摘要
血吸虫病是一种寄生虫病 ,流行于中国长江流域 ,钉螺是该病传播的唯一中间宿主 .根据水中钉螺行为设计的无螺取水装置可避免钉螺进入灌区农田 .根据实验室的研究结果 ,成功设计了一种无螺取水装置 ,它是根据钉螺的生态水力学特性和计算水动力学 (CFD)
Schistosomiasis is a parasitic disease. They propagate in the Yangtze River valley 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 device of the new intake is based on a sound research program in which an extensive experimental study has been carried out to gain knowledge of oncomelania eco hydraulic behaviors and a detailed flow field information is obtained through CFD simulation.
