前言采用波纹斜板重力分离器一般能从含油污水中分出大于60微米的油粒,而对较小油粒目前国内外普遍采用投加絮凝剂的溶气浮选和石英砂过滤等工艺。这些方法具有占地面积大、维持费用高、产生二
Preface The corrugated inclined plate gravity separator generally separates the oil particles larger than 60 μm from the oil-contaminated water. However, for small oil particles, the technology of dissolving air flotation and quartz sand filtration by adding flocculant is generally adopted at home and abroad. These methods have a large footprint, high maintenance costs, resulting in two
