Abstract
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...
Examples
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...
