Abstract
The process of treating effluent from making paper with waste paper belongs to the field of industrial effluent treating technology, and aims at lowering the harmful matter content in the effluent from making paper with waste paper to reach the exhaust standard. The process includes the first passing the effluent through grating to filter out fiber and suspended matter, the subsequent settling in a sloping plate settling tank to eliminate granular impurity, flocculating in an air floating tank with flocculant and fishing out the resultant suspended matter, anaerobic reaction in an anaerobic settling tank, treating with introduced air and active sludge in an aeration tank and eliminating suspended matter and colloidal matter, clarifying in a settling tank, and treating in artificial wetland to eliminate nitrogen and phosphate and obtain clear water. The process can reduce SS, BOD5 and CODcr of the effluent obviously and make the effluent reach draining standard.
Description
Technical field
The invention belongs to the industrial sewage treatment technology field, particularly a kind of paper waste treatment process.
Background technology
Regenerated papermaking is a main raw material with useless paperboard, disregard message paper, useless book paper etc., products such as the white board of production plurality of specifications, boxboard, fluting board.Mainly contain pollutents such as hemicellulose, xylogen, inorganic acid salt, fiber fines, mineral filler and printing ink, dyestuff in the waste paper making wastewater.Xylogen, hemicellulose mainly form the COD and the BOD of waste water
5The main SS that forms such as fiber fines, mineral filler; Main colourity and the COD of forming such as printing ink, dyestuff.It is all higher that these pollutent concentrated expressions go out SS, the COD index of waste water.
The waste water treatment technology technologies that adopt to regenerated papermaking are more at present:
(1), with pitch grid or nylon wire to papermaking after effusive waste water filter, reclaim the fiber in the waste water;
(2), again waste water is flowed into inclined-plate clarifying basin, the granular impurity in the precipitation removal waste water;
(3), the waste water in the inclined-plate clarifying basin is flowed into air flotation pool, adding flocculation agent, the fine-fibered in the cohesion water;
(4), the reacted suspended substance of waste water in the air flotation pool and flocculation agent salvaged to the pond, removes, then the waste water in the pond is flowed into the precipitation anaerobic pond, carry out biochemical anaerobic reaction, remove objectionable constituent;
After the aforesaid method processing, can remove SS, remove most of non-solubility COD and being partly dissolved property COD and BOD simultaneously
5
Show that yet research and analyse generally, each Pollutant levels is in the treated waste water: SS approximately is 62mg/l, BOD
5Approximately be 180mg/l, CODcr approximately is 460mg/l, as seen, though be greatly improved by the waste water water quality after the aforesaid method processing, but still do not reach national environmental protection emission standards and requirement.
Summary of the invention
Objectionable impurities exceeds standard in the present regeneration paper mill wastewater processing in order to solve, and can not reach the problem of emission standard, the invention provides a kind of method for processing paper-making waste water of regenerative paper, and its technical scheme is as follows:
The paper waste treatment process, this method comprises the steps:
(1), filtered and recycled: with pitch be 0.15mm～0.25mm grid or 60 orders～70 order nylon wires to papermaking after effusive waste water filter, the waste water after the filtration flows into the fiber recovery pond, reclaims fiber and other suspended substance in the waste water;
(2), precipitation purifies: the waste water in the fiber recovery pond is flowed into inclined-plate clarifying basin, and precipitation is removed the granular impurity in the waste water;
(3), air supporting removes fine: the waste water in the inclined-plate clarifying basin is flowed into air flotation pool, add flocculation agent in air flotation pool, with flocculation agent and waste water uniform mixing, condense the fine-fibered in the water;
(4), anaerobic treatment: waste water in the air flotation pool and the reacted suspended substance of flocculation agent are salvaged to the pond, then the waste water in the pond is flowed into the precipitation anaerobic pond;
(5), aerobic is handled: the waste water that will precipitate in the anaerobic pond flows into the aeration tank, in the aeration tank, add and contain microbic activity mud, carry out aeration from the bottom bubbling air of aeration tank, the blast inlet mean number of bottom, aeration tank is to be no less than 2 in 1 square metre;
(6), secondary sedimentation: the waste water in the aeration tank is flowed into secondary sedimentation basins, and the secondary sedimentation basins bottom is a gravel bed system;
(7), wetland purification: the primary purifying water in the secondary sedimentation basins is flowed into the artificial swamp pond, the bottom in artificial swamp pond and be the antiseep wall all around, kind is implanted with plant in the pond;
(8), water purification reclaims: artificial swamp is not held the effusive inflow clean water basin of purifying waste water, recycle.
After the aforesaid method processing, SS, BOD in the waste water
5, CODcr obviously reduces, clearance is: SS is 98.95%, BOD
5Be 95.11%, CODcr is 93.51%, emission concentration all meets " paper industry pollution discharge standard " requirement.
