| 中文摘要 |
| 研究中等负荷有较高去除率的潜流型人工湿地污水处理系统的环境状况。湿地中水体及出水溶解氧值均为0,氧化还原电位-200～-300mV之间,pH值偏酸,出水pH值稍低于进水。系统中N化合物主要为NH3-N,是NO3-N的4-10倍,NO2-N的100-200倍,说明易于进行氨化作用,而硝化作用在较低水平上进行。 |
| 英文摘要 |
| The environmental condition of the subsurface flow constructed wetlands wastewater treatment system which is in middle load and higher removal rate was researched.Dissolve oxygen concentration in treated water and effluent of wetlands equalled zero.Redox potential was between -200～-300 mV,pH value was below 7,pH value of effluent was lower that of wetlands influent.The main nitrogeneous compound in the system was ammonia nitrogen,which content was 4-10 times as many as nitrate nitrogen,100-200 times as many as nitrite nitrogen.It was indicated that ammonification arose easily,and nitrification arose in the lower degree at the system. |
