Could you please ask about the volume of the emergency accident pool and the initial rainwater basin? Should they be fully underground? Can they be built in the wastewater station and what standards should be considered?

A questão principalmente depende da aplicação. A a função da vala de emergência é prear quando os equipamentos de tratamento da água pararem de funcionar, enquanto asáua continua a entrar na estação de tratamento. É uma cisterna de armazen de para a água que não pode ser tratada em um certo período de tempo. A básico,,,,,,,,,必须是防渗。具体大小根据上游来水量确定,当然越大越好。全全下的深度你可以随意,但有一条,必须防渗漏。这是环保检查项。至于建在哪个位置,只要是你的区域,对外界没有异味污染,没人举报你,你就可以随意建,

那事故池是不是和应急池不一样?容积大小是怎么计算的?
Reply #42019-11-03
事故池就是应急池,设置容量可以根据正常处理水量及上游的停车时间计算。比如遇有停电事故,尤其是不知道恢复时间。这就要求在最短的时间内通知上游企业停产,因为你不可能设置无限大的污水防渗池。就是相对的这些因素整合后在设置适合的容积。(供参考)。

GB50483《化工建设项目环境保护设计规范》规定了事故应急池容量的计算方法, 事故应急池容量应根据发生事故的设备容量、事故时消防用水量及可能进入应急事故水池的降水量等因素综合确定。 对一般的新建、扩建、改建和技术改造的建设项目,其应急事故水池容量应按下式计算。 V事故水池=(V+事故V消防V雨)-V3 式中:(V(事故V消防V雨))max为应急事故废水最大计算量(m3); V最大一个容量的设备(装置)或贮罐的物料贮存量(m3); V(事故V消防V雨)为在装置区或贮罐区一旦发生火灾爆炸及泄漏时的最大消防用水量,包括扑灭火灾所需用水量和保护邻近设备或贮罐(最少3个)的的喷淋水量(m3),可根据gb500116、gb52166、gb5p74等有关规定确定; V雨为发生事故时可能进入该废水收集系统的当地的最大降雨量,应根据gb5p483有关规定确定; V3为事故废水收集系统的装置或罐区围堰、防火堤内净空容量(m3)与事故废水导排管道容量(m3)之和。
