采用混凝法对水性油墨废水进行处理,探讨了混凝剂种类及投加量、混凝最佳pH值、助凝剂种类及投加量等因素对混凝效果的影响。结果表明,当混凝剂硫酸亚铁投加量为200 mg/L,助凝剂聚丙烯酰胺投加量为2.5 mg/L,pH值为5,沉降时间为40 min时,处理后的废水色度去除率达97%以上,COD去除率达92%以上。
採用混凝法對水性油墨廢水進行處理,探討瞭混凝劑種類及投加量、混凝最佳pH值、助凝劑種類及投加量等因素對混凝效果的影響。結果錶明,噹混凝劑硫痠亞鐵投加量為200 mg/L,助凝劑聚丙烯酰胺投加量為2.5 mg/L,pH值為5,沉降時間為40 min時,處理後的廢水色度去除率達97%以上,COD去除率達92%以上。
채용혼응법대수성유묵폐수진행처리,탐토료혼응제충류급투가량、혼응최가pH치、조응제충류급투가량등인소대혼응효과적영향。결과표명,당혼응제류산아철투가량위200 mg/L,조응제취병희선알투가량위2.5 mg/L,pH치위5,침강시간위40 min시,처리후적폐수색도거제솔체97%이상,COD거제솔체92%이상。
Coagulation process was used to treat water -based ink wastewater. The coagulation effects of the types and dosage of coagulants, the pH value, and the types and dosage of coagulation aid were investigated. The results indicated that when wastewater＇s pH value was 5, the dosage of FeSO4 was 200 mg/L, the dosage of PAM was 2.5 mg/L, and sedimentation time was 40 min, and the color and COD removals can reach 97% and 92%, respectively.
