Embodiment 1
[0028] Under natural conditions, the collected flower-leaf cold water flower seedlings are directly transplanted into a rubber bucket with a height of 29cm, a bottom diameter of 26cm, and a height of 32cm. Gravel layer, 10cm thick coarse sand layer, 10cm thick (approximately 8kg) soil layer, tap water is stable for 15 days. After the plants are stabilized, the wastewater from livestock and poultry breeding is regularly irrigated, and water samples are collected and the water quality of the effluent is measured (the hydraulic retention time is set to 7 days). The amount of water in the pot test was determined by the estimation formula (1) recommended by Reed:
[0029] Q = F K - - - ( 1 )
[0030] In formula (1): Q——design waste water flow rate, m 3 / d;
[0031] F——land area occupied by constructed wetland, hm 2 ;
[0032] K—coefficient, 6.57×10 -3 ...
