用接种成熟的高盐好氧颗粒污泥的序批式反应器(SBR)处理高盐榨菜废水,考察了有机负荷及DO对好氧颗粒污泥去除主要污染物特性的影响.结果表明:有机负荷过高或过低均会影响颗粒粒径及结构,从而影响反应器对污染物的去除.提高DO有助于去除COD,但其过高或过低都会导致亚硝酸盐的积累和颗粒污泥微环境的分布,从而影响到对其他污染物的去除效果,以DO为7.0 mg/L时反应器的除污效能最佳.
用接種成熟的高鹽好氧顆粒汙泥的序批式反應器(SBR)處理高鹽榨菜廢水,攷察瞭有機負荷及DO對好氧顆粒汙泥去除主要汙染物特性的影響.結果錶明:有機負荷過高或過低均會影響顆粒粒徑及結構,從而影響反應器對汙染物的去除.提高DO有助于去除COD,但其過高或過低都會導緻亞硝痠鹽的積纍和顆粒汙泥微環境的分佈,從而影響到對其他汙染物的去除效果,以DO為7.0 mg/L時反應器的除汙效能最佳.

The wastewater containing hypersaline preser ved szechuan pickle has been treated by sequencing batch reactor(SBR) with well-inoculated hypersaline aerobic granular sludge(AGS).The influences of organic loading and dissolved oxygen(DO) on major characteristics of pollutant removal with AGS are studied.Results show that either too high or too low organic loading can influence the particle size and structure of granular sludge,in order to affect the removing effect on pollutants.The increase of DO is good for COD removal,but either too high or too low can result in nitrite accumulation and the distribution of granular sludge in micro-environment,which will affect other removing effects on pollutants.The removing efficiency of the reactor reaches the best,when DO is controlled at 7.0 mg/L.
