Application of Thalia dealbata in purifying of livestock and poultry breeding biogas slurry

Abstract

The invention discloses application of Thalia dealbata in purifying of livestock and poultry breeding biogas slurry, which belongs to the field of waste water treatment. The Thalia dealbata are planted in pollution environments of livestock and poultry breeding biogas slurry, absorption effect of phytolaccatoxin 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 Thalia dealbata 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, remarkable in economic benefit and the like, can ensure purifying effect of an artificial wetland system in winter and simultaneously can avoid secondary pollution. By adopting the Thalia dealbata the Thalia dealbata to treat waste water, environment protection is combined with landscape construction, the sustainable development concept with consideration of sewage treatment, ecological restoration, landscape construction and economic benefit is reflected, and the application has the characteristics of combining theoretical research with application research.

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
