摘要
本文论述陕西部分黄土台塬区深层地下水六价铬超标的水文地球化学异常,并提出了还原—微絮凝分离的除铬方案,设计了高效低成本的处理工艺。除铬效率达到98％以上,出水水质稳定,各项指标达到饮用水卫生标准。
This paper demonstates the hvdrochemical anomalous areas where the sixvalence chromium content exceeds the standard in deep. groundwater in parts of the loess tableland and water resources. A plan to remove chromium by the reductiontiny agglomerate separation has been selected, and a treatment technique with high efficiency and low cost has been designed. The treatment technique has a 98% efficiency of removing chromium. The water quality is stable and all its indices satisfy the standards for drinking water.
