Its content of organics is more, and coloration is high, pollution it is extremely serious (coloration: 30,000 times or more, CODCr: 100,000-50 ten thousand mg/L), it is difficult to locate
Reason.It generallys use the physico-chemical process such as Coagulation Method to be pre-processed, i.e., the dosing coagulant into waste liquid, pollutant is made to agglomerate shape
It at sludge, is separated by solid-liquid separation using the mechanical dehydrations method such as filters pressing, centrifugal dehydration, water outlet is carried out again at other chemistry or biology
It manages to qualified discharge.Since pollutant concentration is high in waste liquid, the sludge solid content of formation is up to 5-10%, and mud cake is aqueous after dehydration
Rate is still up to 80% or more.Landfill disposal is carried out usually as solid waste by the mud cake formed after mechanism filter-pressing or centrifugal dehydration,
It is easy to cause secondary pollution.
Summary of the invention
It is useless using a kind of preparation printing and dyeing of black water ink jet printing pulp thickening object that the purpose of the present invention is to provide a kind of
The method of water decolorant.
A kind of decolorizing printing and dyeing waste water agent, mainly by mass fraction be 80-90 black water ink jet printing pulp thickening object,
The calcium miberal powder composition of 5-10 parts of sepiolite and 5-10 part, preparation method are as follows: by black water ink jet printing pulp thickening object
It is modulated into the pulpous state sludge of certain solid content, and appropriate alkaline matter is added and is neutralized to neutrality；Quality percentage is added into sludge
Calcium miberal powder (in terms of over dry mud dry weight) than sepiolite and 5%-15% for 5%-15% stirs evenly；Sludge is added while stirring
Heat makes sludge form bulk, takes off Chinese effluent to 50-90 DEG C of dehydration；Blocky sludge hot is squeezed and is done after being lower than 50% to moisture content
It is dry；Sludge isolation air is heated to 350-700 DEG C of heat preservation 1-5h；Sludge is broken into graininess after being down to certain temperature, preparation
At decolorizing printing and dyeing waste water agent.
The invention has the following advantages that
A. the decolorising agent of high concentration black water ink jet printing pulp thickening object preparation is used for decolorizing printing and dyeing waste water, decoloration
Rate nearly 100%, and decolorization rate is fast；
B. decolorizing printing and dyeing waste water agent is prepared with high concentration black water ink jet printing pulp thickening object, realizes the money of solid waste
Sourceization utilizes, and has prevented sludge secondary pollution problem；
C. decolorising agent uses rear 450-750 DEG C of hot recycling, can be recycled, and effect is constant.
