摘要
采用新型以微气泡发生器为核心的微气泡气浮工艺与普通压力溶气气浮工艺对比,对含油餐饮废水进行预处理,考察了在不同絮凝剂投药量、水力停留时间、工作压力、回流比条件下,两种工艺对水中主要污染物油,有机物(COD)的去除效率。结果表明,在相同或相近条件下,新型微气泡气浮工艺对水中污染物的去除率高于普通溶气气浮工艺。
A comparative study was carried up to investigate pollutants removal efficiency in oil - bearing restaurant wastewater by new type micro -bubble air flotation and traditional dissolved air flotation. The impact of the main factors such as the dosage of coagulant, hydrodynamic residence time （HRT）, pressure （P） and regurgitant （R） were discussed. The results showed that pollutants removal efficiency of the new type micro - bubble air flotation is higher than the traditional dissolved air flotation process.
