Embodiment 1
[0050] Simulate the situation where sewage from restaurants and restaurants pours into roadside storm drains. The rectangular ring area 3 is a sewage collection area covered with a rectangular ring cover plate 12 . Sewage is engraved on the cover plate of the rectangular ring. After the sewage is quickly poured into the rectangular ring area 3, the liquid level rises to the liquid level 1. After the sewage is filtered by the filter screen 5, the impurities remain in the rectangular ring dredging bucket 10, and the sewage is discharged into the sewage system through the sewage pipe 7 and finally reaches the Sewage plant treatment and disposal isolates the sewage from flowing into the rainwater system. Rectangular ring dredging bucket 10 can regularly propose dredging.
Embodiment 2
[0052] Simulate the situation of rainwater flowing into the roadside gullies when the initial rainwater is intercepted, see Image 6. In the early stage of rainfall, the initial rainwater first collects into the rectangular ring area 3, and the liquid level continues to rise to the liquid level 1. At this time, the initial rainwater flows to the sewage treatment system through the sewage pipe 7 for treatment, and the initial rainwater, including the pollutants therein, is discarded. flow. As the rainfall increases, the liquid level gradually rises to the liquid level 2 and turns over the adjustable weir plate 9. There are multiple threaded holes at intervals of 20 cm on the weir plate, and the threaded holes cooperate with the screws embedded in the wall to realize Adjustment for different heights.
[0053] And after entering the rectangular area 4 through the water-passing square hole 6, the rainwater is discharged into the rainwater system through the rainwater pipe 8 to c...
