摘要
通过低温下的硝化速率试验并结合芦村污水处理厂升级改造实例,对新型SPR1悬浮填料的生产性强化硝化效果进行了分析。结果表明:在37%的填料填充率下,与不投加悬浮填料相比,系统硝化速率和硝化效果分别提高123%和99%,悬浮填料的投加强化了系统硝化;在填充率37%的悬浮填料—活性污泥复合系统中,悬浮填料表面上的附着硝化菌和混合液悬浮硝化菌对系统硝化速率的贡献分别为68.5%和31.5%;悬浮填料的工程应用效果良好,在47%的填料填充率下,低温季节系统的生产性硝化效果得到强化,平均提高60%。
This paper carried out the nitrification rate experiment under low temperature to study a new type of SPR-1 suspended filler enhanced nitrification effects,and analyzed the productive enhanced nitrification effects of suspended filler by taking the Lucun Wastewater Treatment Plant upgrading reconstruction project as case study.The results showed：with the filling rate of 37%,compared with the no-suspended-filler system,the system nitrification rate and effects of this measure increased by 123% and 99% respectively,which meant the suspended filler improved the systematic nitrification effects;in the combined system of suspended filler-activated sludge with 37% filling rate,the contribution from the nitrobacteria adhered to the filler surface and suspended in the mixture liquid to nitrification rate was 68.5% and 31.5% respectively;the engineering application effects of suspended filler was satisfying,with the 47% filling rate,the productive nitrification effects under low temperature was improved by 60% on average.
