污泥生态稳定化过程中渗滤液处理效能研究
Performance of Percolate Treatment in Sewage Sludge Ecological Stabilization
摘要
Abstract
A pilot scale sewage sludge ecological stabilization experiment was conducted for sludge dewatering. Reeds ( Phragmites australi ) and cattails ( Typha augustifolia ) were chosen as experiment plants.A layer of dried sludge formed on the surface of the bed in the first year. The experiment was conducted to investigate the performance of sludge layer and matrix layer dual-layer structure for percolate treatment in the second year. The sample ports set at inlet (0 cm depth), the interface of sludge and sand (50 cm depth), root layer (70 cm depth), middle matrix layer (90 cm depth) and effluent layer (110 cm depth). The results showed that percolate COD and NOx- - N concentrations increased, and NH4+ - N and TP concentrations decreased quickly after percolate flow through sludge layer. In the matrix layer,the pollutant concentrations showed a trend of decrease. The spatial variation of percolate COD and nitrogen concentrations at different ports demonstrated that the capacity of pollutant removals in reed regionwas better than that in cattail region.关键词
