无剩余污泥A／O生物接触氧化法

Ａ／Ｏ系统在７０年代开发以来，广泛应用于城市污水处理，它具有同时去除废水中碳、氨、磷的特点。１９８５年上海石化．总厂涤纶厂首先将Ａ／Ｏ法用于石化行业废水处理中，并经过实践总结出一套完整的无剩余污泥Ａ／Ｏ生物接触氧化法处理流程。本流程操作管理方便，耐冲击，氮、磷、ＣＯＤ的去除率高、能耗低，并达到了无剩余污泥。

A/O Bio o c Contact Oxidation without Surplus Sludge

A/O system has been popularly used to treat domestic sewage, especially to remove the carbon, ammonia and phosphorus simultaneously. A/O was firstly used to treat petrochemical wastewater in the Fiber Factory of Shanghai Petrochemical Complex in 1985.The process of biologic contact oxidation of A/O system without surplus sludge was developed by running experience. It is easy to operate and manage, and lashproof, high removal rate of ammonia,phosphorus and COD, low power consumption, and no-surplus sludge discharge.
