Municipal Sewage Treated by a Pilot-Scale Membrane Biological Reactor
摘要
Abstract
It is obviously advantageous for membrane biological reactor to treat municipal sewage over traditional active sludge process. Multi-species microbes in active sludge retained completely by submerged hollow fiber curtain-like micro-filtration membrane module with pore-size of 0.5 mm in an integrated pilot-scale membrane biological reactor self-designed. Meanwhile, the pilot plant comprised an anoxic zone to enable denitrification. In this experiment, two kinds of practical municipal sewage were continuously treated by using this membrane biological reactor in order to evaluate the properties of membrane module, such as the relationship between vacuum degree in membrane module and water flux of membrane, relationship between operational time and water flux of membrane and the way to prevent membrane pollution. Further, all sorts of water quality indexes for inlets and effluents, such as COD, turbidity, NH3-N and apparent colourity were measured in time. And the experimental results showed that there were so excellent water qualities for outlet water as to meet the water-quality standards for urban miscellaneous consumption water. Moreover, the change of sludge concentrations (MLSS) was also monitored on every day. In conclusion, it is instructive for the designing and operational data to commercial applications in the future, which are obtained from this pilot-scale membrane biological reactor.关键词
