污水厂功能调整用于初期雨水调蓄的工程应用

Engineering Application of WWTP Function Adjustment in Storage of Initial Rainwater

为缓解初期雨水对河道水质的影响,针对现状污水厂进行功能调整,取消污水处理功能,改造为初期雨水调蓄设施.结合污水厂构筑物实际情况,综合考虑投资、工期、施工影响等因素,采用利旧方案,利用现状构筑物改造为初期雨水调蓄池,并增加相应配套设施,满足初期雨水调蓄功能,具有较高的社会经济效益,为其他工程提供参考.

In order to alleviate the influence of initial rainwater on the river water quality,aimed at the current situation,the functions of wastewater treatment plant(WWTP)are adjusted to cancel the function of sewage treatment and reconstruct to the initial rainwater storage facilities.Combined with the actual situation of the structures in WWTP,the factors of investment,construction period and construction influence are comprehensively considered.The scheme of utilizing the old structures is adopted.The current structures are utilized and reconstructed to the initial rainwater storage tank.And the corresponding supporting facilities are added to meet the function of initial rainwater storage,which has the higher social and economic benefits and provides the reference for the other projects.
