Water Resource Utilization in Taiwan’s Municipalities: A Comparative Perspective

Taiwan’s administrative divisions have been changed several times throughout history.At the end of 2010,Taiwan Region(including Taiwan Island and its off-shore islands)is divided administratively into five municipalities(直轄市),three cities(市),and 14 counties(縣).And in 2014,Taoyuan County was designated a municipality because its population is over 200 million persons.With this administration division,this paper is attempted to discuss the issue of water resource utilization with a comparative perspective in the six municipalities from north to south:Taipei City(台北市),New Taipei City(新北市),Taoyuan City(桃園市),Taichung City(台中市),Tainan City(台南市),and Kaohsiung City(高雄市).Statistics of population and fresh water provision will be utilized to analyze the related issues.It is hoped that through this comparative study,the strength and limitation of each municipality in terms of water resource utilization can be illustrated and evaluated.

超超临界锅炉酸洗技术研究与应用

超超临界参数下水分子本身具有很强的氧化性,能使锅炉水冷壁管形成致密坚固的垢。以某电厂2×600 MW超超临界机组化学清洗为例,根据锅炉垢样特性,选用了3种复合有机酸,进行静态、动态酸洗模拟试验,测定了不同配方下水冷壁的腐蚀速率,并按动态试验的结果确定了酸洗方案。最终选定了由2%羟基乙酸与0.5%氟化钠组成并添加缓蚀剂的复合有机酸进行化学清洗,腐蚀速率及腐蚀量皆符合标准,清洗效果良好。
