日本对水资源的精细化管理及利用

随着经济的发展、人口的增长以及城镇化的推进和都市不断的大型化，水资源的管理面临严峻的挑战．尤其在公众环保意识和环保要求较高的情况下，工业废水的回收和处理技术、农业节水技术以及家庭节水与净水技术等要求也越来越高。未来对水资源的利用必然是一个节约、环保、安全、便捷、可循环和可持续利用的模式。通过研究日本在水资源利用、精细化管理以及水利用相关技术研发方面的做法，期望为我国节能城市等的建设提供有益参考

Fine Management and Utilization of Water Resources in Japan

With the economic development, population growth, advance of urbanization and the growing scale of urban, water management is facing tough challenges. Especially in the context of high public awareness of environmental protection, the demands on industrial wastewater recycling and treatment technology, agricultural water saving technologies, and home wate aving and water purification technologies are also increasing. The future use of water resources must be a mode meeting requirements of saving, environmental protection, safety, convenience, recycling and sustainability, etc. By studying the practice of Japan in water use and management, some useful reference can be provided for the construction of energy fficient cities in China.
