1脱硫废水处理的必要性石灰石－石膏湿法脱硫系统的脱硫废水，由于Cl-和含盐量较高，无法在电厂内部综合利用，且很难深度净化处理，成为电厂难处理的废水。据了解，目前脱硫废水主要应用于煤场喷洒、干灰加湿、湿渣冲洗等，但上述方法均无法保证完全消化脱硫废水，且给现有工艺系统的安全稳定运行带来隐患。考虑到氯离子对脱硫效率的影响，脱硫废水氯离子浓度一般控制在2mg/l以内，据电厂调研，目前大多数电厂控制在12mg/l以内，远大于以上排放标准。

与其他膜分离过程比较，纳滤的一个优点是能截留透过超滤膜的小分子量的有机物，又能透析反渗透膜所截留的部分无机盐——也就是能使“浓缩”与脱盐同步进行。NF膜分离需要的跨膜压差一般为.5～2.MPa，比用反渗透膜达到同样的渗透能量所必须施加的压差低.5～3MPa。在同等的外加压力下，纳滤的通量要比反渗透大得多，而在通量一定时，纳滤所需的压力则比反渗透的低很多。所以用纳滤代替反渗透时，“浓缩”过程可更有效、快速地进行，并达到较大的“浓缩”倍数。

”在追求氮磷向着更高去除水平发展的同时，JamesBarnard也提到了当前的污水处理正由磷去除向着磷回收的目标发展，消化污泥的滤液中含有高浓度的氮磷，以鸟粪石或其他形式的磷回收技术已经在全球各地开始实践，鸟粪石是一种高价值的缓释磷肥，具有良好的市场价值，在过去几年里肥料的价格一直在不断上涨，这使得磷回收的呼声日渐强烈。因为磷是地球上有限的资源，是生命活动的必须元素，目前全球的磷矿存量主要分布于几个少数。
1脱硫废水处理的必要性石灰石－石膏湿法脱硫系统的脱硫废水，由于Cl-和含盐量较高，无法在电厂内部综合利用，且很难深度净化处理，成为电厂难处理的废水。据了解，目前脱硫废水主要应用于煤场喷洒、干灰加湿、湿渣冲洗等，但上述方法均无法保证完全消化脱硫废水，且给现有工艺系统的安全稳定运行带来隐患。考虑到氯离子对脱硫效率的影响，脱硫废水氯离子浓度一般控制在2mg/l以内，据电厂调研，目前大多数电厂控制在12mg/l以内，远大于以上排放标准。

与其他膜分离过程比较，纳滤的一个优点是能截留透过超滤膜的小分子量的有机物，又能透析反渗透膜所截留的部分无机盐——也就是能使“浓缩”与脱盐同步进行。NF膜分离需要的跨膜压差一般为.5～2.MPa，比用反渗透膜达到同样的渗透能量所必须施加的压差低.5～3MPa。在同等的外加压力下，纳滤的通量要比反渗透大得多，而在通量一定时，纳滤所需的压力则比反渗透的低很多。所以用纳滤代替反渗透时，“浓缩”过程可更有效、快速地进行，并达到较大的“浓缩”倍数。

”在追求氮磷向着更高去除水平发展的同时，JamesBarnard也提到了当前的污水处理正由磷去除向着磷回收的目标发展，消化污泥的滤液中含有高浓度的氮磷，以鸟粪石或其他形式的磷回收技术已经在全球各地开始实践，鸟粪石是一种高价值的缓释磷肥，具有良好的市场价值，在过去几年里肥料的价格一直在不断上涨，这使得磷回收的呼声日渐强烈。因为磷是地球上有限的资源，是生命活动的必须元素，目前全球的磷矿存量主要分布于几个少数。
