Application of mirabilis jalapa in purifying livestock and poultry culture biogas slurry

Abstract

The invention discloses an application of mirabilis jalapa in purifying livestock and poultry culture biogas slurry, and belongs to the field of waste water treatment. The mirabilis jalapa is planted in the livestock and poultry culture biogas slurry polluted environment; and the characteristics that the absorption action of the mirabilis jalapa on polluted substances, such as NH4<+>-N, TN (total nitrogen), TP (total phosphorus), CODcr (Chemical Oxygen Demand Cr) and the like in the livestock and poultry culture biogas slurry, the mirabilis jalapa has tenacious vitality, can be directly planted, does not need special management and is perennial are fully utilized so as to permanently solve the pollution problem of the livestock and poultry culture biogas slurry. The mirabilis jalapa has the advantages of small investment, low operation cost and good effect, is simple to operate and is easy to realize, and the winter purification effect of the artificial wetland system can be guaranteed. The harvested mirabilis jalapa can dispel the wind, invigorate the circulation of blood, and treat stranguria with turbid urine, profuse leucorrhea, pulmonary labor hematemesis, ulcer on the back, acute arthritis, pulmonary labor hemoptysis and the like. When the mirabilis jalapa is used for treating waste water, environment protection and economic construction are combined to embody the sustainable development ideas considering the sewage treatment, ecological restoration and economic construction, and the theoretical research and the practical application are combined.

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
