Application of bird nest fern in treatment of livestock and poultry breeding waste water

Abstract

The invention discloses application of bird nest fern in the treatment of livestock and poultry breeding waste water, belonging to the field of waste water treatment. The technical scheme is that bird nest fern is planted in an environment polluted by the livestock and poultry breeding waste water. Since that the bird nest fern can absorb pollutants in the waste water and the vital force of the bird nest fern is very vigorous, the bird nest fern can be directly transplanted, no special management is required in the whole growth process and yearly planting is not required, the bird nest fern is planted in the environment polluted by livestock and poultry breeding waste water to absorb and accumulate the pollutants in the waste water to reduce the content of the pollutants in the waste water and to purify the livestock and poultry breeding waste water. The invention has the advantages that the cost is low, the operating cost is low, the effect is good, the operation is simple and easy, the water purifying effect is ensured, a novel plant resource variety is developed for the treatment of the livestock and poultry breeding waste water, and new progress and development space are brought to the deep development of constructed wetland plants for the treatment of the pollution caused by the livestock and poultry breeding waste water.

Description

technical field [0001] The invention relates to the technical field of natural biodegradation of livestock and poultry breeding wastewater, in particular to the application of an artificial wetland plant in the treatment of livestock and poultry breeding wastewater. Background technique [0002] The pollution of livestock and poultry breeding wastewater is long-term and irreversible. [0003] 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. Endangering ecological security has become a social problem that people are generally concerned about. The manure and sewage produced by livestock and poultry farms cause serious pollution of surface water, groundwater, soil and ambient air, which directly affects people's health and normal production and life. At present, there are mainly natural biodegradation technologies (such as soil trea...
