| Abstract: | CAST/dual membrane system(CMF+RO) was used for iron and steel plant wastewater treatment and reuse under the conditions of multi-source water.The non-conventional water sources,such as production wastewater,domestic sewage,rainwater and so on were treated and used as production circulating water and make-up water.Through the on-site monitoring of the system treatment effect and operation parameters at different stages,the problems appeared in the early commissioning stage were analyzed,and the effective adj... |
