Application of centella asiatica in treatment of livestock and poultry breeding wastewater

Abstract

The invention discloses a method for treating livestock and poultry breeding wastewater, which comprises: planting centella asiatica in a livestock and poultry breeding wastewater polluted environment. Because the centella asiatica has the characteristics of absorbing and removing pollutants, such as total nitrogen, total phosphorus, ammonia nitrogen and the like, from the livestock and poultry breeding wastewater, the centella asiatica is planted in the livestock and poultry breeding wastewater polluted environment to absorb and remove the pollutants, such as total nitrogen, total phosphorus, ammonia nitrogen and the like, from the livestock and poultry breeding wastewater so as to fulfill the aim of purifying the livestock and poultry breeding wastewater. Because the centella asiatica has great vitality and does not need to be specially managed in the growing process thereof, the method is low in cost and low in operation fee and has a good effect and strong operability; at the same time, the centella asiatica has relatively high medicinal values, can be used as medicaments entirely and has the effects of clearing heat, promoting diuresis, dispelling swelling, detoxifying and treating acute filthy diseases, stomachache, heat diarrhea, dysentery, damp and hot jaundice, difficulty and pain in micturition, haematemesis, hemoptysis, hot eyes, swollen throat, rubella, acariasis, boils, pyogenic infections, traumatic injury and the like.

Description

technical field [0001] The invention belongs to the technical field of natural biodegradation of livestock and poultry breeding wastewater, and in particular relates to the application of centella asiatica in treating livestock and poultry breeding wastewater. 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 endangers Ecological security has become a social issue of widesp...
