| 摘 要： | 采用厌氧-缺氧-好氧-复合(A1-A2-O-M)工艺处理焦化废水,考察了外加碳源和碱源对焦化废水COD和NH4+-N脱除效果的影响。试验结果表明:外加甲醇和碳酸氢钠对焦化废水的硝化和反硝化效果影响很小;不外加碳源和碱源时,焦化废水经处理后出水的COD和NH4+-N平均质量浓度分别为125.0mg/L和1.12mg/L,分别达到《污水综合排放标准》(GB8978-1996)中的二级标准和一级标准。

| Abstract: | The anaerobic-anoxic-aerobic-hybrid biological reactor(A1-A2-O-M) was used for wastewater treatment in a coking plant.The removal effect of COD and NH4 -N was studied when carbon source and alkali source were added.The results show that the effect of denitration and nitration does not change when methanol and sodium bicarbonate are thrown in.When neither carbon source nor alkali source was added into this system,the average concentrations of the effluent COD and NH4 -N were 125.0mg/L and 1.12mg/L respectively,and they attained the class 2 and class 1 of the National Wastewater Integration Discharge Standard(GB8978-1996),respectively. |
