【摘要】 介绍利用浓硫酸处理碱减量废水的方法。通过分析涤纶织物碱减量废水污染物组分,用硫酸中和 废水中的残余烧碱,然后使聚酯水解物钠盐变成酸式结构,且水溶性下降而析出,并与低聚物一起沉淀,经压 滤后排出清水,大幅度降低COD值,且得到可再利用的白色废渣。更多还原

【Abstract】 Pollutant analysis of polyester alkali deweighting wastewater is carried out. The measure to dispose the wastewater is put forward: the first, vitriol oil is used to neutralize the residual soda; the second, polyester hydrolysate sodiumis turned to acidic structure which has low water solubility, so it can emanate and precipitate with oligomers; finally, via pressing and filtering, the white recycled offscum and clean water are obtained.更多还原
