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1.73～2.48NTU。
An optimization test of dosing condition for water under conventional process was conducted in southwest emergent non-sediment high turbidity raw 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, and 0.4 to 0.5 mg/L PAM with retention time of 30 min.
