In this article,wastewater sludge ecological stabilization (WWSES) was presented for sludge dewatering,mineralization,and stabilization,as well as for percolate treatment.Two years of pilot scale experimental results indicated that sludge volatile solid,triphenylteuazolium chloride (TTC)-dehydrogenase aetivity(DHA),and moisture content as indicators showed the process and degree of sludge stabilization.The observation on dewatering process showed that dried sludge reached a content of 20%-50% total solid after two years of system operation.Sludge TTC-DHA in the first year was obviously lower than that of the second year,and TTC-DHA tended to decrease with an increase in the drying time of the sludge.Total nitrogen,total phosphorus,and organic contents of sludge decreased gradually from the top to the bottom of dried sludge layer.In comparison with natural stands on stands treated with sewage sludge,individual shoot was significantly higher,and coarse protein,coarse fat,and coarse fiber contents in reed roots,stems,and leaves in the system were higher than that of wild reed,especially coarse protein contents of reed roots in the system(7.38%)were obviously higher than that of wild reeds(3.29%).
