摘要
在自制生物反应器中,以天津市纪庄子污水处理厂二沉池回流污泥为种泥,通过控制系统的运行条件成功培养出了好氧颗粒污泥,并研究了其除污性能。试验结果表明:该好氧颗粒污泥具有良好的沉降性及生物活性,并具有良好的除污效果和硝化脱氮能力,对COD、NH4+-N的去除率可达到90%、80%以上,达到国标GB 18918-2002一级排放标准。
Granular activated sludge was cultivated in a sequencing batch reactor using floccular activated sludge of Jizhuangzi municipal wastewater treatment plant in Tianjin as seeding sludge by controlling operational conditions. The results show that aero- bic granular sludge has good settleability and high biomass retention. It can achieve high COD removal rate and has high nitrifica- tion. The removal rates of COD and NH4＋ - N come up to 90% and 80% respectively, reaching the national emission standard of GB18918-2002 level 1.
