Embodiment 1

[0029] This example is the application of auspicious grass to treat biogas slurry from livestock and poultry breeding. The specific application method is as follows:

[0030] 1. Construction of Constructed Wetland System

[0031] 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.

[0032] In order to enhance the oxygen supply capacity inside the wetland system, thereby improving the purification effect of organic matter in wastewater, shale hollow...

Abstract

The invention discloses an application of Reineckia carnea in treating a livestock breeding biogas slurry, belonging to the field of waste water treatment. According to the invention, Reineckia carnea is grown in a livestock breeding biogas slurry pollution environment, by fully utilizing the effects that the Reineckia carnea absorbs NH4+-N, TN, TP, CODcr and other pollutants in the livestock breeding biogas slurry and utilizing the characteristics of tenacious vitality, capability of being direct planted, no need of special management and perennation of the Reineckia carnea, the livestock breeding biogas slurry pollution problem can be solved permanently. The application has the advantages of low investment, low operation cost, good effect, simple and practicable operation, and can guarantee the purification effect of a constructed wetland system in winter. The harvested Reineckia carnea can treat pulmonary tuberculosis, cough, hemoptysis, chronic bronchitis, asthma, rheumatoid arthritis, etc. By using the Reineckia carnea to treat waste water, environmental protection, landscape construction and economic construction are combined, a sustainable development idea of integrating sewage treatment, ecological rehabilitation, landscape construction and economic benefits, and the importance 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...
