| 摘 要： | 采用混凝沉淀-水解酸化/接触氧化-臭氧曝气生物滤池工艺处理某制革厂废水,给出了工艺流程,并对处理前后的水质指标进行了分析。结果表明,最终出水COD、氨氮分别可以稳定在50 mg/L和7 mg/L以下,达到了回用标准,约67%的最终出水得到回用,减少了95.56%的COD和97.78%的氨氮排放量。在不考虑人工费及折旧的情况下,运行成本约为3.41元/t。

| Abstract: | The combination of coagulation sedimentation-hydrolysis acidification with contact oxidation-ozone biological aerated filter process is applied to treat the tannery wastewater.The process flow is shown and the water quality before and after treatment is analyzed.The result shows that the concentration of COD and ammonia nitrogen in effluent could be stabilized blew 50 mg/L and 7 mg/L,respectively.The quality of effluent meets the reuse standard.About 67% of the effluent can be reused.95.56% COD and 97.78% a... |
