摘　　要：以深圳某水质净化厂为研究对象,考察AOA耦合MBBR工艺对实际生活污水的处理效果,验证投加MBBR填料对AOA工艺的促进作用。结果表明,AOA耦合MBBR工艺取得了较好的处理效果,在不投加外碳源的条件下COD、NH_(4)^(+)-N、TN、TP平均出水浓度分别为17.65、0.28、3.58、0.21 mg/L,平均去除率分别为93.15%、98.89%、91.07%、93.24%。耦合工艺在冬季较冷的不利时段有一定的正向作用,且对好氧段的促进作用明显。好氧段MBBR填料富集的专性微生物可强化AOA工艺的硝化作用,提升氨氮和总氮去除率。这为高密度城区水质净化厂的原位扩容改造提供了新的技术思路。The anaerobic-aerobic-anoxic(AOA)process was coupled with the moving bed biofilm reactor(MBBR)process,and was used to treat actual domestic wastewater in a treatment plant in Shenzhen.The objective is to verify the enhancement effect of adding MBBR media on the AOA process.The results indicated that the AOA-MBBR coupled process achieved significant treatment efficiency,with average effluent concentrations of COD,NH_(4)^(+)-N,TN,and TP at 17.65 mg/L,0.28 mg/L,3.58 mg/L,and 0.21 mg/L,respectively,without the addition of an external carbon source.The average removal rates for these parameters were 93.15%,98.89%,91.07%,and 93.24%.Notably,the coupled process showed enhanced performance during winter,particularly in the aerobic zone,where biofilm-attached microorganisms improved the nitrification capacity of the AOA process,leading to higher ammonia and total nitrogen removal rates.These findings offer a promising technical approach for the in-situ expansion and upgrading of wastewater treatment plants in densely populated urban areas.
