HABR反应器处理啤酒废水的实验研究

Experimental Study on Brewer Wastewater Treatment by Hybrid Anaerobic Baffled Reactor

采用复合式折流板厌氧反应器(HABR)处理啤酒废水,并进行了实验研究。试验内容包括厌氧污泥的接种驯化、反应系统的启动运行、在不同影响因素下的运行研究以及和普通折流板厌氧反应器的对比实验等。结果表明:在实验启动开始、启动中期、启动成熟期,ABR反应器内的COD平均去除率分别为40.72%、57.1%、63.64%,HABR反应器内的COD平均去除率为分别43.8%、69.9%、71.78%。HABR反应器处理啤酒废水的最佳水力停留时间为18～24h,温度为25℃,当进水COD为1500mg/L左右时,COD去除率最高达到75%。通过与普通ABR反应器作对比实验,得出带有填料的HABR反应器无论在启动过程还是稳定运行阶段都表现出比ABR更好的效果,具有更高的稳定性。

Hybrid anaerobic baffled reactor（HABR）was used to treat brewer wastewater,with the content of the study including the inoculation and acclimation of anaerobic sludge,startup of HABR,performance of HABR under different factors and contrast experiment with ABR.Results showed that at the early stage,middle stage and mature period of the experiment, average COD removal efficiency of ABR reactor were 40.72%,57.1% and 63.64% respectively,while HABR reactor with removal efficiency of 43.8%,69.9% and 71.78%.Under the best HRT of brewer wastewater treatment 18～24h and temperature 25℃,the influent COD was about 1,500mg/L and COD removal efficiency up to 75%.Through the contrast of ABR and HARB in the experiment,HABR with the fill was better than ABR both in the startup phase and in the operational phase,with more stability.
