Description
Technical field
The present invention relates to process for treating industrial waste water and treatment unit, especially relate to coking and treatment method of printing and dying wastewater and processing isolated plant.
Background technology
Along with the continuous development of industry, Industrial Wastewater Treatment is measured with difficulty and is also constantly increased, and waste water such as particularly coking, petrochemical industry and printing and dyeing are current more reluctant several waste water.At present, process for treating industrial waste water mainly adopts biological treatment and burning method: one, bioremediation is to adopt pre-treatment earlier, to remove grease and the solid carbon in the trade effluent, then carrying out the deep aeration materialization again handles, to remove the ammonia in the trade effluent, nitrogen, phenol, sulphur, objectionable impurities such as sulfide and prussic acid, the treating processes required time of this biochemical processing method is more than 60 hours, suspended substance colloid to turbidity and colourity, the removal processing efficiency of COD has only about 70%, it is huge that engineering is dropped on the bioremediation basis, treatment system working cost height, system handles is affected by environment bigger, especially handles coking and dyeing waste water, treatment effect instability in the time at low temperature; Its two, though burning method can be effectively to Industrial Wastewater Treatment, burning method is that main fuel sprays into precombustion in the stove with combustion gas, fuel oil, spray into waste water then, make waste water oxidation at high temperature produce nitrogen and water, thereby burning method processing costs cost is quite high, practical extending application value is low.In addition, adopt activated sludge process to trade effluent, especially coking and dyeing waste water are handled in addition, though this abolishment water treatment method treatment effect increases, effluent characteristics makes moderate progress, but handle pulvis and all become mud, be difficult to handle the pulvis resurrection and separate repeated use once more, processing costs cost height.
In above-mentioned prior art, the problem that exists when trade effluent, particularly coking and treatment of dyeing wastewater the invention provides that a kind of wastewater treatment running cost is low, processing efficiency is high, the method for wastewater treatment of energy-conserving and environment-protective and treatment unit.
The object of the present invention is achieved like this:
Method of wastewater treatment of the present invention comprises waste water conventional processing and deep treatment method, and described conventional processing comprises the a-d method steps, and described advanced treatment comprises the e-g method steps:
