| 由于进水为工业废水和生活污水形成的混合型污水，导致进水有机碳源不足以及还存在好氧池污泥浓度较低等问题，致使系统脱氮除磷效率不高。所以考虑对改良式序列间歇反应器（MSBR）进行以下改进：预缺氧池和厌氧池同时进水，进水量分别为0.2Q、0.8Q；好氧池添加悬浮填料等。在相同实验条件下对比分析了常规MSBR工艺与改进型MSBR工艺对混合型污水有机物、氮、磷的去除效果。结果表明：常规MSBR的COD平均去除率为78.82%，改进型MSBR的COD平均去除率为80.35%；常规MSBR氨氮平均去除率为90.51%，改进型MSBR氨氮平均去除率为96.94%；常规MSBR总氮平均去除率为47.12%，改进型MSBR总氮平均去除率为49.45%；常规MSBR总磷平均去除率为51.50%，改进型MSBR总磷平均去除率为71.30%。由此可得出，改进型MSBR工艺提高了脱氮除磷效率。 |

| As the water into the industrial wastewater and domestic sewage to form a mixed type of sewage, there is insufficient organic carbon source and aerobic tank sludge concentration is low and so on, resulting in the system nitrogen and phosphorus removal efficiency is not high.So began to consider the conventional MSBR process to make the following improvements: pre-anoxic tank and anaerobic pool at the same time into the water, respectively, water intake 0.2Q, 0.8Q; aerobic tank to add suspended fillers.The effects of conventional MSBR process and modified MSBR process on the removal of organic, nitrogen and phosphorus were studied under the same experimental conditions. The results show: the average removal rate of COD was 78.82%, the average removal rate of COD was 80.35%, the average removal rate of ammonia was 90.51%, the average removal rate of modified MSBR was 96.94%, and the conventional MSBR the average removal rate of TN was 47.12%, the average removal rate of modified MSBR was 49.45%, the average removal rate of total MSBR was 51.50%, and the average removal rate of total MS was 71.30%. It can be concluded that the improved MSBR process improves the efficiency of nitrogen and phosphorus removal. |
