Abstract
The invention discloses a high-efficient waste water flocculant and a preparation method thereof and belongs to the field of water treatment agents. The high-efficient waste water flocculant is prepared from the following raw materials in parts by weight: 1 to 9 parts of sodium humate, 1 to 5 parts of sepiolite, 5 to 10 parts of aluminium polychlorid, 1 to 5 parts of poly-silicon aluminum sulfate, 3 to 9 parts of magnesium sulfate, 5 to 10 parts of polyoxyethylene, 2 to 8 parts of dimethylamine, 3 to 9 parts of alginic acid, 3 to 9 parts of barium carbonate, 5 to 20 parts of coal ash and 70 to 100 parts of water. The high-efficient waste water flocculant disclosed by the invention has the advantages that flocculent precipitation time is short, the effect is good and the cost is low; the active emulsifying ability of water molecules is improved, and hazardous substances and heavy metal of water are degraded; especially, both high-concentration and high-turbidity waste water and non-biochemicalized waste water can be effectively treated, and the treated water can be recycled.
Description
Technical field
The present invention relates to a kind of efficient waste water flocculant and preparation method thereof, belong to water conditioner field.
Background technology
Flocculation applies one of the most general key link in waste water treatment process, and it affects the operation condition of follow-up flow process, final outflow water quality and cost to a great extent, thus becomes Technological research development field important in environmental engineering.Efficient flocculation technique system should be combined closely and formed by the flocculation agent of excellence, reactor and automatic control three aspects of offeing medicine, and wherein flocculation agent plays the role of a nucleus.The key of flocculation treatment technology selects suitable flocculation agent.
The sorting technique of flocculation agent is a lot, different by composition, generally can be divided into inorganic flocculating agent, organic floculant, natural flocculating agent (as biological flocculant), if according to charged character after the height of flocculating agent molecule amount, the feature of functional group and functional group's dissociation, polymer, low molecule, cationic, anionic and flocculant in non-ion type etc. can be further divided into.Wherein, inorganic flocculating agent can be divided into the large class of aluminium salt system and molysite system two by metal-salt: aluminium salt is based on Tai-Ace S 150, aluminum chloride, and molysite is based on ferric sulfate, iron(ic) chloride.Inorganic polymer flocculant is the class novel flocculant grown up on traditional molysite, aluminium salt basis the sixties in 20th century, be main product and the main direction of studying of inorganic flocculating agent, mainly comprise polyaluminium sulfate, polymerize aluminum chloride, bodied ferric sulfate, poly-ferric chloride etc.Inorganic polymer flocculant has better flocculating effect than original traditional medicament and phase dutiable value is lower, and in Japan, Russia, West Europe, Chinese production and the application all having considerable scale, the production of polymeric type medicament accounts for 30 ~ 60% of flocculation agent total amount.
High-concentration industrial-water was both different from sanitary sewage, also general industrial sewage is different from, often containing pollutents such as multiple poisonous and hazardous hardly degraded organic substance, heavy metal ion and ammonia nitrogens, complicated component, the flocculation agent such as poly-aluminium, Polyferric Sulfate of current routine due to the single treatment effect to these high-concentration waste waters of flocculation component undesirable, particularly bad to the place to go effect of dissolubility pollutant in water.So for high-concentration waste water, also lack a kind of wide spectrum, the flocculation agent that efficient, good stability, specificity are strong, flocculating property is excellent, the ratio of performance to price is moderate at present.
