摘要
分析了某化学工业园废水集中处理中存在的问题并对废水处理技术改造进行了探讨,化工废水集中处理技术改造中应采用Fenton氧化对高浓度废水进行预处理、粉末活性炭-生物法强化生物处理及曝气生物滤池保障出水水质。此外,必须强化对园区企业点源污染预处理设施的监管,确保企业废水达到接管标准后进入园区污水处理厂。论文最后对园区废水处理设施的长效稳定运行提出了建议。
Based on the problems existing in the wastewater concentrative treatment of a chemical industrial park, the improvement of wastewater treatment technology was discussed. Fenton oxidation process was adopted to pretreat the high concentration wastewater. The process of powered activated carbon treatment （PACT） was used to enhance biological treatment. And a biological aerated filter （BAF） was used to ensure effluent quality. The supervision on the pretreatment facilities of the enterprises in the chemical industrial park should be strengthened, in order to ensure that the effluent quality of the enterprises could meet the nozzle connection standard of the wastewater treatment plant. Finally, several suggestions on the long-acting and stable operation of wastewater treatment facilities in the chemical industrial park were put forward.
