An experiment of advanced treatment of secondary effluent in an urban wastewater treatment plant is carried out to produce reclaimed water reused for scenic water, in which the method of combination aerobia biofilm with micro-flocculation fibre filter is used as the main treatment process. 采用纤维生物膜滤池-强化微絮凝纤维过滤的方法,对城市污水厂二级出水进行深度处理,回用于人工景观水体。
Results The rates of bacteria detection and positive rates from infected root canals were high. Anaerobia and aerobia were sensitive to different kinds of antibiotics. 结果感染根管的细菌检出率、阳性率均很高,厌氧菌、需氧菌对各种抗菌药物敏感。
