Abstract
(EN)
A method for controlling pipe corrosion and odor, comprising: adding ferrate into a piping system (such as a sewage pipe, a rainwater pipe and a reclaimed water pipe) having a corrosion and odor problem; and determining an input amount and input frequency for the ferrate according to a water flow amount and a water entry mode.
(FR)
L'invention concerne un procédé de commande de corrosion et d'odeur de tuyau, comprenant les étapes consistant à : ajouter du ferrate dans un système de tuyauterie (tel qu'un tuyau d'égout, une canalisation d'eaux pluviales et un tuyau d'eau récupérée) ayant un problème de corrosion et d'odeur ; et à déterminer une quantité et une fréquence d'entrée pour le ferrate selon une quantité d'écoulement d'eau et un mode d'entrée d'eau.
(ZH)
一种控制管道腐蚀和嗅味的方法,通过在含有腐蚀和嗅味问题的管道系统(如污水管道,雨水管道,中水管道等)中加入高铁酸盐,根据水流量和进水模式,确定高铁酸盐的投放量和投加频率。
