摘要
台湾某净水厂采用超滤膜(UF)及低压反渗透膜(LPRO)组合深度处理技术,以去除水中重金属离子、悬浮固体、胶体颗粒、藻类、寄生孢子、病毒等危害人体的物质,同时节省了化学药剂用量并减少了污泥产量。运行表明,双膜法可以有效提高出水水质、利于工艺自动化且节省空间,具有很好的工程效果。
A waterworks in Taiwan adopts the combined advanced treatment technology of ultrafiltration （UF） membrane and low pressure reverse osmosis （LPRO） membrane to remove heavy metal ions, suspended solids （ SS）, colloidal particles, algae, parasitic spores, viruses and other substances harmful to human health in water. At the same time, the chemicals dosage is saved, and the sludge production is reduced. The operation shows that the dual membrane water treatment can effectively enhance the water quality, it is favorable for automation and space-saving, and has good engineering effect.
