不同絮凝剂处理焦化废水的研究

Research on treatment of cocking wastewater by different flocculants

相同条件下用 3种常用的聚硅酸盐类絮凝剂 (PASS,PZSS,PFSC)和高铁酸钠 (Na2 Fe O4 )处理焦化废水 ,实验结果表明 ,除聚硅酸铝在去浊方面优于高铁酸钠外 ,高铁酸钠无论在 CODCr。

Cocking wastewater was treated by PASS,PZSS,PFSC and sodium ferrate, respectively. Experimental result indicated, ferrate was superior than the other flocculants, either in the COD\-\{Cr\} removal efficiency or in the chroma and SS removal efficiencies. Only the PASS was better than the sodium ferrate in the turbidity removal efficiency. \;
