  • Abstract: 自生动态膜生物反应器是一种具有很大潜力的污水处理技术。为了检验自生动态膜生物反应器的处理效果,设计建造了一套平行排列自生动态膜生物反应器,以棉布作为动态膜基质,对低浓度污水的处理效果进了研究。结果表明:平行排列自生动态膜生物反应器不容易发生堵塞;棉布作为动态膜基材容易解体,不适于作为膜基质;COD、NH3-N、TN、TP 的平均去除分别为16.47%、28.17%、15.44%、27.51%,装置对低浓度污水有一定的去除效果,对常规水质的污水处理效果还需要试验证明。
  • Self-forming dynamic membrane bioreactor is a potential wastewater treatment technology. In order to test the treatment effect of self-forming dynamic membrane bioreactor, a set of parallel arrangement self-forming dynamic membrane bioreactor was designed and constructed. Cotton cloth was used as the dynamic membrane substrate to study the treatment effect of low-concentration sewage. The results show that the parallel arrangement of self-forming dynamic membrane bioreactors is not easy to clog. As a dynamic film substrate, cotton cloth is easy to disintegrate and is not suitable as a film substrate. The average removal rates of COD, NH3-N, TN and TP were 16.47%, 28.17%, 15.44% and 27.51% respectively. The removal efficiency of low concentration sewage is low, and the results of domestic sewage treatment for conventional water quality still need to be proved by experiments.
