Description
Technical field
The present invention relates to technical field of sewage, particularly relate to a kind of textile sewage flocculant.
Background technology
In textile printing and dyeing sewage, mainly contain various slurries additional in dirt, grease, salt and the process on textile fabric, dyestuff, surfactant, auxiliary agent, soda acid etc. Textile printing and dyeing wastewater has the features such as the water yield is large, organic pollution content is high, colourity is dark, change of water quality is large, belongs to unmanageable industrial wastewater.
Along with the development of the fine fabric of chemistry, the raising that the rise of Silk and finishing process in printing and dye-ing require, make the hardly degraded organic substances such as PVA slurry, artificial silk alkaline hydrolysis thing, new dye, auxiliary agent enter in a large number textile printing and dyeing wastewater, traditional waste water treatment process is formed to serious challenge. In prior art to textile sewage process be mainly single molysite, aluminium salt as chemical floc, dosage is large, decolorizing effect is poor, not only treatment effect is bad, and equipment is had to stronger corrosivity.
Summary of the invention
Object of the present invention is exactly to provide a kind of textile sewage flocculant for the defect of above-mentioned existence. This flocculant is for the treatment of textile printing and dyeing wastewater, by textile printing and dyeing wastewater first after grid filtration, enter sedimentation basin, flocculant is dropped in the textile printing and dyeing wastewater in sedimentation basin and processed, this flocculant comprises polyaluminium sulfate, sodium aluminate, activated silicic acid, diatomite, borax, composition wherein under mutual coordinative role for the treatment of textile printing and dyeing wastewater, cohesion effect is fast, good decolorizing effect, dosage is little, be applicable to the textile waste that change of water quality is large, acidproof, heat resistance good, be adapted to water temperature and change waste water greatly.
A kind of textile sewage flocculant technical scheme of the present invention is to comprise polyaluminium sulfate [Al2（OH）m（SO4）3-]n, sodium aluminate Na2Al2O4, activated silicic acid, diatomite, borax.
Polyaluminium sulfate is by a certain amount of Al2（SO4）3With Ca(OH)2Solution reacts at a certain temperature and slaking makes.
Activated silicic acid is sodium metasilicate Na2O·nSiO2, wherein, n=2.5-2.8.
Specifically comprise following composition by weight: polyaluminium sulfate 20-30 part, sodium aluminate 5-15 part, activated silicic acid 3-5 part, diatomite 5-8 part, borax 5-15 part.
Preferably, comprise following composition by weight: 25 parts of polyaluminium sulfates, 10 parts of sodium aluminates, 4 parts of activated silicic acids, 6 parts, diatomite, 10 parts of boraxs.
This flocculant also contains sodium acetate.
Sodium acetate accounts for the 2-8% of the percentage by weight of flocculant.
Described a kind of textile sewage flocculant, every 1L sewage drops into the flocculant of 200-800mg.
Beneficial effect of the present invention is: this flocculant comprises polyaluminium sulfate, sodium aluminate, activated silicic acid, diatomite, borax, composition wherein under mutual coordinative role for the treatment of textile printing and dyeing wastewater, cohesion effect is fast, good decolorizing effect, dosage is little, be applicable to the textile waste that change of water quality is large, acidproof, heat resistance good, be adapted to water temperature and change waste water greatly.
