Embodiment 1

[0024] The present embodiment is the application of sprinkling golden peach leaf coral to treat livestock and poultry breeding biogas slurry, 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 ...

Abstract

The invention discloses application of aucuba japonica variegates in purifying of livestock and poultry breeding biogas slurry, which belongs to the field of waste water treatment. Pink reineckea herbs are planted in pollution environments of livestock and poultry breeding biogas slurry, absorption effect of the pink reineckea herbs on NH4+-N, troponin (TN), total protein (TP), chemical oxygen demand (CODcr) and other pollutants in the livestock and poultry breeding biogas slurry and characteristics of the pink reineckea herbs of being tenacious in life force, capable of being directly planted, free of special management and perennial are made the best of so as to permanently solve the pollution problem of the livestock and poultry breeding biogas slurry. The application has the advantages of being small in investment, low in operation cost, good in effect, easy and simple to operate and capable of ensuring purifying effect of an artificial wetland system in winter. The harvested pink reineckea herbs can cure phthisis, coughing haemoptysis, chronic bronchitis, asthma, rheumatic arthritis and other symptoms. By adopting the pink reineckea herbs to treat waste water, environment protection is combined with landscape construction and economic construction, the sustainable development concept with consideration of sewage treatment, ecological restoration, landscape construction and economic benefit is reflected, and therefore the application is profound in meaning.

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...
