浓缩活性污泥回流用于中小型污水处理厂节能降耗研究

Study on Concentrated Sludge Reflow Process Used in Energy Saving and Consumption Reduction of Small and Medium-scale Wastewater Treatment Plant

通过实验研究及工程验证表明,采用浓缩活性污泥回流替代传统回流方式后,虽然污水厂处理效率略有下降,但仍能满足国家排放标准,表明在确保污水厂良性运行前提下,浓缩活性污泥回流运行措施用于中小型污水处理厂节能降耗是可行的。

The experimental study and engineering verification showed that validation concentrated sludge reflow process instead of the traditional reflow process,the wastewater treatment plant processing efficiency decreased slightly,but still be able to meet the national emission standards,and thus showed that under the premise of operation,concentrated activated sludge reflow process used in small and medium-scale wastewater treatment plant is feasible.
