【Abstract】 In view of the problems existing in the wastewater treatment system of an auxiliary agent production plant such as: lack of effective pretreatment process, low processing load of biochemical pool, and so on, an upgrading and reconstruction project based on the requirement of level A grade 1 in GB 18918—2012 Discharge Standard of Pollutants for Municipal Wastewater Ttreatment Plant was carried out on the premise that the original facilities had been fully used. Through the reconstruction, the pretreatment process was consummated, the biochemical treatment was enhanced and the advanced treatment was supplemented. The background, original process, existing problems, reconstruction measures and features, and design parameters of newly increased structures were introduced.更多还原
