介绍了邯钢二冷轧厂废水处理系统的工艺设计、特点与运行效果。废水处理系统根据分质处理原则,设计4条主处理流程协同处理,以电气浮、涡凹气浮、超滤、MBR、A/O生化工艺为核心工艺。经系统调试合格后正常投产,其运行效果稳定,出水水质达标,运行费用较低。 The process design, characteristics and operating results of Wastewater Treatment System of Handan Iron and Steel Second Cold Rolling Mill are introduced. Wastewater treatment system according to the principle of quality control, the design of the four main processing processes co-processing, floating, cavitation flotation, ultrafiltration, MBR, A / O biochemical processes as the core process. The system commissioning after the normal operation, the operation effect is stable, effluent quality standards, lower operating costs.
