摘要
采用全自动净水器+超滤组合工艺,对山西省某水泥厂排放废水进行预处理,联合后续反渗透工艺以实现中水回用,处理水量为28 t/h。经该工艺处理后,最终出水水质良好,浊度由34.1 NTU降至0,总硬度由3 160 mg/L降至40 mg/L,可直接回用于该水泥厂余热发电循环水补充用水,出水量为20 t/h,回用率达75%。工程实践表明,该联合工艺可实现对水泥厂排放废水的深度处理和高质回用。
The combined process,full automatic purifier＋ultra-filtration,has been used for the pretreatment of dis-charged wastewater from a cement plant in Shanxi Province. Then the subsequent reverse osmosis process has been used for realizing recycled water reuse. Its treatment capacity of water is 28 t/h. The quality of the final effluent is favorable. For example,the turbidity drops from 34.1 NTU to 0,and total hardness drops from 3 160 mg/L to 40 mg/L. Therefore,it can directly be reused as make-up water for the excess heat power circulating water in the cement plant. The water yield is 20 t/h,and the rate of reuse up to 75%. It has been proved by practical application that the com-bined process could guarantee that the advanced treatment of discharge wastewater from cement plants is stable and its recycle quality is high.
