Embodiment 1
[0030] figure 1 It is the first embodiment of the present invention, which is a schematic diagram of the general plan of hydraulic control of a representative water plant water source constructed wetland. figure 2 with image 3 It is the partial refinement in Example 1. From figure 1 It can be seen that the source water or sewage 1 first passes through the intake interception and control system 8, and then passes through the intake gate 2, flows to the Qiantang 15, and then passes through the wetland plant bed-ditch system 9, the buffer pond 16, and the pumping station. 5. Oxygenation pond 17, one or more wetland plant bed-ditch systems 9, one or more back ponds 18, which become water plants or receiving water bodies 19.
[0031] In this embodiment, after the water flows into the front pond 15, due to the sudden expansion of the water passing area, the water flow rate is rapidly reduced, which plays a role of sedimentation and buffering. Suspended solid particles (SS) and grease ...
Embodiment 2
[0044] Figure 4 It is a schematic diagram of the water inlet interception and composite probe control of the constructed wetland. A semi-suspended enclosure 20 is set 10m in front of the intake gate 2, which is fixedly suspended in front of the water inlet to prevent water hyacinth, duckweed and a large amount of floating garbage from entering the wetland. At the same time, a composite probe monitoring box 21 is installed between the semi-suspended enclosure 20 and the intake gate 2. The composite probe function includes in-situ water level and water quality monitoring and remote signal transmission, and automatically monitors and recognizes the wetland water quality status, including water level, Water quality indicators such as turbidity, dissolved oxygen, and ammonia nitrogen, especially when it encounters irregular rainstorms in the river network area, a large number of hidden pollution sources are instantly washed into the river, and the water level peaks and pollutant con...
