| 摘 要： | 针对淹没生物膜法(SBF)和污泥臭氧化各自在污泥减量方面的优点,提出了化学臭氧化和复合生物膜法相结合的污泥减量工艺,并对臭氧化对SBF运行效能的影响进行了实验研究。通过2个并行的SBF系统污泥臭氧化结果进行对比,结果显示臭氧化能够显著降低系统的污泥产率(0.043 kg/kg,较不加臭氧化的SBF系统下降了76%),同时不对硝化和有机物的去除作用产生明显的影响,系统出水水质良好。 |

| Abstract: | A experimental study of sludge reduction in combination of the chemical ozone oxidation and biological method was made,with integrating the merits of SBF and sludge ozonation.The characteristics of sludge the ozonation and its influence on SBF performance were investigated.Two parallel SBF systems were run in order to compare ozone oxidation system and no ozone oxidation system.The results showed that ozonation was able to reduce markedly the sludge production rate of the system,with a sludge production rate of 0.043 kg/kg which was reduced by 76%,and no obvious influence was observed on nitration and organic removal,the outflow water quality of the system was also good. |
| Keywords: | ozonation sludge reduction submerged biofilter |
