| 摘 要： | 利用序批式移动床生物膜反应器研究了有机碳源对低碳氮比ρC/ρN(指ρCOD/ρTN,以下同)生活污水同步硝化反硝化脱氮的影响,结果表明,在无外加碳源时,同步硝化反硝化条件下TN去除率为59.8%,COD平均去除率为83.12%,NH+4-N去除率为94.9%(最高达到99.8%);分别以淀粉、葡萄糖和甲醇为外加碳源,ρC/ρN=7时,发现投加外碳源有利于有机物、NH+4-N和TN的降解和转化,NH+4-N转化受碳源种类影响不大,投加淀粉时有机物降解不完全导致系统有恶化趋势,投加甲醇碳源时系统脱氮效率最高,TN去除率达84.5%,投加葡萄糖时,TN去除率为80.55%,从安全和经济方面考虑,确定投加葡萄糖较为合适.

| Abstract: | The present paper aims to introduce research of the effect of organic carbon on the denitrogenation using simultaneous nitrification and denitrification in moving-bed biofilm reactor.COD/TN ratio was about 3 in real domestic wastewater. The result of the treatment show that at the end of aeration the average removing rate of TN,NH+4-N and COD can reach 59.8%,83.12% and 94.9%,respectively.In order to improve the efficiency of removing TN,the experiment added amylum,glucose and methanol.The results show that ... |
