Abstract
There are many hard degraded materials in the papermaking wastewater such as lignin and cellulose[1]. Because of its deeper color and high concentration of small colloidal substances, usually , it needs flocculation process as pretreatment or advanced treatment[2]. In this paper, it used the FeSO4 as flocculant to find the best pH of the reaction and the optimum dosage through detecting the COD, turbidity and chroma of the raw papermaking water and the terminal drainage.
