Description
Technical field
The present invention relates to technical field of sewage, particularly a kind of Environment-friendlysewage sewage treatment agent.
Background technology
According to statistics, not only scale is large for the quantity discharged of China's stain disease, and speedup is swift and violent.Calendar year 2001, the quantity discharged of China's stain disease rose to 685.4 hundred million tons from 432.9 hundred million tons, and annual growth reaches 4.86% by 2012.The trade effluent in city and sanitary sewage are the main handling objects of sewage work.Sewerage system has connect water natural circulation and has circulated with society, and sewage work balances the water quantity reduction of water cycle.The municipal effluent of the whole nation more than 80% is just directly discharged into neighbouring water body without any effective collection and treatment, and China's industrial wastewater pollution is serious, and causing has more than 80% to receive in more than 500 trunk river in the whole nation to pollute in various degree.
Dyeing is water consumption rich and influential family, and wastewater discharge and the total amount of pollutant occupy the second of national industrial sector and the 4th respectively, is that China's emphasis pollutes one of industry.Dyeing waste water always large with quantity discharged, intractability is high and become the Focal point and difficult point of waste water treatment technical study.And dyeing waste water is especially the most difficult with chemical fiber waste water, its waste component is complicated, normal containing strong acid, highly basic, Mierocrystalline cellulose, hemicellulose, alcohols, pectin etc., and various toxic substance, wastewater biodegradability is poor, BOD/COD is generally less than 0.25, and containing toxic substances such as aldehydes, cyanogen class, benzene classes, easily produces toxic action to microorganism.
Urban sewage treatment system is one of the important infrastructure in city, also prevents water pollution, and improves the important means of urban water environmental quality.Healthy as city and develop basis, water treatment seems important all the more.Because China is developing country, economic level is also very backward, for the water pollution control of China in economic support less than European and American developed countries.Therefore we can not imitate developed country completely for the construction of sewage work, suit measures to local conditions.Meanwhile, sewage work needs to drop into substantial contribution, running cost accounts for 1% of China GDP, huge investment and working cost have increased the weight of the economical load of China undoubtedly, still also very backward compared with the sewage disposal technology state of the art external with the same period that China adopts, have that efficiency is low, energy consumption is high all the time, etc. shortcoming.Can the processing efficiency problem that solve sewage work have become the key factor determining sewage work's on-road efficiency quality.The New Technologies that exploitation is applicable to wastewater treatment in China factory present situation is just the inevitable course.
The sewage-treating agent of current water treatment field, mainly comprises gac, diatomite, activated silica gel, atlapulgite, macromolecule resin etc., its function is comparatively single, and such as, only to a certain specific pollutants factor, it acts on rear and needs frequent regeneration macromolecule resin; Single-activity charcoal highlights the absorption of micropore, have ignored the effect in other holes; Diatomite pore size is also too single.
Summary of the invention
The invention provides a kind of Environment-friendlysewage sewage treatment agent, nontoxicity, affect operator little, be applicable to all types of industries sewage, treatment effect is good, wherein especially with the most outstanding to chemical fiber waste water effect, and the problem of non-secondary pollution after process.
A kind of Environment-friendlysewage sewage treatment agent, by weight, comprises following component:
Gac 30 ~ 80 parts;
Bamboo charcoal 30 ~ 80 parts;
10 ~ 20 parts, diatomite;
Attapulgite 10 ~ 15 parts;
Montmorillonite 5 ~ 12 parts;
Poly-aluminum ferric chloride sulfate 25 ~ 45 parts;
Described gac uses that superoxol is modified to be obtained.
There is in sewage-treating agent of the present invention the component for dissimilar pollutent, component used comprises natural micropore (gac), the material of mesopore (diatomite, attapulgite, montmorillonite) and macropore (bamboo charcoal) structure.Carbon material (gac and bamboo charcoal) and silicate Porous materials (diatomite, attapulgite, montmorillonite) combine, mutually work in coordination with between each material, especially bamboo charcoal and the synergy of modified gac respectively and between poly-aluminum ferric chloride sulfate, poly-aluminum ferric chloride sulfate compression double electric layer, forms flco, improves alumen ustum structure in sewage on the one hand; On the other hand, because bamboo charcoal and modified activated carbon have huge specific surface area and stronger surface adsorption function, can de-steady colloid in rapid adsorption water, and improve the content of material surface oxygen-containing functional group through the gac of modification, strengthen the adsorptive power to polar material solvable in water.Cooperatively interact between three, can rapidly and pollutent form the large and closely knit flco of granularity, have good stability.
In order to reduce over the consumption of hydrogen peroxide solution, ensure modified effect simultaneously, preferably, described gac is flood 2 ~ 10h post-drying in the superoxol of 10% ~ 30% to obtain in mass concentration, and the mass ratio of described gac and superoxol is 5 ~ 15.
