我国地下水除铁技术已经有了很大发展,接触氧化过滤除铁技术已在很多地下水除铁水厂推广使用。对于接触氧化法除铁,提高滤速、增加产水量是实现高效率去除水中铁质的重要措施。但是滤速的提高是否影响过滤后的水质,对滤层水头损失增长,滤池的工作周期有何影响,这些问题是高滤速
China’s groundwater iron removal technology has made great progress. The technology of contact oxidation and iron removal has been popularized in many groundwater iron and iron plants. For removing iron by the contact oxidation method, increasing the filtration rate and increasing the water production is an important measure to achieve high-efficiency removal of iron in water. However, whether the increase of the filtration rate affects the quality of the filtered water, the increase of the head loss of the filter layer, and the influence of the filter’s working cycle, these problems are high filtration rates.
