摘要
通过草滤带系统处理甲鱼温室排放的富营养化养殖废水,试验研究表明,草滤带系统中水体溶解氧值很快降为0,氧化还原电位-133～-355mV,pH值偏酸,出水的pH值稍低于进水,该系统的氮素化合物易进行铵化作用,而硝化作用在较低的水平上进行。此外,该系统具有能耗低,处理效果较好,且美化环境的特点。
The paper studied grass strip system for filtering Chineseturtle pond wastewater. Dissolved oxygen concentration in treated water decreased to zero with a short time. Redox potential was between -133^-355 mV, and pH value of effluent was lower than that of the influent. It was indicated that ammonification arose easily, and nitrification arose in a lower degree. So the present system is characterized by its low energyconsuming, good treating effect, and favorable to the environment.
