摘要

本文旨在研究一项相对较新的技术——高铁酸盐(VI)的在线生成和应用，用于污水处理，从中试到全面试验，在英国南方水务有限公司的海尔沙姆北污水处理厂进行。本文所提出的工作对高铁酸盐(VI)在水和废水处理实践中的使用具有重要影响;高铁酸盐(VI)的在线生产和应用解决了不稳定和不需要运输的问题。通过所开发的系统，目前高铁酸盐(VI)的生成效率高达70%，是比较高的。与高剂量硫酸铁相比，高铁酸盐的投加量在0.01 ~ 0.2 mg Fe 6+ /L之间，达到了同样的除磷目标;这将减少化学品需求和污泥产量，从而降低运营成本，并在处理污水方面节省大量成本。

THE APPLICATION OF FERRATE FOR SEWAGE TREATMENT: PILOT- TO FULL-SCALE TRIALS

This paper aims to study a relative new technology, the online generation and application of ferrate(VI), for sewage treatment, from pilot to full scale trials at Hailsham North Wastewater Treatment Plant of Southern Water Ltd of UK. The work presented in this paper has significant impact on the use of ferrate(VI) in water and waste water treatment practice; the online production and application of ferrate(VI) resolves problems of the instability and needs no transportation. The current efficiency of ferrate(VI) generation was up to 70% through the developed system, which is relatively high. For achieving the same phosphorus removal target from the crude sewage, the ferrate dose required was in a very lower range, 0.01 - 0.2 mg Fe 6+ /L in comparison with high doses of ferric sulphate; these will reduce the chemical demand and sludge production and therefore result in a low operating cost and generate substantial cost saving in treating sewage.
