摘要
分别以乙酸钠、葡萄糖和白砂糖作为外加碳源,考察了其对生物处理系统反硝化脱氮效果的强化作用。结果表明,在一定条件下,三种物质对系统的反硝化能力均具有明显的强化效果,但其有效作用时间和反硝化速率有所不同,以乙酸钠为碳源时的反硝化速率约为以葡萄糖和白砂糖为碳源时的2倍,而在同等COD投加当量下的有效作用时间约为葡萄糖和白砂糖的一半。
The effect of biological nitrogen removal enhanced by external carbon source, such as sodium acetate, glucose and white granulated sugar was investigated. The resuhs indicate that all the three kinds of carbon sources have obvious enhancing effect on the biological nitrogen removal capacity, but with different reaction time and reaction velocity in given conditions. The denitrification rate with so- dium acetate as carbon source is about twice that with glucose and white granulated sugar, with only half of reaction time with equivalent COD dosage.
