摘　　要：为了促进两相厌氧消化的水解酸化相中有机物的水解溶出,以生活垃圾中COD、VS溶出量为研究参数,试验研究了动态的喷淋和静态的浸泡对城市生活垃圾有机物水解溶出的影响,厌氧、厌氧与好氧交替作用、厌氧与兼氧交替作用、用UASB出水浸泡以及添加猪粪对有机物水解溶出的影响,试验结果表明采用浸泡方式的溶出效率优于采用喷淋的方式,用UASB出水浸泡具有最佳的溶出效率,有机垃圾和畜禽粪便的联合溶出规律与有机垃圾溶出规律基本一致。The quantity of COD, VS dissolved from municipal solid wastes in acidogenic stage of a two-stage anaerobic digestion system was studied in this paper to promote the organic matter dissolving. The effect on dissolving efficiency of dynamic-spraying, static-soaking, anaerobic condition, ahernativcly anaerobic-aerobic, alternatively anaerobic-facultative anaerobic, soaking with UASB effluent, were studied in this experiment. The result indicated that the method of static-soaking is better than dynamic-spraying, soaking with UASB effluent have the best dissolving efficiency. And the dissolving regularity of organic solid waste combined with animal manure is consistent with that of organic solid waste alone.
