Wastewater originating from chemical industries may contain compounds that could adversely affect the treatment processes, mainly the biological process, by either toxic or inhibition effects. The objectives of this study were to evaluate practical possibilities to upgrade existing wastewater treatment facilities by operating aerobic treatment based on membrane bioreactor (MBR) technology. Three different industries were included in this study: a paper mill that operates raw solid separators followed by anaerobic treatment; a food production plant that operates oil and grease separators, chemical flocculation, and dissolved air flotation; and port fuel facilities that include gravity oil separators. In all the above cases the biological treatment was exposed to different problems, which included: (a) the possible presence of deflocculating materials such as starch and biocides, in the case of the paper mill; (b) residual hydrophobic compounds that may affect diffusion through biosolids surfaces in the food plant; and (c) organic matter characterized by low biodegradability (hydrocarbons), in the case of the fuel port facilities. The experimental work in this study indicated that biological treatment of industrial wastewater containing contaminants characterized by hydrophobicity and/or by low biodegradability could be successfully performed by MBR configuration, obtaining effluent of high quality. However, these particular types of industrial wastewater would require the adaptation of the MBR operation conditions, by lowering cell residence time and mixed liquor volatile suspended solids (MLVSS) in the bioreactor and by increasing the amounts of excess biosolids accordingly. 相似文献

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。 相似文献
