Application of berberis julianae schneid in purification of livestock and poultry breeding biogas slurry

Abstract

The present invention discloses an application of berberis julianae schneid in purification of livestock and poultry breeding biogas slurry, and belongs to the field of wastewater treatment. According to the present invention, berberis julianae schneid is planted in an environment polluted by livestock and poultry breeding biogas slurry, and absorption effects of the berberis julianae schneid on NH4<+>-N, TN, TP, CODcr and other pollutants in the livestock and poultry breeding biogas slurry, and characteristics of tenacious vitality, direct planting, no requirement of special management and perennation of the berberis julianae schneid are completely utilized so as to permanently solve the pollution problem of the livestock and poultry breeding biogas slurry. The application of the present invention has the following advantages that: the investment is low, the operation cost is low, the effect is good, the operation is simple and easy to perform, and the winter purifying effect of the artificial wetland system is ensured; the harvested berberis julianae schneid can be used for treatments of damp-heat dysentery, diarrhea, jaundice, eczema, sores ulceration, aphthae, conjunctival congestion, pharyngalgia and other syndromes; the berberis julianae schneid is adopted to treat the wastewater treatment, such that the environmental protection and the economic construction are combined, the sustainable development thoughts concurrently comprising sewage treatment, ecological restoration and economic construction are reflected, and the far-reaching significance is provided.

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
