中文摘要:
      为研究降流式厌氧污泥床(DASB)对脱墨废水降解特性的影响,采用DASB反应器对某造纸厂的脱墨废水进行厌氧处理。考察了脱墨废水的化学需氧量(COD)质量浓度、COD去除率、pH值和混合液悬浮固体(MLSS)值的变化,以及厌氧污泥的特性。结果表明,DASB反应器在处理脱墨废水的启动阶段,对COD的去除率稳定在62%左右,启动效果较好;在负荷运行阶段,COD的平均去除率较高;在进水中投放NaHCO3可调整反应器的酸化现象,并且在运行过程中各个格室的MLSS有缓慢增加的趋势,最终处于稳定状态。通过此试验,明晰了DASB反应器在环境温度条件下的启动过程,从而更好地进行反应器的运行控制,实现运行过程优化,并且为DASB反应器处理有机废水提供了重要依据。
英文摘要:
      In order to study the degradation characteristics of the deinking wastewater by the down flow anaerobic sludge bed (DASB) reactor, the deinking wastewater which was from a paper mill was subjected to anaerobic treatment using a downflow anaerobic sludge blanket reactor. During the period, the changes of chemical oxygen demand (COD) mass concentration, COD removal rate, pH value, mixed liquid suspended solids (MLSS) value and the characteristics of anaerobic sludge were investigated to reveal the degradation characteristics of the reactor. The results showed that the removal rate of COD in the DASB reactor during the start-up phase was stable at about 62%, and the start-up effect was better. The average removal rate of COD was higher in the load operation stage. When NaHCO3 was introduced in the influent water, the acidification phenomenon of the reactor can be adjusted. During the operation, the MLSS of each compartment slowly increased, and finally reached a stable state. Through this test, the startup process of the DASB reactor under ambient temperature conditions is clarified, and the operation is better controlled to optimize the process. In addition, this study provides an important basis for the treatment of organic wastewater in DASB reactor.
