Fish closestool

    The integrated PVC fish toilet is a kind of aquaculture equipment accessories designed to match the fish pond at the bottom of the pot. The spiral structure is more conducive to pollution collection. The PVC water outlet is directly bonded to a common PVC pipe. Easy to install.

    Fish toilet is a new type of auxiliary accessories for water treatment. Over the years. Whether it's sewage treatment or aquaculture water treatment. Pollution collection has always been a central and critical issue. Ideally, our fish pond or sump would be round. We designed the bottom of the pool into an inverted cone shape.The water outlet is arranged at the center of the circle at the bottom of the pool. In this way, the organic suspended matter slowly settles to the bottom of the pool under the action of gravity. And under the action of the whirlpool water flow, concentrated to the bottom of the circular center of the outlet pipe. It goes out through the pipes. But in many cases, due to the pool 。The depth is smaller, and the horizontal diameter is larger. Therefore. Using the driving effect of the effluent water flow, some large particles of organic suspended matter cannot be carried to the outlet. In aquaculture. The residual bait, feces and other solid suspended substances that are not eaten by fish and shrimp can not be discharged from the fish pond in time, or separated from the water body by some filtration systems, then these solid suspended substances will be further decomposed into soluble substances such as ammonia nitrogen and nitrite under the action of bacteria. Ammonia nitrogen and nitrite will pass through the gills of fish, resulting in reduced oxygen carrying capacity of fish blood.The case is mild, can lead to fish, shrimp and crab poisoning. In severe cases, it can lead to the death of fish, shrimp and crabs. It brings huge losses to aquaculture farmers. Therefore. Complete and timely separation of suspended solids from water. It is the first key link of aquaculture water purification system. And a fish toilet can collect these fish droppings at the bottom of the pool, combined with the swirling water from the pipe,Carry large particles of feces into the outlet pipe.This is the basic design of the single-row fish toilet.

    Then we came up with an improved version of the single-row fish toilet. Which is now the double-row fish toilet. The double row fish toilet has two drainage outlets. The bottom outlet is used to discharge the solid suspended solids from the bottom of the fish pond. The upper drain outlet discharges the cleaner water in the middle and upper part. After the solid suspended solids sink at the bottom of the pool, under the action of eddy currents, they concentrate at the water outlet at the center of the pool circle. We can then filter it through the fish pond circulating water filtration system, and the filtered clean water will flow back to the fish pond. This is our recirculating aquaculture system.In the case of conditions, this part of the sewage is directly discharged to the outside, without treatment. It can greatly reduce the time for solid suspended matter to stay in the water for too long, resulting in excessive ammonia nitrogen salt.Therefore, the design of the double row fish toilet is more scientific and more reasonable. We even. The water from the upper outfall can be returned directly to the pool without treatment. By increasing the vortex effect of the water flow, the solid suspended solids such as fish feces and residual bait are quickly concentrated towards the bottom outlet.The bottom drain is connected in series to the water treatment equipment such as the micro-filter. In this way, only a small part of our water passes through the circulating water filtration system, which can significantly reduce the input cost of the circulating water filtration system.
