厌氧-好氧处理变性淀粉生产废水工程实例

Engineering example of metamorphic amylum production wastewater treatment by anaerobic biological process and aerobic biological process

利用膨胀颗粒污泥床(EGSB)和活性污泥好氧处理工艺相结合处理高浓度变性淀粉生产废水,处理水质可达到国家污水综合排放一级标准。工程实践表明该工艺具有投资与占地面积少,运行效果稳定,可回收能源等优点,具有很高推广价值。

EGSB (expansile granular sludge bed) is used in combination with anaerobic biological process and activated sludge aerobic process to treat highly concentrated amylum production wastewater. The water quality of the final effluent can meet the First Grade of the National Effluent Discharge Standard. The engineering example shows that this process has many advantages,such as low investment,less land, and stable treatment efficiency. The sources of energy can be recovered. Therefore,this process has great value of being popularized.
