Embodiment 1

[0024] The present embodiment is the application of Dieffenbachia for processing 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), including the water distribution pipe set at the top of the wetland system, and the bottom of the wetland system is the water collecting tank and the water outlet. The gravel layer, the slag layer and the sand layer are laid sequentially from the sump to the top. The constructed wetland bed is characterized in that: the interior of the wetland bed is composed of a wetland filling matrix and shale hollow bricks, and there is a water collecting tank at the bottom of the wetland system to collect the wastewater treated by the wetland system.

[0027] In order to enhance the internal oxygen supply capacity of the wetland system and thereby improve the purification effect of wastewater...

Abstract

The invention discloses the application of dieffenbachia picta lodd in the treatment of livestock and poultry raising biogas slurry, and belongs to the field of wastewater treatment. The dieffenbachia picta lodd is planted to an environment polluted by the livestock and poultry raising biogas slurry, and by fully utilizing the absorption effect of the dieffenbachia picta lodd on pollutants such as ammonia nitrogen (NH4+-N), total nitrogen (TN), total phosphorus (TP), chemical oxygen demand with potassium chromate (CODcr), and the like in the livestock and poultry raising biogas slurry, and the characteristics of indomitable vitality, direct planting, no need for special management and perenniality of the dieffenbachia picta lodd, the pollution problem of the livestock and poultry raising biogas slurry is permanently solved. The application has the advantages of small investment, low running cost and good effect, is simple and easy to operate and can guarantee the purification effect of a constructed wetland system in winter. The harvested dieffenbachia picta lodd can be used for curing diseases such as traumatic injuries, incised wounds, sudden contusions and sprains, furuncles, erysipelas, ulcers, and the like. By utilizing the dieffenbachia picta lodd to treat the wastewater, environmental protection is combined with landscape construction and economic construction, and the sustainable development thought of giving consideration to sewage treatment, ecological restoration, landscape construction and economic benefits is reflected, so that the application has profound significance.

Description

technical field [0001] The invention relates to the field of biogas slurry treatment for livestock and poultry breeding, in particular to the application of an artificial wetland plant for purifying biogas slurry for livestock and poultry breeding. Background technique [0002] In recent years, with the rapid development of the large-scale and intensive livestock and poultry breeding industry, the environmental pollution brought by the livestock and poultry breeding industry has become increasingly serious, which has a negative impact on the safety of rural drinking water, irrigation water, soil, agricultural products and air quality and rural areas. Human settlements pose a great threat. Anaerobic digestion technology has been widely used in the development of bioenergy and pollution control of livestock and poultry breeding wastewater, which can effectively inhibit the primary pollution of livestock and poultry breeding wastewater; but the direct discharge of biogas slurry...
