Flotation pond add polyaluminium chloride after the yellow floc normal? Float pond pollination after the addition of polyaluminum yellow floc there? With the growing domestic and foreign industries, and now in the industrial water treatment The above mentioned problems often appear above. In fact, this is related to the quality of the water itself which type of agent, in particular, a variety of types of polyacrylamide, these different types of polyacrylamide for the type of wastewater are also different, and sometimes not that the degree of ion High treatment effect is better, which also depends on what type of water quality to adapt. Therefore, the filter water purification plant in this proposal, before the actual treatment of water quality can be coordinated with the supplier to help select the type, in order to cause secondary pollution and processing costs increase. A factory water treatment process will break the milk after the first solution to the sedimentation tank, into the polyacrylamide, and then from the sedimentation tank to the flotation tank and then discharged. However, in the sedimentation tank only polyacrylamide, in the flotation tank only polyaluminum chloride. Seen from the surface of the sedimentation tank effluent is not clear, after adding polyaluminum in the flotation pond more yellow flocculent flotation of the water there are always floc. Is it because of the dosing problem? That dosing order needs to be changed? In fact, based on these problems can be analyzed that: the main reason for the water is not clarified due to poor flocculation effect. Proposed after demulsification dosing some coagulant plus polyacrylamide, which can improve the precipitation effect. The general reasons for the water does not clarify the clarification of the water In addition to the above said flocculation effect is poor and referred to the dosing sequence, the precipitation effect is also good or bad with the dosage, polyacrylamide model, wastewater and pharmaceutical The degree of mixing is the mixing effect, precipitation time, etc. are also related. Therefore, before the actual treatment is best to do a little try to determine the amount of polyaluminum chloride and polyacrylamide dosing, if the conditions are also selected polyacrylamide model, which for the treatment efficiency can play a big help.
