| 摘 要： | 中国石化广州石油化工厂炼油污水NH4-N含量高、COD/NH4-N比低,致使其具有经氧化沟处理后出水脱氮效果不稳定的特点,为此研制开发了一种沸石滤床。将氧化沟出水沉淀后连续导入沸石滤床(ZPB)及活性炭滤床(ACB)与陶粒滤床(CPB),控制滤速1m·s-1.运行结果表明:沸石滤床的氨氮平均去除率高于99%,COD平均去除率为24.8%,均大大高于活性炭滤床与陶粒滤床。

| Abstract: | Waste water discharged from Guangzhou Branch of China Petrochemical Corporation Limited has high concentration of ammonium and low COD/NH4-N ratio.The waste water is treated by oxidation ditches and the removal efficiency of ammonium nitrogen is unstable. A zeolite percolator bed (ZPB) was developed and used to uptake and remove the ammonium nitrogen, organic compound, turbidity, etc. The oil refinery wastewater after treated by an oxidation ditch system and settlement process was fed to the ZPB continuously. The filtering velocity was 1 m·s-1. The results showed that the ammonium nitrogen removal efficiency by ZPB was greater than 99% within the high effective period, and the averaged COD removal efficiency was about 24.8% by ZPB system. The removal of ammonium nitrogen and COD by using ZPB system was much better than those of activated charcoal bed (ACB) system and ceramisite particle bed (CPB) system. |
