摘　　要：采用两相厌氧-好氧工艺系统治理哈尔滨中药二厂高浓度难降解有机生产废水,通过两相厌氧工艺的运行效果,分析了其在工艺系统中的作用.生产性试验突破了中药废水生物处理技术始终停留在原水COD低于5000mg/L、可生化性良好的易处理废水上的研究现状.现场调试运行结果表明:在进水浓度多为7000~40000mg/L且废水可生化性差(BOD5/COD<0·2)的情况下,产酸相反应器的日平均COD容积负荷可达到20~30kg/(m3·d),平均COD去除率为47·1%;产甲烷相反应器27d启动成功,其COD容积负荷可达到6·0~7·0kg/(m3·d),平均COD去除率为94·06%;两相厌氧工艺系统COD总去除率可达93·0%以上,是整个工艺系统出水达标排放的重要前提.A navel two-phase anaerobic-aerobic treatment technology was developed to treat high concentration and refractory organic wastewater discharge from Harbin Second Traditional Chinese Medicine Factory. The function of two-phase anaerobic process in the whole bio-treatment system was analyzed. Now the status in bio-technique of treating wastewater from traditional Chinese medicine production was that all the influent COD concentration was under 5 000mg/L and its quality was easy to be bio-treated. The full-scale experiment has changed this status. Full-scale experiment results showed that when influent COD concentration was at 7 000～ 40 000mg/L and its BOD_5/COD was lower than 0.2, the volume-loading rate and COD removal rate of acidogenic phase, a continuous-flow stirred tank reactor, could reach 20～30 kg/(m^3·d) and 47.1% respectively. At the same time, it only took the mathanogenic phase 27 days to set-up. The volume-loading rate and COD removal rate of mathanogenic phase, an up-flow anaerobic sludge blanket-anaerobic filter reactor, could reach 6.0～7.0 kg/(m^3·d) and 94.06% respectively. It was also demonstrated the COD removal rate of two-phase anaerobic process was over than 93.0%, which offer endurance for the effluent from the whole treatment system reaching relative standard performed in China.
