The beverage factory in the wastewater contains a large amount of carbohydrate, protein, fungi and other substances, if not treated, this kind of wastewater is discharged directly, can cause eutrophication of river in organic matter, and this kind of wastewater, a long time goes bad, stunk. The dangers of this kind of wastewater is very big still, therefore, beverage factory sewage must be processed, and can only be emissions. In the beverage factory sewage processing, commonly used water treatment agents are mainly: nonionic polyacrylamide.
First, nonionic polyacrylamide products
Nonionic polyacrylamide is water-soluble polymer or polyelectrolyte. Due to its molecular chain contains a certain number of polar groups, it can through the adsorption of solid particles suspended in water, make the bridge between particles or by charge neutralization condensed to form large floc particles. So, it can accelerate the particles in the slurry settlement, there is a very significant to speed up the solution to clarify, promote such as filtering effect. Is mainly used for all kinds of industrial waste water flocculation sedimentation, precipitation clarification process. Such as paper and pulp wastewater treatment, wastewater processing and metal smelting process of wastewater treatment, steel and stone processing plant waste water treatment, etc.
Second, beverage factory sewage treatment is more suitable for using nonionic polyacrylamide
In the sewage of beverage factory, through tests to understand that the wastewater contains a large number of pulp, protein, phenolic compounds, such as fungi, this kind of wastewater belongs to acidic water quality. Such water quality if the natural precipitation or direct discharge can cause water quality deterioration stunk, in the most suitable for this kind of wastewater treatment process to join nonionic polyacrylamide used as flocculant.
Nonionic polyacrylamide in acid wastewater beverage factory can remove turbidity of all kinds of mold compound, can rapidly form flocs and natural precipitation, water discharge, sedimentation tank at the bottom of the form, the available cationic polyacrylamide in sludge dewatering of sludge cake can be used for feed additives, chemical fertilizer additive, etc.
