Detailed Description

The tail water of the culture pond is different from the sewage of the culture pond. The sewage of the culture pond is a seriously polluted water body containing a large amount of fish excrement and residual bait. The tail water of the culture pond is a water body containing soluble pollutants such as ammonia nitrogen, nitrite nitrogen and the like, relatively more suspended matters and more surface foam oil films, and the pollution degree is relatively light.

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings.

As shown in fig. 1, the tail water discharging and treating system of the embedded land-based circular pool of the utility model comprises a culture pool 1, a tail water discharging pipeline 2 and a tail water treating pool 6, wherein the culture pool 1 is cylindrical and the bottom is conical; tail water discharge pipe 2 arranges along the lateral wall in cylindrical pond, downwardly extending to and conical bottom combination department slant center extend to the central axis department, upwards extend to and often establish water level height department and change the level and arrange, be equipped with valve 3 and tee bend 4 at the horizontal segment, one of tee bend 4 leads to the opening and upwards arranges, and two-way connection is on the pipeline in addition, the horizontal segment extends breed 1 backward downwardly extending in pond to escape canal 5, and escape canal 5 has the passageway to connect tail water treatment pond 6. The upward opening of tee bend 4 both had been regarded as table and has been arranged route outlet, and this opening intercommunication air prevents to form siphon and takes out the trouble of dry culture pond water and take place simultaneously.

Further, the inlet of the tail water discharge pipeline 2 is arranged on the conical axis of the bottom at the position which is 5-20 cm away from the conical top.

Further, the valve 3 is disposed in front of the tee 4 in the tail water discharge pipe 2.

Preferably, the valve 3 is of a vertical inserting plate structure arranged on the tail water discharge pipeline 2, and is simple in structure and low in cost.

Preferably, the valve 3 is an electromagnetic valve, which facilitates automation.

Further, the tail water treatment tank 6 comprises a solid-liquid separation tank 7, a microorganism solidification treatment tank 8, a centralized treatment tank 9 for aquatic plants and algae, and an oxidation pond 10, and tail water passes through the tanks in sequence to complete purification treatment of the tail water.

Preferably, the solid-liquid separation tank 7 adopts a civil secondary sedimentation zone.

Preferably, the microorganism solidification treatment tank 8 is provided with a suspension brush or an air-laid cotton attached culture microorganism.

Preferably, there are two of the aquatic plant and algae ponds 9, and the two ponds are arranged in series.

Preferably, fish, mussels, submerged plants and emergent aquatic plants are bred in the oxidation pond 10.
