[0076] Example 1
[0077] In the estuary where sewage enters, such as figure 1 As shown in the composite system for deep purification of artificial mangrove wetland, the tail water is pumped to the sedimentation tank by a water pump. The structure of the sedimentation tank is as follows figure 2 As shown, enter the image 3 The mangrove underflow constructed wetland bed shown, such as Figure 4 The oxygen-enriched wet ground bed shown, such as Figure 5 The mangrove vertical flow wetland bed shown, such as Image 6 The vertical fluid bed body inlet piping system shown, such as Figure 7 The horizontal surface flow wetland shown is deeply purified and enters the sea through a sluice.
[0078] The bottom of the sedimentation tank is 10cm above the top of the mangrove underflow constructed wetland bed. The length*width*height of the primary sedimentation tank is 300cm*200cm*500cm, and gravel (particle size 3-5cm) 250cm is placed. The sewage enters the top of the sedimentation tank, an...
