- 摘要:
- 文章研究了低温低浊水混凝剂及助凝剂的优化选择，考察了浊度、CODMn、氨氮等水质特征，分析了低温低浊水的处理效果。结果表明，混凝剂和助凝剂投加量增大，上清液中浊度、COD去除率不断提高。在PAFC用量为12 mg/L，活化硅酸用量为0.12 mg/L条件下，浊度、COD去除率分别达到最大值98.3％和87％，剩余浊度和剩余CODMn分别为0.21 NTU、0.64 mg/L。而PAC＋PAM表现出更好的除氨氮效果，剩余氨氮为0.07 mg/L。
- Abstract:
- In this paper the treatment of the water with low temperature and low turbidity by selected co-agulants and coagulant aids was studied,along with such water qualities as turbidity,CODMn ,ammonia nitrogen investigated and the low temperature and low water treatment effect analyzed.The results show that as the dos-age of coagulants and coagulant aids increases,supernatant turbidity,CODMn removal rate increase.In the a-mount of PAFC 12 mg /L and activated silicic acid 0.12 mg /L,the removal rate of turbidity,CODMn reaches a maximum of 98.3%and 87%.Residual turbidity and residual COD were 0.21 NTU,0.64 mg /L.The PAC+PAM showed a better effect in addition to ammonia.Residual ammonia was 0.07 mg /L.
