| 摘 要： | 研究了膜生物反应器处理垃圾渗滤液的现象及机理,研究表明,反应器内存在较好的短程硝化效果。考察了DO、Ph、C/N等对有机物和氨的去除效果以及对同步硝化反硝化的影响。试验结果表明,在pH值为7.0～8.5,温度为25℃,DO为0.75 mg/L的条件下,短程效果最好,亚硝态氮的积累稳定在90%左右,氨氮去除率可达95%以上,但总氮去除率仅有50%,其原因是碳源不足。

| Abstract: | SND（Short-cut Nitrification and Denitrification）is investigated in a membrane reactor.The results obtained showed that SND are successfully carried out in the reactor.The effects of C/N on DO on removal ratio of COD,NH3-N,TN and SND are discussed.The results showed that the pH value is between 7.0 and 8.0,the temperature is 25 ℃,the best effect of SND can be achieved under 0.75 mg/L of DO,removal ratio of NH3-N can reach over 95% and the removal ratio of TN is only 50%.It has been resulted that the C/N is too low. |
