点击翻译按钮获取中文摘要

In small factory such as plating industry, treatment of fluoride in waste water is one of the important issues. In this research project, we have developed 1) functional material for water treatment based on "nano-biomimetic reaction of dicalcium phosphate dihydrate (DCPD)", 2) on-site monitoring process for effluent, 3) effect of introducing novel water treatment system for company.Major results in the project are as follows; 1) Development the DCPD having various particle shape that suitable for water treatment, 2) Surface modification by hydroxyapaite (HA) on surface of the DCPD particle, 3) On site monitoring of fluoride in effluent, and 4) technical issues for waste water treatment in small industrial sites.
