摘要
试验研究了4格室厌氧折流板反应器（ABR）处理浓度为50~300mg/L的难降解黄连素废水,包括启动实验和后续操作运行,共计175d,其中启动运行80d,反应温度控制在（32±1）℃.结果表明,采用低黄连素负荷的方法驯化污泥,其启动过程比较快,ABR反应器污泥经过80d的驯化培养后,微生物对黄连素具有一定的适应性;启动后逐渐提高进水黄连素浓度,最高达到300mg/L,当进水黄连素浓度为120mg/L时,ABR反应器的处理效果最好,COD和黄连素的去除率分别达到70%和95%左右,此时各格室污泥平均浓度分别达到24.06,24.76,27.76,6.4g/L,污泥外观呈红褐色和黑色.
A four-compartment anaerobic baffled reactor（ABR） fed on berberine wastewater was run under a berberine concentration between 50 and 300mg/L.The start-up and operational performance（total 175 days,including the start-up of 80 days） of the ABR was studied at（32±1）℃.Inoculums taken from Northeast Pharmaceutical Wastewater Treatment Plant were acclimated.Microorganism possessed definite adaptability on berberine wastewater after 80 days＇ cultivation of ABR sludge.Under the berberine concentration 120mg/L the performance of ABR was the best,while the concentrations of berberine and COD in every compartment tended to decrease gradually;the removal rates of berberine and COD reached about 95 and 70 percent,respectively.The study on characteristics of sludge showed that sludge in each compartment was reddish-brown and black which the average MLSS of each compartment was 24.06g/L,24.76g/L,27.76g/L,6.4g/L,respectively.
