Fish farming system capable of effectively discharging sewage

Abstract

The invention discloses a fish farming system capable of effectively discharging sewage and improving efficiency, and solves the problem that direct discharging of sewage in fish ponds in the prior art causes environmental pollution and dissolved oxygen in water body of the fish ponds is low. The fish farming system comprises a sewage discharging pipe, a fish pond, a paddy field, an annular purifying channel, a communicating water channel, a purifying filler, a water supply pipe and a main sewage discharging channel, one end of the main sewage discharging channel extends to the pond wall at one side of the fish pond, and the other end of the main sewage discharging channel penetrates out from the other side wall of the fish pond and is connected to the sewage discharging pipe. Each troughof the wave-shaped bottom of the fish pond is provided with a branched sewage discharging channel, and the top surface of each branched sewage discharging channel is provided with sewage inlet holes.The interior of the fish pond is provided with an inflation mechanism, and the inflation mechanism includes inflation tubes, inflation valves, inflation branch tubes, inflation branch valves and inflation ports. The fish farming system disclosed by the invention has scientific and reasonable design and is convenient to use, and the site is saved through symbiosis of fish and rice, cultivation andsupplementation of biological colonies are convenient, the purification effect is improved by 30% or more, and dissolved oxygen in water of the fish pond can be effectively increased.

Description

technical field [0001] The invention relates to a fish farming system capable of effectively discharging sewage and improving efficiency. Background technique [0002] Fish farming in ponds is a fish farming method used in most areas of China, accounting for a large proportion of freshwater fish farming. It has the characteristics of small investment, large returns, quick results, and stable production. [0003] In traditional pond fish farming, a large amount of organic matter is deposited at the bottom of the pond due to the addition of feed and fertilizer, resulting in water pollution and fish diseases are prone to occur, and these sewage are discharged directly without purification treatment, which will cause environmental pollution. But the reality is that most pond fish farmers do not have enough funds to purchase equipment to purify and treat the large amount of sewage produced, and the phenomenon of sewage discharge occurs from time to time. [0004] With the contin...
