摘要
采用 Ｕ Ａ Ｓ Ｂ 反应器—曝气氧化塘组成的系统对玉米淀粉废水处理工艺进行了研究，结果表明， Ｕ Ａ Ｓ Ｂ 反应器按 ８ ｋｇ Ｃ Ｏ Ｄ／ｍ ３ ·ｄ 的容积负荷运行， Ｃ Ｏ Ｄ 去除率达 ９１％ 以上，反应器再次启动时，３ ｄ 即可正常运行，经过 １４２ ｄ 的运行，反应器内生成了污泥指数（ Ｓ Ｖ Ｉ）为 １５～１７ ｍ ｌ／ｇ Ｓ Ｓ的颗粒污泥；厌氧出水再经曝气氧化塘处理后 Ｃ Ｏ Ｄ 小于 １００ ｍ ｇ／ｌ。
A process using UASB reactor followed by an aeration lagoon was demonstrated,to treat wastewater from corn plant.At 35±1℃ and organic loading rate 8 kgCOD/m 3·d,91% of the influent COD was removed by the UASB reactor.Sludge granulation developed quite well and the granular sludge had a sludge volume index(SVI) of 15～17 ml/gSS.It took only three days for the UASB reactor to recover from a long feed break.The COD concentration of the effluent out of the aeration lagoon was less than 100 mg/l.
