摘要:- ZeeLungTM膜傳氧生物膜反應(yīng)器工藝（ZeeLungTM MABR工藝）在美國伊利諾斯州YBSD污水處理廠成功應(yīng)用，成為目前世界上最大的MABR污水處理廠。ZeeLungTM MABR工藝將原有的好氧活性污泥系統(tǒng)改造成A2O工藝系統(tǒng)，ZeeLungTM膜箱安裝于改造后的缺氧池，在不新建生化構(gòu)筑物的條件下，即可滿足日益增長的有機(jī)負(fù)荷及新的出水總磷指標(biāo)要求(低于1 mg/L,通過生物除磷即可實(shí)現(xiàn))。為期1年的運(yùn)行數(shù)據(jù)表明，升級后系統(tǒng)的出水水質(zhì)可穩(wěn)定達(dá)到目標(biāo)要求，實(shí)現(xiàn)了生物除磷及ZeeLungTM池內(nèi)的同步硝化反硝化。ZeeLungTM生物膜優(yōu)先進(jìn)行硝化，平均傳氧速率為12.0 g/(m2·d)，在平均硝化速率為2.1 g/(m2·d)的條件下，80%的傳氧用于硝化，在保持傳氧能力的前提下確保氨氮及總氮的同步去除效果。半經(jīng)驗(yàn)動(dòng)力學(xué)模型可用于模擬ZeeLungTM的硝化速率，其溫度系數(shù)接近于1，表明水溫對ZeeLungTM硝化速率的影響很小。
Abstract:- ZeeLungTM membrane aerated biofilm reactor (MABR) technology has been successfully applied in wastewater treatment plant (WWTP) of Yorkville-Bristol Sanitary District (YBSD) in Illinois, USA, and it has become the largest MABR WWTP in the world currently. The original aerobic activated sludge system was transformed into the A2O process system by ZeeLungTM MABR process. ZeeLungTM cassettes were installed in the retrofitted anoxic tanks to meet the increasing organic loading and new effluent total phosphorus (TP) limit(less than 1 mg/L, by biological phosphorus removal)without building new biological tanks. One-year operational data demonstrated that the effluent quality of the upgraded system could achieve the target stably, and the biological phosphorus removal and simultaneous nitrification and denitrification in ZeeLungTM tank were realized. ZeeLungTM biofilm prioritized nitrification. The average oxygen transfer rate (OTR) of ZeeLungTM was 12.0 g/(m2·d). When the average nitrification rate (NR) was 2.1 g/(m2·d), more than 80% of OTR were utilized for nitrification, indicating that stable nitrification and simultaneous total nitrogen (TN) removal were achieved under the premise of maintaining the oxygen supply capability. The semi-empirical kinetic model well predicted the NR of ZeeLungTM, and the temperature coefficient was close to 1, indicating that water temperature had little influence on NR of the ZeeLungTM.
