摘要/Abstract

摘要： 为了提高城市污水的处理效率、降低运行成本，进行了复合生物反应器处理城市污水的试验研究，从曝气停留时间、有机负荷率、气水比等3个方面研究了试验运行的最佳条件和控制参数。试验结果表明，利用该工艺方法处理城市污水在有机负荷率高达2.44 kgCOD/kgMLSS·d的条件下，停留时间1.5~2 h，气水比(2.5~3)∶1，可使出水COD去除率达80%以上。该方法强化了混合液的物相传质速率。

Abstract: The authors carried out the experiment research on treatment of municipal wastewater by hybrid biological reactor in order to improve its treatment efficiency and reduce its run cost. According to the experiment, the authors brought up the optimum parameter for run from detention time, organic loading and gas water ratio three aspects. The results showed that took this method can guarantee the rate of COD degradation more than 80%, under the condition that organic loading is 2.44 kg COD/kg MLSS·d; Detention time is 1.5~2 h; The ratio of gas to water is (2.5~3)∶1. This method can intensify the phase transfer efficiency.

Key words: hybrid biological reactor, municipal wastewater, mass transfer
