摘　　要：研究了厌氧折流板反应器(ABR)处理制糖废水的运行特征,并通过污泥EPS测定、小瓶静态试验、扫描电镜等分析了其微生态特征。结果表明:在HRT为24 h,水温33℃,进水ρ(COD)为1 355～2 955 mg/L,反应器对COD的去除率为87%～96%,其中第1隔室抗废水的冲击最大,VFA值最高而碱度最低,分别为9.33 mmol/L和19.25 mmol/L。小瓶静态试验表明,当基质ρ(COD)为1 000 mg/L时,第1隔室的污泥对COD去除率提升最快,由35.89%提到82.08%;而当基质ρ(COD)增加到4 000 mg/L,第5隔室COD的去除率提升较快,从21.96%提到61.72%。各个隔室污泥EPS的总量是第1隔室和第3隔室较多,分别为142.99 mg/g和205.48 mg/g。第1隔室和第2隔室中以杆菌为主,第5隔室出现了单球菌与多球菌,不同隔室内厌氧微生物的分布呈现出良好的种群分布。In the paper,it was studied the operating characteristics of treating sucrose wastewater in ABR and also analyzed the characteristics of microorganism ecology by EPS detection,small bottle of static test and scanning electron microscope.The results showed that when COD in influent was 1 355 mg/L to 2 955 mg/L;water temperature was 33 ℃,HRT=24 h,the removal rate of COD was stabilized at 87%~96%.The first compartment was impacted the biggest impulsion with the highest VFA value 9.33 mmol/L and lowest alkalinity 19.25mmol/L.The results of small bottle of static test showed that the COD removal rate of the first compartment was increased from 35.89% to 82.08% when the influent COD concentration was 1000mg/L,but when the influent COD concentration was 4000mg/L,the COD removal rate of the fifth compartment had a fairly increase from 21.96% to 61.72%.The first compartment and the third compartment had the largest EPS gross amount,which was 142.99 mg/g and 205.48 mg/g,respectively.The microbe in the first compartment and the second compartment were mainly bacillus,the monococcus and the multicoccus were discovered in the fifth compartment.There was a good distribution of microbial population in different compartments.
