【摘要】 在小试基础上，用上流式固体反应器（ＵＳＲ）处理气浮渣维持中温（３３～３５℃）条件，共运行１４０天，试验证明ＵＳＲ适于５８～６３ｇＣＯＤ／（Ｌ·ｄ）的有机负荷，进料ＣＯＤ浓度２００００ｍｇ／Ｌ，ＨＲＴ１２ｈ，出水ＣＯＤ浓度低于６００ｍｇ／Ｌ，ＣＯＤ去除率７２．３％，折算平均产沼气量９．４Ｌ／（Ｌ·ｄ）更多还原

【Abstract】 Abstract A up-flow Reactor was used in this study to treat the scum waste from surface of Dian Pond formed by wastewater discharging of tap-water production factories in Yun Nan province.The 140 days operation showed a COD removal rate of 72.3% with a effluent COD concentration of 600 mg/L and gas production rate of 964L/(L·d) at a inffluent CODconcentration of 20g/L.a HRT of 12h and a Organic loading rate of 58～63gCOD/(L·d)更多还原
