摘要
采用中试试验对比研究了混凝-气浮与混凝-沉淀工艺对鹊山水库典型低温低浊水的处理效果。试验采用聚合氯化铝铁混凝剂,对气浮工艺PAFC投加量采用5 mg/L(以Al3+计),较沉淀工艺投加量低17%。连续试验表明,气浮工艺处理低温低浊水优于沉淀工艺,对浊度、颗粒数、CODMn、UV254、DOC的去除率分别高7.7%、12.8%、3.9%、5.1%和8.5%。
The pilot treatment effects between coagulation- dissolved air flocculation process（ DAF） and coagulation- sedimentation process for the low temperature and turbidity water of Queshan reservoir are compared. The polyaluminium chloride iron（ PAFC） coagulant is used. The dosing quantity of PAFC of DAF process is 5 mg / L,17% lower than that in coagulation- sedimentation process. The continuous test shows that for the low temperature and turbidity reservoir water the DAF process is superior to coagulation- sedimentation process. The removal rates of turbidity,particle counts,CODMn,UV254 and DOC by DAF are 7. 7%,12. 8%,3. 9%,5. 1% and 8. 5% respectively higher than those by sedimentation process.
