Description
Summary:Using hydrochloric acid solution and rare earth concentrate mixed heating method, which is prepared a new polymer flocculant polymerization of rare earth coagulants (PRE), studied the amount of coagulant, pH value, slowly stir intensity, slowly stir time, sediment time on polymerization of rare earth coagulants coagulation effect. And will fuse rare earth coagulants (PRE) with common coagulants IC simplifies PFC and PAC conducted comparative experiments. By dealing with the yellow studies showed that the polymerization of rare earth coagulants optimum flocculation conditions for pH value for 5 ~ 9, Slowly stir intensity 70r/min, Slowly stir time 10 min, Settling time 10 min, Polymerization of rare earth of coagulant coagulation effect is better than that of IC simplifies PFC and PAC, Has formed body structure is close-grained, settlement flocculant good performance, less, to generate sludge volume turbidity removal efficiency high characteristic.
