Abstract:

Slurry collecting + adjusting pool + highly effective shallow gas floatation technology had been used at a paper-making plant in Henan Province， but the effluent did not reach the national discharge standard. On the basis of the original technology， the contact oxidation pool is added， so as to complete the optimum physical chemistry treatment + biochemical treatment process. The running results show that the effluent water meets the demands of the Standard of Pollutants Discharge for Paper Making Wastewater Treatment (GB 3544—2001).

Key words: paper making wastewater, contact oxidation, air floatation

摘要：

河南某造纸厂废水处理采用收浆+调节池+超效浅层气浮工艺，出水不达标。在原有工艺的基础上增加接触 氧化池，完善了物化处理＋生化处理的工艺流程。运行结果表明：用该工艺处理造纸废水，其出水水质达到《造纸工业水 污染物排放标准》(GB 3544—2001)中的要求。
