    摘要:

    以馬鈴薯淀粉為原料,，3-氯-2-羥丙基三甲基氯化銨為陽(yáng)離子醚化劑,，采用預(yù)干燥干法制備出取代度為0.3903的高取代度陽(yáng)離子變性淀粉絮凝劑,，并將其與聚合硫酸鐵復(fù)配使用,。通過(guò)正交試驗(yàn)優(yōu)化出最佳絮凝工藝：陽(yáng)離子淀粉質(zhì)量分?jǐn)?shù)為0.15%,、聚合硫酸鐵質(zhì)量分?jǐn)?shù)為0.15%,，廢液初始pH值為7.0,。經(jīng)過(guò)絮凝處理的馬鈴薯淀粉生產(chǎn)廢液的化學(xué)需氧量去除率(COD)為64.31%。

    Abstract:

    The quaternary amino groups containing cationic starch with the degree of substitution 0.3903 was prepared via the reaction of potato starch with 3-chloro-2-hydroxypropyl-trimethyl ammonium chloride using predrying dry process. Then the cationic starch (CS) and poly ferric sulfate (PFS) would be used to treat potato starch waste water. And the cleaning efficiency of the chemical oxygen demand (COD) in the wastewater was studied by changing the experiment conditions. Though the orthogonal test, the optimal conditions were as follows: CS addition 0.15%, PFS addition 0.15%, initial reaction pH 7.0. The removal rate of COD was 64.31%.
