Fishery photovoltaic complementary tail water purification constructed wetland

The invention relates to the technical field of tail water treatment, in particular to a fishery photovoltaic complementary tail water purification constructed wetland. Comprising a primary purification area with a first box body, a water inlet main pipe, a water inlet branch pipe and a stirring oxygenation device, a first wetland area with a facultative microorganism part and an anaerobic microorganism part, and a second wetland area with an aerobic microorganism part and a mechanical oxygenation area. The invention aims to solve the problems of poor pertinence, poor purification effect, high cost, difficult maintenance and the like of various tail water treatment methods in the prior art, the tail water is primarily purified through water flow stirring and oxygenation treatment in the primary purification area, and the tail water is purified through cooperation of microorganism parts with different characteristics in the first humid area and the second humid area. Efficient purification of tail water is ach
