摘　　要： 本课题采用生物法结合化学混凝及生物活性炭技术对制浆废液－－制浆黑液及漂白Ｅ１段废水进行处理，并对微生物的驯化及培养进行了探讨．研究结果表明：处理黑液的厌氧微生物驯化时间为３０ｄ，处理漂白Ｅ１段废水的为２５ｄ；处理黑液的好氧微生物驯化时间为２ｏｄ，处理漂白Ｅ１段废水的为２５ｄ．制浆黑液经化学预处理－－厌氧微生物－－好氧微生物－－化学混凝综合技术处理后，ＣＯＤ从１４５００ｍｇ／Ｌ降至１４０３．８ｍｇ／Ｌ，总去除率为９０．３％，木质素从６４２６．６ｍｇ／Ｌ降至１９１．ｌｍ／Ｌ，总去除率为９７·０％；经化学预处理－好氧微生物－生物活性实处理后，ＣＯＤ从７４０５·２ｍｇ／Ｌ降至３０３．５ｍｇ／Ｌ，总去除率为９６．０％，木质素从３５２０ｍｌ／Ｌ降至２９．４ｍｇ／Ｌ，总去除率为９９．２％．漂白Ｅ１段废水经过厌氧微生物－化学混凝－好氧微生物－生物活性炭处理后，ＣＯＤ从５２６５．ｌｍｌ／Ｌ降至５１５．８ｍｌ／Ｌ，总去除率为９０．２％，本质素从１１３０ｍｌ／Ｌ降至１３ｍｌ／Ｌ，总去除率为９８．８％，色度从６４０度降至２０度，总去除率为９６．８％． he paper in about the microorganiam combining with chemieal arded flocculationand biologically activated earbon process for pulping waste liquor-pulping black liquor and^^Biological Method and Chemical Fiocculation Treatment for Pulping Waste Liquor$Chen Min; Zhu Youchung ;Song Xiaogang ;Liu Hong(Dupartment of Environment and Pesourle Engineering)Song Xiaogang(Chemical Engineering)Liu Hong(Department of Environment and Resource Engineering)Abstract: The paper in about the microorganiam combining with chemieal arded flocculationand biologically activated earbon process for pulping waste liquor-pulping black liquor and^^Biological Method and Chemical FiocculationTreatment for Pulping Waste Liquor$Chen Min; Zhu Youchung ;Song Xiaogang ;Liu Hong(Dupartment of Environment and Pesourle Engineering)Song Xiaogang(Chemical Engineering)Liu Hong(Department of Environment and Resource Engineering)Abstract: The paper in about the microorganiam combining with chemieal arded flocculationand biologically activated earbon process for pulping waste liquor-pulping black liquor and bleaching E1 stage wastewater, and the acclimated process of microorganism for pulpingwaste liquor. The experiments show that:the acclimated time of anaerobic microorganism forpulping black liquor is 30 days, and that for bleaching E1 stage wastewater is 25 days; Theacclimated time of aerobic microorganism for black liquor is 20 days and that for bleaching E1stage wastewater is 25 days. After the chemical pretreatment-anaerobic microorganismaerobic microorganism-chemical aided flocculation process,the COD of black liquor decreases from 14500 mg/L to 1403. 8 mg/L and the removal rate is 90. 3%,the lignin concentrationdecreases from 6426. 6 ml/L to 191. 1 mg/L and the removal rate is 97. 0%;After the chemical pretreatment--aerobic microorganism -- biologically activated carbon process,the COD of black liquor decreases from 7405. 2 mg/L to 303. 5 mg/L and the removal rate is 96. 0%,thelignin concentration decreases from 3520 mg/L 29. 4 mg/L and the removal r
