Embodiment 1

[0024] This example is the application of Heimeiren to treat livestock and poultry breeding biogas slurry. 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 internal oxygen supply capacity of the wetland system, thereby improving the purification effect of organic matter in wastewater, shale hollow bricks...

Abstract

The invention discloses an application of Aglaonena Commutatum in purification of livestock and poultry breeding biogas slurry and belongs to the field of wastewater treatment. With Aglaonena Commutatum planted in a livestock and poultry breeding biogas slurry polluted environment, polluted substances such as NH4<+>-N, TN, TP, CODcr and the like in the livestock and poultry breeding biogas slurry are absorbed by Aglaonena Commutatum. Aglaonena Commutatum has strong vitality, can be directly planted, requires no special cultivation and has a characteristic of perennation. Therefore, the pollution of livestock and poultry breeding biogas slurry can be permanently solved. The application requires less investment and low operation cost, has a good effect, is simple and easy to operate, and can guarantee a purification effect of a constructed wetland system in winter. By the utilization of Aglaonena Commutatum for wastewater treatment, environmental protection is combined with landscape construction, which embodies sustainable development concepts of sewage treatment, ecological restoration, landscape construction and economic benefit which are all taken into consideration. The application provided by the invention is characterized by the combination of theoretical research and practical application, and is of profound importance.

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...
