Abstract
The invention relates to the technical field of wastewater treatment, in particular to a composite flocculating agent for treating printing and dyeing wastewater. The composite flocculating agent is prepared from, by weight, 1-3 parts of active carbon, 10-15 parts of coal briquette residues, 10-15 parts of alum powder, 15-25 parts of polyaluminum chloride and 4-8 parts of calcium chloride. The flocculating agent is reasonable in component compatibility, and is good in flocculating effect and high in chromaticity and suspended matter removing rate after all the components are in intercoordination; the composite flocculating agent is low in cost, free of corrosion to equipment and good in economic benefit, and raw materials are easy to obtain.
Description
Technical field
The present invention relates to technical field of sewage, be specifically related to a kind of dyeing and printing sewage and process with multiple
Mould assembly flocculant.
Background technology
The sewage of textile printing and dyeing discharge mainly contains the fiber dirt on textile fabric, dyeing and finishing work
The oils and fats of coating, various slurries additional in salt, and the course of processing, dyestuff, table in skill
Face activating agent, auxiliary agent, soda acid etc..Textile printing and dyeing wastewater has that the water yield is big, organic pollution contains
The features such as amount is high, colourity is deep, change of water quality is big, belong to intractable industrial wastewater.
Along with carrying that the development of the fine fabric of chemistry, the rise of Silk and finishing process in printing and dye-ing require
Height, makes the hardly degraded organic substances such as PVA slurry, artificial silk alkaline hydrolysis thing, new dye, auxiliary agent big
Amount enters textile printing and dyeing wastewater, and traditional waste water treatment process is constituted serious challenge.Existing skill
Art processes mainly the most single iron salt, aluminium salt to textile sewage as chemical floc, medication
Amount is big, and decolorizing effect is poor, and not only treatment effect is bad, and has stronger corrosivity to equipment.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of flocculating effect good, colourity is with outstanding
The dyeing and printing sewage process composite flocculant that float clearance is high.
For realizing object above, the present invention is achieved by the following technical programs:
A kind of dyeing and printing sewage process composite flocculant, is made up of the raw material of following weight portion:
Activated carbon 1-3 part, coal briquette slag 10-15 part, alum powder 10-15 part, aluminium polychlorid 15-25
Part, calcium chloride 4-8 part.
Preferably, described dyeing and printing sewage process composite flocculant, by following weight portion
Raw material forms: activated carbon 1-2 part, coal briquette slag 12-13 part, alum powder 12-14 part, polymerization
Aluminum chloride 18-22 part, calcium chloride 5-6 part.
Preferably, described dyeing and printing sewage process composite flocculant, by following weight portion
Raw material forms: activated carbon 1 part, coal briquette slag 13 parts, alum powder 12 parts, aluminium polychlorid
22 parts, 5 parts of calcium chloride.
Preferably, described aluminium polychlorid chemical formula is Al2(OH)nCl6-nm。
Preferably, the n=2.5-3.8, m=3-8 in described Al2 (OH) nCl6-nm.
Preferably, described dyeing and printing sewage process composite flocculant, every 1L sewage puts into
The flocculant of 0.8-1.5g.
The invention have the benefit that
1. the flocculant component compatibility that the present invention provides is reasonable, and activated carbon is to trace organic in sewage
Material has good adsorption；Coal briquette slag space is big, can get off with float coprecipitation；
Alum powder has the effect purifying water；Aluminium polychlorid hydrolysis rate is fast, high adsorption capacity,
The close precipitation of matter is fast, and delivery turbidity is low；Calcium chloride can regulate the PH of sewage；Each component is mutually coordinated
After, flocculating effect is good, and colourity and removal efficiency are high.
2. the flocculant that the present invention provides is with low cost, and raw material is easy to get, and not etching apparatus, economical
Profitable.
Detailed description of the invention
