吹脱法去除采气废水中氨氮的影响因素研究
|
摘要
研究以四川地区采气废水经低温蒸馏处理后的水样作为研究对象,其氨氮的质量浓度为51.6mg/L,通过正交试验和单因素试验较为系统的探讨了曝气量、温度、pH值等相关因素对吹脱法去除采气废水中氨氮的影响。此外,在大量的试验数据中选取了较为适宜的处理条件,进行了一系列验证实验,试验结果表明在曝气量为2L/min、pH值为11、温度为80℃条件下,氨氮去除率可达90%以上,吹脱法处理采气废水中氨氮能够满足达标排放要求。
In this paper, water samples of gas production wastewater treated by low-temperature distillation in Sichuan are taken as the object of study. The mass concentration of ammonia nitrogen is 51.6 mg/L. Through orthogonal test and single-factor test, systematically discussed influencing factors such as aeration rate, temperature and pH value on ammonia nitrogen removal from gas production wastewater by air stripping. In addition, a series of verification experiments were carried out by selecting suitable processing conditions from a large number of experimental data. The results show that the removal rate of ammonia nitrogen can reach 90% when aeration rate is 2 L/min, pH value is 11 and temperature is 80℃,and ammonia nitrogen removal from gas production wastewater by air stripping method can meet the standard discharge requirements
