Abstract

The invention provides a pond industrialized cultivation waste collecting device which is simple in structure, easy to operate and popularize and high in collecting rate. A flow guide groove is communicated with a water inlet in the side wall of a collecting cylinder, and the other end of the flow guide groove is communicated with a pond. A water pumping pipe extends in the axis direction of the collecting cylinder, and an inlet of the water pumping pipe is located at the bottom of the collecting cylinder. A water outlet is formed in the side wall of the collecting cylinder. The lowest part of the water outlet is higher than the highest part of the water inlet. The water outlet is communicated with the pond through a reflux tank. A guide plate is arranged above an aerating device on the lower portion in the pond. Gas released by the aerating device moves in the direction of the flow guide groove after being guided through the guide plate, so that water passes through the flow guide groove, enters the collecting cylinder in the tangent direction of the collecting cylinder to form rotational flow, and flows back to the pond through the water outlet and the reflux tank. According to a pond industrialized cultivation waste collecting method, along with the rotational flow of the water, waste is centralized to the lower portion of the center of the collecting cylinder gradually, and a water pumping pump pumps the water containing the waste through the water pumping pipe.
