摘　　要：针对包钢薄板厂热轧含油废水的水质特征,进行了吸附过滤组合处理技术的适用性试验,采用钢渣吸附剂的吸附试验表明,钢渣投加量5mg·L-1,搅拌20min,静置30min,pH>5的条件下,含油废水中油的去除率大于80%。当进水油类质量浓度为18～22mg·L-1,SS质量浓度为50～66mg·L-1时,8m·3h-1的陶粒滤料处理装置出水含油量为1.8～3.5mg·L-1(平均2.25mg·L-1),悬浮物(SS)质量浓度1.8～5.5mg·L-1(平均3.07mg·L-1),满足生产用水油质量浓度小于10mg·L-1和SS质量浓度小于25mg·L-1的水质要求。For hot rolling oily waster water to present Baogang Sheet Metal factory＇s water quality characteristics, processing on adsorption filter etc. experimental application of process technology. In the experiment of absorption, Steel Residue is used as absorption, the drug amount of Steel Residue is 5mg·L^-1. In condition of pH〉5, oil of oily waster water is adsorbed after is mixed round nearly 20 minutes and is set statically at least 30 minutes, whose removal rate can beyond 80%. When wastewater oil contents amount is 18-22mg·L^-1, SS contents amount is 50-66mg·L^-1,through 8 m^3.h^-1 porcelain granule filter material plant, the out-water lowest oil contents amount is 1.8mg·L^-1,the largest oil contents amount is 3.5 mg·L^-1,averageis 2.25 mg·L^-1.The lowest amount of SS is 1.8 mg·L^-1, the largest amount of SS is 5.5 mg·L^-1, average is 3.07 mg·L^-1.It can satisfy the water quality of manufacture with water oil production〈 10 mg·L^-1 and suspended solids 25 mg·L^-1.
