Pond circulating water treater and use method

Abstract

The invention discloses a pond circulating water treater, and relates to culture wastewater treatment. The pond circulating water treater mainly solves the problems that residual excrement cannot be discharged in the culture process of soil pond fish culture in a traditional culture mode, and the water quality of a culture pond is seriously polluted. The pond circulating water treater comprises an outer swirler and an inner swirler connected with the outer swirler in an inserted mode; a water inlet pipe is arranged at the upper end of the outer swirler; the water inlet pipe is respectively provided with an outer swirler water inlet tangentially flowing to the inner wall of the outer swirler and an inner swirler water inlet tangentially flowing to the inner wall of the inner swirler; the top of the outer swirler is provided with a water outlet pipe; the water outlet pipe is provided with an air inlet pipe; the bottom of the outer swirler is provided with a blow-off pipe; an outlet of the blow-off pipe is provided with an inverted U-shaped pipe; the inverted U-shaped pipe is provided with an adjusting valve; and a siphon breaking structure is arranged at the top of the inverted U-shaped pipe. The invention also discloses a method for using the pond circulating water treater. According to the pond circulating water treater, the adjusting valve is arranged on the inverted-U-shaped pipe, so that the discharge capacity can be conveniently regulated, the discharge capacity can be greatly reduced through recirculating aquaculture, and the effects of energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention relates to aquaculture water treatment, more specifically, it relates to a pond circulating water processor and its use method. Background technique [0002] The pond recirculating aquaculture system is a new type of aquaculture model that is vigorously developed and constructed in my country. It uses a series of water treatments to treat the pollutants generated in the aquaculture pond and then recycle them. The pond recirculating aquaculture system can remove residual bait fecal pollutants in the aquaculture water in real time, reduce the production of ammonia nitrogen, nitrite nitrogen and other harmful pollutants, so as to achieve the purpose of purifying the aquaculture water environment. Therefore, the recirculating aquaculture system can not only solve the problem of effective use of water resources, but also provide a stable, reliable, comfortable and high-quality growth environment for aquaculture organisms, and provide favorable...

AI Technical Summary

Problems solved by technology

However, the existing circulating water equipment has the following problems: when the aquaculture water in the soil pond is separated from the large particles by swirling, the flow of the sewage outlet at the bottom of the external cyclone cannot be adjusted and can only be discharged at a fixed flow rate

With the increase of breeding time, the content of residual bait and feces of cultured organisms in earthen ponds increases accordingly, the flow rate of the sewage outlet of the external cyclone cannot correspond to the amount of residual bait and feces in different periods, and the waste residue in some external cyclones in the middle and late stages cannot Timely discharge leads to blockage of the external cyclone, resulting in low efficiency of cyclone separation
