序批式生物膜法處理含氮廢水的影響因素研究
|
|
隨著人們生活水平的提高和環(huán)境污染的嚴重,人們對工農業(yè)排水的水質的要求也相應提高。本文對處理含氮廢水的影響因素進行了研究,以期能夠提高SBBR法的處理效率,提高排水水質。結果表明進水COD濃度、C/N、溶解氧、溫度在一定范圍內的升高有利于含氮物質的去除,但超過一定范圍便不利用含氮物質的去除,pH過高或過低均不利于含氮物質的去除。 [ 發(fā)自手機版 http://www.gaoyang168.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. |
