A Constructed Wetland System for Contaminated River Bypass Restoration
A constructed wetland system and bypass technology, applied in water/sewage multi-stage treatment, water/sludge/sewage treatment, climate change adaptation, etc., can solve the problem that nitrate lacks denitrification electron donors, cannot be completely removed, etc. problems, to achieve the effect of ensuring the quality of effluent water, reducing the concentration and reducing consumption

Embodiment 1
[0027] Such as figure 1 with figure 2 As shown, the contaminated river bypass repair constructed wetland system of the present invention includes an ammonia nitrogen nitrification zone 1, a solid carbon source denitrification zone 2, a deep purification zone 3, a siphon drainage system 4, and a control system, which are sequentially connected.
[0028] The ammonia nitrogen nitrification zone includes a first matrix zone and a first drainage zone. The first matrix zone is composed of a lower first water collecting layer 5 and an upper zeolite layer 6, and a first water collecting pipe 7 is arranged in the first water collecting layer 5 , The water outlet is arranged in the lower part of the first drainage area, a water distribution pipe 8 is arranged in the zeolite layer 6, and the water inlet end of the water distribution pipe 8 is connected to the outside. The solid carbon source denitrification zone 2 includes a second substrate zone and a second drainage zone. The second subs...
Embodiment 2
[0041] Such as figure 1 with figure 2 As shown, the contaminated river bypass repair constructed wetland system of the present invention includes an ammonia nitrogen nitrification zone 1, a solid carbon source denitrification zone 2, a deep purification zone 3, a siphon drainage system 4, and a control system, which are sequentially connected.
[0042] The ammonia nitrogen nitrification zone includes a first matrix zone and a first drainage zone. The first matrix zone is composed of a lower first water collecting layer 5 and an upper zeolite layer 6, and a first water collecting pipe 7 is arranged in the first water collecting layer 5 , The water outlet is arranged in the lower part of the first drainage area, a water distribution pipe 8 is arranged in the zeolite layer 6, and the water inlet end of the water distribution pipe 8 is connected to the outside. The solid carbon source denitrification zone 2 includes a second substrate zone and a second drainage zone. The second subs...
Embodiment 3
[0050] The difference from Example 2 is: the height of the zeolite layer 6 is 50 cm, and it is filled with zeolite with a particle size of 5-10 mm; the water distribution pipe 8 is set at a position 2 cm below the surface of the zeolite layer 6; the solid carbon source filling layer 10 is filled with solids The carbon source is thermoplastic biodegradable polyester with poor biodegradability, which is a mixture of polylactic acid, polybutylene succinate, and polycarbonate, with a filling height of 40cm; thermoplastic biodegradable polyester The particle size is 3-5mm, and the gravel with a particle size of 0.5-1cm is mixed evenly at a mass ratio of 2:1 and then filled. The volume of the pores of the solid carbon source filling layer 10 is set to be 1.2 times the volume of the first water inflow; the substrate used in the purification layer 13 is blast furnace slag with a particle size of 5-20 mm and a filling thickness of 60 cm. Others are the same as in Example 2.
