Embodiment Construction
[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0033] Such as figure 1 As shown, the tidal flow wetland coupling electrochemical enhanced nitrogen and phosphorus removal system of the present invention includes a tidal flow constructed wetland aerobic bed 1 , anaerobic electrolytic bed 2 and a system return pump 8 .
[0034] The tidal flow artificial wetland good breeding bed 1 has wetland plants 9 planted thereon, and is connected with the water inlet pipe 5 provided with a pump. The substrate of the tidal flow artificial wetland aerobic bed 1 is zeolite, which has a strong effect on ammonia nitrogen in waste water. The adsorption performance can strengthen the adsorption capacity of the system to ammonia nitrogen during the flooding stage of the tidal flow wetland bed. At the same time, in the tidal flow wetland aerobic bed 1, there is a reoxygenation strengthening pipe 10 connected to ...
