The Component and Characteristic Analysis of Organic Matters in Inflow Water of one Wastewater Treatment Plant in Qingdao

Abstract:

The concentration of soluble inert organics and the mass distribution of organic matter in inflow wastewater of one wastewater treatment plant (WWTP) in Qingdao city in China were studied in this paper. The results showed that the concentration of soluble inert organics in the influent which cannot be degraded by microbe was about 20 mg/L, accounts for 2%～5% of all dissolved organic matter. The small organic molecules (<1 ku) took up the largest proportion of all organics in influent, which was about 40% of dissolved organic carbon (DOC). Moreover, the residual organic molecules after biological treatment process and coagulation sedimentation process might be transformed into disinfection by-products (DBPs) by chlorination in advanced treatment process, so the combined process of ozone and activated carbon was suggested to be used to remove the small organic molecules in inflow water in this WWTP.
