Application of rheum officinale to livestock and poultry culture biogas slurry purification

Abstract

The invention discloses an application of rheum officinale to livestock and poultry culture biogas slurry purification and belongs to the field of waste water treatment. The rheum officinale is planted in livestock and poultry culture biogas slurry pollution environment, the absorption effect of the rheum officinale on NH<4+>-N, TN, TP, COD(cr) and the like in the livestock and poultry culture biogas slurry and the characteristics of tenacious vitality of the rheum officinale, direct planting capability, special management avoidance and perennial effect are sufficiently utilized, and the problem of livestock and poultry culture biogas slurry pollution is permanently solved. The investment and the operation cost are low, the effect is good, the operation is easy, the implementation is easy, and in addition, the winter purification effect of an artificial wetland system can be ensured. The harvested rheum officinale can also realize the medicine use and can be used for mainly treating symptoms such as hot junction thoracic glomus, damp and hot diarrhea and dysentery, jaundice, gonorrhoea, edema abdominal distension, postpartum stasis abdominal pain, abdominal mass accumulation, traumatic injury and the like. The rheum officinale is used for treating waste water, the environment protection and the economic construction are combined, the operation mode of the traditional ecological engineering of relying on the capital investment by government year after year is hopeful to be changed, and the significance is profound.

Description

technical field [0001] The invention relates to the field of livestock and poultry breeding biogas slurry treatment, in particular to an application of artificial wetland plants to purify livestock and poultry breeding biogas slurry. Background technique [0002] In recent years, with the rapid development of the large-scale and intensive livestock and poultry breeding industry, the environmental pollution caused by the livestock breeding industry has become increasingly serious, and its impact on rural drinking water safety, irrigation water, soil, agricultural products and air quality and rural The living environment poses a great threat. Anaerobic digestion technology has been widely used in the bioenergy development and pollution control of livestock and poultry wastewater, which can effectively suppress the primary pollution of livestock and poultry wastewater; however, the biogas slurry of many large-scale farms is directly discharged, resulting in Serious secondary p...

Problems solved by technology

[0006] The purpose of the present invention is to provide a solution for the above-mentioned existing artificial wetland technology that can be used to purify biogas slurry of livestock and poultry because of insufficient plant species resources, low economic value, poor cold resistance, easy to die in winter, and unable to guarantee the purification effect of low temperature environment. A new plant resource that can be used to purify biogas slurry from livestock and poultry breeding
