Embodiment 1

[0029]Under natural conditions, the collected golden coral seedlings are directly transplanted into a rubber bucket with a height of 29cm, a bottom diameter of 26cm, and a height of 32cm. Water pipes are installed at the bottom, and gravel with a thickness of 5cm and a diameter of about 2-5cm is arranged from bottom to top. 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:

[0030] Q = F K - - - ( 1 )

[0031] In the formula: Q——design wastewater flow rate...

Abstract

The invention discloses application of aucuba japonica in treating livestock and poultry raising wastewater, which belongs to the field of wastewater treatment and adopts the technical scheme that the aucuba japonica is planted in the environment polluted by the livestock and poultry raising wastewater. By fully utilizing the cold resistance of the aucuba japonica, leaf falling resistance and withering resistance of the aucuba japonica in winter, adsorption removal property of the aucuba japonica for the pollutants in the wastewater, and the characteristic of production and reproduction by direct transplanting or cutting, the application overcomes the defect of poor sewage treatment effect on artificial wetlands in winter, prevents secondary pollution to the water body, ensures the water purification effect, simultaneously develops a new plant resource variety for the treatment of livestock and poultry raising wastewater pollution, and brings new progress and development space for the deep development of treating the livestock and poultry raising wastewater pollution through artificial wetland plants; and moreover, compared with the conventional plants for purifying the sewage, the aucuba japonica has distinct advantages in terms of running cost, operation, maintenance and treatment effect or brought economic values of landscape, environmental protection and the like.

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...
