摘要
结合两种温度条件下的对比实验结果,从生物去除效果、膜去除效果、系统去除效果三个方面系统地分析了温度对一体式膜生物反应器(IMBR)污水处理效果的影响.实验结果表明,低温条件下(14～19℃)COD的生物去除效果较中温(26℃±1℃)条件差,但低温条件下较好的膜去除效果足以补偿生物去除效果的不足,使得低温条件下的系统去除效果略优于中温条件.在硝化菌的适应期内,中温条件下NH3 N的生物去除效果与系统去除效果均优于低温条件.适应期后无太大差别,温度对NH3 N的膜去除效果影响很小.
The effect of temperature on the wastewater treatment with IMBR was analyzed from three aspects according to the result of the experiment: the removal contributed by microorganism,the total removal,and the removal contributed by membrane.The results of the experiment show that the COD removal contributed by microorganism is lower than that in medium temperature,but the COD removal contributed by membrane in low temperature is high enough to offset that shortage,and the total COD removal in low temperature is slightly higher than that in medium temperature.During the adapting time of nitration bacteria,the NH_3-N removal contributed by microorganism and the total NH_3-N removal in low temperature are lower than that in medium temperature,and the distinction is small after the adapting time.The impact of temperature on NH_3-N removal contributed by membrane is not significant.
