Detailed Description

The technical solution of the present invention is further described below with reference to the accompanying drawings, but the scope of protection claimed is not limited to the description.

As shown in fig. 1, the sedimentation tank structure of the aquaculture wastewater treatment system of the present invention comprises a tank body 1, a sewage pipe 3 and a water purification drain pipe 4, wherein the tank body 1 is barrel-shaped, the sewage pipe 3 is located above the tank body 1, the water purification drain pipe 4 is located at the lower section of the tank body 1, an overflow pipe 2 is arranged in the tank body 1, and the overflow pipe 2 is located at one side of the tank body 1; the lower end of the overflow pipe 2 is fixedly connected with the bottom of the tank body 1, the top of the overflow pipe is provided with a filter cartridge 8, the filter cartridge 8 is movably connected with the overflow pipe 2, and filter cotton 801 is arranged in the filter cartridge 8; the lower end of the sewage pipe 3 is provided with a drainage guide plate 301, the drainage guide plate 301 inclines towards the axis direction of the sewage pipe 3, the functions of buffering, drainage and reducing the water flow speed can be achieved, and meanwhile, the drainage guide plate is back to the direction of the filter cartridge 8, so that sewage is prevented from splashing into the filter cartridge 8; a sewage discharge outlet 5 is arranged on one side of the lower section of the tank body 1, which is far away from the overflow pipe 2, and is used for discharging sediments in the tank body 1 and cleaning the bottom of the tank body 1; the outlet end of the sewage draining outlet 5 is provided with a cover body 6, the cover body 6 is movably connected with the sewage draining outlet 5, preferably in threaded connection, so that the disassembly and the assembly are convenient, and the sewage draining outlet 5 can bear the pressure when the sewage in the tank body 1 is fully loaded; a sealing gasket 7 is arranged between the cover body 6 and the sewage draining exit 5 to realize the sealing of the sewage draining exit 5 and avoid the sewage from leaking out of the sewage draining exit 5; the purified water discharge pipe 4 penetrates through the tank body 1 and is communicated with the middle lower section of the overflow pipe 2, and the purified water after sedimentation and filtration is discharged out of the sedimentation tank through the purified water discharge pipe 4 and enters a water treatment cycle.

Examples

As shown in figure 1, the tank body 1 is generally movably arranged and is positioned below a micro-filter for filtering the aquaculture wastewater, most of the aquaculture wastewater enters the next water treatment step after being filtered by the micro-filter, the aquaculture wastewater is recycled after being purified, and impurities left after being filtered by the micro-filter are left in a rotary drum of the micro-filter and are automatically and regularly washed and discharged by the micro-filter. The mixed liquid flushed down the microfiltration drum is discharged via a sewage pipe 3 into a sedimentation tank.

When sewage is discharged through the sewage pipe 2, the flow is guided by the drainage guide plate 301, so that the flow speed of liquid is reduced, and meanwhile, the liquid flows in the direction far away from the overflow pipe 2, and the sediment is prevented from splashing into the filter cylinder 8. When no liquid flows out from the sewage pipe 3, the mixed liquid is kept stand in the pool body 1, sediment such as excrement, food residue and the like filtered out from the micro-filter is settled to the bottom in the pool body 1, and the settled water is positioned on the upper layer of the mixed liquid and contains part of suspended matters and floating matters.

Along with the increase of sewage discharge of the sewage pipe 3, the mixed liquid in the pool body 1 gradually increases, and when the mixed liquid increases to the upper section of the pool body 1 and the liquid level exceeds the filter cylinder 8 at the top end of the overflow pipe 2, the mixed liquid at the upper layer naturally flows to the filter cylinder 8. The filtering cotton 801 in the filtering cylinder 8 blocks suspended matters and floating matters in the liquid, and the filtered liquid enters the overflow pipe 2.

When the liquid level in the overflow pipe 2 reaches the position of the purified water drain pipe 4, the liquid flows out through the purified water drain pipe 4 and is converged into the water treatment system, and then the liquid enters the next water treatment cycle to be recycled.

The filter cartridge 8 at the top of the overflow pipe 8 is movably connected with the overflow pipe 2, and can be detached at regular time to wash the filter cotton 801 inside, so as to prevent the filter cotton 801 from being blocked and influencing the normal work of the sedimentation tank.

When the precipitate in the cell body 1 is close to the height of the overflow pipe 2, the cell body 1 needs to be cleaned, the cover body 6 at the drain outlet 5 at the lower section of the cell body 1 is opened, the precipitate is discharged into a container prepared in advance and is transferred to a special place for stacking, and the precipitate is suitable for being used as an organic fertilizer due to the high content of ammonia nitrogen.

The junction of the sewage draining exit 5 and the cover body 6 is cleaned so as to prevent the sealing effect of the sealing gasket 7 from being influenced by the attached precipitate, and the cover body 6 and the sewage draining exit 5 are reconnected and fixed to continue to be used.
