Application of Aglaonena Commutatum in purification of livestock and poultry breeding biogas slurry

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...

Problems solved by technology

[0006] The purpose of the present invention is to provide a solution for the above-mentioned existing artificial wetland technology that can be used to purify biogas slurry of livestock and poultry because of insufficient plant species resources, low economic value, poor cold resistance, easy to die in winter, and unable to guarantee the purification effect of low temperature environment. A new plant resource that can be used to purify biogas slurry from livestock and poultry breeding
