某长江港口码头初期雨水收集处理工程设计实例

An Example of Rainwater Collection and Treatment Engineering Design for A Port Wharf

某港口现有散货堆场初期雨水,未经处理直接外排至市政管网,为响应环保要求,提高环保设施管理水平,本文对某港口初期雨水收集处理进行设计,主要含初期雨水的计算、收集及达标处理,计算采用参考港口工程环境保护设计规范和室外排水规范比较采用最大值,初期雨水处置采用混凝沉淀工艺,出水达到地方《污水排入城镇下水道水质标准》。

Some existing bulk cargo yard early rain,to the municipal pipe network,the direct discharge of untreated in response to the environmental protection requirements,improve the level of environmental protection facilities management,this paper to design a port initial rainwater collection processing,mainly including the calculation of the early rain,collection and treatment,calculated with reference to port engineering environmental protection design specification and compares the maximum outdoor drainage specification,Initial rainwater treatment using coagulation precipitation process,effluent to meet the local“sewage discharged into urban sewage quality standards”.
