人工湿地处理污水处理厂尾水中试研究
Research on the Pilot Scale Experiment of Tail Water from a Wastewater Treatment Plant Treated by Constructed Wetlands
摘要
Abstract
The w ater from a wastew ater treatment plant in T ianjin st ill contains a large number of N and P as w el as macromole-cules w hich are hard to be degraded. The constructed w etland system is used to perform advanced treatment on the water from the w astew ater treat ment plant so that it can meet the standard of urban landscape water use. A pilot experiment is used to sim-ulat e the removal efficiency of the const ructed wetland system on different kinds of pollutants. The results showed that ( 1) the wetland system of the inoculated microorganisms has a high removal efficiency of 84. 7% on the suspended solids of tail w at er;( 2) removal of suspended solids has a great correlat ion to matrix adsorpt ion and physical precipitat ion; ( 3) the w etland syst em of the inoculated microorganisms has a good removal efficiency of 44. 8% on COD of tail water, and the addition of funct ional microbes can improve the removal abilit y on COD; ( 4) the w etland system of the inoculated m icroorganisms does not have a good removal efficiency on ammonia nitrogen and t otal nitrogen, which is about 12. 3% and 35. 5% respectively; ( 5) the addition of dissolved oxygen can contribute to the removal of ammonia nitrogen and total nitrogen; and ( 6) the w et land system of the in-oculated microorganisms has a removal efficiency of 52. 3% on total phosphorus, main relying on the matrix adsorption and physical precipitation.关键词
