Study on Factors of Affecting a New SBR Reactor for Nutrient Removal from Municipal Sewage

摘要：

A piece of baffle was introduced into conventional SBR reactor, forming a rotative flow pattern and two reaction areas. In the experiment, the influences of factor as hydraulic retention time (HRT), influent NH3-N concentration, and aeration mode, on the nutrient removal from municipal sewage were investigated. The results show us that when the operating period and aeration time are 6.0 h and 4.0 h, respectively, the system removal efficiency reaches optimal with the removal rate of CODCr NH3-N, TN and TP of 85％, 99％, 81％ and 79％, separately. There are no obvious distances among the treatment effects of decarbonization and nitrification in the united, unlimited, and semi-limite aeration modes. The removal rate of CODCr NH3-N, and TN all reach above 82％, 97％, and 80％, respectively. But only with Semilimited aeration, we can get a satisfying removal rate of TP.
