摘要
文章研究了城市污泥中掺杂粉煤灰在不同实验条件下(不同配比、不同pH和反应时间)生活污水中BOD5、CODCr和SS的去除效果,试验结果表明:当城市污泥与粉煤灰按6:3的比例混合,pH为7,反应时间为15～20min时,生活污水中BOD5的降解率为50%,CODCr的去除率为60%,SS的去除率为54%,为减轻生活污水水的后续处理负荷、降低后续处理成本和探索废物资源化等提供试验依据。
The removal rate of biological oxygen demand, chemical oxygen demand and suspended solids in sewage was researched by municipal sludge doping with fly ash in different experiment conditions that was different ratio, temperature and pH value. The results showed that when the ratio of waste activated sludge and fly ash was 6：3, pH was 7, reaction time was 15-20 min, the BOD5, CODEr, and SS removal rate were, 50%, 60% and 54% respectively, which could supply experimental basement in alleviating the next treatment burden, lowing the next treatment cost and exploring the resource reuse of solid wastes.
