摘要
攀钢钛白粉厂一车间含铬含砷废水处理工程采用微孔曝气与高效絮凝斜板沉淀相结合为主体的处理工艺。整套处理装置运行稳定,出水TCr、Cr6+、As平均去除率分别达到72.22%、86.18%、47.46%,符合污水综合排放标准(GB 8978-1996)第一类污染物最高允许排放浓度标准。
The chromium and arsenic-contained wastewater treatment project at one workshop of PANGANG titanium dioxide factory used microporous aeration combining the efficient flocculation inclined plate precipitation together as the main body of the process.The process had a stable operation,and the average removal rate of the concentration of TCr,Cr6＋ and As in effluent were 72.22%,86.18%,47.46%,repectively,which met the first kind of pollutant emission concentrations maximum permissible standard of comprehensive sewage discharge standards（GB 8978-1996）.
