The invention relates to a novel ecological wetland circulating water comprehensive cultivation system. The system includes a funnel-shaped fish pond, a sewage drainage well, a sewage collection tank,a sieve filter, an ecological wetland and a thermal insulation greenhouse. The funnel-shaped fish pond is formed in a soil matrix, a PE anti-permeation film is laid on the soil matrix of the slope ofthe fish pond, geotechnical cloth is laid on the portion, near the upper edge of fish pond, of the PE anti-permeation film, the conical bottom of the fish pond is provided with a fish-pond sewage discharge hole connected with the PE anti-permeation film hermetically, the fish-pond sewage discharge hole is communicated with the sewage drainage well through an underground sewage discharge pipe, twowater outlets, in the sewage drainage well, of the sewage discharge pipe are communicated with a sewage discharge valve and an overflow pipe respectively, the peak water levels of the sewage discharge valve and the overflow pipe are lower than the upper edge of the fish pond, the sewage drainage well is communicated with the sewage collection tank, the ecological wetland is communicated with thesieve filter, the other end of the ecological wetland is communicated with a sterilization pond and an oxygen aeration pond in sequence, the oxygen aeration pond is communicated with the fish pond through the circulating pump, and a hemispherical heat preservation greenhouse is built above the fish pond. The system has less land occupation and less investment, the water environment of the fish pond is excellent, there are fewer fish diseases, fish grows fast, and energy conservation, ecological protection and high efficiency are achieved.
