Application of dracaena deremensis 'compacta' in treatment of livestock and poultry breeding wastewater

Abstract

The invention discloses application of dracaena deremensis 'compacta' in treatment of livestock and poultry breeding wastewater, and belongs to the field of wastewater treatment. The characteristics of cold resistance, no leaf falling and no wilting in winter, and adsorption and removal of pollutants such as ammonia nitrogen, total nitrogen, total phosphorus and the like in the livestock and poultry breeding wastewater of the dracaena deremensis 'compacta' are fully utilized, and the dracaena deremensis 'compacta' is directly transplanted in environment polluted by the livestock and poultry breeding wastewater, absorbs the pollutants in the accumulated wastewater so as to purify the livestock and poultry breeding wastewater; an experiment is performed in summer, the treatment effect of the dracaena deremensis 'compacta' on the livestock and poultry breeding wastewater at a high temperature in summer is researched, the water purification effect is ensured and a new plant resource variety for the treatment of the livestock and poultry breeding wastewater is developed simultaneously, new advance and development space is brought to the deep development of treating the pollution of thelivestock and poultry breeding wastewater by using artificial wetland plants, and the dracaena deremensis 'compacta' has remarkable advantages in the aspects of operating cost, operational maintenance, treatment effect, landscape value, environmental value and economic value and the like compared with the conventional plants for purifying the 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...
