摘要
研究利用水葫芦的气囊对皂素生产废水进行预处理的效果,通过对比试验,结果表明:干燥的水葫芦气囊在吸附处理综合皂素废水后COD降低率为20%。经水葫芦预处理吸附后皂素废水可生化性提高,厌氧反应产气速率提高1.5倍左右。经过吸附处理后的水葫芦自身的产气效率也有所提高。
The pretreatment of the saponin wastewater by water hyacinth balloon has been studied. Experimental results indicate that the COD removal efficiency is 20% and the pretreatment process can improve biodegradability of the saponin wastewater, the biogas rate is 1.5 times than before, resulting in the benefit of the following biological treatment. After the adsorption, water hyacinth biogas fermenting is also improved.
