摘要
Abstract
Integrated unit of ozone and biological aerated filter (BAF)was used to treat organic polluted wastewater containing ammonia nitrogen. The results indicate that removal rate of ammonia nitrogen decreases with the increase of ammonia nitrogen concentration in influent,the ideal ammonia nitrogen loading is 0. 17 ~ 0. 25 kg / m3 ·d,and then removal rate of ammonia nitrogen can be above 60% stably. Ammonia nitrogen in influent has some negative influence on COD removal. When concentration of ammonia nitrogen is more than 60 mg / L,effect of COD removal turns worse obviously. Lipid-phosphorous method was applied in biomass measurement of the integrated ozone-BAF unit to treat biomass distribution in the system. It is shown that in the area near inlet,when sampling height isn’t more than 1. 2 m,biomass is extremely rare as a result of the high ozone disinfection. Biomass reaches maximum when the vertical distance is 1. 5 m,and then biomass declines with the increase of sampling height.关键词
