Application of pokeberry root in purifying livestock and poultry breeding biogas slurry

Abstract

The invention discloses an application of pokeberry root in purifying livestock and poultry breeding biogas slurry, which belongs to the field of waste water treatment. The pokeberry roots are planted in livestock and poultry breeding biogas slurry polluted environments; and the absorbing effects of the pokeberry roots on NH4+-N, TN, TP, CODcr and other pollutants in the livestock and poultry breeding biogas slurry as well as characteristics of the pokeberry roots, like vigorous vitality, capability of being directly planted, no need of special management and perennation, are sufficiently utilized so that the livestock and poultry breeding biogas slurry pollution problem is permanently solved. The application of pokeberry root in purifying the livestock and poultry breeding biogas slurry, disclosed by the invention, has the advantages of less investment, low operation cost, good effect, simplicity and easiness in operation and capability of avoiding secondary pollution while the purifying effect of a constructed wetland system in winter is ensured. The harvested pokeberry roots have effects of eliminating phlegm, relieving cough, relieving asthma, resisting bacterial, resisting virus and the like. The waste water is treated by using the pokeberry roots so that environment protection and landscape construction are combined with each other, the sustainable development idea of taking sewage treatment, ecological restoration, landscape construction and economic benefit into consideration is reflected and characteristic of combined theoretical research and application research is obtained.

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
