摘要

以磷矿粉为原料

用超声波分散、酸浸

碱法制备复合聚磷氯化铝

并研究其优化制备条件和水处理混凝性能。研究内容包括：盐酸投加量、温度、加热时间、磷铝摩尔比对产物中氧化铝含量的影响

对产物进行红外分析、电镜分析

并将产物用于生活污水处理试验。研究结果显示：加盐酸量为48 mL

温度为100℃

加热时间为180 min

磷铝摩尔比为020时

产物中氧化铝含量最高

红外分析证明了产物的结构

电镜分析表明产物表面积较大

且凝聚态强

将试验制备的聚磷氯化铝用于处理生活污水时

当混凝剂投加量为032 mL/L

pH值范围处于75～100

快速搅拌时间为40 min时

COD去除率可达到731%

浊度去除率可达到990%。

Abstract

The optimal preparation conditions and coagulation/flocculation performance of polymeric phosphate-aluminum chloride (PPAC) were measured. Some parameters such as acid dosage

temperature

reaction time and P/AL molar ratio were investigated. Also

infrared spectroscopy and scattering electron were used to characterize the structure of PPAC. In addition

the coagulation/flocculation process was carried out for wastewater treatment. It is shown that the maximum alumina content is achieved when acid dosage

temperature

time and P/AL molar ratio are 48 ml

100 ℃

180 min and 02 respectively; infrared spectroscopy analysis fits well with the product structure; scattering electron analysis suggests a large surface area and a strong condensed state for PPAC; the removal efficiency of 731% and 990% for COD and turbidity respectively are obtained when coagulant dosage

pH value and agitation speed are 032 ml/L

75~100 and 40 min respectively.
