摘要
高含盐废水蒸发处理能实现水和盐分及有机污染物的分离,回收蒸馏水。由于高含盐废水往往含有成垢离子Ca^(2+)、Mg^(2+)以及SiO_2、COD等,因此其蒸发回收面临一系列问题。对高含盐废水蒸发过程中存在的阻垢和蒸馏水水质问题进行了探讨,阐述了目前的阻垢技术以及发展趋势、水质的提升途径及发展方向。
Evaporating high salinity industrial wastewater can realize the separation of water, salt and pol-lutants, and recycle distilled water as well. However, as the said kind of wastewater usually contains SiO2, COD and scaling ions such as Ca2＋, Mg2＋and so on, its evaporation is up against a series of problems. The problems ex-isting in scale inhibition and distilled water recycling during the high salinity wastewater evaporation were dis-cussed, the current scale inhibiting technology and water quality improving measures as well as their development trend and direction were elaborated.
