Description

Dynamic little electrolytic waste water treatment equipment and water treatment method thereof
Technical field
What the present invention relates to is a kind of device and treatment process thereof of water-treatment technology field, specifically is a kind of dynamic little electrolytic waste water treatment equipment and water treatment method thereof.
Background technology
For many years, China is obtaining huge achievement aspect city domestic sewage, the bio-degradable Industrial Wastewater Treatment, for China environmental protection has been made important contribution.In recent years along with the fast development of chemistry, pharmacy, petrochemical industry, few but the concentration height of the water yield, difficult degradation, the organic waste water that salinity is high are more and more, this class waste water has become new public hazards, only uses single biochemical treatment, can't reach the emission request of country at all.Processing for this class high-concentration hardly-degradable waste water must be adopted preconditioning technique, by destroying the molecular structure of hardly degraded organic substance, reduce COD and colourity significantly, improve the biodegradability of waste water, for biochemical treatment creates conditions, thereby finally realize the standard wastewater discharge target.
In numerous preconditioning techniques, the little electrolysis of iron charcoal is considered to cheap, green, effective preconditioning technique, this technology is a raw material with waste iron filing and gac, by the many trickle galvanic cell that forms between iron filings and the carbon granule and iron filings and powdered carbon forms around it big galvanic cell and organic wastewater with difficult degradation thereby little electrolytic redox reaction taking place, and carries out pre-treatment.In little electrolytic while, aeration can improve the oxidizing potential of micro-electrolysis reaction, can improve the efficient of micro-electrolysis reaction effectively.
The little electrolysis treatment technology of existing iron charcoal mainly adopts the fixed bed processing mode---and iron filings and carbon granule mixed and alternate are piled up the fixed bed that forms; treatment effect is very unstable; initial stage can show very high purification efficiency; but prolongation along with the time; lump mutually between the intravital iron filings of bed, stop up reaction bed, seriously hindered the further reaction of iron anode; cause treatment effect to descend rapidly, even cause the inefficacy of treatment unit.Recently dynamic little electrolytic waste water treatment equipment, the particularly cylinder electrolytic waste water treatment equipment that declines owing to can solve hardening of a body, has caused people's interest.But existing dynamic little electrolytic waste water treatment equipment all exists obvious defects at water distribution, gas distribution, drainage exhaust mode and the aspects such as reinforced and discharging of device, has influenced the processing efficiency and the operation of device.
Through the retrieval of prior art is found, Shen Binzai " Chinese water supply and drainage " 2002,18 (6) 18-19 have introduced a kind of " novel cylinder reactor internal electrolysis flocculation bed " handles the method for waste water; China Patent No. 03206783.6 discloses " Continuous Flow is strengthened little electrolytic waste water treatment equipment " and has been applied to wastewater treatment; China Patent No. 200520072494.0 discloses " horizontal little catalytic and oxidative electrolysis technology reactor rolls " and has been applied to wastewater treatment.Drum-type micro-electrolytic water treatment process based on these device foundation, the problems such as the obstruction of hardening of iron charcoal fixed bed have been solved well, but water distribution, gas distribution, drainage exhaust mode and aspects such as reinforced and discharging at device all exist obvious defects, thereby affect the processing efficiency and the operation of device.For example Shen Bin is at " Chinese water supply and drainage " 2002, " novel cylinder internal electrolysis flocculation bed " device that 18 (6) 18-19 introduce just is not provided with aerating apparatus, thereby the little electrolytic oxidation efficiency of iron charcoal is lower, and this device is not resolved the charging and the problems such as discharging and maintenance of iron charcoal in the operational process yet in addition.China Patent No. 03206783.6 open " Continuous Flow is strengthened little electrolytic waste water treatment equipment ", although in reaction unit, designed aeration, but still the oxygen deprivation problem of the little electrolysis zone of unresolved good iron charcoal.The disclosure is divided into three districts with reactor, inhalant region, little electrolysis zone and exhalant region, and inlet pipe is by forming heavy-oxygen-enriched water to the inhalant region aeration, and heavy-oxygen-enriched water enters the micro-electrolysis reaction district again; Because the micro-electrolysis reaction district is reduced state, the heavy-oxygen-enriched water of inhalant region enters the far-end that has become oxygen deprivation water, particularly little electrolysis zone behind little electrolysis zone soon, almost can't obtain heavy-oxygen-enriched water, thereby influence the processing efficiency of device; This device does not have the solution for problems such as the iron charcoal charging that exists in the engineering operation, deslagginves yet in addition.China Patent No. 200520072494.0 open " horizontal little catalytic and oxidative electrolysis technology reactor rolls " in device with the water-in design in reactor above, water outlet also places the top in the reactor, the as easy as rolling off a log water that causes into is without effective mixing, directly the short circuit problem of being discharged by water outlet; The opening for feed of iron charcoal and slag-drip opening design simultaneously not only causes the generation of the iron charcoal skewness problem on the engineering operation easily in the both sides of reactor, and has brought difficulty to the charging on the engineering and deslagging and operation.
