Embodiment 1
[0032] 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:
[0033] Q = F K - - - ( 1 )
[0034] In the formula: Q——design wastewater flow rate, m 3 / d;
[0035] F——land area occupied by constructed wetland, hm 2 ;
[0036] K—coefficient, 6.57×10 -3 ....

Abstract
The invention discloses application of pilea cadierei in treating livestock and poultry breeding wastewater, belonging to wastewater treatment filed. In the invention, the characteristics that of pilea cadierei has cold resistance, does not fall leaves or wither in winter and can absorb and remove ammonia nitrogen, total nitrogen and other pollutants in livestock and poultry breeding wastewater is utilized, and the pilea cadierei is directly transplanted or inserted by cuttage in the environment of livestock and poultry breeding wastewater to absorb the pollutants of accumulated wastewater so as to purify the livestock and poultry breeding wastewater. The invention solves the problem that most of plants for purifying wastewater have poor purification effects in winter currently and also provides new types of plant resources for the treatment of livestock and poultry breeding wastewater pollution, brings new improvement and development space for the treatment of livestock and poultry breeding wastewater pollution by artificial wetland plants, and achieves obvious advantages in operation cost, operation maintenance, treatment effect, as well as brought economical benefits in landscape, environmental protection and medical application, compared with traditional plants for purifying wastewater.
Description
technical field [0001] The invention relates to the technical field of natural biodegradation of wastewater from livestock and poultry breeding, in particular to the application of artificial wetland plants in treating wastewater from livestock and poultry breeding. Background technique [0002] The pollution of livestock and poultry breeding wastewater is long-term and irreversible. Its pollution is characterized by high suspended solids, high organic matter and high ammonia nitrogen, strong biodegradability and strong odor. [0003] The livestock and poultry industry is an important part of my country's agriculture and rural economy, and it is also one of the main causes of non-point source pollution in my country's rural areas. The environmental pollution caused by the vigorous development of the livestock and poultry industry is becoming more and more serious, which not only affects economic development, but also Endangering ecological security has become a social issue o...
