K1 – Regional Sewage Sludge Disposal Concept

Shenyang’s 36 municipal WWTPs produce 1,280 tons of sludge with 20 % total solids per day. Beibu’s WWTP is the only plant equipped with a digester tank for anaerobic treatment. The other plants merely dewater the sludge. Shenyang does not have a central sludge treatment facility, either. Given the city’s current development, an increase of Shenyang’s waste water volume to 2.80 mn. m³/d is expected, i.e. a sludge accrual amounting to 2,000 tons per day. As the figures reveal active anticipatory planning is crucial. Before the pilot project SINOWATER was initiated, Chinese partners expressed the urgent request for German partners to propose concepts for the municipal sludge disposal in Shenyang. Sub-project K1 therefore aims to develop a sustainable sewage sludge disposal concept for the city of Shenyang based on the long-standing German experience, with particular focus to sludge treatment optimization possibilities as well as material recycling and energy reuse options.

The project’s objectives include …

  • Development of a sustainable sewage sludge disposal concept for the city of Shenyang
    • Adaptation of German expertise to the specific Chinese conditions
    • Exploration of optimization potentials with particular view to material recycling and energy reuse options
  • Recommendations on sustainable development of sewage sludge treatment and disposal in Shenyang
    • Support of Chinese planning and management concepts regarding sewage sludge disposal
    • Strategies and recommendations on legislative and normative level
