精密过滤+气态膜分离法处理线路板生产氨氮废水研究

Study on Treatment of Ammonia-nitrogen Wastewater from Circuit Board by Precise Filtration and Gaseous Membrane Separation

介绍了一种线路板企业排放的氨氮废水膜分离法处理装置,该处理装置包括由左向右依次连接设置的一级pH调节系统、精密过滤器、一级膜处理系统、二级pH调节系统、二级膜处理系统。一级pH调节系统和二级pH调节系统结构相同,一级膜处理系统和二级膜处理系统结构相同。该装置减少企业后端污水处理设施氨氮负荷,保障线路板企业氨氮废水达标排放。

This paper describes a circuit board enterprise emissions of ammonia nitrogen wastewater membrane separation processing device,the treatment device consists of left to right in turn connected to set a primary pH adjustment system,precision filter,a membrane treatment system,two The pH adjusting system,the secondary membrane treatment system,the primary pH adjusting system and the secondary pH adjusting system have the same structure,and the primary membrane treatment system and the secondary membrane treatment system have the same structure.The device to reduce the enterprise back-end sewage treatment facilities ammonia nitrogen load,to ensure that the circuit board enterprises ammonia nitrogen wastewater discharge standards.
