化工区混合废水的膜法处理应用实例

Application Example of Mixed Wastewater Treatment of Chemical Industrial Area by Membrane Technology

化工区混合废水一般具有多种多样、成分复杂、多数有剧毒、可生化性差、色度高、盐度高等特性。膜生物反应器技术是将膜分离技术与传统的生化处理技术相结合的一种新型、高效的污水处理方法,具有占地面积小、活性污泥浓度高、抗冲击能力强、出水水质好、剩余污泥量少等特点。通过对某化工区综合废水选用膜技术处理的实际运行情况的分析和讨论,对此类废水采用此种技术的应用给出了指导性的结论。

Mixed wastewater of chemical industrial area was generally varied, complex composition, and most were highly toxic, but poor biochemical characteristics, high chromaticity and high salinity. Membrane bioreactor technology was a new efficient wastewater treatment technology, which combined membrane separation process with traditional biochemical treatment process. This technology was special for cover an area of an area small, high activated sludge concentration, strong shock resistance, better outlet water quality and less quantity of sludge, etc. Through analyzing and discussing the practical operation of treating a mixed wastewater of chemical industrial area using membrane bioreactor, the guidance conclusions of this kind of technology was used on treating wastewater were proposed.
