- Abstract:
- There are some problems in Shidongkou wastewater treatment plant, such as low design standard of rainwater system return period and high concern of initial rainwater runoff pollution.After comparison, the sponge transformation scheme was recommended, and the upgrading and pollution control of the entire rainwater system was achieved by comprehensively using the newly-built wet pond, rainwater garden, grass swale, building rainwater pipe disconnection, permeable pavement reconstruction and other measures. The tail water area was the focus of the reconstruction. The combination of on-site retention and transferred storage was adopted for reconstruction, and sponge integrated facilities represented by wet ponds and other green storage facilities were built. Therefore, the function of rainwater storage and tail water display was realized by switching between the operation mode in wet weather and dry weather. After the sponge transformation, the total annual runoff volume capture rate of 75% and pollutant removal efficiency of 55% were achieved in the whole plant, and the return period was increased to 3-year return period.
