一、常见工艺：

二.除氨氮树脂应用：

垃圾渗滤液一般氨氮较高，常采用生化工艺处理，生化工艺可以将绝大部分氨氮去除掉，但其处理深度及稳定性，所以，目前运营中的垃圾渗滤液项目生化后出水氨氮含量普遍高于生化设计值。目前较多地方采用表3的标准（8ppm），所以从2017年开始，我司除氨氮树脂大规模应用在垃圾渗滤液液上面，用于接力处理氨氮，将之处理到1个ppm以下。

目前常用于两个环节，一是反渗透膜后接除氨氮树脂，二是膜浓缩液上蒸发器后的冷凝水后接除氨氮树脂。

   除氨氮专用强酸型阳离子交换树脂

Tulsion® T-42H 是均粒强酸型阳离子交换树脂，氢H+/钠Na+均粒阳离子交换树脂，适用于高浓度氨氮去除，也可适用于其他浓度氨氮去除系统。

Tulsion® T-42H 强酸型阳离子交换树脂，是一款具有较高的交换容量，同时拥有绝佳的物理及化学稳定品质。可以应用于高浓度氨氮废水处理中，出水氨氮可达到0.1ppm以下。

             Tulsion® T-42H 其均匀的颗粒直径，具有传统的离子交换树脂无法取代的优势，可以减             少 压力损，延长树脂寿命，保证出水品质。
