Description

Farming pond bottom sewage system

technical field

The utility model relates to the technical field of sewage discharge at the bottom of a breeding pond, in particular to a sewage discharge system at the bottom of a breeding pond.

Background technique

At present, in small-scale high-density aquaculture, due to the large-scale production of aquaculture metabolites and sediments and the rapid deterioration of water quality, and because farmers have weak awareness of environmental protection, aquaculture water and pond sediment are randomly discharged into surrounding natural waters, and aquaculture begins. The water was pumped back into the pond before. After years of accumulation, the pollution of the aquaculture water has been very serious. Such a water source seriously threatens the success rate of aquaculture. Therefore, it is necessary to carry out sewage discharge and filtration on the above-mentioned aquaculture water. One method is to perform cyclic filtration and sewage interception on the aquaculture water. This method of sewage discharge requires the use of a large area of aquaculture pond, and the use of power devices to circulate the water body. In order to intercept the sewage in the water, the cost of sewage discharge will increase. Secondly, the simpler sewage discharge method is exactly to arrange sewage discharge device at the bottom of the culture pond, and these sewage discharge devices are generally the sewage pipelines that are set at the bottom of the culture pond, that is, the bottom of the culture pond is provided with some fixed sewage pipelines. When the sewage settles to the bottom of the pond, it will fall into the sewage pipe. When the sewage needs to be discharged, as long as the sewage pipe is opened, the sewage will flow out of the breeding pond with the water flow. However, the effect of such sewage discharge is not ideal, because the water body cannot get Only the sewage near the sewage pipe will fall into the sewage pipe, and most of the other sewage will still be deposited on the bottom of the pool 3-10m away from the sewage pipe, which will still cause great pollution to the aquaculture water and affect the shrimp. The growth rate and survival rate greatly affect the benefits of breeding production. In order to remove the dirt near the sewage pipes, the main method at present is to manually enter the bottom of the pool for cleaning in addition to regularly draining the sewage pipes. The sewage discharge efficiency is low, and the sewage discharge effect is not ideal.

The patent for invention with the notification number CN103404458A discloses a method for biological regulation and cultivation of large-scale prawns, which includes the establishment of a standard high-level culture pond, comprehensive treatment of water quality, basic bait cultivation, feeding of shrimp seedlings, water quality in the high-level culture pond, etc. Environmental and disease biological regulation and other steps, the present invention provides an efficient and environmentally friendly large-scale prawn farming model, combined with the biological regulation method of beneficial bacteria and beneficial algae, the obtained prawns are larger in size, good in quality, high in yield, and easy to breed The benefit is good, and the problem of drug residues is eliminated, a new development path is provided for the shrimp farming industry, and the market development prospect is good. In this patent, the residual bait and feces collected and discharged from the bottom of the breeding pond are directly used in the cultivation of vegetables and melons through the established standard high position, so that the discharged sewage will pollute the environment. etc. belong to chemical disinfection preparations, and after use, there will be serious residues in the aquaculture water body, which will cause certain adverse effects on the aquaculture animals and the environment.
