MBBR处理生活、生产混合污水
Moving Bed Biofilm Reactor for Treatment of Mixed Domestic and Industrial Wastewater
【摘要】 采用移动床生物膜反应器(MBBR)处理生活、生产混合污水,研究了对有机物的去除效果,并考察了容积负荷、填料填充比例、水力停留时间等参数对MBBR处理效果的影响。试验发现,在填料填充比例为60%(体积比),单级反应器的水力停留时间为6h、容积负荷为4.0~5.0kgCOD/(m3·d)的条件下,反应器运行稳定且处理效果好,最终出水COD平均为60mg/L,去除率>90%。
【Abstract】 Moving bed biofilm reactor (MBBR) was used for treatment of mixed domestic and industrial wastewater, in order to study the removal efficiency of organic matters and investigate the influence of volumetric loading, carrier volumetric ratio, and hydraulic retention time (HRT) on the treatment effect. It is observed that under the conditions that carrier volumetric ratio is 60%, HRT in single reactor is 6 h, and volumetric loading is 4.0-5.0 kgCOD/(m~3·d), MBBR operates steadily with good effect, and the effluent COD is 60 mg/L in average, with removal rate more than 90%.
