Description

A sewage system at the bottom of the pool

technical field

The utility model relates to a sewage discharge system at the bottom of a pond, in particular to a drainage system capable of improving the clogging of pollutants at the bottom of a fish pond, and belongs to the field of aquaculture equipment.

Background technique

The sewage system of the fish pond plays a key role in the quality of the water in the pond. During use, if the sewage is not discharged cleanly, it will cause a large amount of pollutants to gather in the center of the bottom of the pond and rot, polluting the water body and causing various Problems such as the outbreak of fish disease have seriously affected aquaculture.

Fig. 1 is the sewage discharge system of existing culture pond. As shown in Figure 1, the pond is in the shape of a pot. The water inlet is located on the side wall of the pond. The bottom of the pond has a slope of 0.5%. There is a certain height difference between the upper section and the lower mouth section, the upper and lower mouth sections, the lower mouth section is lower than the upper mouth section, and a fish blocking net is arranged at the sewage outlet, and the upper mouth section of the sewage pipe and the fish blocking net are in a mosaic relationship. Pollutants flow along the bottom of the pool to the lowest center of the bottom of the pool under the force and load of the newly influent water, flow to the sewage pipe through the fishing net, and finally flow away from the lower part of the sewage pipe. The sewage system of existing aquaculture ponds has the following problems: 1) When the water inflow in the pond is insufficient, pollutants will accumulate in the sewage pipes and cause pollutant blockage; 2) When the amount of pollutants is large, the fish blocking net will be blocked by debris and fish bodies Or when there are a lot of fish cultured in the pond, pollutants at the sewage outlet are prone to blockage; 3) If the diameter of the sewage pipe, the mesh size of the fish-blocking net, and the height difference between the upper and lower sections of the sewage pipe are unreasonable, it will affect the discharge of pollutants , forming a blockage; 4) Pollutants stay in the sewage pipes for a long time, and will expand due to chemical reactions, which will increase the difficulty of sewage discharge.

The existing patent document CN104012450A (a sewage system for fry breeding ponds, 2014.09.03) discloses a sewage discharge pipe column with multiple sewage discharge holes, a return water overflow pipe, and a screen on the sewage outlet in the center of the bottom of the pond. Set on the drain hole of the drain pipe column, a drain pipe is provided between the drain outlet and the return overflow pipe, an overflow port is provided on the upper side of the return overflow pipe, and a sewage tank is provided under the outlet of the overflow port. Since the bottom of the aquaculture pool is pot-shaped to facilitate the collection of sewage, the sewage pipe column on the sewage outlet in the center of the bottom discharges the sewage through the sewage discharge hole, and the sewage discharge hole is equipped with a screen to prevent aquaculture from entering. Sewage hole, this kind of column type multi-drainage hole structure can effectively prevent sewage from clogging the sewage hole and facilitate the discharge of sewage.

Utility model content

The purpose of this utility model is to provide a sewage system at the bottom of the pool. According to the actual situation of the fish pond, a sewage treatment pool is added at the outlet of the sewage pipeline at the bottom of the pool, which can shorten the length of the sewage pipeline and reduce the difficulty of cleaning the pipeline and maintenance costs. At the same time, a submersible pump is installed in the sewage treatment pool to take away the pollutants in the pool and avoid the blockage caused by the accumulation of pollutants. It has been proved by practice that the sewage system is easy to operate and easy to maintain, and can greatly improve the discharge of pollutants. Mobility, with considerable economic benefits and good social benefits.

The utility model is realized through the following technical solutions: a sewage discharge system at the bottom of the pool, including a sewage discharge hole arranged in the center of the bottom of the pool, a fish net is arranged at the sewage discharge hole, a sewage discharge pipeline is arranged under the sewage discharge hole, and the sewage discharge pipeline includes an upper section and a lower opening section, the lower mouth section is arranged below the upper mouth section, the fish blocking net is embedded in the upper mouth section of the sewage pipeline, and a sewage treatment tank is extended downward along the outlet of the sewage pipeline lower mouth section, and a submersible pump is arranged in the sewage treatment pool.

The utility model can be designed according to the actual situation of the farm. For example, in a farm with multiple fish ponds, only one sewage treatment pool can be set, and the outlets of the lower section of the sewage pipes of multiple fish ponds can be collected in the sewage treatment pool. At the same time, a submersible pump is installed in the bottom of the sewage treatment pool to directly pump out the pollutants in the pool, completely solving the problem of unclean sewage in the fish farming pool.

The lower mouth section of the sewage pipe is arranged obliquely, the outlet of the lower mouth section is lower than the entrance of the lower mouth section, and the inclination angle is 5-10°.

A high-pressure water pipe is buried at the bottom of the pool, and the outlet of the high-pressure water pipe corresponds to a sewage discharge hole.

The upper section of the sewage pipeline is a funnel-shaped tubular structure with a diameter at the top larger than that at the bottom. The fish-blocking net is embedded on the top of the upper section, and the lower section of the sewage pipeline is connected to the bottom of the upper section.

Compared with the prior art, the utility model has the following advantages and beneficial effects:

(1) In this utility model, a sewage treatment pool is installed at the outlet of the sewage pipeline of the breeding pond, and a submersible pump is installed in it to increase the outlet pressure of the sewage pipeline, improve the sewage discharge capacity, and avoid the method of increasing the drop between the upper and lower openings of the pipeline by raising the bottom of the pool , can shorten the length of the sewage pipeline, reduce the difficulty of pipeline cleaning and maintenance costs, and completely solve the problem of unclean sewage in fish ponds.

(2) The utility model adopts the method of inclined setting of the lower mouth section of the sewage pipe, so that the outlet of the lower mouth section is lower than the entrance of the lower mouth section, and the pollutants flowing into the lower mouth section are used to flow into the sewage treatment tank along the water flow by using the height difference. Reasonable.

(3) The utility model is equipped with a high-pressure water pipe at the bottom of the pond, which can be used when there is a lot of pollutants in the pond, the fish blocking net is blocked by sundries and fish bodies, or the number of fish cultured in the pond is large. The outlet of the high-pressure pipe and water pipe is used to flush the sewage hole to dilute the pollution substances, increasing the mobility of pollutants.

(4) In this utility model, the upper section of the sewage pipeline is arranged in a funnel shape, so that the fish blocking net is embedded in the top of the funnel shape, and at the same time, the working area of the sewage hole and the fish blocking net is widened, so that more pollutants at the bottom of the pool can be discharged from the sewage. hole drain.
