随着经济和社会的发展,水资源的微污染问题日益严重,目前的水处理工艺必须考虑到微污染的问题。实验首先寻找传统混凝工艺的条件为pH=6.5~7.5,温度T=17℃~18℃,最佳投加量6.384mg/L(以Al元素含量计算);然后在最佳的混凝条件下分别加入超声波的作用发现最佳的超声持续时间为30s;但是我们发现超声对硅的去除并不明显;超声作用混凝30s时,去除有机物的效率比传统混凝方法要高16.73%(以重铬酸钾指数为计)。得出结论:超声强化混凝对原水的浊度去除和有机物的去除都达到了很好的效果,而且比传统的混凝方法要好,但是在水中硅的去除方面和传统混凝相比TF并无优势。
隨著經濟和社會的髮展,水資源的微汙染問題日益嚴重,目前的水處理工藝必鬚攷慮到微汙染的問題。實驗首先尋找傳統混凝工藝的條件為pH=6.5~7.5,溫度T=17℃~18℃,最佳投加量6.384mg/L(以Al元素含量計算);然後在最佳的混凝條件下分彆加入超聲波的作用髮現最佳的超聲持續時間為30s;但是我們髮現超聲對硅的去除併不明顯;超聲作用混凝30s時,去除有機物的效率比傳統混凝方法要高16.73%(以重鉻痠鉀指數為計)。得齣結論:超聲彊化混凝對原水的濁度去除和有機物的去除都達到瞭很好的效果,而且比傳統的混凝方法要好,但是在水中硅的去除方麵和傳統混凝相比TF併無優勢。

With development of the economy and society, micro-contamination of water resources is a growing problem, the present water treatment plant must take into account micro-pollution. In this study, first of all loo- king for the traditional coagulation process conditions pH = 6.5 - 7.5, temperature T = 17 - 18 ℃, the best dosage of 6.384 mg/L( calculated with A1 content) ;then the best coagulation conditions were added the role of ultrasound to find the best duration of ultrasound 30 s; but we found ultrasonic removal of the silicon is not obvious;ultrasonic coagulation 30 s, the removal efficiency of organic matter than conventional coagulation method 16.73% higher ( in potassium dichromate). Concluded : Ultrasound enhanced coagulation of the raw water turbidity removal and the removal of organic matter has reached good results, and better than traditional methods of coagulation, but the removal of silicon in the water area and the traditional coagulation phase no ad- vantage compared
