平板显示产业园区事故雨污水截留设计实例

通过雨水调蓄池及事故雨污水截留池的组合使用,对成都市某平板显示产业园区进行平时雨水调蓄及事故时雨污水截留。优化设计事故雨污水截留池的平面布置,节省工程造价,缩短施工周期。平时雨污分流接入市政雨污水管道;事故时合流收集,提升至园区事故应急池,由于雨水调蓄池的调蓄作用,有效地减小了雨污水截留池的容积。对比分析在雨污水管道末端设置电动截断阀的方案,可以避免因管道埋深过深导致园区内雨污水无法接入市政雨污水管道,提升安全可靠性。

Case Study: interception of emergency rainwater and emergency wastewater in flat panel display industry

The unpolluted rainwater of a flat panel display industry in Chengdu was stored in the rainwater storage tank,while the polluted rainwater and wastewater were trapped through the interception tank. The construction cost was saved and the construction period was effectively shortened through the optimized design of interception tank. Rainwater and wastewater were usually discharged to municipal rainwater and sewerage pipes, while the polluted rainwater and wastewater were raised to the accident emergency tank. The volume of the interception tank was effectively reduced by the rainwater storage tank. Compared with the scheme of setting the electric sluice valve at the end of the pipeline, it can avoid that the rainwater and wastewater could not be discharged into the municipal pipeline because of the excessively buried pipeline, moreover, it can improve the safety and reliability of the system.
