A highly efficient, economic, and environmentally friendly hybrid membrane bioreactor-reverse osmosis (MBR-RO) was simulated for the treatment of meat-processing wastewater. The effluent elucidated ≥92% reduction in the COD, TKN, NO3––N, TN, TSS, and TP parameters. The aerobic MBR accounted for over 62% of the total operation cost that predominantly dealt with the electricity demand (94.19%), while climate change (95.13%) and photochemical oxidation formation (4.66%) categories imposed the highest environmental burdens. Fossil fuel utilization as the major energy supplier (97.26%) significantly enhanced the CO2 emission that led to augmented environmental impacts. Most sensitivity to change of prime parameters was reflected by the agricultural land occupation (19.25%) and ozone layer depletion (18.97%) categories. Accordingly, the proposed hybrid MBR-RO can be nominated as a promising system to overcome problems emerged from the meat-processing wastewater.

好氧混合膜生物反应器-反渗透模拟系统高效回收肉类加工废水：全面的经济和环境研究
模拟了高效，经济，环保的混合膜生物反应器-反渗透（MBR-RO）处理肉类加工废水。废水表明COD，TKN，NO 3 – –N，TN，TSS和TP参数减少了≥92％。有氧MBR占总运营成本的62％以上，主要用于解决电力需求（94.19％），而气候变化（95.13％）和光化学氧化形成（4.66％）类别则对环境造成了最大的负担。化石燃料作为主要能源供应商（97.26％）显着提高了CO 2的利用率导致增加环境影响的排放。对主要参数的变化最敏感的是农业用地（19.25％）和臭氧层消耗（18.97％）类别。因此，拟议的混合型MBR-RO可以被提名为解决肉类加工废水中出现的问题的有前途的系统。
