摘要：

To make microbial community be applied more easily in practical biotreatment engineering,three acclimation processes were carried out in lab scale. Three kinds of mixed microorganism cultures with degradability for a gas-making plant wastewater were obtained. The degradation experiments results of coal-gas wastewater indicated that different acclimation processes had obviously impacted on degradability of microbial community,and under high sludge loading rate,mixed microorganism cultureⅠ(obtained by H.S.B as bacteria source and raw wastewater as alone carbon and energy source)presented stronger degradability for coal gasification wastewater than the others. COD removal rate of mixed cultureⅠcan reach 57.6% under very low MLSS when the influent COD is 900 mg/L. Meanwhile,the results of microscopic examination showed that Protozoa,mainly epistylis and Vorticella species,were stronger activity and larger quantities in mixed cultureⅠ.
