Technical field
The utility model relates to a kind of papermaking midcourse wastewater treatment technology, particularly relates to ultraviolet ray/hydrogen peroxide and the biochemical combined reactor of handling papermaking midcourse wastewater.
Background technology
Paper industry water consumption and wastewater discharge are big, and pollutant load is very high, and water is seriously polluted.Middle-stage wastewater derives from after the pulp-making waste-water, comprise pulp washing rare black liquor, washing and screening waste water, bleaching effluent, wash net, wash the unnecessary plain boiled water of blanket waste water, paper machine room etc.Therefore middle-stage wastewater is that a source is complicated, the system of complicated component, and the processing of middle-stage wastewater is very crucial.Papermaking midcourse wastewater there are two Basic Ways both at home and abroad, the one, from waste water, separate organism, colourity is reduced, such as flocculation, absorption and membrane sepn etc.; The 2nd, destroy organism, chroma in waste water is reduced, such as chemical oxidization method, photochemical method, biological process and electrochemical process etc.
Hydrogen peroxide H
2O
2The molecular reaction oxidisability is strong, can directly react with the toxic organic compound material, makes the toxicant degraded, and improves the biodegradability of waste water.In addition, H
2O
2Under the ultraviolet (UV) activation, be converted into more strong oxidizing property particle such as OH, enhanced oxidation efficient.Yet, ultraviolet ray/hydrogen peroxide (UV/H
2O) to wastewater oxidation, though effect is good, processing cost is higher, if with routine biochemistry and UV/H
2The O oxide compound to bring into play the strong point of a technology, has reduced processing cost, and can make the papermaking midcourse wastewater reuse, to the conserve water resource, subdues effluent charge, effectively administers paper waste and has important and practical meanings.
