摘　　要：通过实例阐述硫酸废水循环利用的可行性,以及为确保该过程的正常运行所必要的废水水质控制。举实例说明排放水宜控制偏碱性,循环水宜控制偏酸性(pH4～7)操作,减少污垢生成。The feasibility on circulation & utilization of waste water in production of sulfuric acid is analyzed. In order to ensure stable operation of the process, the water quality should be controlled. Some examples are presented that discharging water is basic, circulation water acidic(pH 4～7), so the fouling reduced.
