Study on the effect of SFTWs for phosphorus removal from malodorous water
摘要
Abstract
The staged floating treatment wetlands (SFTWs) were constructed to treat malodorous water of an industrial river in Shanghai by simulating the ecological distribution of aquatic plants in the natural water, focusing on the effect of the season and temperature, plant species,pH, dissolved oxygen (DO) and other factors on the phosphorus removal rate. The results showed that the temperature changes did an obvious effect on the phosphorus removal efficiency of floating bed system where a positive correlation was in a certain temperature range. Total phosphorus (TP) and dissolved phosphorus (PO34- -P) removal rates reached 59％ and 62％ minimum respectively when the lowest temperature was 15.2 ℃. Among different species of water plants, emergent plant such as Hydrocotyle vulgaris unit removed the most phosphorus with a removal rate of 62.3％. The phosphorus removal efficiency increased when pH value rise. The DO also had an effect on phosphorus removal.关键词
