摘要
调查江苏省扬州市餐饮废水排放特征,开发出一种厌氧-好氧填料床联合反应器用于处理餐饮废水。通过试验确定上流式厌氧填料床水力停留时间为4h,当联合工艺的总水力停留时间为8h时,联合工艺对餐饮废水处理COD_(cr)去除率达到了90%。出水中COD_(cr)、NH_3-N、SS、磷酸盐指标达到国家一级排放标准。
The characteristics of the restaurant wastewater of Jiangsu Yangzhou city were investigated. We developed a kind of anaerobic - aerobic packed bed consociation reactor. By experiment we certained the HRT of up - flow anaerobic packed bed reactor 4h, when the total HRT of the consociation technology is 8h, the removal efficiency of CODcr, exceeded 90%. The outflow CODcr, NH3 - N, SS and IP index met with one class level of integrated wastewater discharge standard.
