摘要
采用厌氧膨胀床反应器处理含酚有机废水，在中温条件（３０℃）下达到稳定状态。温度降到１５℃，处理效率明显下降；２０℃时影响很小；２３℃时有机物去除率、沼气产率与３０℃时持平，增加回流量对提高处理效率作用不大。结果表明，该工艺在常温和低回流量条件下运行依然有效，并且可以保持较高净产能量。
An anaerobic expanded bed reactor was applied to treat artificial phenol wastewater.It operated steadily in mesophilic condition (30℃).When wastewater temperature lapsed to15℃,removal efficiency decreased obviously,Temperature influence was a little in 20℃. In 23℃ organicremoval rate and biogas producing rate were about the same as that in 30℃ Removal efficiencycould not be increased efficiently by strengthening circulatory flow. Therefore this process remainsefficient in ambient temperature and low circulatory flow,thus it can increases net productive ener-gy.
