Abstract

Abstract

Driven by the strategy and policy of national sewage and wastewater resource, zero liquid discharge of industrial wastewater has become an inevitable trend. As a heavy industry, the circulating cooling wastewater from cement plants is characterized by high salt content, high condensate ratio and high concentration of calcium and magnesium ions. Scientific and effective desalination treatment must be carried out before discharge and reuse to reduce the environmental pollution. The traditional treatment process has many deficiencies, such as large dosage, unstable operation, and large amount of residual chemical sludge which is easy to cause the secondary pollution. In this study, the technical idea of advanced treatment of wastewater by coagulation sedimentation+reverse osmosis+electrodialysis process was proposed. The function and characteristics of electrodialysis unit in the treatment of high salt wastewater were discussed, and its operation effect was investigated. Through the operation of a cement plant in Shaanxi province for more than 2 months, the results showed that the desalination rate of electrodialysis system was 24.7%, the concentration ratio of electrodialysis system was 14.6 times, the average conductivity and water yield of the concentrate liquid were 147.7 mS/cm and 0.07 m³/h, respectively.
