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.
Study the effects of adding sodium polyacrylate on the properties of water-absorption and water-retention of composting production. The result shows that,PAAS can improve the sludge structure obviously; the water absorbency of composting production adding PAAS can reach 5. 97 m L·g- 1,better than composting production without PAAS; when mixing PAAS composting production with field soil at application ratio,the water-retention obeys the zero-order reaction,and its calculation result by the models are consistent with the evaporation experiments.
