Dyeing wastewater with a large displacement of waste water , complex organic components , high concentrations of pollutants , refractory material , color and high toxicity and other characteristics , relying solely on the biochemical method for processing low removal rate of CODCr and chroma difficult to meet emissions standards. The electroflocculation technology is a water treatment technology development prospects , its treatment of dyeing wastewater with high COD removal efficiency and decolorization rate, the processing time is short , small footprint, strong impact resistance and easy operation and management . This paper systematically introduces the basic principles of electro-flocculation , application, development prospects and problems, blankets dyeing wastewater , electric blankets dyeing wastewater flocculation process parameters were the single factor experiment and orthogonal experiment UV - visible spectroscopy experiments , the experimental results show that : the electric flocculation method blanket dyeing wastewater treatment , its combination of superior level DC power the electroflocculation time 30min, the power supply voltage to 90V . This combination of test conditions , CODCr and chroma removal rates were 72.8% and 88.9% energy consumption for 0.005kW.h / g , the ideal treatment effect , low energy consumption . This paper presents a combination of biochemical treatment electroflocculation process route , which is a new , effective and feasible , discharge standards of technical route , can not only solve the problem of environmental pollution , you can also create considerable economic benefits , but also to promote China dyeing and environmentally friendly technologies , in order to create wealth, has a very important theoretical and practical significance .
