摘要
采用复极式电凝聚-电气浮方法处理洗衣废水。研究了pH、水力停留时间(HRT)和电流强度对处理过程的影响。结果表明,在较宽的pH范围(pH=4～9)、较短的水力停留时间(HRT=5～10 min)下,悬浮物、阴离子表面活性剂(MBAS)、COD和磷酸盐均可得到有效去除。
A new bipolar electrocoagulation and electroflotation process was developed to treat laundry wastewater. In the process, electrocoagulation and electroflotation were carded out simultaneously in a single reactor. The operating parameters such as initial pH, hydraulic residence time （HRT） and current density were investigated. The design of the reactor made it possible for the effective removal of turbidity, COD, phosphate and surfactant （MBAS） in a wide pH range （4-9） at a short HRT （5- 10 min）.
