摘要
对厌氧折流板反应器（ＡＢＲ）处理城市污水与垃圾渗滤液混合废水过程中的水解酸化作用及污泥特性进行了研究。结果表明，ＡＢＲ可有效地改善混合废水的可生化性。进水ＢＯＤ５／ＣＯＤ为０．２～０．３时，出水ＢＯＤ５／ＣＯＤ可提高至０．４～０．６；容积负荷达４．７１ｋｇＣＯＤ／（ｍ３·ｄ）时，形成沉降性能良好、粒径为１～５ｍｍ的棒状颗粒污泥，各隔室中的污泥浓度为２０～３８ｇ／Ｌ。混合废水经ＡＢＲ的预处理，大大促进了废水进一步好氧处理的运行稳定性。
A study on hydrolysis and acidogenesis actions and the characteristics of sludge in an anaerobic baffled reactor (ABR) treating a mixed wastewater of landfill leachate and municipal wastewater was described in this paper. The results showed that ABR could effectively improve the biodegradability of the mixed wastewater. The ratio of BOD 5/COD of the mixed wastewater was increased to 0.4～0.6 form its initial value of 0.2～0.3.The fine settleable granular sludge with a size of 0.5～5 mm was formed in the ABR when the organic load reached 4.71kgCOD/(m 3·d).Concentrations of granular sludge in different compartments of ABR Were found in the range of 20～38 g/L. After the mixed wastewater was pre-treated by ABR, the operational stability of aerobic process was promoted.
