农村生活污水生物-生态组合处理技术研究
Bio-ecological combined treatment technology of rural domestic sewage in Guangxi:a case study of Guilin
摘要
Abstract
To investigate the actual effect of the bio-ecological combined treatment technology of rural domestic sewage,a combined process of regulating pond,biofilter,submersible constructed wetlands and ecological puri-fication pond was built to monitor the water quality before and after sewage treatment.Seasonal characteristics of the removal rates were analyzed and the pollutant treatment characteristics of each unit were studied.The results show that their average removal rates of COD,TN,NH3-N and TP are 87.57%,72.18%,80.98%and 74.54%respectively in summer,77.46%,57.52%,64.48%and 67.03%in winter.There are significant seasonal differences in sewage treatment results in Guilin.The biofilter in the combined system has the largest contribution to COD and NH3-N,while the constructed wetland has the largest contribution to the removal of TN and TP.Oxidation pond shows strong low-temperature stability in treatment of pollutants.The combined system shows a good performance on rural domestic sewage treatment in Guilin.Different from Guilin,the seasonal fluc-tuation of TN removal effect is large in Taihu Lake area affected by temperature and regional sewage discharge.Further promotion of the combined system should consider regional differences.关键词
