摘要
以济南市水质净化一厂初沉池进水为试验水样,在设定的反应条件下,以浊度、COD、TP、TN、NH3-N等为测定指标,做了大量的烧杯搅拌试验,综合分析了聚合氯化铁铝(PFAC)的处理效果。试验结果显示其最佳投药量为25mg/L左右,去除率浊度在90%以上、COD70%~90%、TP70%~95%左右、TN、NH3-N分别在30%和15%左右。
Based on the test conditions of coagulation-flocculation process, a series of jar test was conducted to analyse the treatment efficiency of polymeric ferric aluminium chloride (PFAC) with the inlet effluents collected from a primary sedimentation tank of a water purification plant in Jinan as wastewater samples. Results indicated that the optimal dosage was around 25 mg/L, turbidity of removal efficiency over 90%, COD ranged in 70~90%, TP 70~95%, TN and NH3-N 30% and 15% respectively.
