Abstract
The invention discloses the processing method of a kind of pulping papermaking sewerage.Method includes following step: pulping papermaking sewerage by strainer filtering impurity, is obtained the sewage of decontamination by (1)；(2), after the sewage regulation PH of decontamination being 56, it is placed in reactor, adds activated sludge, phosphorus-solubilizing bacteria, nitrogen-fixing bacteria, carbamide and mineral-type microcosmic salt, process the water after being purified with sequencing batch active sludge；(3) water after purifying is by discharging after resin filter film.The processing method of the present invention adds after phosphorus-solubilizing bacteria, nitrogen-fixing bacteria and mineral-type microcosmic salt being combined with certain proportion, secretes phosphatase by phosphorus-solubilizing bacteria, promotes that in water, the lytic agent of invalid phosphorus utilizes, and reduces adding of mineral-type phosphorus source；Increase microorganism by nitrogen-fixing bacteria nitrogen source is absorbed；Final step is by discharging after resin filter film, and sewage is again filtered, reduces cost, improves the absorbance of nitrogen phosphorus, decreases total nitrogen and the content of total phosphorus in discharge water.
Description
Technical field:
The present invention relates to the processing method of a kind of pulping papermaking sewerage, belong to pulping wastewater treatment technical field.
Background technology:
Pulp and paper industry wastewater discharge is big, and in waste water, platform has substantial amounts of cellulose, lignin and various chemical drugs, and oxygen consumption is big, is one of primary pollution source polluting environment.The U.S. is classified as one of six big public hazards, and Japan is classified as one of five big public hazards.In China, pulp and paper industry wastewater discharge accounts for the 1/6 of industrial wastewater, COD and SS all accounts for 1/4, and paper waste pollutes the most serious. and the Chinese people people's livelihood is included and causes serious impact with ecological environment, therefore, it is necessary to paper-making effluent is effectively processed.
Paper-making effluent concentration is high, and COD, BOD content is big, and its processing method is different compared with commonly industrial wastewater, and at present, the processing method of paper waste mainly has Physical, chemical method, bioanalysis and physical-chemical process.Wherein being most widely used of bioanalysis, it has also become one of main method of paper waste two stage treatment.Pulping papermaking sewerage biological treatment stage at present, the few phosphorus waste water of nitrogen stress is while supplementary N, P nutrition, final outflow water but has strict discharge standard to N, P index, not only to guarantee the most effectively to supplement N, P nutrition at leading portion, ensure the growth and breeding of microorganism, and back segment water outlet N, P to be kept can stably reaching standards.Maintain balance therebetween.
Summary of the invention:
The present invention seeks to, be used for making up the deficiencies in the prior art, and the processing method of a kind of pulping papermaking sewerage is provided.
To achieve these goals, technical scheme is as follows:
A kind of processing method of pulping papermaking sewerage, including following step:
(1) by pulping papermaking sewerage by strainer filtering impurity, the sewage of decontamination is obtained；
(2), after the sewage regulation PH of decontamination being 5-6, it is placed in reactor, adds activated sludge, phosphorus-solubilizing bacteria, nitrogen-fixing bacteria, carbamide and mineral-type microcosmic salt, process the water after being purified with sequencing batch active sludge；
(3) water after the purification that will obtain in step (2) is by discharging after resin filter film.
The processing method of described a kind of pulping papermaking sewerage, in terms of the sewage parts by weight 1000 parts of decontamination, the activated sludge of addition, phosphorus-solubilizing bacteria, nitrogen-fixing bacteria, carbamide and mineral-type microcosmic salt are respectively as follows: 100-120 part, 0.8-1.2 part, 0.2-0.6 part, 11-18 part and 5-10 part in terms of parts by weight.
The processing method of described a kind of pulping papermaking sewerage, described mineral-type microcosmic salt is ammonium dihydrogen phosphate, sodium dihydrogen phosphate or disodium hydrogen phosphate.
The processing method of described a kind of pulping papermaking sewerage, processes in pond in step (2) and is also added into cellulose-decomposing bacterium.
The processing method of described a kind of pulping papermaking sewerage, the addition of described cellulose-decomposing bacterium is the 0.1-0.3 ‰ of decontamination sewage weight.
The processing method of described a kind of pulping papermaking sewerage, the aperture of described resin filter film is 0.4-0.6 μm.
Beneficial effects of the present invention is as follows:
The processing method of the present invention adds after phosphorus-solubilizing bacteria, nitrogen-fixing bacteria and mineral-type microcosmic salt being combined with certain proportion, secretes phosphatase by phosphorus-solubilizing bacteria, promotes that in water, the lytic agent of invalid phosphorus utilizes, and reduces adding of mineral-type phosphorus source；Increase microorganism by nitrogen-fixing bacteria nitrogen source is absorbed；Final step is by discharging after resin filter film, and sewage is again filtered, reduces cost, improves the absorbance of nitrogen phosphorus, decreases total nitrogen and the content of total phosphorus in discharge water；It is finally reached the effect of pollution reduction, and cost-saved 0.04 yuan of water per ton.
Paper waste some contain lignin and cellulose etc. some be difficult to the material degraded, add cellulose-decomposing bacterium and can strengthen fiber and the decomposition efficiency of lignin in waste water.The aperture of filter membrane is that 0.4-0.6 μm can retain small molecular weight impurity.
