摘　　要：中试用内循环厌氧反应器处理制浆造纸厂的洗草废水,并探讨内循环系统的循环状况。试验表明,洗草水不适合进行深度厌氧处理,宜进行水解酸化。由于洗草废水的有机物浓度低,产气量小,反应器内循环系统仅产生了不连续的提升,液体提升量与产气量的比值在0.08~0.36,下降管中产生了间歇性回流,液体的流量达到了518.4~725.1 L/h。The IC reactor is used to treat the straw-washing water produced in a pulping and papermaking mill in experi-ment .The result shows that hydrolysis-acidification process is more appropriate than anaerobic process when treating the straw-washing water .Due to low concentration of the organism in the wastewater and less gas production ,the inner circula-tory system of the reactor only produces discontinuous ascending flow .When the ratio of flow rate and gas production rate is 0 .08-0 .36 ,the downward pipe produces intermittent backflow and backflow rate can reach 518 .4-725 .1 L/h .
