【摘要】：研究添加聚丙烯酸钠(PAAS)对堆肥产品的吸水保水性能的影响.研究显示,PAAS能明显改善污泥结构;添加PAAS的堆肥产品吸水倍率可达到5.97 m L·g-1,吸水保水性能都优于未添加PAAS的堆肥产品;将PAAS堆肥产品与田土按堆肥施用比例混合后,其保水反应符合零级反应动力学规律,且模型计算结果与蒸发实验能较好吻合.
[Abstract]:The effect of sodium polyacrylate (Paas) on water absorption and water retention of compost was studied. The results showed that PAAS could obviously improve the sludge structure, the water absorbency of compost added with Paas could reach 5.97 mg ~ (-1), and the water absorbency of composting product was better than that of compost without PAAS, and the composting product of Paas was mixed with field soil according to the proportion of compost application. The water retention reaction accords with the kinetic law of zero order reaction, and the calculated results are in good agreement with the evaporation experiment.
