提高常规净水工艺除氮能力的试验

介绍了一种微污染源水中去除氨氮的小型动态试验的结果，以凹凸棒粘土为启动期的生物载体替代生物陶粘或软性填料，采用脱氮反应池串联或并联于常规净水工艺两种工艺流程，取得了类似其他生物氧化法的除氮效果，并且具有无明显生物培养期及启动快的特点，考了影响因素和含氮化合物在净化过程中的举动。

Experimental Research on Augmentation of Nitrogen Removal in Conventional Water Treatment Process

The result of dynamic experiment for ammonia nitrogen removal from micro polluted raw water is studied in this paper. Attapilgite is used as biofilm carrier substitution for bioceramics or wadding, and reaction pool in series or parallel connection for nitrogen removal is joined into the conventional process flow for purifying water. The effect of nitrogen removal by this method is the same as that by biological oxidation method with such advantages as no obvious biological cultivation phase and speedy startup. Affecting factors and behavior of nitride in water purification are also studied.
