摘要:
针对传统无机铝盐絮凝剂在处理低温低浊水时残余铝过高的问题,采用中试装置,应用复合型生物絮凝剂(CBF)处理北方地区冬季低温低浊水源水,考察了在不同混凝条件下处理后水中残余铝浓度的变化。结果表明:复合型生物絮凝剂对水中残余铝有很好的效果,在与聚合氯化铝铁复配进行强化混凝的试验当中,混凝效果提高36.1%,总投药量降低了15%,并且消除了聚合氯化铝铁(PAFC)导致的残余铝升高的现象,出水残余铝浓度仅为0.016 mg/L。综合考虑处理效果与投药量,建议复合型微生物絮凝剂与聚合氯化铝铁的最佳复配比为2 mg/L∶15 mg/L。
Abstract:
In view of higher concentration of residual Al in the clarified water in the treatment of low turbidity source water by conventional inorganic flocculent,compound bioflocculant(CBF) is used to treat the low turbidity raw water taken from the reservoir in North China in winter.Both jar test and pilot scale flocculation treatment processes are investigated for removing the residual Al from low turbidity water.The test results of the coagulation show that CBF has an effective performance in residual Al removal.Residual Al removal is enhanced by the combination of CBF and polymerized aluminium ferrum chloride(PAFC),CBF restrains the escalating trend of residual Al caused by the Al from PAFC,the concentration of residual Al is 0.016 mg/L.Based on an overall analysis of residual Al removal efficiency and the dosage of flocculant,the optimal dosage for treatment of low turbidity water is CBF=2 mg/L and PAFC=15 mg/L.
