Introduction With the development of science and technology, the rapid rise of industry and the dramatic increase in human activities, especially the wastewater containing chromium emissions produced in the mining, processing, smelting, electroplating, chemical, leather and electronics industries and the emergencies arise of serious environmental pollution , it not only causes pollution of surface water, but also is worsening the contamination of groundwater, even posed a threat on human health and the environment[1,2].
Considering the higher reducibility of iron filing, the availability of raw materials and some characteristics of wastes reuse and “making them profitable”, at the same time, there are less researches of regression analysis on the restoration effect to the groundwater contamination both at home and abroad, this paper tried to study the treatment effect of iron filing, as PRB filling medium, on restoring groundwater with chromium contamination and made regression analysis about it.
