软化水处理装置再生含盐废水近零排放技术研究

探讨了供热站软化水处理装置再生过程中产生的高含盐废水的近零排放技术。通过源头控制和工艺改造,实现了含盐废水的有效治理和资源化利用。研究通过对软化器再生过程的优化,将高含盐水和低含盐水进行有效分离与回收处理。通过改进的纯碱软化法除去水中的钙镁离子,高含盐水被循环利用,实现了近零排放。实验结果表明,处理后的水质符合锅炉运行标准,且生成的固体沉淀物可以作为资源进一步利用。此技术不仅减少了环境污染,而且提高了水资源的循环利用率,对于实现工业废水的可持续管理具有重要意义。

This study explores the near zero discharge technology for high-salinity wastewater produced during the regeneration process of softening water treatment plants at heating stations.Through source control and process modification,effective management and resource utilization of the salty wastewater were achieved.The research optimizes the regeneration process of the softener,effectively separating and recycling high-salinity and low-salinity water.By employing an improved soda ash softening method to remove calcium and magnesium ions,the high-salinity water is recycled,achieving near zero discharge.Experimental results indicate that the treated water quality meets boiler operation standards,and the generated solid precipitate can be further utilized as a resource.This technology not only reduces environmental pollution but also enhances the recycling rate of water resources,playing a significant role in the sustainable management of industrial wastewater.
