摘要
通过浮床技术在稳定塘水面种植生态植物加强稳定塘的处理效果而建立生态塘。试验中得出该生态塘对高浓度生活污水具有很好的处理效果,其对CODCr,NH4+-N,TN和TP均能体现出较高的去除水平,去除率可分别达到55%,70%,80%和75%以上,即使在梅雨季节,水力停留时间大大缩短时亦能取得很好的处理效果,在农村地区较为适用。
Ecotypic vegetable is planted via a float bed to intensify the impact of stabilization bed, which is named ecotypic bed. The bed has a good disposal effect for high concentration sewage, and it can dispose of COD,NH4^＋-N,TN and TP commendably. The disposal rate can reach 55%, 70%, 80% and 75% respectively. Even in plum rain season, when HRT is shorten greatly, the ecotypic bed also has a good effect, which is suitable for treatment of sewage in rural areas.
