摘　　要：通过烧杯试验及生产性应用试验研究发现,给水厂机加池中投加PAM可以显著提高池内污泥沉降速度,有效解决冬季低温低浊条件下混凝效果不佳问题,对出厂水浊度有很好的控制效果;同时还能够提高排泥效率,有效降低排泥能耗。研究结果显示:在0.5 mg/L的试验投加量范围内未见对水厂其他工艺环节产生不利影响;在水厂实际应用中投加量控制在0.25 mg/L以内效果稳定。Through laboratory and production tests, it is proved that PAM can increase the sludge settling rate in the mechanical accelerating clarifier of waterworks, which can solve the coagulation problem of low temperature and low turbidity in winter, and has good control of turbidity.At the same time, it can improve the sludge discharge efficiency and effectively reduce the sludge discharge energy consumption;There was no adverse effect on other processes in the water plant within the range of 0.5 mg/L test dosage. The practical application of dosing control within 0.25 mg/L in waterworks has a good effect.
