【摘要】：利用稀土-殼聚糖復(fù)合絮凝劑處理制革廢水,探討了復(fù)合絮凝劑處理制革廢水的處理工藝及最佳處理?xiàng)l件,采用單因素試驗(yàn)法研究了復(fù)合絮凝劑的濃度、p H、溫度、攪拌時(shí)間對(duì)制革廢水中總鉻、化學(xué)需氧量(COD)、濁度的去除率的影響。結(jié)果表明:復(fù)合絮凝劑處理制革廢水的最佳條件為:稀土-殼聚糖復(fù)合絮凝劑濃度為0.25g/L,p H值為7,溫度為30~40℃,攪拌時(shí)間為10~20min,與聚合氯化鋁、聚合硫酸鐵相比,殼聚糖復(fù)合絮凝劑在廢水處理中表現(xiàn)出明顯優(yōu)勢(shì)。
[Abstract]:Leather wastewater was treated with rare earth and chitosan complex flocculant. The treatment process and optimum treatment conditions of tannery wastewater were discussed. The concentration and temperature of compound flocculant were studied by single factor experiment. The effect of stirring time on the removal rate of total chromium, COD and turbidity in tannery wastewater. The results showed that the optimum conditions for the treatment of tannery wastewater were as follows: the concentration of rare-earth / chitosan compound flocculant was 0.25g / L ~ (-1) H = 7, the temperature was 30 ~ 40 鈩，
