开发研制最优工艺过程及设备以减少生产中向环境排放的废料,推行隔膜工艺以净化污水,这些在国民经济各部门的应用日益发展。粘胶短纤及长丝在生产中形成了大量洗涤废水,每升水中含有2～5g硫酸盐,通常要求排放的废水中的硫酸盐含量最终应恢复到生态环境中的初含量。为此首先要制定出洗涤水脱盐流程,解决该问题的方向之一即是用电渗析法处理排放水。特维勒斯克(TBEPCKNN)的化纤生产
The development of optimal process and equipment to reduce emissions to the environment during production, the implementation of diaphragm technology to purify the sewage, these sectors in the national economy is growing. Viscose staple fibers and filaments in the production of a large number of washing wastewater, per liter of water contains 2 ~ 5g sulfate, usually require the discharge of sulfate in the final content of the wastewater should be restored to the ecological environment. To this end, we must first develop a washing water desalination process, one of the ways to solve this problem is to treat the discharge water by electrodialysis.
