缺水一直是困扰天津地区经济快速发展的因素之一,自1997年以来华北地区连续4a的干旱少雨,使滦河水系蓄水量逐年降低,这无疑给本以步履艰难的振兴天津之路雪上加霜。缺水是自然环境的客观存在,节水不仅是当前的紧迫任务,也是一项长期的用水措施,为缓解用水紧张的现况,除大力研制和使用节水器具,限制低产出用水大户的发展以外,还应重视城市污水再生回用、沿海地区苦咸水经深度处理后分质使用等水源的开发和研究工作。笔者认为后者应视为节水的根本措施,也是本地区今后发展,保障用水的必由之路。 1 天津市区、开发区水资源分布及其特点
Water shortage has always been one of the factors plaguing the rapid economic development in Tianjin. Since a continuous drought of 4 a in North China since 1997, the water volume of the Luan River water system has been reduced year by year, which undoubtedly aggravates the difficult road of rejuvenating Tianjin. . Water scarcity is an objective reality of the natural environment. Water saving is not only an urgent task at present but also a long-term water use measure. In order to ease the current situation of water shortage, in addition to vigorously developing and using water-saving appliances and limiting the large-scale consumption of low- In addition to development, attention should also be paid to the research and development of water sources such as urban wastewater reclamation and reuse and the use of brackish water in the coastal areas after deep treatment, such as quality control. The author believes that the latter should be regarded as a fundamental measure to save water and is also the only way for the development of this region and the protection of water use. 1 Tianjin City, Development Zone, the distribution of water resources and their characteristics
