Description
Technical field
The present invention relates to a kind of infant industry waste water flocculant and preparation method thereof, belong to water treatment agent field.
Background technology
Flocculation is to apply one of most common key link in waste water treatment process, and it affects follow-up to a great extent
The operating condition of flow process, final outflow water quality and cost, thus become Technological research exploitation neck important in environmental project
Territory.Efficient flocculation technique system should be combined closely formed by excellent flocculant, reactor and automatic control three aspects of offeing medicine, its
Middle flocculant plays the role of a nucleus.Flocculation treatment technology it is crucial that select suitable flocculant.
The sorting technique of flocculant is a lot, by composition difference, typically can be classified as inorganic flocculating agent, organic flocculant,
Natural flocculating agent (such as biological flocculant), if after dissociating according to the height of flocculating agent molecule amount, the feature of functional group and functional group
Charged character, can be further divided into macromolecule, low molecule, cationic, anionic and nonionic flocculation
Agent etc..Wherein, inorganic flocculating agent can be divided into the big class of aluminium salt system and iron salt system two by slaine: aluminium salt with aluminum sulfate, aluminum chloride is
Main, iron salt is based on iron sulfate, iron chloride.Inorganic polymer flocculant is that the sixties in 20th century is at traditional iron salt, aluminium salt base
The class novel flocculant grown up on plinth, is main product and the main direction of studying of inorganic flocculating agent, mainly includes gathering
Close aluminum sulfate, aluminium polychlorid, bodied ferric sulfate, poly-ferric chloride etc..Inorganic polymer flocculant has than original tradition medicament
Preferably flocculating effect and phase dutiable value is relatively low, in Japan, Russia, West Europe, the Chinese production all having considerable scale with answer
With, the production of polymeric type medicament accounts for the 30～60% of flocculant total amount.
High-concentration industrial-water had both been different from sanitary sewage, and also different from general trade effluent, often containing multiple has
The pollutant such as hardly degraded organic substance, heavy metal ion and the ammonia nitrogen that poison is harmful, complicated component, the at present poly-aluminum of routine, Polyferric Sulfate etc.
Flocculant is undesirable due to the flocculation single treatment effect to these high-concentration waste waters of component, particularly pollutes dissolubility in water
The place to go effect of thing is bad.So for high-concentration waste water, also lack at present a kind of wide spectrum, efficiently, good stability, single-minded
The flocculant that property is strong, flocculating property is excellent, the ratio of performance to price is moderate.
