Method and device for water feeding and water draining of rectangular cultivating pond of young panax

Abstract

The invention relates to a method and a device for water feeding and water draining of a rectangular cultivating pond of young panax. A water feeding pipe and a water draining pipe are arranged in a rectangular pond body along the diagonal direction respectively, the water feeding pipe is arranged at one corner of the rectangular pond body, and the water draining pipe is arranged at the position diagonal to the corner where the water feeding pipe is arranged, so that the path of the water flow is extended, and the residence time of the water feeding in the pond is prolonged correspondingly; aplurality of rows of swirl nozzles are arranged on the wall of the water feeding pipe along the vertical direction, each row includes three swirl nozzles facing towards three directions inside the pond, and the row of the swirl nozzles in the middle face towards the diagonal direction of the pond; the water draining pipe is of inner and outer casing pipe structure in which the water level can be adjusted, the height of the water draining port on the inner pipe can be controlled through moving the inner pipe of the water draining pipe up and down to adjust the water level in the pond. The method disclosed by the invention can effectively reduce the volume of a stagnant water area in the pond, improve the water qualiy and the survival rate as well as the growth rate of the young panax, thereby realizing the effects of separation of sewage rows, reduction of pressure of purification treatment of discharge water and secondary utilization of upper layer water draining in the pond.
