摘　　要：基于反硝化同时脱氮除磷理论,设计了1套连续流一体化脱氮除磷反应试验装置,并实现了反应器的连续稳定运行。在COD为250～350mg·L-1、m(C)/m(N)为5～8的条件下,研究了不同N/P对一体化系统的影响。结果表明,在m(N)/m(P)=5～8的低值时,TP去除率仅有64%,COD、NH3-N、TN的去除率分别可达到90%、98%、90%;m(N)/m(P)在8～10时,COD、NH3-N、TP和TN的去除率分别为91%、98%、90%和90%,达到了GB18918-2002的一级A标准,处理效果最佳;而在m(N)/m(P)=10～14的高值下,除COD的去除率可达到92%外,NH3-N、TP和TN的去除率仅为80%、60%和52%。This study was based upon the theory of simultaneous denitrifying nitrogen and phosphorus removal,laboratory-scale reactor had been designed with integration and continua,and realized continuous operation. The effect with different N/P of the integration system was studied,under the conditions of COD between 250～350 mg·L^-1,m（C）/m（N）=5～8. the results indicated that：the removal rate of COD,ammonia nitrogen and total nitrogen reached 90%,98% and 90%,respectively,but the removal rate of total phosphorus only reached 60%,when m（N）/m（P）=5～8. Likewise,when m（N）/m（P）= 8～10,the removal rate of COD,ammonia nitrogen,total phosphorus and total nitrogen reached 91%,98%,90% and 90%,respectively,and the operation effect was in the optimum efficiency. However,when ratios between 10～14,the experimental effects shown that removal rate of ammonia nitrogen,total phosphorus and total nitrogen reached only 80%,60% and 52%,respectively,except for the removal rate of COD reached 92%.
