Once inside the diffusion zone, the mainstream continue to spread around, and drive around the fluid entrainment, the flow rate decreases. The snail density than water,[link widoczny dla zalogowanych], most of the snails will be free from sinking to the bottom of the tank, the other part of the snails will move forward with the mainstream movement, reach the raceway, the strong vortex area roundabout turn them back, also eventually lead to this part of the snail out of the mainstream,[link widoczny dla zalogowanych], sink bottom, there will never be a snail with the mainstream into the irrigation district. Most of the snails and in the pressure tank under the pressure, anaerobic conditions died after only a few in the water to climb along the piezometer, which is driven by snail survival instinct and pressure them to decrease aerobic direction (surface) to climb. Therefore,[link widoczny dla zalogowanych], if a similar arrangement in the irrigation devices can effectively prevent the snails with the water into the irrigation district. (3) The results can provide scientific basis for the schistosomiasis snail,[link widoczny dla zalogowanych], which can avoid the large area of common drugs put molluscicidal molluscicidal adverse consequences, such as environmental pollution and economic losses.
