针对桂林北冲污水净化厂实际运行情况进行工艺优化运行研究分析，研究对象包括COD、BOD5、SS和氮、磷等营养物质，分析了A2/O工艺中的固有缺欠：硝化菌、反硝化菌和聚磷菌在有机负荷、泥龄以及碳源需求上存在矛盾和竞争，以及针对碳源问题、污泥负荷、泥龄问题、生化池停留时间对系统的除磷脱氮效率影响试验研究。试验结果表明：在碳源充足的情况下，采用低污泥负荷、长污泥龄、降低生化池停留时间等方式能提高除磷脱氮效率。

Aimed at the practical operation in sewage purifying plant of Guilin Beichong, the paper carries through the research and analysis on the technology optimization and operation. The research includes the nutriments such as COD、BOD5、SS, nitrogen and phosphorus. The paper analyzes the inherence shortcomings of A2/O technology: The nitrifying bacteria, de-nitrifying bacteria and phosphorus bacteria subsist in contradiction and competition in demand of organic load, sludge age and carbon sources. Based on the problems of carbon sources, sludge load and sludge age, the tests and researches are made on the impact of the retention period of bio-chemical pool on the system dephosphorization and denitrification efficiency. The result shows that the dephosphorization and denitrification efficiency can be increased by adopting low sludge load, long sludge age and by decreasing the retention period of bio-chemical pool.
