The treatment pool, so that other inoculated pools can quickly reach the cloth bacteria density required for treatment. The attachment base clamped in the twisted gap also has the same function of adjusting the density of cloth bacteria on demand. During use, the attachment base can be added or removed as needed to adjust the bacterial density, and the attachment base can also be transferred to inoculate sewage treatment bacteria. The role of rapid scale-up of water treatment.

A baffle is arranged near the middle of the foam separation tank; the side of the baffle close to the water inlet is paved with sand and gravel.

Near the water outlet in the ammonia nitrogen treatment pool, there is an ammonia nitrogen detection device that can control the three-way valve according to the ammonia nitrogen content.

The aquaculture sewage enters the solid-liquid separation tank body through the water inlet pipe, churns under the action of the gas of the aeration plate and passes through the densely pore surface of the solid-liquid separation plate. The solids in the sewage are washed away by air bubbles and leave the surface with dense pores, and the liquid water enters the inner side of the solid-liquid separation plate through the dense pores on the surface with dense pores, and is transported to the next treatment tank through the solid-liquid separation outlet pipe. The solid waste eventually settles near the sewage pipe and is discharged through the sewage pipe. Therefore, the present invention has the advantages of small water exchange, good water treatment effect, low operating cost, low cost, good stability, high breeding density, controllable scale of ammonia nitrogen treatment on demand, and good disease control effect.
