Pondering over Water Conservancy Measurement Combined with Schistosomiasis Control

摘要

In recent year,the epidemic situation of schistosomiasis has been recurring, the spreading of oncomelania is obvious, and the schistosomiasis problem is quite serious in Yangtze river basin. In such case, kinds of water conservancy measurement combined with schistosomiasis control are introduced. Considering that various measures of oncomelania interception are mainly suitable for low-head project, the reliability is poor and the management operation is with high difficulty at present, the technology of interception of oncomelania snail with hydraulic separation which is suitable for high-lift and medium-head (3meters) projects and the technology of interception of oncomelania snail with net cage that can be applied to low-head projects are proposed. According to the research, we can discover the interception of oncomelania snail with hydraulic separation oncomelania snail and the interception of oncomelania snail with net cage is efficient in intercepting oncomelania snail, and can be applied to practical projects.
