摘要: Abstract Composting of different ratios pig manure to reed straw was studied be a natural heating technology constructed wetlands (CWs) in winter. Among the mixtures and straws ratios, pure most suitable compost material for system CWs cold climates its life expectancy about 40 days. The one-year validation test real-scale with composting as winter proved that CW can work effectively enhance pollutants removal rate water temperatures inside (15.7–21.7 °C) were higher than without (9.2–13.6 °C). mean areal load reduction TN NH3-N 1.008 g/m2/d 1.08 g/m2/d, which 120% more system.
