Enhanced removal of NH4+ in bioretention by sludge biochar

Both bioretention and sludge biochar have better effects to the removal of nitrogen and phosphorus removal in water. Combining them coulid improve the effect of bioretention on NH4+. After applying sludge biochar, the adsorption effect of filler on NH4+ was improved. When the sludge biochar was appl...

Summary:Both bioretention and sludge biochar have better effects to the removal of nitrogen and phosphorus removal in water. Combining them coulid improve the effect of bioretention on NH4+. After applying sludge biochar, the adsorption effect of filler on NH4+ was improved. When the sludge biochar was applied to the filler, on the top of the submerged area in the tank, the removal rate of NH4+ could reach 88.62%∼94.48%.
