Abstract

Abstract Bayat J, Hashemi SH, Nikzad MF, Talakesh SMR. 2021. Necessity of water treatment to meet lake water quality goals in Chitgar Lake. Lake Reserv Manage. 37:160–169. Managing urban lake water quality to prevent algae blooms is important for tourism at Chitgar Lake, which is a shallow artificial lake created for recreation in northwest Tehran City, Iran. Its water quality is influenced by the Kan River as its water source, as well as by peripheral activities and bird excrement. This study investigates the effectiveness of different water quality management practices including restricted water intake rules and water treatment from April 2013 to April 2020 to improve the water quality of the lake in order to limit algae blooms. The nonparametric Mann–Kendall method and the Sen function were applied to decipher trends and assess impacts of the practices. Despite intake water control, the trend analysis showed that chlorophyll-a and total phosphorus had increased after the opening of the lake in 2013. However, this incremental trend was greatly reduced after commissioning a treatment plant for improving water quality. The treatment system improves the quality of diverted Kan River water during winter lake refill and is used to treat lake water during the rest of the year. The specific characteristics of the lake and the Kan River prevent achievement of target water quality without water treatment.

赤加尔湖水质指标水质处理的必要性

[摘要]Bayat J, Hashemi SH, Nikzad MF, Talakesh SMR。2021. 赤加尔湖水质指标水质处理的必要性。湖泊保护区管理。37:160-169。管理城市湖泊水质以防止藻类繁殖对奇加尔湖的旅游业很重要。奇加尔湖是伊朗德黑兰市西北部为娱乐而建造的一个浅水人工湖。其水质受以赣河为水源、周边活动和鸟类粪便的影响。本研究调查了2013年4月至2020年4月期间不同水质管理措施的有效性，包括限制取水规则和水处理，以改善湖泊水质，以限制藻类繁殖。应用非参数Mann-Kendall方法和Sen函数来解读趋势和评估实践的影响。趋势分析表明，在采水控制的情况下，2013年开湖后叶绿素-a和总磷呈上升趋势。然而，在为改善水质而启用处理厂后，这种增加趋势大大减少。该处理系统在冬季湖泊补充期间改善了改道的坎河水的质量，并在一年中的其余时间用于处理湖泊水。湖泊和坎河的特殊特性使不进行水处理无法达到目标水质。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
