Description
Technical field
The present invention relates to technical field of waste water processing, more particularly to a kind of composite oxidant and preparation method thereof.
Background technology
With deepening continuously for process of industrialization, global environmental pollution increasingly destroys global biosphere institute over several hundred million years
The ecological balance of formation, and constitute a threat to the living environment of mankind itself.It is dirty to China's water environment according to State Environmental Protection Administration
The statistics and investigation, rivers, lake and the coastal waters basin in China for contaminating present situation are generally subject to different degrees of pollution, are generally in
The trend now aggravated, the principal element for polluting exacerbation are industrial wastewater and sanitary sewage.
Textile and dyeing industry discharges substantial amounts of waste water and waste residue in process of production to produce pollution to environment, wherein with print
Pollution of the waste water discharged during dye industry production to environment is the most serious.According to incompletely statistics, national dyeing waste water is daily
Discharge capacity is (3-4) × 106m3, the 35% of national industrial wastewater total release is accounted for, and increase year by year with 1% speed.Discharge
Entrainment in waste water containing fibrous raw material in itself, and process slurry, finish, dyestuff and chemical assistant for using etc.,
There is biochemical oxygen demand (BOD) height, colourity height, pH value height, difficult for biological degradation, diverse " a three high hardly possiblies one become ".It is residual in waste water
The dye component deposited, even if concentration is very low, is discharged into the reduction that water body will also result in gas solubility in water body light transmittance and water body,
Various biological growths in water can be influenced, so as to destroy the food chain of water body purity and aquatile, most cause water body to be given birth at last
The destruction of state system.Therefore, the governing problem of printing and dyeing industrial waste water, it has also become Now Domestic external environment engineering circles are badly in need of what is solved
A great problem.
Dyeing produces a large amount of dyeing waste waters every year, is extremely difficult to one of the industrial wastewater of processing.Conventional water process medicine
Agent has been unable to meet process demand, must research and develop the water treatment agent of new high-efficiency for this.
