摘要
本文研究了采用高负荷上流式厌氧污泥床(UASB)反应器处理酒糟污水的工艺性能。试验结果表明:在COD 容积负荷高达48.25 kg/(m^3·d)、污泥负荷(以挥发性污泥浓度计)高达5.42 kg/(kg·d)、水力停留时间为11 h的情况下,反应器仍能稳定运行,并可保证有大于80%的COD 去除率,同时可获得12.53 l/(l·d)的甲烷产气率。厌氧出水中的硫化物可通过空气氧化脱除,最终出水可用于农田灌溉。
This article describes the technological characteristics of winery was-tewater treatment using a high loading UASB reactor.The results showthat in ease of COD space loading rate and sludge loading rate up to 48.25kg/(m^3· d) and 5.42 kg/(kg·d),respectively,corresponding to hydraulic retent-ion time 11h,the system is fairly stable.The removal rate of COD reachesover 80% and 12.53 L/(L·d) of methane gas output rate is achieved.Thesulfide in anaerobic effluent can be removed by air oxidation.The finaleffluent can be used to irrigate.
