摘　　要：血吸虫病是长江流域最严重的寄生虫病之一。钉螺是其唯一的中间寄主，钉螺的扩散将导致血吸虫病的蔓延。控制钉螺随水流扩散就能从根本上控制血吸虫病在灌区或居民点流行。本文介绍一种新的无螺取水方法，该方法已在实验室研究中取得了成功。这种无螺取水新方法是根据钉螺的生态水力学特性的系列试验研究和流场的计算水动力学数值模拟结果得到的。Schistosomiasis is a parasitic disease mostly found in areas along Yangtze River of China. The spread of the disease is solely through a middle-agent named oncomelania so the spread of schistosomiasis by oncomelania can be controlled by properly designing water intakes which prevent oncomelania from entering the farming land or residential areas. In this paper, a successful design process is reported and a new oncomelania-free intake device is demonstrated in the laboratory. The design on the new intake is based on a sound research program in which an extensive experimental studies have been carried out to gain knowledge of oncomelania ecohydraulic behaviors and a detailed flow field information is obtained through computation fluid dynamics simulation.
