摘要:
采用固液分离—改良型UASB(上流式厌氧污泥床反应器)厌氧消化—SBBR(序批式生物膜反应器)好氧生化—高效复合絮凝组合工艺处理甘薯燃料乙醇糟液,处理出水各项敏感环境因子均达到国家《污水综合排放标准》(GB8978-1996)一级标准. 在改良型UASB进水COD 36 720~43 890 mg L-1、SS 8 370~11 400 mg L-1条件下,维持反应温度 (35±3) ℃,其容积负荷可达到28.86~34.5 g(COD) L-1 d-1,对COD、SS、VFA去除率分别为92%~93%、89%~91.5%、96%~98%. 在12~30 ℃时,厌氧消化液SS 360~530 mg L-1,BOD 400~530 mg L-1,NH3-N 120~163 mg L-1,S2- 40~50 mg L-1,经两级SBBR好氧生化处理后,分别降低到40~60 mg L-1、250~310 mg L-1、7.2~13.8 mg L-1、低于0.5 mg L-1. 考察3种絮凝剂的混凝效果,以高效复合絮凝剂效果最好,生化处理出水经该絮凝剂混凝处理后,COD、TP和色度分别降低到低于100 mg L-1、0.5 mg L-1和40倍. 图2 表3 参12
Abstract:
A combined process, solid-liquid separation – anaerobic digestion with improved UASB (Up-flow Anaerobic Sludge Bed) – aerobic biological treatment with SBBR (Sequencing Batch Biofilm Reactor) – effective treatment with composite flocculants, which was used to treat wastewater from alcohol fuel production with sweet potato, was studied. It was found that some sensitive environmental pollutants, such as pH, COD, BOD, SS, colority, S2-, NH3-N and TP, could meet the first level requirements of the national integrated wastewater discharge standard (GB8978-1996). At (35±3) ℃, COD and SS in the influent ranged from 36 720~43 890 mg L-1 and 8 370~11 400 mg L-1, respectively, the organic load of the improved UASB were 28.86~34.5 g(COD) L-1 d-1. Removal rates of COD, SS and VFA were 92%~93%, 89%~91.5% and 96%~98%, too. In the range of 12~30 ℃, SS, BOD, NH3-N and S2- were degraded by two-stage SBBR from 360~530 mg L-1, 400~530 mg L-1, 120~163 mg L-1 and 40~50 mg L-1 to 40~60 mg L-1, 250~310 mg L-1, 7.2~13.8 mg L-1 and lower than 0.5 mg L-1, respectively. Of the three investigated flocculants, the effect of the effective composite flocculants was the best. Concentrations of COD, TP and colority in the effluent were lower than 100 mg L-1, 0.5 mg L-1 and 40 times, respectively. Fig 2, Tab 3, Ref 12
