厌氧生物处理工艺的现状与发展前景

综述厌氧技术在废水处理中的应用研究现状,包括工艺技术、厌氧反应器出水的后续处理以及厌氧技术的应用前景.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具有广阔的应用前景.

Status Quo and Prospect of Anaerobic Treatment Technology

Aerobic and anaerobic techniques are two frequently used ways for sewage disposal with biological method.Aerobic technique needs more dynamic energy,and the residual sludge is hard to solve.While anaerobic technique,which depends on degradation of contaminant by anaerobes,needs less dynamical energy and less residual sludge is left.Moreover it is easy to manipulate.Developing countries start to pay more attention to the environment protection when the economy develops.Anaerobic technique has a promising future due to low energy consumption in sewage disposal.In this paper,the present applications and study on anaerobic technology in sewage disposal were reviewed,including technics and techinques,the post-treatment of water out of the anaerobic reactor,and the prospect of anaerobic technique application.
