摘　　要：测定了新技术白腐菌-APMP制浆各工段废水发生量和污染负荷，并用厌氧-好氧生物技术处理白腐菌-APMP制浆废水。结果表明：白腐菌-APMP制浆废水发生量在30m^3／t浆左右，CODCr发生量为100～130kg／t浆，BOD，发生量为30-40kg／t浆。厌氧-好氧组合技术可使白腐菌-APMP制浆废水CODct从3578mg／L降至246mg／L、BOD5从1231mg／L降至20mg／L、SS从482mg／L降至57mg／L，生物处理的结果达到了国标GB3544-2001排放标准。UASB厌氧技术适宜处理高浓有机废水和低的运行能耗，近年来厌氧处理制浆造纸废水技术正在走向工业化；序列活性污泥法技术则能预防污泥膨胀，本研究实现了高效低能耗处理白腐菌-APMP制浆废水的目标，并具有良好的工业应用前景。Effluents from white-rot fungi treated chips APMP pulping were collected, the amount of effluent generation was measured and its pollution loads were investigated. A combined anaerobic-aerobic treatment process was used for the effluent treatment. The generation of effluent is of about 30m^3 per metric ton of oven-dried pulp, the load of CODCr about 100 - 130 kg/mt o.d. pulp and that of BOD5 about 30 - 40 kg/mt o.d. pulp. UASB reactor was used for anaerobic stage, and SBR reactor used for aerobic treatment, the floccullation used as the last stage. The pollution removal efficiencies of anaerobic-aerobic treatment indicate that this type effluent could be easily treated. The CODCr, BOD5 and SS loads of inlet effluent were 3578 mg/L, 1231mg/L and 482mg/L respectively, those of outlet effluent were significantly reduced, with CODCr of 246 mg/L, BOD5 of 20mg/L and SS of 57mg/L in discharged water, which can meet the requirement by the national effluent discharging regulation, BG3544 -2001.
