| Abstract: | The treatment capacity of the first-stage project of a sewage treatment plant in Nantong,constructed in 2008,is 2×104 m3/d with a footprint of 2.85 hm2.The influent is the chemical wastewater of 5 000 m3/d from the industrial centralized zone and the comprehensive wastewater of printing and dyeing wastewater and domestic sewage of 15 000 m3/d from three towns in the north of the plant.The chemical wastewater meets the third class criteria specified in Integrated Wastewater Discharge Standard(GB 8978-1996).The problems of the current treatment process were analyzed,the treatment capacity of different units was checked,and the reconstruction scheme was proposed.After implementation of the reconstruction project the expected effect was achieved.The effluent quality meets the first level B criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002). |
