摘要
采用实验室筛选的高效混合酵母菌菌群构建了小型中试酵母菌生物膜反应系统。该反应系统与水解酸化和炉渣过滤装置进行工艺组合后,在现场实际废水条件下连续运行116d,在进水COD为330～1875mg/L、色度为100～500倍、SS为110～728mg/L的情况下,不需要添加额外碳源,出水COD为100～155mg/L、色度为20～40倍、SS为26～92mg/L,COD、色度、SS去除率最高分别达到91.2%、95.0%、96.4%,实现废水达标排放,与传统印染废水处理工艺相比,节约处理成本约1.09元/t。
The yeast biofilm reactor has been constructed by using highly efficient mixed yeast screened by the laboratory. After the reaction system was combined with hydrolysis-acidification and slag filtration reactors, it has run for 116 d continuously on site. When the influent COD is 330-1 875 mg/L, chroma 100-500 dilution times, and SS 110-728 mg/L, without adding any extra carbon source, the effluent COD is 100-155 mg/L, chroma 20-40 times, SS 26-92 mg/L, the removal rates of COD, chroma, and SS are 91.2%, 95.0% and 96.4% respectively, meeting the requirements of the second grade standard of water discharge. Compared with the traditional printing and dyeing wastewater treatment processes, about 1.09 CNY/t of water could be saved by this process.
