Embodiment 1

[0030]Under natural conditions, the collected taro 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 gravels with a thickness of 5cm and a diameter of about 2-5cm are 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:

[0031] Q = F K - - - ( 1 )

[0032] In the formula: Q——design wastewater flow rate, m 3...

Abstract

The invention discloses the use of A.cucullata in the treatment of waste water from livestock and poultry cultivation, which belongs to the field of waste water treatment and adopts a technical scheme of planting A.cucullata in an environment polluted by the waste water from the livestock and poultry cultivation. In the invention, based on the cold resistance and waste water pollutant absorption performance of the A.cucullata, the A.cucullata is planted in the environment polluted by the waste water from the livestock and poultry cultivation to absorb the pollutants accumulated in the waste water; and therefore, the pollutant content of the waste water is lowered, the waste water from the livestock and poultry cultivation is purified, secondary pollution to the water is effectively prevented, a new plant resource variety is developed for treating pollution caused by the waste water from the livestock and poultry cultivation while the water purification effect is ensured, a new progress and development space are made for the further development of the artificial wet land plant treatment of the pollution caused by waste water from livestock and poultry cultivation. Thus, compared the traditional waste water purifying plants, the A.cucullata has obvious advantages in operation cost, operation maintenance, treatment effect, landscape and medicinal economic values and other economic values.

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...
