Embodiment 1
[0032] An organic composite slag filler artificial wetland treatment system, which strengthens denitrification to treat high nitrate nitrogen polluted water bodies. The structure of the treatment system is as follows: figure 1 and figure 2 As shown, it includes a structure 1, the front and rear ends of the structure 1 are respectively provided with a water inlet pipe 2 and a water outlet pipe 3, and the inside of the structure 1 is divided into a water storage area 6, a water distribution area 7, a treatment area 8 and a water collection area from front to back. 9. The substrates in the water distribution area 7 and the water collection area 9 are pebble fillers. The treatment area 8 includes a humus layer 82 and a filler layer 81 from top to bottom. The humus layer 82 is planted with plants 83 and the filler layer 81 The inner matrix is organic composite slag filler.
[0033] The structure 1 is a cuboid structure with a ratio of length to width of 6:1. The depth of the st...
Embodiment 2
[0046] An organic composite slag filler constructed wetland treatment system, the structure of which is shown in Example 1, in which the length, width and depth of the structure are 4.5m, 0.75m and 0.6m respectively, and the planted plants are canna. The hydraulic retention time HRT=24h, the hydraulic load is 0.025m / h, the water temperature is 8.5°C, the system feed water DOC, NO 3 - - When the concentration of N is 0.88mg / L and 25.46mg / L respectively, DOC and NO are measured after flowing through the system 3 - The concentrations of -N are 0.81mg / L and 20.81mg / L respectively. 3 - The removal rate of -N was 18.27%.
Embodiment 3
[0048] An organic composite slag filler constructed wetland treatment system, the structure of which is shown in Example 1, in which the length, width and depth of the structure are 4.5m, 0.75m and 0.6m respectively, and the planting plants are Zizania. The hydraulic retention time HRT=24h, the hydraulic load is 0.025m / h, the water temperature is 8.5°C, the system feed water DOC, NO 3 - - When the concentration of N is 0.88mg / L and 25.46mg / L respectively, DOC and NO are measured after flowing through the system 3 - The concentrations of -N are 0.31mg / L and 21.81mg / L respectively. 3 - The removal rate of -N was 14.34%.
