随着工业的发展,环境保护已引起人们的极大注意,因而电镀废水的处理已成为急待解决的问题。对于在城市中的中小型电镀车间来讲,由于厂房而积窄小,很难采用化学处理、离子交换等方法来处理废水。为了节约用水,解决水力能源问题,我们根据国内外文献和一些单位的经验,将“超滤技术”和“逆流漂洗”技术加以结合,自行设计了一条简易省水的镀锌废水封闭循
With the development of industry, environmental protection has drawn great attention. Therefore, the treatment of electroplating wastewater has become an urgent problem to be solved. For the small and medium-sized electroplating workshops in the city, it is difficult to use chemical treatment, ion exchange and other methods to treat the waste water due to the small size of the workshop. In order to save water and solve the problem of hydraulic energy, according to the domestic and foreign literatures and the experiences of some units, we combined “ultrafiltration technology” and “countercurrent rinsing” technology to design a closed water-saving galvanized wastewater
