项目摘要

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).

由UASB反应器和DHS（下流式悬挂海绵）反应器组成的发展中国家经济高效、能耗最低的污水处理系统最初由日本长冈工业大学H. Harada研究小组于1996年提出。 2002 年，根据《亚穆纳行动计划》，在印度建造了处理能力为每天 500 立方米（相当于 3,600 人）的示范规模 DHS 工厂，此后印日合作已运行六年多，以处理现有的实际规模的污水UASB 工厂废水。 UASB/DHS组合系统在1800天的不间断连续运行中，未过滤的BOD去除率和未过滤的COD去除率分别达到96%和91%。此外，该系统在病原菌去除和硝化方面表现出令人满意的性能。 UASB/DHS组合系统被证明是发展中地区一种有前途的自可持续污水处理技术，因为它具有不需要外部强制曝气、维护成本低、剩余污泥产量少、结构紧凑（占地少）等独特优势。
