摘要
焦油深加工废水分为高浓度废水和低浓度废水2种。高浓度废水主要污染指标为 COD、挥发酚、氨氮,对高浓度废水采取隔油、气浮、氧化等必要的预处理措施,然后与低浓度废水混合进行生化处理。可使废水各项指标达到 GB8978—1996二级排放标准。
The waste water in tar further processsing includes high- thickness and low-thickness waste water processsing. The high - thickness waste water which main pollution components are COD, volatile hydroxyhenzene and ammonium must he pre - treated by insulating oil, air floating, oxidating and other methods, then, treated by biochemical methods commingling with the low - thickness waste water. Treated In this way, the quality of waste water can reach the criterion of Ⅱ grade in GB8978？-1996.
