新建污水厂进厂干管不停水接驳案例实践

CONCRETE PRACTICE OF NEW PIPELINE OF SEWAGE PLANT COMBINE WITH WORKING PIPELINE

随着城市化进程的加快,城市人口不断聚集,国内大多数城市选择新建污水厂以处理渐增的生活污水。而现状污水管持续高水位运行,因此新建污水厂与现状污水管道的接驳成为一大难题;常规手段为现状污水管直接停水进行接驳,但弊端明显。以深圳市埔地吓水质净化厂(三期)进厂管道成功不停水接驳实例切入,探析如何巧妙利用现有条件与设施实现不停水接驳。

With the acceleration of the urbanization process,the urban population continues to gather,and most cities in China choose to build sewage plants to deal with the increasing domestic sewage.However,the existing sewage pipes always run at high water levels,and the connection between the new sewage plant and the existing sewage pipeline has become a big problem.The conventional method is to stop the existing sewage pipes from running,but the disadvantages are obvious.The example of the successful uninterrupted water connection of the incoming pipelines of Pu Dixia sewage treatment plant(Phase III)is analyzed,and how to make use of the existing conditions and facilities to realize the uninterrupted water connection.
