摘要
采用人工配制的低C/N废水对常规A2/O系统和强化ANAMMOX系统进行冲击试验,确定其冲击耐受极限,并比较采用ANAMMOX技术的优劣。结果表明,低C/N废水对A2/O系统的脱氮功能有明显的抑制作用,C/N=3.5可有效降低系统的硝化功能,C/N=1.2可使反硝化功能完全停止;而采用ANAMMOX反应的A2/O系统对低C/N废水冲击下的脱氮能力有一定的提高,同比条件下,NH4+-N去除率提高约9%,TN去除率提高约5%;但ANAMMOX反应对系统反硝化功能、COD和TP去除功能的作用不明显,同比条件下,两套系统的去除率差异不显著。
The shocking experiment as to ANAMMOX system and normal system was conducted by using artificial preparation of the low C/N ratio of wastewater. The shocking tolerance limit was determinined, and the merits of ANAMMOX technology was compared. The results showed that, low C/N wastewater has obvious inhibition to the A^2/O system for nitrogen removal. The C/N ratio of 3.5 could reduce the ftmction of nitrification effectively and C/N ratio of 1.2 could stop the function of denitrification completely. However, the nitrogen removal of the A^2/O system which use ANAMMOX get some improvement in treating low C/N wastewater under the same conditions. The average NH4^＋ -N removal was increased to 9% and TN removal was increased to about 5%, while ANAMMOX is ineffective in denitrification and the removal of COD and TP. Under the same conditions, the removal of the two systems has no notable differences.
