Regeneration of P-Saturated Substrates in Constructed Wetland

Abstract:

Phosphorus removal by substrates in constructed wetland has been widely accepted as the most important way. However, as the substrates of constructed wetland will be saturated with phosphorus adsorption after the long-term treatment of sewage, the effect of phosphorus removal and adsorption by substrates is limited. To improve phosphorus retention ability of substrates and extend the lifetime of full-scale constructed wetland system, this paper systematically summarized the researches of P-saturated substrates regeneration in constructed wetland. And the concern with future research directions encompasses several major topics were also prospected in this paper.
