聚天冬氨酸用于冲灰水闭路循环的阻垢试验研究

Gongye shui chuli, 2004
对冲灰水回用系统的结垢原因进行了分析,选用无毒、具有生物降解性能的聚天冬氨酸作为阻垢剂用于华能岳阳电厂的冲灰水回水系统。实验室试验及现场的运行结果表明,该阻垢剂对冲灰水回用系统具有较好的阻垢效果。利用扫描电镜及X-衍射对其阻垢机理进行了研究。

双膜法处理印染废水及其回用的工程应用

Gongye shui chuli, 2010
采用双膜法工艺处理某印染厂印染废水并回用,结果表明,系统运行良好,对COD的去除率达到了99%以上,对浊度、色度的去除率均接近100%,反渗透对盐分的去除率在98%以上。产水水质及水量稳定,满足回用印染要求,工程投资回报率高,经济和环境效益显著。
