Immobilization biological activated carbon used in advanced drinking water treatment
摘要
Abstract
Bacteria separated from a mature filter bed of groundwater treatment plants were incubated in a culture media containing iron and manganese. A consortium of 5 strains of bacteria removing iron and manganese were obtained by repeated enrichment culturing. It was shown from the experiments of effect factors that ironmanganese removal bacteria in the culture media containing both Fe and Mn grew better than in that containing only Fe, however, they were unable to grow in the culture media containing only Mn. When comparing the bacteria biomass in the case ofρ (DO) =2.8 mg/L andρ (DO) =9.0 mg/L, no significant difference was found.The engineering bacteria removing the organic and the bacteria removing iron and manganese were simultaneously inoculated into activated carbon reactor to treat the effluent of distribution network. The experimental results showed that by using IBAC ( Immobilization Biological Activated Carbon) treatment, the removal efficiency of iron, manganese and permanganate index was more than 98% , 96% and 55% , respectively. After the influent with turbidity of 1.5 NTU, color of 25 degree and offensive odor was treated, the turbidity and color of effluence were less than 0.5 NTU and 15 degree, respectively, and it was odorless. It is determined that the cooperation function of engineering bacteria and activated carbon achieved advanced drinking water treatment.关键词
