| 摘 要： | 研究曝气方式对养鱼水体中生物脱氮的影响规律,实验结果表明,采用曝气的方法,可以有效降低废水中有害的氨氮和亚硝酸盐的浓度,但水体中总氮降低的幅度很小;间歇曝气不利于水体氨氮的快速降低,但是可以有效控制水体中亚硝酸盐和硝酸盐的浓度,其对水体中总氮的去除效率较高,可以达到52%。

The effect of aeration patterns on biological nitrogen removal in fish-farming wastewater |
| |
| Abstract: | The law of the effect of aeration patterns on biological nitrogen removal in fish-farming wastewater was investigated in the paper.The main results are as follows：total nitrogen in fish-farming wastewater was little removed while ammonia and nitrites were removed effectively under continuous aeration.On the other hand,under intermittent aeration,the degradation rate of ammonia was still too slow but the concentrations of nitrites and nitrates were controlled perfectly.In addition,the removal rate of total nitrogen was 52% under intermittent aeration. |
