The invention discloses the application of dieffenbachia picta lodd in the treatment of
livestock and poultry raising
biogas slurry, and belongs to the field of
wastewater treatment. The dieffenbachia picta lodd is planted to an environment polluted by the
livestock and poultry raising
biogas slurry, and by fully utilizing the
absorption effect of the dieffenbachia picta lodd on pollutants such as
ammonia nitrogen (NH4+-N),
total nitrogen (TN),
total phosphorus (TP),
chemical oxygen demand with
potassium chromate (CODcr), and the like in the
livestock and poultry raising
biogas slurry, and the characteristics of indomitable
vitality, direct planting, no need for special management and perenniality of the dieffenbachia picta lodd, the
pollution problem of the livestock and poultry raising biogas slurry is permanently solved. The application has the advantages of small investment, low running cost and good effect, is simple and easy to operate and can guarantee the purification effect of a
constructed wetland system in winter. The harvested dieffenbachia picta lodd can be used for
curing diseases such as traumatic injuries, incised wounds, sudden contusions and sprains, furuncles,
erysipelas, ulcers, and the like. By utilizing the dieffenbachia picta lodd to treat the
wastewater,
environmental protection is combined with landscape construction and economic construction, and the
sustainable development thought of giving consideration to
sewage treatment, ecological restoration, landscape construction and
economic benefits is reflected, so that the application has profound significance.
