| 摘 要： | 本文通过对两套生产没备,在不同反应时间情况下"黑砂"的形成及除锰能力的观测、分析,以及曝气含铁、锰地下水自然氧化的静态与动态模型试验,发现反应时间对"黑砂"的形成及除锰能力的堤高有显著影响,得出充分的反应时间是"黑砂"除锰的必要条件.

| Abstract: | The formation process of "black-sand" and its manganese removal abilities with regard to different reaction time have been observed and analyzed in two sets of water treatment equipmenty.A static and an dynamic natural oxidation reaction and model tests of aerated iron and manganese-bearing ground water have also been carried out. It is found that the reaction time has a singnificant influence on the formation of "black-sand" and the development of its manganese removal ability.Hence, it is necessary to give sufficient reaction time in the aeration-contact oxidation process for manganese removal. |
