Description
Technical field
The present invention relates to a kind of electric flocculation apparatus, particularly a kind of electric flocculation apparatus for organic waste water and electroplating wastewater processing, specifically the wastewater treatment refining plant of electric flocculation sewage treatment plant and high-voltage pulse power source composition.
Background technology
The difficulties of sewage disposal technology is the processing to the organic waste water of high-concentration hardly-degradable and electroplating wastewater.This type of waste water is mainly the waste water producing in the production processes such as dyestuff, agricultural chemicals, biological medicine, chemical industry and plating.The common feature of this class waste water is exactly organism or the heavy metal that contains difficult degradation, and that Pollutants in Wastewater forms is complicated, kind is many, concentration is high, toxicity is large, salinity is higher, and in electroplating wastewater, contained heavy metal is high in addition, and pH value is lower again.If not adding improvement, these materials are not just discharged in environment, will certainly serious pollution of ecological environment and threat HUMAN HEALTH.Conventional technology is before entering biochemical treatment, first to carry out pre-treatment; and pre-treatment is common or adopt strong oxidation technology to destroy organic molecular structure, be beneficial to follow-up biochemical action; or adopt chemical precipitation technology to make heavy metal form inner complex precipitation or make some colloidalmaterials take off steady postprecipitation, to alleviate the load of follow-up biochemical action.At present in conventional strong oxidation technology, electrochemical process is exactly wherein a kind of.
Electrochemical process wastewater treatment electric flocculation apparatus used normally adopts high-voltage pulse power source as power supply, and in addition, this equipment also comprises having the electrolyzer of water-in and water outlet and be located at the electrode plate groups in electrolyzer.This equipment carries out a series of rapid polarization such as electrolysis, flocculation, air supporting and reacts by the waste water in electrolyzer, thereby waste water is purified.Yet current high-voltage pulse electric flocculation equipment has the following disadvantages:
Although an equipment has adopted high-voltage pulse power source, by the timing conversion of negative electrode and positive electrode, reduce the passivation phenomenon on metal polar plate surface, in actual motion, the passivation phenomenon on metal polar plate surface still exists.The passivation phenomenon on metal polar plate surface can cause operating resistance constantly to increase, and electrolytic process cannot smooth and easyly be analysed positive plate metal ion in water, thereby has greatly weakened redox reaction, causes the decrease in efficiency of disposing of sewage.In order to improve the efficiency of electric flocculation apparatus, be usually by increasing current density or improving voltage and solve problem, but increase current density or improve the direct result that voltage has brought again energy consumption increase, processing cost rising and pole plate passivation speed to accelerate.
Two, metal polar plate constantly consumes, and need to change in time.What conventionally adopt due to pole plate is the steel plate of monoblock, therefore must adopt electric block or manually chain block change, operate cumbersomely, and also need electrode wires to re-start welding when replacing pole plate.
Three, water inlet must keep acidity (pH < 4) to work, and when pending sewage pH > 4, acid adding is adjusted to pH < 4 in addition, just can complete reaction.Acid adding causes the increase of working cost.
Four, when processing the sewage of specific conductivity > 30000mS/m, because sewage conductive capability is excessively strong, during operation, electric current is excessive, the conventional basic Non voltage output of high-voltage pulse electric flocculation equipment, so cisco unity malfunction.
