A_1-A_2/O法处理高浓度氨氮废水最佳条件确定

The Optimum Conditions Determination of A_1-A_2/O Method Treatment to High-concentrated Ammonia-nitrogen Wasted Water

试验用水主要污染因子:化学需氧量(COD)、氨氮(NH3-N).采用国家标准分析方法进行分析.对影响处理效率的环境因素及工艺参数进行研究确定.工艺参数的试验过程包括:最佳水力停留时间的确定;混合液回流比的确定;系统进水C/N比对硝化效果的影响等.

The main pollution factors chemical oxygen consumption （COD）and ammoniacal nitrogen（ NH3 -N） of the experiment water are analyzed according to the National Standard Analysis Method after studying the treatment effectiveness influenced by the environment factors and the technology reference data. The tests to determine the technology reference data include： determination to the retention period of the optimum water force;determination to the return current radio of the mixed liquid and the influence to the nitrating effective-ness of C/N （ Carbon - Nitrogen） ratio in the system supplying water.
