Purifying Eutrophic Wastewater from Geese Farm with Plant Floating Bed in Winter

Abstract: The goal of this study was to compare the effects of three plants (ryegrass, chicory and cress) in floating bed systems on purification of sedimentation pond wastewater (low-concentration) and biogas slurry (high-concentration) from geese farm in winter. The results showed that the floating bed with ryegrass had better removal rates on chemical oxygen demand (COD), total nitrogen (TN) and total phosphorus (TP) of low-concentration wastewater than other groups at 60 days (P<0.05), and the removal rates were 53.… Show more

“…With a sharp increase in intensification of livestock and poultry farming, China has set strict regulations on both size and location of pig farms to reduce the associated environmental pollution and achieve global sustainable development. At present, the treatment of livestock and poultry manure includes mainly physical methods [sedimentation ( 3 ), filtration ( 4 ), dry and wet separation ( 5 ), and high-temperature drying ( 6 )], chemical methods [precipitation ( 7 ), flocculation ( 8 ), and advanced oxidation processes ( 9 )], and biochemical methods [aerobic ( 10 ) and anaerobic fermentation ( 11 )]. Among these methods, anaerobic fermentation has been receiving large attention for being simple, inexpensive, and environment friendly ( 12 ).…”
