Large supply of sewage treatment agent

The new Lotte sewage treatment diatomite diatomite surface with a negative charge, so the colloidal contaminants positively charged, it can be achieved in electricity and leaving the colloidal stability. But most comprehensive urban sewage or waste water colloidal particles are negatively charged, so as with conventional diatomaceous earth as sewage treatment agent, can only play the role of the electric double layer compression, but can not make the destabilization of colloidal particles, treatment ineffective. So the diatomite modified in various ways, making it negatively charged colloidal particles can also be destabilization. Such as aluminum, iron and other positively charged ions on the surface modification, or add other flocculant made of modified diatomite water treatment agent. For composite made of other flocculants modified diatomite treatment agent, the diatomaceous earth on the one hand can be used as a skeleton floc, improve alum structure that helps coagulate the role of the floc formed by compacting And there is a good settlement, thereby improving the general chemical flocculant producing alum loose, easily sinking condition; on the other hand, because of its large specific surface area and surface adsorption, etc., can easily be destabilized colloid adsorbed onto Celite, and the adhesion ability of diatomaceous earth particles attract each other pollutants are also among the big, so-modified diatomite for sewage treatment, can quickly form a larger particle size and density of the floc, and floc stability, even after being shattered when the floc, flocculation can also occur again - which is the other aluminum, iron and other common sewage flocculants unmatched. Diatomite huge surface area, strong adsorption and surface electrical resistance, making it in the sewage treatment process, not only to remove pollutants and particulate colloidal, but also effectively remove the color and to the presence of dissolved phosphorus (resulting in one of the main pollutants eutrophication) and metal ions. Especially for urban sewage contains a higher proportion of industrial waste, which may have a greater chroma and high concentrations of metal ions, but modified diatomite processing system, because of its negatively charged surface, can effectively removing a portion of the adsorption of positively charged metal ions. Diatomite process equipment for sewage treatment effect of its treatment has a great influence. Water clarifiers are usually only used for water treatment, and for general urban sewage treatment, because the sewage contains large amounts of organic matter and microorganisms can occur and produce gas in anaerobic sludge suspended layer, which will destroy the suspension layer stability. But recent studies have found that the addition of the necessary facilities or methods clarifier so suspended sludge layer maintains a hypoxic state, can effectively inhibit the production of gas, to ensure the formation of a stable pool suspended sludge layer. This process with respect to the vertical flow, advection or radial flow sedimentation tank, it can greatly reduce the dosage and improve the system damping force. Mainly because the sludge suspended layer sieve into account the role of floc particles can be trapped; suspension layer does not reach its saturation diatomite, dissolved contaminants can be further adsorption and flocculation flocculation of colloids and not the water, the medicine Great potential to maximize, thus saving the amount of the agent. When inadequate dosage or water quality, the water has an impact, the reactor suspension layer can help adsorption, trapped pollutants in water, play a cushioning effect, thereby improving the stability of the system. Sewage diatomite I plant for sewage treatment Celite diatomite as Changbai Mountain high-quality raw materials, through the drying, selection, crushing, ingredients, and other high-temperature calcination series of automated processing technology made it light porous, relatively incompressible, large surface area, adsorption performance, low cost, high efficiency filtration, the filtrate was clear and transparent, is currently the best filter material. By a certain percentage into the sewage treatment flocculation process, by stirring diatoms diatomaceous earth can be sufficiently dispersed into monomers and suspended in water, it can quickly adsorption and flocculation substance and form the core of the body, however, took the lead by virtue of its own weight and precipitate . So Diatomite is a high quality water coagulant, play a larger vanadium flowers, accelerate sedimentation, reduce sludge volume and improve sludge dewatering performance role. Diatomite water coagulant is a light, porous, relatively incompressible, the specific surface area to fight, fine solids strong adsorption properties of powder. By a certain percentage into the sewage treatment flocculation process, by stirring diatoms diatomaceous earth can be sufficiently dispersed into monomer and suspended in wastewater, it can quickly adsorption and flocculation substance and form the core of the body, but by virtue of their weight and lead in precipitation. So Diatomite is a premium sewage treatment agent, play a larger vanadium flowers, accelerate sedimentation, reduce sludge volume and improve sludge dewatering performance role.
