摘　　要：针对有机膨润土生产企业产品种类繁多,废水排放成分复杂,水质波动大,COD浓度高、SS浓度高、硬度高,带高温的特点,采用“分类收集、分质处理”的设计思路,针对中高浓度废水使用智能配水-混凝气浮的方式实现纳管排放,针对低浓度废水采用预处理-超滤-反渗透的组合工艺实现车间用水回用。工程实践表明,设计思路可行,废水处理和回用系统能满足长期运行稳定,外排水水质稳定达标,回用水水质满足生产用水要求。In view of the organic bentonite production enterprise product variety, wastewater composition is complex, water quality fluctuation is large, high concentrations of COD, high SS concentration, high hardness, with the characteristics of high temperature, using "classified collection with classified treatment" design train of thought, in view of the high concentration in the wastewater using Intelligent water distribution, coagulation air floatation process. The combined process of pretreatment, ultrafiltration and reverse osmosis was to realize the reuse of workshop water for low concentration wastewater.The engineering practice shows that the design idea is feasible, the wastewater treatment and reuse system can meet the long-term operation stability, the external drainage water quality is stable, and the water quality of reuse water can meet the requirements of production water.
