Shrimp and rice irrigation water self-purification system

Abstract

The invention discloses a shrimp and rice irrigation water self-purification system. In the prior art, standing-water shrimp culture can pollute water so as not to facilitate the healthy growth of shrimps. A purpose of the invention is to solve the problem in the prior art. The system comprises a shrimp culture pond, an anaerobic pool, a rice field, a water storage pool, a first water ditch, a second water ditch, a third water ditch, a fourth water ditch and floating aquatic plants, wherein the floating aquatic plant planting area on the water surface of the anaerobic pool accounts for 15% ofthe total water surface area of the anaerobic pool, the outlet of the first water ditch is connected to the sewage inlet of the anaerobic pool, the water depth of the anaerobic pool is 3.5-3.9 m, thewater depth of the rice field is 0.4 m, and the water depth of the water storage pool is 2.5 m. According to the invention, the shrimp pond is communicated to the rice field while the anaerobic pool and the water storage pool are arranged between the shrimp pond and the rice field, the anaerobic pool is used for decomposing algae carcasses, residual baits, excrement, shrimp shells, dead shrimps and the like so as to effectively purify water, and the water storage pool can keep water in the shrimp pond flowing at any time so as to effectively eliminate the harm of standing-water shrimp culture.

Description

technical field [0001] The invention relates to a self-purifying system for irrigation water for shrimp and rice. Background technique [0002] In the aquaculture industry, the effect of raising shrimp is the best. It grows fast, has high value, and has low bait cost. It can be stocked twice a year, and there will be income in that year. Therefore, shrimp farming occupies an important position in the whole aquaculture industry. With the continuous improvement of shrimp farming technology, the high-density intensive shrimp farming model has become the main farming method at present. [0003] The water in the existing shrimp ponds is still water. As the shrimp grows, the water quality becomes worse and worse, which can easily lead to the death of the shrimp. Due to the high density of breeding, there will be a lot of pollution during the breeding process. Deposits around the middle outfall on the bottom of the pool. These pollutants include: algae carcasses, residual bait, ...
