某制药产业园污水处理厂提标扩容设计

以制药废水为主的某产业园污水处理厂的水量已趋饱和后,规模需从1.0万m3/d扩容至2.5万m3/d,同时出水水质标准从CODCr≤150 mg/L提高至≤100 mg/L.介绍了扩容思路和工艺设计参数,评估了实际运行2年后各构筑物的运行性能.采用水解酸化+MBR+Fenton流化床工艺,平均出水CODCr质量浓度低于1...

Design of Upgrading and Extension for the Wastewater Treatment Plant in a Pharmaceutical Industrial Park

A WWTP in Zhejiang Province mostly for pharmaceutical wastewater treatment has reached its full capacity.Available capacity needs to be extended from 10000 m~3/d to 25000 m~3/d.CODCrdischarge limit is also enhanced from≤150 mg/L to≤100 mg/L.Design parameters are introduced and the performance of different treatment units after 2-year operation is evaluated respectively.Averaged effluent concentrations lower than 100 mg/L for CODCr,2.0 mg/L for NH3-N and 0.2 mg/L for TP are achieved using hydrolyze acidification+MBR+Fenton fluidized-bed process.Contaminants are hydrolyzed to more biodegradable forms during the hydrolyze acidification process and then significantly removed by MBR system.Fenton system successively oxidizes those non-biodegradable organic compounds to help ensure that the effluent COD meet the discharge standard.
