- Abstract:
- The treatment scale of a wastewater treatment plant in Suzhou industrial park is 20×104 m3/d. The process consists of modified AAO, textile filter and UV disinfection process, and the effluent quality is required to meet the first level A limit specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). To meet the requirements of upgrading the effluent quality to surface water quasi class Ⅳ standard proposed by Suzhou government, the advanced treatment process of biological aerated filter (DN type and CN type), high efficiency sedimentation tank, V-type filter and UV combined with sodium hypochlorite disinfection is adopted in the upgrading project to enhance the removal of COD, NH3-N, TN, TP and SS and ensure the disinfection performance of tail water. The actual operation shows that the project is in good condition and the effluent quality stably meets the discharge standard.
