序批式生物膜法处理含氮废水的影响因素研究
|
|||
|
随着人们生活水平的提高和环境污染的严重，人们对工农业排水的水质的要求也相应提高。本文对处理含氮废水的影响因素进行了研究，以期能够提高SBBR法的处理效率，提高排水水质。结果表明进水COD浓度、C/N、溶解氧、温度在一定范围内的升高有利于含氮物质的去除，但超过一定范围便不利用含氮物质的去除，pH过高或过低均不利于含氮物质的去除。 [ 发自手机版 https://muchong.com/3g ] |

This work studied key factors involved in nitrogen-rich waste water treatment , in an attempt to improve the efficacy of SBBR water-treatment method and the quality of treated water. The results indicated that the raising of the following parameters, such as the COD concentrations in the input, C/N ratio, dissolved oxygen and temperature, within a certain range was beneficial to the removal of nitrogen-containing substances, while it had an opposite effect when exceeded certain limits. Extreme pH, either too high or too low was not suitable for the removal of nitrogen-containing substances. |
