喀麦隆啤酒废水厌氧生物处理的研究 总被引:3,自引:0,他引:3
为了经济有效的控制喀麦降啤酒厂的有机废水污染,选用上流式厌氧污泥床(UASB)反应器,进行了常温厌氧生物处理的试验,结果表明,当地平均气温22.6℃,足以维持反应器的正常工作,但应采取措施降低温度的昼夜波动,糖化废水,发醇废水和啤酒过滤废水混合处理的效果优于各自单独处理,处理混合废水时,适宜的进水COD浓度为11000mg/L左右,适宜的容积COD负荷为12.50g/(L.d),适宜的水力停留时间为1天,在此条件下,COD去除率可达89%以上,容积COD去除率11.76g/(L.d),容积沼气产率4.06L/(L.d),试验证实,采用常温USASB工艺是可行的。 相似文献

Comparative performance of a UASB reactor and an anaerobic packed-bed reactor when treating potato waste leachate 总被引:2,自引:0,他引:2
The results presented in this paper are from studies on a laboratory-scale upflow anaerobic sludge blanket (UASB) reactor and an anaerobic packed-bed (APB) reactor treating potato leachate at increasing organic loading rates from 1.5 to 7.0 g COD/1/day. The hydraulic retention times ranged from 13.2 to 2.8 days for both reactors during the 100 days of the experiment. The maximum organic loading rates possible in the laboratory-scale UASB and APB reactors for stable operation were approximately 6.1 and 4.7 g COD/l day, respectively. The COD removal efficiencies of both reactors were greater than 90% based on the total COD of the effluent. The methane yield increased with increasing organic loading rate up to 0.23 l CH4/g CODdegraded in the UASB reactor and 0.161 CH4/g CODdegraded in the APB reactor. The UASB could be run at a higher organic loading rate than the APB reactor and achieved a higher methane yield. Signs of reactor instability were decreasing partial alkalinity and pH and increasing amounts of volatile fatty acids. The study demonstrated the suitability of the UASB and a packed-bed reactor for treating leachate from potato waste. 相似文献

The Anaerobic Digestion Model 1 (ADM1) was applied to the anaerobic digestion process in an Upflow Anaerobic Sludge Blanket (UASB) reactor treating domestic wastewater. It was evaluated based on data from a 250 L pilot scale reactor. The wastewater influent degradable characteristics and Sludge Retention Time (SRT) were established by several trial and errors simulation to establish appropriate values for parameters not measured experimentally. The model was further verified against varying load experimental results to ensure its usefulness for a wide range of relevant loads. The best fit was obtained using 60 d SRT and parameters recommended for mesophilic conditions, with average experimental values within 10% of the simulated results. The model gave a good estimation of reality and could be applied for feasibility analysis, design and operation of full-scale small plants to be used in rural areas. Kathmandu University (KU) domestic wastewater treatment plant simulation was used as example of such. It showed that a reactor volume of about 4 m3 (6 h HRT) would give reasonable reactor performance with 1.7 m3/d biogas production. 相似文献
