Description

The efficient processing of a kind of waste paper making wastewater and comprehensive reutilization method and device thereof
Technical field
The invention belongs to technical field of sewage treatment equipment, further belong to the paper waste processing technology field, be specifically related to a kind of simple and convenient operation and maintenance, good, the reliable waste paper making wastewater of process stabilizing of discharging water quality is efficient processes and comprehensive recycling device.
Background technology
Papermaking technology is one of four inventions of China, progress along with technology, papermaking has become automatic production line production by the production of handicraft workshop formula, greatly improved production efficiency, papermaking must produce waste water, also can pull an oar, concentrate, copy the operation waste discharges such as paper even utilize regenerated papermaking, deinking, decolouring waste water are more arranged, contain the pollutents such as hemicellulose, xylogen, inorganic acid salt, fiber fines, mineral filler and printing ink, dyestuff in the waste paper making wastewater, hemicellulose, xylogen mainly form the COD(chemical oxygen demand (COD) of waste water), BOD 5(biochemical oxygen demand (BOD)), the main SS(suspended substance that forms such as fiber fines, mineral filler), main colourity and the COD of forming such as printing ink, dyestuff.Therefore, waste paper making wastewater discharging meeting unprocessed or that deal with discharging improperly causes COD, BOD to environment 5Reaching SS is main environmental pollution, but also can not directly utilize, and causes the serious waste of water resources.
BAF (BAF) is the sewage treatment technique that rises the nineties in last century, and is widely popular in developed countries such as American-European and Japan.This technique has removes SS, COD, BOD, nitrated, denitrogenation, dephosphorization, removal AOX(objectionable impurities) effect, be characterized in collecting bio-oxidation and hold back suspended solids and one, saved post precipitation pond (second pond), its volumetric loading, hydraulic load are large, hydraulic detention time is short, and required initial cost is few, and effluent quality is good, operation energy consumption is low, economic operating cost.
Anaerobic-aerobic (A/O) technique is that waste water is injected anaerobic pond, and the heterotrophic bacteria in the pond dissociates ammonia (NH with pollutent ammonifications (N on organic amount or the amino in the amino acid) such as the starch in the waste water, fiber, carbohydrate 3, NH 4+), make suspended contaminant and dissolved organic matter be hydrolyzed to organic acid, make larger molecular organics be classified as small organic molecule, insoluble organism is converted into dissolved organic matter, thereby improves the biodegradability of sewage; In Aerobic Pond under the condition of sufficient oxygen, from the nitrification of oxygen bacterium with NH 3-H(NH 4+) be oxidized to NO 3-, reflux denitrification at heterotrophic bacteria with NO by control 3-Be reduced to molecular nitrogen (N 2), realize the processing of sewage.
In the existing paper industry, generally take the single or compounding technology of precipitation, air supporting processing, biochemical treatment, BAF, A/O etc. to wastewater treatment.Single precipitation or air supporting are processed and are difficult to remove solubility COD and BOD 5, and single biochemical treatment is difficult to remove non-dissolubility COD, BOD 5And SS, and single technique pollutants removal rate is low, is difficult to reach the emission standard of national regulation, seldom uses; First heavy and chemical flocks and the biochemical treatment combined utilization that generally adopt, although can remove the organic pollutant of a large amount of polymer difficult degradations, but waste water water yield load performance is low, and discharge index is difficult to reach or only can reaches reluctantly existing GB emission standard after processing; Also have and adopt to add metal-salt as flocculation agent, although improved flocculation efficiency, do not increase desalination plant and then can cause the discharging metal-salt to exceed standard, otherwise can cause complex treatment process again, cost is high.Stack single or the reduction several method has been difficult to adapt to environmental requirement.The technical finesse waste water such as the membrane ultrafiltration of employing, reverse osmosis, electrodialysis, ion-exchange are also arranged at present, although these technology can be removed the most of pollutent in the waste water, have processing cost height, water quality and the weak shortcoming of water yield adaptive faculty, be difficult to apply.
Along with the attention of national environmental pollution and the reinforcement of water resources utilization management, the requirement meeting of discharge of wastewater is more and more tighter, and the cost that utilizes of water resources also can be higher.For this reason, develop a kind of simple process, running cost is low, and effluent quality is good, and the waste paper making wastewater of recoverable resource efficiently processes and comprehensive recycling device seems very meaningful, all is very favourable for improving water resources and paper making raw material resource utilization.
Summary of the invention
The first purpose of the present invention is to provide the efficient processing of a kind of waste paper making wastewater and comprehensive reutilization method; The second purpose is to provide that simple in structure, strong adaptability, the operation and maintenance of finishing described method are easy, good, the reliable and stable device of discharging water quality.
The first purpose of the present invention is achieved in that and comprises pre-treatment, hydrolysis reaction, biochemical treatment, separation of oxygenated, Air Exposure, post-processing step, specifically comprises:
A, pre-treatment: with fiber removal in the waste water, gravity flow enters the shallow air-floatation system, removes suspended substance and most of non-dissolubility COD, the BOD of the overwhelming majority 5And being partly dissolved property COD, BOD 5
B, hydrolysis reaction: the water outlet after the pre-treatment enters the active sludge that adds 1 ~ 5 times of weight ratio in the hydrolysis acidification pool and processes 8 ~ 24h;
C, biochemical treatment: the water outlet behind the hydrolysis reaction enters the A/O biochemistry pool is removed the overwhelming majority at the effect 24 ~ 72h of anoxic-aerobic microbiological solvability COD, BOD 5And the non-dissolubility COD of part, BOD 5
D, separation of oxygenated: the water outlet after biochemical treatment enters settling tank precipitation 8 ~ 24h, and supernatant liquor enters the Fenton reagent that adds 0.01 ~ 0.1 times of weight ratio in the oxidation reactor and carries out oxidizing reaction 8 ~ 12h;
