摘要
为了探讨MBBR中载体填充率对水体修复效果的影响,以城市黑臭水体为研究对象,考察载体填充率与有机物、氨氮、浊度、透明度修复效果响应关系,并建立MBBR系统底物降解动力学模型。结果表明:系统最佳填充率为15%,此时反应器对COD、NH_(3)-N、浊度的最大去除率分别为78.51%、87.80%、96.54%,透明度从4.10 cm提高到33.00 cm,能保持载体流化状态下实现高效稳定的污染物去除效果,并得出在最佳填充率15%时的有机物、氨氮降解动力学常数。
In order to discuss the effect of carrier packing ratio on water restoration efficiency,taking urban black and odorous water body as the research object,the relationship between carrier packing ratio and restoration efficiency of organic matters,ammonia nitrogen,turbidity and transparency was investigated,and a substrate degradation kinetic model was established in MBBR system.The results showed that,the optimal packing ratio of the system was 15%,at this time,the maximum removal rates of COD,NH_(3)-N and turbidity were 78.51%,87.80%,96.54%respectively,the transparency of the reactor was increased from 4.10 cm to 33.00 cm,which could achieve efficient and stable pollutants removal effect under carrier fluidization state.The kinetic constants of organic matters and ammonia nitrogen degradation at the optimal packing ratio of 15%were obtained.
