Fish cultivation pond with water purification function

Abstract

The invention discloses a fish cultivation pond with a water purification function. The fish cultivation pond comprises a cultivation pond body and is characterized in that a fixing plate is arrangedon the upper surface of the cultivation pond body, a treatment tank and a water pump are arranged on the upper surface of the fixing plate, a water inlet pipe extending into the lower portion of the right side of the cultivation pond body is communicated to the water inlet of the water pump, a water outlet pipe communicated with the top of the treatment tank is communicated to the water outlet ofthe water pump, two filtering screen plates are obliquely arranged on the inner wall of the treatment tank, gauze is adhered to the upper surface of the lower filtering screen plate, a draining mechanism is arranged on the inner wall of the bottom end of the treatment tank, and the lateral wall of the treatment tank is provided with a rectangular through hole. The fish cultivation pond has the advantages that the water treatment effect of the cultivation pond body can be increased effectively, the water quality of the cultivation pond body is increased, the normal reproduction of fresh-water fish is guaranteed, unnecessary economic loss is avoided, the cultivation pond body does not need water changing, and water resources are saved.

Description

technical field [0001] The invention relates to the technical field of freshwater fish breeding ponds, in particular to a fish breeding pond with the function of purifying water. Background technique [0002] Freshwater aquaculture refers to the use of ponds, reservoirs, lakes, rivers and other inland waters to raise and reproduce aquatic economic animals (fish, shrimp, crab, shellfish, etc.) and the production of aquatic economic plants. It is an important part of inland aquaculture. , the main object of breeding is fish, but in the freshwater fish farming industry, fry breeding has higher requirements on the water quality of the rearing pond. [0003] The water body in the freshwater fish breeding pond is easy to deteriorate after a period of time, which will affect the reproduction of freshwater fish and easily cause large economic losses. However, the existing water body treatment equipment in the freshwater fish breeding pond has a simple structure and poor treatment ef...
