A cost-effective and minimum-energy required sewage treatment system for developing countries, which consists of UASB reactor and DHS (Down-flow Hanging Sponge) reactor was originally proposed in1996by H. Harada's research group of Nagaoka University of Technology, Japan. Demonstration scale DHS plant with a treatment capacity of 500 m3per day (equivalent to3,600population) was constructed in India under Yamuna Action Plan in2002, and since then has been in operation over six years by India-Japan collaboration to treat an existing practical-scale UASB plant effluent. The UASB/DHS combined system achieved 96% and 91%, respectively for unfiltered BOD removal and unfiltered COD removal throughout non-stop continuous operation of1800days.Moreover, the system exhibited satisfactory performance in terms of pathogen removal and nitrification. The UASB/DHS combined system is proved a promising self-sustainable sewage treatment technology for developing region, since it has distinctive advantages such as no need of external forced aeration, low maintenance and less excess sludge production and compactness (less land requirement).

1996年H.日本长冈工业大学原田研究小组。2002年，根据亚穆纳行动计划，在印度建造了一个处理能力为500 m3/天（相当于3,600人）的示范规模DHS工厂，此后，印度和日本合作已运行了六年多，以处理现有的实用规模UASB工厂的污水。UASB/DHS组合系统连续运行1800 d，对未过滤的BOD和COD的去除率分别达到96%和91%，对病原菌的去除和硝化作用也表现出良好的效果。UASB/DHS组合系统具有无需外加强制曝气、运行维护费用低、剩余污泥产量少、占地面积小等优点，是一种适合发展中地区的污水处理技术。
