MBR在印染废水处理中的研究进展 总被引:1,自引:1,他引:0
印染废水是一种水量大、COD高、色度高、组分复杂并含有毒物的废水,采用传统生物技术处理很难达到日益提高的排放标准。膜生物反应器是一种新型高效的水处理技术,应用膜生物反应器处理印染废水有着传统生物处理技术无法比拟的优势,文章对MBR技术处理印染废水的研究概况进行了总结。为将来膜生物反应器的发展提供了参考。 相似文献

Background: The wastewater originating from the production of acrylonitrile‐butadiene‐styrene (ABS) resin is a toxic and refractory industrial wastewater. The purpose of this work is to investigate the characteristics of adsorption and biodegradation of biological activated carbon (BAC) for ABS resin wastewater. Results: More than 80% of chemical oxygen demand (COD), total organic carbon (TOC) and organic nitrogen (Org‐N) was removed after the 100th run in BAC with the help of bioregeneration, and the treatment efficiency of BAC was higher than that of adsorption and biodegradation alone. The initial Org‐N was mainly transformed into NH4+‐N, and the transform efficiency reached 65% after the 100th run. After bioregeneration, the COD and TOC removal efficiencies of BAC reactor reached 88.97% and 86.26%, respectively. The BAC had different bioregeneration efficiencies of 94.41, 64.82, 61.05 and 40.04% for 3, 3‐imminodipropiononitrile, 3, 3‐oxydipropiononitrile, α, α‐dimethyl‐benzylalcohol and acetophenone, respectively, which mainly resulted from the different polarity of the compounds. Conclusion: BAC could protect microorganisms from shock loadings of toxic, refractory and complicated ABS resin wastewater. The mechanism of the organic pollutants removal by BAC consisted of three phases including adsorption, bioregeneration and stability. © 2012 Society of Chemical Industry 相似文献

采用生物活性炭技术深度处理焦化厂生化后出水。结果表明,焦化厂生化后出水(COD为200mg/L、色度为900度)经生物活性炭处理后,COD降为46.9mg/L、色度降至25.8度,达到国家工业再生用水水质标准(COD小于60mg/L,色度小于30);并与颗粒活性炭深度处理焦化废水相比,生物活性炭法处理焦化废水COD及色度的去除率分别提高了13.4%和5.2%,且生物活性炭使用寿命是颗粒活性炭的3.3倍,生物活性炭的吨水材料费为1.4元,比颗粒活性炭低3.26元。生物活性炭法是一种有效、低成本的焦化废水深度处理方法。 相似文献
