摘要

针对AAC反应器能有效处理番茄酱加工废水和剩余污泥减量化的特点，分离了AAC反应器中的好氧微生物，并通过配伍实验研究了优势微生物对番茄酱加工废水的处理性能。共分离得到29株好氧细菌，根据12 h TOC降解率初步确定了6株优势菌。通过配伍比较TOC降解率，得到了两株菌的基础组合，其TOC去除率达到85.29％，单位TOC降解率的菌体增长量为1.89。结合菌体沉降性，最终构建出含有7株菌的高效微生物菌群，单位TOC降解率的菌体增长量为0.94，单位降解率的污泥产量减少了50.26％，沉降性能明显改善，OD600值仅为0.347，出水达到了国家二级标准。

Abstract

According to the characters of aerobic-anaerobic coupled reactor (AAC) with effective treatment of wastewater and achievement of sludge reduction in tomato catsup processing

aerobic strains were isolated from the aerobic field of AAC

and 29 bacterial strains were obtained.The performances of these strains to tomato processing wastewater treatment were investigated by compatibility test.Six bacterial strains were determined as the dominant ones by TOC removal rate in 12 hours.A fundamental flora including 2 strains was constructed by comparing TOC removal rate

in which the TOC removal rate and the ratio of cell growth increment to TOC removal were 85.29% and 1.89

respectively.On this basis

an efficient flora including 7 strains was constructed by comparing the TOC removal rate

the ratio of cell growth increment to TOC removal and the settling ability.The ratio of cell growth increment to TOC removal of this efficient flora decreased to 0.94

and the ratio of sludge production to TOC removal was reduced by 50.26%.With this efficient flora

the sludge settling property improved obviously and the OD600 decreased to 0.347

and the effluent water quality met the second grade criteria of integrated wastewater discharge standard in China.
