摘　　要：以MBBR为反应装置,以污泥厌氧发酵液为碳源,重点考察发酵液的投加对MBBR处理生活污水运行性能的影响.结果表明,在发酵液投加量0. 04~0. 6 L的范围内,MBBR系统对污染物的去除能力随投加量的升高而增强.当投加量为0. 6 L时,系统对COD、TN和TP的去除率分别为(85. 7±1. 2)%、(85. 2±1. 1)%和(90. 6±0.6)%.系统可在投加发酵液的条件下保持长期稳定的运行,系统对污染物的去除效果稳定在(85. 9±0. 9)%、(87. 4±1. 8)%和(91. 1±1. 1)%,较空白组分别提高了11.6%、10. 2%和11. 0%.这表明以污泥厌氧发酵液作为污水处理外加碳源具有一定的可行性.With MBBR as the reaction device and sludge anaerobic fermentation liquid as the carbon source,the effect of the fermentation liquid addition on the running performance of MBBR treated domestic sewage was investigated. The results showed that the removal ability of MBBR system to pollutants increased with the increase of dosage in the range of 0. 04 ~0. 6 L. When the dosage was 0. 6 L,the removal rates of COD,TN and TP were( 85. 7 ±1. 2) %,( 85. 2 ± 1. 1) % and( 90. 6 ± 0. 6) %,respectively. The system can maintain long-term stable operation under the condition of adding fermentation broth,and the system’ s removal effect on pollutants was stable at( 85. 9 ± 0. 9) %,( 87. 4 ± 1. 8) % and( 91. 1 ±1. 1) %,respectively. Increased by 11. 6%,10. 2% and 11. 0%. It was indicate that it was feasible to use sludge anaerobic fermentation liquid as a sewage treatment plus carbon source.
