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020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032 mL/L
pH值范围处于75~100
快速搅拌时间为40 min时
COD去除率可达到731%
浊度去除率可达到990%。
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 02 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 731% and 990% for COD and turbidity respectively are obtained when coagulant dosage
pH value and agitation speed are 032 ml/L
75~100 and 40 min respectively.
