摘要
结合《合流制系统污水截流井设计规程》(CECS 91:97)中的计算方法,通过某一算例,分析比较了在雨天实际截流工况下,堰式、槽式、槽堰结合式三种截流井的实际截流量相对于设计截流量的增加倍数,并提出了减小该增加倍数的相关措施。同时,针对堰式污水截流井提出了计算堰高的新思路,并与原设计方法进行了比较。
Based on the calculation methods in Specification for Design of Combined Sewage Intercepting Well （CECS 91 ： 97）, the paper discussed increase multiples of actual intercepting sewage flow relative to design intercepting sewage flow for three types wells of intercepting weir well, intercepting trough well, and intercepting weir-trough well under the conditions of rain days by a hypothesis case. And relative measures of reducing these values were put forward. Meanwhile, a new design calculation method about weir height of intercepting weir well was proposed, and calculation comparisons to the method in the design specification were made.
