生物技术与污水处理 王卓钦515111910200 摘要:污水处理的生物技术已有100年的历史,生物技术有着经济、高效的特点, 并可实现无害化、资源化。近年来,生物处理技术在微污染源水的处理中也逐步 得到应用。受污染水源水经常规的混凝、沉淀及过滤工艺只能去除水中的有机物 20%30%,且有溶解性有机物存在。因此在水质工程学中采用生物处理使水中携带 的污染物质通过微生物的代谢予以转化、稳定,使之无害化。 关键词:污水处理生物处理 Abstract:The biotechnology of sewage treatment has a history of 100 years Biotechnology has the characteristics of economy and high efficiency,and can be innocuous and resourceful.In recent years,biological treatment technology in the treatment of slightly polluted water has also been gradually applied.Polluted water by conventional coagulation,sedimentation and filtration process can only remove 20%to 30%of the organic matter in the water,and the presence of dissolved organic matter. Therefore,in water quality engineering,biological treatment is adopted to make the pollutants carried in the water transformed,stable and innocuous by the metabolism of microorganisms.
