考察了阻聚剂类型及投加量、pH值、反应时间等条件对高浓度强酸性含磷催化剂助剂废水(以下简称废水)处理效果的影响。结果表明:向废水中直接加入NaOH,在体系pH值升至2~3时会发生强力自聚反应,以强电解质盐为阻聚剂,可以利用盐效应阻止自聚反应的发生;在室温环境下,以MgCl2为阻聚剂,投加量为10 g/L时,调节废水pH值为5,反应60 min,3种废水中总磷质量浓度由10.2,15.1,24.8 g/L依次降至3.02,3.58,3.91 mg/L,总磷去除率达到99%以上。
- Abstract:
-
The effects of types and dosages of polymerization inhibitors, pH value, reaction time, and other condition on the treatment efficiency of high concentration strongly acidic phosphorus containing catalyst additive wastewater (hereinafter referred to as wastewater) were investigated. The results showed that adding NaOH directly to the wastewater would cause a strong self polymerization reaction when the pH value of the system increased to 2-3,while using strong electrolyte salts as polymerization inhibitors could prevent the occurrence of self polymerization reaction through salt effect. At room temperature, using MgCl2 as a polymerization inhibitor with a dosage of 10 g/L, adjusting the pH value of the wastewater to 5, and reacting for 60 min, the total phosphorus mass concentration in the wastewater decreased from 10.2, 15.1, and 24.8 g/L to 3.02, 3.58, and 3.91 mg/L, respectively, with a total phosphorus removal rate of over 99%.
