Influence of the pH value of influent on the nitrite accumulation was investigated in a biological aerated filter (BAF) operated in normal conditions. The removal efficiency of ammonia nitrogen and the performance of nitrite accumulation in the BAF were also discussed. The results showed that the ammonia nitrogen removal in BAF was heavily influenced by the influent pH value. Drastically fluctuating...
Methyl tert-butyl ether(MTBE) is widely used as gasoline additive. Surface waters in China were polluted by MTBE with different degrees. MTBE was found to be one of the most resistant towards molecular ozone attack and difficult to be degraded by microbe. In this study, experiments were carried out to investigate the removal efficiency of MTBE by catalytic ozonation in the presence of two kinds of...
