摘要
好氧和厌氧技术是常用的两种污水生物处理技术.好氧工艺在运行中存在动力能源消耗大、剩余污泥处理困难等诸多难以克服的问题.厌氧工艺靠厌氧微生物降解污水中的污染物,运行中无需曝气,动力能源消耗低,且剩余污泥产量小,运行操作简便.发展中国家在发展经济的同时也越来越注重环境的保护,厌氧技术作为低能耗的污水处理技术,在发展中国家具有广阔的应用前景.
Aerobic treatment and anaerobic treatment are widely used in wastewater treatment. The aerobic treatment has the problems which are difficult to overcome, such as energy consumption, excessive activated sludge, etc. In anaerobic treatment, anaerobic organisms are used to digest pollutants in wastewater, the energy consumption is lower due to no aeration requirement, surplus sludge output is small, and the operation is simple. Developing countries pay more attention to protect environment from pollution during their economic development. Anaerobic treatment, as a kind of low energy consumption wastewater treatment technology, has wide application prospect in developing countries.
