對(duì)"混凝+活性炭吸附"聯用工(gōng)藝處理(lǐ)煤化(huà)工(gōng)高(gāo)含鹽廢水(shuǐ)進行了試驗研究,考察了相(xiàng)關工(gōng)藝參數對(duì)COD去(qù)除效果的(de)影響;選用聚合硫酸鐵(tiě)(PFS)為(wèi)混凝劑,當PFS投加量為(wèi)0.5 g/L,聚丙烯酰胺助凝劑投加量10 mg/L,廢水(shuǐ)初始pH為(wèi)8.69時(shí),COD去(qù)除率達到29.0%;選用柱狀活性炭為(wèi)吸附劑,當活性炭投加量60 g/L,廢水(shuǐ)初始pH為(wèi)7.40,吸附時(shí)間(jiān)120 min時(shí),COD去(qù)除率為(wèi)70.1%,出水(shuǐ)COD小(xiǎo)于80 mg/L;結果表明(míng),該工(gōng)藝可以有(yǒu)效去(qù)除煤化(huà)工(gōng)高(gāo)含鹽廢水(shuǐ)COD.
