文献32A27A28A29A30A31A32A33A341A351绪论11课题背景煤炭是我国的主要能源，随着我国经济的快速发展，对焦炭的需求量日益剧增，焦化行业不断扩大，焦化废水的产生量不断增加。而焦化废水的成分十分复杂，除含有较易生物降解的物质如酚及其衍生物外，还含有多种难以被微生物降解的芳香族化合物或有生物毒性的有机物以及大量的氨盐、硫化物、氰化物等无机盐类。如果直接排入水体，将造成严重的水体污染。G11458G2081，G15441G9994G3324G10627G3671G5049G12255G1166G3775的不断G2174G2159G994G6518G13046G1025G3324G8847G10714G8504类污水G7053G19766有G1114G7044的G12373G11784，G1306G3324焦化废水G3800G10714G1025还G7234G17953G4396G3324着G20056G3800G10714G17165G11004G20652外，经生物G3800G10714G2530的G13007G13491排水水质G3324COD含量及G14406G5242等G7053G19766不能G17810G7643等G19394G20076。12焦化废水生化出水的特点121焦化废水的来源焦化G2390主要生产煤G20652G9213G16022解产生焦炭G2656煤G8680，G5194G3250G6922化G5049产G2709焦G8845、G14531、G14828等，G3252G8504焦化废水是煤G9921加G5049G17819G12255产生的，G7481G14270G9872焦G17819G12255G1025的G8939煤、G10072焦、G2115产G2709加G5049G2656G12946G2058等G10627G144221，G2528G7114G3324煤G8680G1940化G2656化G5049产G2709G3250G6922G17819G12255G1025G1075有G18108分废水产生。主要废水排G6930源有2G7261煤G20652G9213G16022解G2656煤G8680G1931G2376产生的G2109G1325氨水废G9094。G8504G1038焦化G2390主要排G6930源，G6164排废水量G2356G1852G2390排G6930量的G980G2334以G990，其水质复杂、G13464分种类G13333多G1000污染物G8999G5242较G20652，除含有氨、氰、硫氰G7693等无机污染物外，还含有酚、G8845类、G14828、G2549G2890、G2957G2845、G14993G2656其G4439G12276G10627芳G9879化合物等，是G11458G2081较难G3800G10714的废水G1055G980。其G1025主要污染物NH3NG10383000G7945000MG/L，CODG10386000G79410000MG/L。2煤G8680G1940化G17819G12255G1025煤G8680G13468G1931G3132G2656G12907G14531分G12175G8145排水等。G6164含污染物G1038酚、氰及其G4439CODG13464分等，不含氨G1000G8999G5242G11468对较G1314。A36A37A38A39A40A41A42A432A443煤焦G8845、G12946G14531及其G4439G5049G14414G17819G12255的排水。G6164含污染物G1038酚、氰及其G4439CODG13464分等。水量较G4581，污染物G8999G5242较G1314。122焦化废水的水质特点1成分复杂3焦化废水G13464成复杂，其G1025G6164含的污染物G2499分G1038无机物G2656有机物G1016大类G726无机物G980G14336以G19145盐G5430G5347G4396G3324，G2265G6336NH42CO3、NH4HCO3、NH4HS、NH4CN、NH4COONH4、NH42S、NH4CL、NH42SO4、N
