摘要

  • 摘要: 针对颜料废水有机物浓度含量高、水质波动大、可生化性差等特点，实验采用了UASB-PACT（powdered activated carbon treatment）组合工艺在常温下对颜料废水进行中试研究。实验共进行了119 d，分2个阶段进行，第1阶段为低浓度运行阶段，进水COD逐步提升至3 000 mg·L-1左右，经过36 d的运行，系统出水COD可稳定保持在500 mg·L-1以下，UASB、PACT反应器对COD的平均去除率分别为37.0%和80.5%；第2阶段为负荷提高阶段，共运行了83 d，UASB、PACT反应器对COD的平均去除率分别为53.9%和81.7%。76 d后在平均进水浓度为6 207.75 mg·L-1的条件下，出水COD -1。在工程应用阶段，经过6个月的调试，在进水量1 920 m3·d-1、COD为5 000 mg·L-1的条件下，UASB反应器的出水COD -1，PACT出水COD在300~500 mg·L-1之间波动，去除率分别为50.9%和75.3%。实验结果表明，针对有机颜料废水，采用UASB-PACT组合工艺能够达到很好的处理效果，出水满足《污水排入城镇下水道水质标准》（CJ 343-2010）中A级排放要求。
    Abstract: Pigment wastewater is characterized by a high amount of organic content, low rate of biological degradation, and significant fluctuation in quality. A pilot study on the treatment of pigment wastewater was conducted at room temperature by using a combined process of UASB-PACT (which involves adding powdered activated carbon to a normal activated sludge system). The two-stage experiment was carried out over 119 days. The respective efficiencies of COD removal from the effluent via UASB and PACT were 37.0% and 80.5% in the first stage, and the concentration of organics in the effluent was below 500 mg·L-1 when the COD of the influent increased to 3 000 mg·L-1. The respective average efficiencies for COD removal from the effluent via UASB and PACT were 53.9% and 81.7% in the second stage. Further, the concentration of organics in the effluent was below 500 mg·L-1 when the average COD influent was 6 207.75 mg·L-1. In the stage of engineering application, the combined process was debugged over six months. When the water ingress was 1 920 m3·d-1 and the COD was 5 000 mg·L-1, the respective efficiencies for COD removal from the effluent via UASB and PACT were 50.9% and 75.3%, and the concentration of organics in the effluent was in the range of 300 to 500 mg·L-1. The experimental results showed that the combined UASB-PACT process is an effective approach for treatment of pigment wastewater.
