摘要
石洞口污水处理厂存在雨水系统重现期标准低、初雨径流污染关注度高的问题。经比选,推荐采用海绵化改造方案,综合运用新建湿塘、雨水花园、植草沟、建筑雨水管断接、透水路面改造等措施,实现全厂雨水系统的提标控污。尾水区为改造重点,采用就地滞蓄和转输调蓄相结合的方式改造,并建设以湿塘等绿色调蓄设施为核心的海绵集成设施,通过雨天和旱天运行模式的切换,实现雨水调蓄和尾水展示的功能。通过海绵化改造,全厂可实现年径流总量控制率75%及污染物去除率55%的目标,雨水系统重现期提高至3年一遇。
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.
