Novel ecological wetland circulating water comprehensive cultivation system

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a novel ecological wetland circulating water comprehensive planting system and planting method. Background technique [0002] Fish, as an important part of human protein food, its role and status are becoming more and more prominent. Most of the current farmed fish are cultured in original ponds, with large water surface, difficult water quality control, many diseases and insect pests, and difficult to control. Even if the disease is cured, various chemicals are still used. Prevention and control has a direct impact on the quality and water quality of fish and other aquatic products. Even if some of them are cultured in artificial ponds, the feces and residual bait of the fish will be directly discharged in the pond or sink to the bottom of the pond, which cannot be cleaned in time, and the residual bait will quickly rot and deteriorate. , which seriously affects the quality ...

[0002] Fish, as an important part of human protein food, its role and status are becoming more and more prominent. Most of the current farmed fish are cultured in original ponds, with large water surface, difficult water quality control, many diseases and insect pests, and difficult to control. Even if the disease is cured, various chemicals are still used. Prevention and control has a direct impact on the quality and water quality of fish and other aquatic products. Even if some of them are cultured in artificial ponds, the feces and residual bait of the fish will be directly discharged in the pond or sink to the bottom of the pond, which cannot be cleaned in time, and the residual bait will quickly rot and deteriorate. , which seriously affects the quality of pool water. The environment cannot meet the long-term suitable growth conditions for fish. At the same time, the water quality changes rapidly, and the sewage discharge is large and difficult to handle. Therefore, it is difficult to control the water quality in this fish farming method, and the water quality cannot be guaranteed; moreover, for Those areas where water resources are scarce can't meet such a large-scale water exchange, which has great limitations and is not suitable for large-scale promotion. Finally, due to the large difference in climate and temperature between the north and the south, there are also large differences in the time suitable for fish growth. Therefore, Fish cannot get a long, stable growth period
