5000-30000 mg/L；Coloration: 5000-20000 times.Wastewater biodegradability is poor, pollutes extremely serious, it is more difficult to handle.
Processing for this kind of waste water is usually first pre-processed using partition method, such as coagulating sedimentation or mixed condensed gas flotation process,
First dosing coagulant makes Organic Pollutants in Wastewater agglomerate to form sludge, then using the removal of the solid-liquid separating methods such as precipitating or air bearing
Suspension pollutant in waste water, water outlet carry out other chemistry or biological treatment again, realize rear discharge up to standard.What mud-water separation generated
Sludge carries out landfill disposal usually as solid waste by forming mud cake after mechanism filter-pressing or centrifugal dehydration, has both be easy to cause secondary dirt
Dye, and can not achieve resource utilization.

Mud forms bulk；Blocky sludge hot is squeezed and dries or spontaneously dries after being lower than 50% to moisture content；By sludge isolation air heating
To 450-650 DEG C of heat preservation 1-4h；Sludge is cooled to 50 DEG C or less and is broken into graininess, uniformly spraying mass concentration is 0.1-
It is uniformly mixed after 0.2% wetting agent solution, improves surface hydrophilicity, be prepared into floating type decolorising agent；Mud granule is pressed into 2-
10g/L waste water dosage is added in cationic dyeing waste water, and aeration stirring 10-180min can be such that decolorization rate of wastewater reaches
99.5% or more, it air bearing or filters to isolate mud granule and recycles；After recycling 450-650 DEG C of hot recycling of mud granule, circulation makes
With.
The utility model has the advantages that
A. black plastic printing waste water is treated by the present method, and percent of decolourization is up to 99.7% or more, CODCrRemoval rate reaches
90% or more, pollutant recovery rate realizes the resource utilization of solid waste up to 90% or more；
B. cationic dyeing waste water is added the floating type bleaching agent bleaching processing of preparation, and decolorization rate of wastewater reaches
99.5% or more and it is easy to mud-water separation.
