Convenient pollution discharge method for aquaculture pond

The invention relates to the technical field of aquatic products. A convenient pollution discharge method for an aquaculture pond comprises the following steps that firstly, a pollution suction pipeline and a hose which are sequentially connected are put into the aquaculture pond to be immersed, after water enters the pollution suction pipeline and an inner cavity of the hose, the end of the hose is sealed, the aquaculture pond is taken out, and after the aquaculture pond is put into a pollution discharge ditch, the end of the hose is opened; the liquid level of the culture pond is higher than that of the drainage ditch; 2, when the culture ponds are replaced, a water stop valve installed at the end, close to a hose, of the sewage suction pipeline is closed, and the sewage suction pipeline is taken out of one culture pond and then placed into the other culture pond; thirdly, the exhaust valve close to the water stop valve is opened, and the exhaust valve is located on the side, away from the hose, of the wate
