Abstract

Abstract

Jiangsu promulgated a new regional standard, "Emission Limits for Major Water Pollutants from Urban Sewage Treatment Plants and Key Industrial Industries in the Taihu Basin" (DB32/1072-2018) in June 2018. Urban sewage treatment plants in the Taihu Basin are facing a new round of upgrading and reconstruction. Regarding a municipal sewage treatment plant in the Taihu Basin as the research object, the whole process analysis was applied to evaluate the main problems in the actual operation of the Orbal oxidation ditch. The results showed that the rate of denitrification potential and rate of activated sludge were 8.0 and 2.24 mg NO₃^--N/(g VSS·h) respectively. Regarding the analysis of the whole process of chemical oxygen demand (COD) and total nitrogen (TN), it revealed that the lack of carbon source, low internal reflux ratio, and siltation limited the further improvement of nitrogen removal efficiency, so there was still a certain potential for nitrogen removal after the optimized operation. This paper provided a basis for the actual operation of the plant and the design of the subsequent upgrade, and also offered a reference for the similar urban sewage treatment plants that had the need for upgrade and renovation.
