摘要
Abstract
The circulating waste water has the characteristics of high hardness and alkalinity.It is easy to cause reverse osmosis membrane fouling and performance lowering.Thus,the coagulation-softening technology was applied to conduct water treatment,and the results were compared with that by other softening methods.The results show that:the conventional lime coagulation and so-dium carbonate coagulation were less effective;mixing sodium hydroxide and sodium carbonate was more effective.When the dosage of each softener was 250 mg/L,the calcium,magnesium ions and organ phosphorus of treated water were 0.85 mmol/L,2.44 mmol/L and 0.73 mg/L,respec-tively,which satisfied the inlet water requirements.关键词
