T1 – Upgrading of municipal waste water treatment plants

All WWTPs in the region of Shenyang now have to comply with the IA standard. The WWTPs in the region have been erected at different times and thus far only few of them meet the requirements. 13 of the 36 WWTPs with a total capacity of 1.41 mn. m³/d merely meet the requirements of the IB and II standards (cf. presentation Environmental Academy Shenyang from 21.03.2013). In areas with combined sewer systems WWTPs will have to temporarily take higher loads during wet weather conditions in order to minimize the combined discharge. This especially requires a corresponding increase of hydraulic capacity. The strong eutrophication of Dian lake (sometimes also called Kunming lake) mainly is a result of the discharge of untreated waste water from the city of Kunming into the lake. The first WWTP for municipal waste water commenced operation in 1990. Since then, an additional seven WWTPs treat the city’s waste water. Another six WWTPs will have been put into operation by the year 2020. The capacity will then total 1.825 mn. m³/d.

The project’s objectives include …

… the upgrading of existing municipal WWTP according to the specific Chinese demands taking into consideration the differing climatic conditions in the two regions in question.

  • Optimization of cleansing performance and cleansing efficiency based on process engineering approaches
  • Operational and energetic optimization
