| 摘 要： | 在常规处理条件下,对西南地区突发性非多砂高浊度原水进行了加药条件优化试验.结果表明,采用单级絮凝、分级沉淀工艺,先投加PAC,60～120 s后投加PAM,对高浊度原水有良好的去除效果.原水浊度为15 000 NTU时,投加200 mg/L PAC、0.4～0.5 mg/L PAM,静沉30 min后.出水浊度为1.7...

| Abstract: | An optimization test of dosing condition for emergent non-sediment high turbidity raw water under conventional process was conducted in southwest of China.The result showed that satisfied removal efficiency for high turbidity raw water could be obtained by first dosing PAC,then dosing PAM with a time interval from 60 s to 120 s in the single-stage flocculation and grading sedimentation.When the raw water turbidity was 15 000 NTU,the effluent turbidity could be 1.73 to 2.48 NTU after dosing of 200 mg/L PAC,a... |
