混凝法处理餐饮废水的研究 总被引:3,自引:0,他引:3
以聚合氯化铝 (PAC)、聚合硫酸铁 (PFS)和聚丙烯酰胺 (PAM)为混凝剂处理餐饮废水 ,探讨了 PAC、PFS和 PAM在单独和复合使用时的混凝性能。结果表明 ,最佳混凝条件为 :PAC+PAM的用量为 (30 0 +1) m g·L- 1 ,适宜 p H值为 7.5~ 8;PFS+PAM的用量为 (30 0 +2 ) mg· L- 1 ,适宜 p H值为 9左右。阴离子型 PAM与 PAC复合使用的混凝效果最好 ,COD去除率可达 91.4 2 %。 相似文献

The removal of humic acids and phenol from model solution by coagulation and adsorption on powdered activated carbon (PAC) was investigated. A PAX XL-69 polyaluminum chloride was applied as a coagulant. The adsorption of humic acids and phenol on activated carbon for single- and bi- component solutions was studied. It was found that coagulation without PAC addition was less effective than the adsorption-coagulation integrated system. Coagulation enhanced with adsorption on activated carbon was more effective when coagulation was preceded by adsorption than when the two processes were carried out simultaneously. The best results were obtained at pH 7. Phenol and color were removed pletely, UV254 absorbance was reduced by about 99% and COD-Mn was reduced by 81-89%. 相似文献
