| 摘 要： | 以两只750ml UASB反应器分别作为酸化相和甲烷相进行农业废弃物厌氧处理的研究,两相中,都培养出了颗粒污泥。酸化相有机负荷达240kgCOD/m~3[bed]·d,HRT=1.6h,酸化率66％,COD去除率4％～8％,甲烷相有机负荷达88kgCOD/m~3[bed]·d,HRT=3.7h,COD去除率大于85％。两相COD总去除率大于90％,总有机负荷60kgCOD/m~3[bed]·d。并结合扫描电镜照片,对两相颗粒污泥的形成,菌体分布规律等进行了探讨。

| Abstract: | Two UASB reactors were used to evaluate separated-phase anaerobic treatment of a high strength wastewater. The granular sludge is well cultivated in both the methanogenic phase reactor and acidification reactor. In methenogenic phase,COD removal rate reaches 85%~90% when the organic load and HRT are at 88kg COD/m3 [bed] . d and 3. 7h respectively. In the acid phase reactor,the VFA yield coefficient reaches 66% when organic load and HHT are at 240kg COD/m3[bed] . dand 1.6h respectively. COD removal rate reaches 4%~8%. Total COD removal rate reaches 92%,the organic load and HRT are at 60kgCOD/m3[bed] . d and 5. 3h. In this study,the maximum VFA yield coefficient reaches 70. l%,when organic load was 140kgCOD/m3[bed] . d,pH5. 3~5. 5,influent COD:TA 4. 4mg/mg. The characteristics of two-phase system were investigated in granular sludge formation and microbiological aspects. |
