摘要
为了更好地推进连续流好氧颗粒污泥工程化应用,在河北省某生活污水处理厂进行中试试验,平均处理水量为1 743 m3/d,水力停留时间为10.80 h。结果表明:经过2个多月的运行,成功培养出好氧颗粒污泥,形成的颗粒结构密实,呈黄褐色,表面光滑,污泥有较好的沉降性能;好氧颗粒污泥在形成过程中可以产生大量的蛋白质(PN)和多糖(PS),PN/PS由3.59增长到6.88,PN/PS呈上升趋势,PN对污泥颗粒化过程起到重要作用;同时,好氧颗粒污泥系统对污染物有良好的去除效果,CODCr、TN、氨氮的平均去除率分别为89.70%、86.0%和98.42%,有良好的抗冲击能力和脱氮效率。
In order to promote the engineering application of continuous flow aerobic granular sludge(AGS),a pilot test on AGS was carried out in a WWTP in Hebei Province,the average water treatment volume was 1743 m^(3)/d,and the hydraulic retention time(HRT)was 10.80 h.The results showed that:after 2 months of operation,the aerobic sludge(AS)could successfully form the AGS with dense structure,yellow brown,smooth surface and good settling performance.AGS could produce more protein(PN)and polysaccharides(PS)during its granulation process,PN/PS increased from 3.59 to 6.88,PN played an important role in sludge granulation process.At the same time,the average removal rates of CODCr,TN and ammonia nitrogen of the AGS system were 89.70%,86.0% and 98.42%,respectively,which reflected good impact resistance and nitrogen removal efficiency.
