码头机械保养场初期雨水的收集与处理

Collection and treatment of initial rainwater in wharf mechanical service yard

码头流动机械保养场的初期雨水中含有很多油类污染物,若不经处理直接排海将会对水体造成污染。以广州某大型集装箱码头工程为例,介绍了流动机械保养场初期雨水的收集形式和处理方案,并提出污水输送采用半自动的控制方式,有效减少了污水处理站的设计负荷。初期雨水经处理后可回收利用,有利于减轻环境污染,节约水资源。

Initial rainwater in wharf mechanical service yard carries lots of oil pollutants, and it can cause water pollution inevitably if discharged to the sea directly without treatment. Taking the engineering of a large-scale container terminal of Guangzhou as an example, the collection and treatment measures of initial rainwater in wharf mechanical service yard were introduced. It was suggested that, semi-automatic control mode should be used for sewage transport so as to reduce the design load of sewage treatment station. It was indicated that, recycling treated initial rainwater was feasible, which could reduce environmental pollution and save water resource as well.
