废水治理工程设计参数标准的讨论

按照国家废水排放标准设计，建立的污水处理工程出水往不能达标，主要原因何在？运用系统可靠性理论分析可以看出，设计参数的选择对其有重要影响。要使工程出水到废水排放标准，设计参数的选择应严于标准。

Discussion of design parameter Standard for Wastewater Treatment Engineering

The discharge from wastewater treatment engineering designed and constructed by national wastewater discharge standard can not reach the standard. What's the main course? From the theoretical analysis of systematic reliabli-ty we can see the choice of design parameter have important effect. If the discharge from treatment engineering must reach the wastewater Discharge Standard, higher of design parameter should be choosed than the standard value.
