Research on the Treatment of Combined Sewage with Biological Contact Oxidation+Coagulation-Sedimentation Combination Process
The sewerage system of a village in Anqing City was incomplete,illicit connections,and the phenomenon of sewage entering the river during the dry season was obvious.As a result,the river that passes through the village has turned into a black and odorous water body,which reduced the life quality of nearby residents and the stability of river ecosystem.Bypass treatment was carried out after sewerage cutoff work.Due to the shortage of land around the river,on the premise of fully utilizing the river course and not affecting flood discharge,this project built a steel structure platform on the downstream river channel to arrange bypass treatment equipment."Biological Contact Oxidation+Coagulation-Sedimentation combination process"was adopted to treat combined sewage,which had a small footprint and high processing efficiency,the effluent reached the standard of quasi surface class IV water constantly.The treated reclaimed water was returned to the upstream as ecological water replenishment,improved the self-purification ability of the river.
