In this study, bioflocculant produced by Pseudomonas veronii L918 was applied to treat ash-flushing wastewater. The strain L918 could convert the hydrolyzate of peanut hull into bioflocculant, which can effectively reduce the production cost of bioflocculant. The yield of 3.39g/L bioflocculant MBF-L918 was achieved when 300mL/L peanut hull hydrolyzate was used as carbon source. The bioflocculant MBF-L918 contains 77.14% polysaccharides and 4.84% proteins, and the molecular weight (MW) of MBF-L918 is 24.77kDa. Furthermore, MBF-L918 showed good flocculating efficiency of 92.51% to ash-flushing wastewater when 2.83mg/L MBF-L918 was added, and thus achieved the recycling of ash-flushing wastewater. This study reported for the first time that the bioflocculant was produced using peanut hull hydrolyzate and effectively applied in the treatment of coal ash-flushing wastewater.
在本研究中，采用假单胞菌 L918 产生的生物絮凝剂处理冲灰水。该菌株 L918 可以将花生壳水解物转化为生物絮凝剂，从而有效降低生物絮凝剂的生产成本。当使用 300mL/L 花生壳水解物作为碳源时，可获得 3.39g/L 的生物絮凝剂 MBF-L918。MBF-L918 含有 77.14%的多糖和 4.84%的蛋白质，MBF-L918 的分子量（MW）为 24.77kDa。此外，当添加 2.83mg/L 的 MBF-L918 时，MBF-L918 对冲灰水的絮凝效率达到 92.51%，从而实现了冲灰水的循环利用。本研究首次报道了利用花生壳水解物生产生物絮凝剂，并将其有效地应用于处理粉煤灰废水。
