摘要
厌氧处理技术由于造价问题影响了它在低温下的应用。综述了低温下厌氧处理技术的优势及难点,低温下厌氧微生物和颗粒污泥的研究,动力学公式的推导及其参数的确定,反应器构型的影响,并特别介绍了低温下厌氧处理城市污水的研究进展。城市污水属于复杂废水,含有大量SS,用两相厌氧处理系统。即UASB+EGSB或AF+AH在13℃的低温下处理可以取得50％或70％的总COD去除率,表明城市污水低温厌氧处理是可行的。
Anaerobic wastewater treatment has become mature, but economic problems limit its application under low temperature conditions. In this paper the superiorities and difficulties of low temperature anaerobic treatment are described. The research on the growth of anaerobic microbes at low temperature and granular sludge, deducing of dynamics formulas and parameters as well as configurations of reactor, and also the advance of low temperature anaerobic sewage treatment is explained. The constituent of municipal wastewater, which contains a large amount of SS, is rather complex, but it is treatable under low temperature condition. A two-step system consisting of either up-flow anaerobic sludge bed (UASB) reactor combined with an EGSB reactor or an anaerobic filter (AF) combined with an anaerobic hybrid(AH) reactor will be operated normally treating municipal wastewater at 13℃ with total COD removal efficiency of 50% and 70% respectively. Both of them are successful.
