摘　　要：为处理高浓度难降解中药废水,采用交叉流好氧反应池(CAR)作为生物处理的最后方法进行了生产规模试验研究.从CAR反应池的运行情况和微生物相观察来看,虽容积然经过两相厌氧工艺处理后进入到CAR的废水仍属不易生物降解废水,而且浓度高(3-4g/L以上),COD容积负荷大(5-6kg/m3.d),CAR仍可以发挥传统好氧反应池难以达到的效力:填料迅速挂膜、微生物生长良好、去除率99%以上、出水稳定且达到松花江水系排放标准.运行结果证明了,CAR反应池的独特专利结构,使它具有高效性和抗冲击负荷能力,更适宜处理经过一定可生化性调节的高浓度难降解工业废水.A full -scale experiment used Cross -flow Aerobic Reactor （CAR） as the last bio -treatment method was done in order to treat highly concentrated and refractory wastewater from traditional Chinese medicine production. The results of CAR＇ s running and the observing of the microorganism of CAR showed that CAR could perform a good function unlike any other traditional aerobic reactors under the difficult status： the influent BOD5/COD was very low after the treatment of two - phase anaerobic, the influent COD concentration was at 3 - 4g/L, and its COD volume -loading rate reach 5 ~ 6kg/m^3·d. At the same time, the organisms on the padding of CAR grew fast and good; the removal efficiency of effluent COD was above 99% ; the stable character of effluent was able to meet the requirement of discharge standard of Song Hua river. This full -scale treatment showed that CAR＇ s special patent structure made it had high efficiency and ability against impulsion, and it was adapt to treat high concentration and refractory organic wastewater after anaerobic biodegraded.
