Abstract
Microplastics (MPs) and surfactants are generally recognized as emerging contaminants with complicated ecotoxicological impacts. The majority of study data refers to laundry wastewater as a substantial source of MPs and surfactants in the aquatic system, which reaches aquatic environments through sewer discharges even when wastewater treatment facilities retain them. This study focused on releasing and removing contaminants from laundry wastewater, particularly MPs and surfactants. The electrocoagulation method was used to remove the pollutants from laundry wastewater. According to the results, a reference load of 2 kg of synthetic materials releases 92,700 to 1,14,300 synthetic microfibers (MFs). MFs, surfactants, and chemical oxygen demand (COD) removal efficiency are higher at neutral pH. The percentage removal efficiency of MFs, surfactants, and COD was 97.9%, 91.2%, and 86.3%, respectively, at an operating time of 25 min, a current density of 300 A/m2 with optimum power consumption. The total operation cost of laundry wastewater treatment by electrocoagulation was US$0.53 /m3. The readers will gain a complete understanding of the removal of MFs and surfactants from laundry wastewater using the electrocoagulation technique.
微塑料(MPs)和表面活性剂是公认的具有复杂生态毒理学影响的新兴污染物。大多数研究数据表明,洗衣废水是水生系统中MPs和表面活性剂的重要来源,即使废水处理设施保留了它们,它们也会通过下水道排放到达水生环境。本研究的重点是释放和去除洗衣废水中的污染物,特别是MPs和表面活性剂。采用电絮凝法去除洗涤废水中的污染物。根据研究结果,2公斤合成材料的参考载荷释放出92700到114300个合成微纤维(MFs)。中性ph条件下,MFs、表面活性剂和化学需氧量(COD)的去除率较高。在运行时间为25 min、电流密度为300 a /m2、最佳功耗条件下,MFs、表面活性剂和COD的去除率分别为97.9%、91.2%和86.3%。电絮凝法处理洗衣废水的总运行成本为0.53美元/m3。读者将获得使用电絮凝技术从洗衣废水中去除MFs和表面活性剂的完整理解。
