摘要
采用高效厌氧折流板反应器(ABR)、好氧生物脱氮除磷强化生化池(PTA^2O)、高效沉淀池及滤布滤池处理工艺,深度处理生产腐竹排放的高浓度有机废水,出水水质可达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级A标准。ABR结构简单不易堵塞,耐水力和有机物冲击负荷能力强,容积利用率高。PTA^2O池微生物浓度高,高效沉淀池水力负荷高,可减少池容和占地面积;采用新型低通气量曝气软管,可不停产进行反冲洗和更换。ABR-PTA^2O污泥内外回流选用耗能更低的气提回流方式。该工程可实现投资低、占地少、操作简单、节省运行费用的目标。
The combined treatment process of anaerobic baffled reactor（ ABR）, perfect type anae- robic/anoxic/oxic （FFA-2O）and efficient sedimentation tank and cloth filter was used to treat yuba pro- cessing wastewater containing high concentration organic pollutants. The quality of effluent could meet the first level class A of national standard （ GB 18918 - 2002）. ABR has the advantages of simple structure and uneasily plugging, strong hydraulic and organic shock loading capacity and high volume utilization. FFA-2O has the advantages of high biomass content, high hydraulic load of sedimentation tank, decreasing volume and area. Arrangement mode of new type aeration hose with low flux can guarantee backwashing and replacement without stopping tank operation. Gas lift mode for sludge circumfluence with low energy consumption was used in the process of ABR-FFA-2O. The project realized the goal of low investment, less land occupation, simple operation, and low operation cost.
