新型氧化沟工艺的运行研究

Study on the Operation Management of New Oxidation Ditch Process

通过对漳浦污水处理厂实际运行数据进行分析，探讨城镇生活污水处理厂氧化沟工艺管理参数，提高城市污水处理运营管理的能力。研究结果表明，SV30处于20～30mL／L的范围内，实际运行出水水质稳定。此时溶解氧DO应控制在2～4mg／L，MLSS应控制在2000-7000mg／L之间。

Through the data analysis of Zhangpu sewage operation of urban sewage treatment plant were explored, and treatment plant operation, the main parameters for stable the abihty of operation management was improved. Results showed that SV30 fell in the range of 20 -30 mL/L. Effluent had good water quality, as COD and ammonia nitrogen were below the discharge limit values. Dissolved oxygen （DO） should be controlled in 2 ~ 4 mg/L, and MLSS should be controlled between 2000 -7000 mg/L in the mean time.
