涂装车间前处理、电泳、传统文丘里喷漆室等均能产生大量废水,随着技术的发展及环保意识的提升,环保法规也对涂装废水处理做了明确的要求,不允许废水中含有重金属,个别区域要求氮磷零排放及废水排放等级提高。为减少废水排放,水回用措施已渐渐成为涂装车间不可避免的选择。

The pretreatment of painting workshop,electrophoresis and traditional Venturi spray booth can produce a large amount of wastewater.With the development of technology and the promotion of environmental awareness,environmental regulations have also made obvious requirements on the painting waste water treatment,which do not allow heavy metals in the wastewater,and some areas require zero emission of nitrogen and phosphorus,and improve the discharge grade of wastewater.In order to reduce wastewater discharge,water reuse has gradually become an inevitable choice in the coating workshops.
