Embodiment 1

[0024] This embodiment is the application of Mirabilis to treating biogas slurry from livestock and poultry breeding, and the specific application method is as follows:

[0025] 1. Construction of Constructed Wetland System

[0026] The size of the wetland system is 100cm×45cm×75cm (L×W×H); it includes the water distribution pipes installed on the top of the wetland system, and the bottom of the wetland system is the water collection tank and water outlet. Gravel layer, slag layer and sand layer are laid sequentially from the sump to the top. The constructed wetland bed is characterized in that: the inside of the wetland bed is composed of wetland filling matrix and shale hollow bricks, and there is a water collection tank at the bottom of the wetland system to collect waste water treated by the wetland system.

[0027] In order to enhance the oxygen supply capacity inside the wetland system, thereby improving the purification effect of organic matter in wastewater, shale hol...

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...
