Application of ficus tikoua in purification of livestock and poultry cultivation biogas slurries

Abstract

The invention discloses application of ficus tikoua in purification of livestock and poultry cultivation biogas slurries. The ficus tikoua is planted in an environment polluted by the livestock and poultry cultivation biogas slurries, the absorption effect of the ficus tikoua on pollution matters such as NH4+-N, TN, TP, CODcr in the livestock and poultry cultivation biogas slurries is sufficiently used, the ficus tikoua has dogged life force, can be directly planted, needs no special management, has the perennial characteristic, and can perpetually solve pollution problems of the livestock and poultry cultivation biogas slurries. The application has the advantages of being small in investment, good in effect, simple in operation, easy to apply and the like, and can guarantee winter purification effect of a wet land system. Harvested ficus tikoua can be used for medicines, the major functions of the ficus tikoua is chronic bronchitis, rheumatism physique ache, diarrhea, dysentery, mammitis, edema, abnormal menstruation, postpartum animal spirits ache, venomous snake bite and the like. The ficus tikoua is used for processing waste water, environmental protection and economic construction are combined, an operation mode of depending on government investment all the year of the traditional ecological engineering is expected to change, and the application of the ficus tikoua has profound and lasting significants.

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
