不同污泥源条件下ASBR启动对比研究
Comparative study on ASBR start-up with different seeding sludge source
摘要
Abstract
The key aspect of the practical application of Anaerobic Sequencing Batch Reactor (ASBR) is how to achieve quick startup .In order to reduce the startup time of ASBR ,the effect of inoculation of different sludge on the quick startup were studied .Sludge were inocu‐lated with the secondary settling tank from municipal wastewater treatment plant and anae‐robic sludge in up‐flow anaerobic sludge blanket reactor (UASB) respectively .Take starch as matrix ,after 75 d under condition of constant temperature 35 ℃ ,increasing the influent COD concentration and shortening the hydraulic retention time gradually ,the diameters of sludge were reached 1 .1 mm and 1 .4 mm respectively ,organic load reached 5 .6 kg/(m3 · d) ,COD removal rates were 85% and 90% respectively ,both of the effluent volatile organic acids (VFA) concentrations were less than 200 mg/L ,and the systems were stable ,achieved a quick start‐up of the ASBR .关键词
