EFFECT OF ELECTROCHEMICAL PRETREATMENT ON PRODUCTION OF VOLATILE FATTY ACIDS BY CO-ANAEROBIC FERMENTION OF FOOD WASTE AND SEWAGE SLUDGE

  • 摘要: 利用餐厨垃圾-污泥耦合厌氧发酵产挥发性脂肪酸(volatile fatty acids,VFAs)具有广泛的经济和应用价值。本实验考察了在1 V电化学预处理条件下,研究餐厨垃圾占比(空白对照,0%,5%,10%,质量分数)对厌氧发酵生成VFAs产量的影响,从而得出产VFAs的最优条件。研究表明:经过60 min 1 V电化学预处理后,随着餐厨垃圾占比从0%增加到10%,水体中溶解性COD浓度随时间变化迅速增加,最高可达到969~1266 mg/L,随着厌氧发酵的进行转化成VFAs。其中,当餐厨垃圾占比为10%时,VFAs在15 d内最高浓度可达到132.2 mg/L。实验结果表明,电化学预处理可改善餐厨垃圾-污泥特性,加快厌氧发酵过程,同时餐厨垃圾可增加污泥中有机质含量,增加VFAs产量,实现餐厨垃圾-污泥产VFAs的资源化利用途径。
