水解酸化—SBR组合工艺处理焦化废水

Coking-plant wastewater treatment by anoxic-SBR process

采用水解酸化-SBR工艺处理焦化废水,进水水质为COD1 100mg／L,NH3-N210mg／L时,水解酸化4h,SBR曝气8h,搅拌3h,再曝气4h,沉降1.5h,出水COD68.2mg／L,NH3-N 51.2mg／L,去除率分别达到93.8％,75.6％.

A-SBR is applied to treat coking-plant wastewater with the influent COD1100mg/L, NH3-N210mg/L, anoxic 4h, SBR aeration 8h, mixing 3h, re-aeration 4h and setting 1.5h, the effluent is COD 68.2mg/L, NH3-N 51.2mg/L, and the removal rates up to 93.8% and 75.6% respectively.
