The present invention relates to a water treatment method for raising melanian snails and, more specifically, to a water treatment method for raising melanian snails, which primarily screens stream water with a filter net, stores the screened stream water and forms a torrent or microbubbles in the stored water in order to kill or destroy microorganisms using ultrasonic waves after making the microorganisms discharge eggs or weakening adult microorganisms by applying a physical impact to the microorganisms contained in the stream water, which are natural enemies of the melanian snails. Therefore, the present invention enables stream water to be safely used as water for raising melanian snails by fundamentally removing natural enemies of the melanian snails. The water treatment method according to an embodiment of the present invention comprises: a primary screening step of introducing stream water, and filtering out and removing floating materials or debris; an external impact step of applying an impact to microorganisms contained in the stream water, which are natural enemies of the melanian snails, with a torrent, microbubbles, or the like after storing the stream water which is primarily screened out; an ultrasonic treatment step of killing adult microorganisms or destroying eggs by applying ultrasonic waves to the microorganisms going through the external impact step; and a secondary screening step of filtering out and removing adult microorganisms or eggs which are still alive after going through the ultrasonic waves treatment step. |
