摘要
曝气技术是黑臭水体整治的一项有效措施。综述了曝气技术在国内外黑臭水体治理上的应用,研究了黑臭水体需氧量计算的三种方法,利用组合推流反应器模型思想,结合生物膜降解污染物机理,设计建立了一种适用于黑臭河道湖泊需氧量计算模型-改进型组合推流反应器。利用该模型计算商丘某河道需氧量,结果表明整治期间总需氧量为6 305 kgO2,黑臭水体整治前20天需氧量大,占总需氧量的83.1%,因此在黑臭河道治理前期需及时补充溶解氧,为微生物降解污染物提供溶解氧条件。
Aeration is suitable for the treatment of polluted water.In this paper,The application of aeration technology in the treatment of polluted water is reviewed.Three calculation methods of oxygen demand is researched,and a improved combined push flow reactor is designed and established which combined with the mechanism of biological membraneand combined push flow model.The case of oxygen demand is calculated,accounting for 83.1%of the total oxygen demand in the first twenty days,so provide sufficient dissolved oxygen for microbial degradation of pollutants.
