Abstract
The invention relates to a process device for waste water generated in tobacco sheet production. The process device comprises a machinery coarse screen collecting tank, a rotary grillage machine, a floatation tank, a primary decalcification reaction tank, a secondary decalcification reaction tank, a coagulating basin, a primary settling tank, a regulating tank, a hydrolysis acidification pool, a UASB (upflow anaerobic sludge blanket) anaerobic pool, an electrolysis machine a, an anoxic pool, an aerobiotic pool, a medium settling tank, an electrolysis machine b, an MBR (membrane biological reactor) system, an electrolysis disinfection tank, a sludge tank, a sludge dewatering tank, an accident pool, a gas collecting device and a methane storing tank. The process device is based on the combination of a chemical decalcification technology, a biochemical technology, an electrochemical technology and an MBR technology, thus having low cost and high efficiency, and the discharged waste water reaches the standard.
Description
The present invention relates to a kind for the treatment of unit of tobacco sheet factory effluent, particularly relate to a kind ofly based on the tobacco sheet factory effluent of chemical decalcification technology, Measurement for Biochemistry, electrochemical techniques and MBR technology and the treatment unit of tobacco factory effluent, belong to the water pollution control field of environmental engineering.
Background technology
Tobacco leaf is when producing, and raw material can not be utilized completely, and tobacco to the production process of making cigarette, can produce the particle that accounts for former cigarette material total amount 1/3 greatly from preliminary working, and these tobacco particles can't directly be made cigarette product as raw material again.In order to reduce the comprehensive utilization that waste material produces, realizes particle, the tobacco sheet technology is arisen at the historic moment.Tobacco sheet, having another name called reconstituted tobacco (Reconstituted Tobacco), is to utilize tobacco materials such as offal, offal, tobacco cut to make sheet or thread reconstituted product for raw material, as cigarette filler, reduce the tar content in the cigarette, reduce the Health hazard that smoking brings to human body.The use of tobacco sheet has the tobacco quality of raising, reduces the cigarette cost, saves plurality of advantages such as raw materials consumption, resource reutilization.Roll-in method, thick slurry method and paper process are the main production methods of current tobacco sheet.Compare with thick slurry method thin slice with roll-in method, the paper process thin slice has remarkable advantages: reduce production of cigarettes cost, constant product quality, filling value and becomes a silk rate height, anti-machining property good, improved the combustionvelocity of cigarette and reduced releasing content of coke tar, product plasticity-is high and more easily process, and is effective technology of present production " health type " cigarette.Have roll-in method and the incomparable advantage of thick slurry method just because of the papermaking thin slice, therefore all obtained extensive popularization at home and abroad.
The general character of the existing paper waste of waste water that produces in the tobacco sheets by paper making method production process is as containing a large amount of fibers, have again simultaneously that tobacco wastewater colourity height, biodegradability are relatively poor, contain to characteristics such as the disadvantageous nicotine of microorganism growth and the high 150～500mg/L of calcium-magnesium content main contamination index such as following table in the waste water:
Waste strength fluctuation simultaneously is bigger, and CODcr is from 1500～25000mg/L, and SS is from 1000～15000mg/L, and nicotine and tar suppress microorganism growth, and the calcium-magnesium content height causes reactor fouling normally not move, and belongs to the difficult organic waste water of high density.
Chinese patent CN1683261A discloses a kind for the treatment of process of tobacco sheets by paper making method factory effluent, i.e. the treatment process of the tobacco sheet factory effluent of coagulation air-float+aerobic oxidation+mechanical filter.
Chinese patent CN102276093A discloses a kind for the treatment of process of tobacco sheets by paper making method factory effluent, and this technology may further comprise the steps: by the grid coarse filtration, gravity flow enters wastewater equalization pond with factory effluent; By lift pump the waste water in the wastewater equalization pond is promoted to and adds Ca-diatom soil series compound flocculating agent reaction 5-10min in the coagulator, add bodied ferric sulfate then, the polyacrylamide separating agent enters the reaction of static reaction pond, the reaction times is 50-60min; Be to pump in the ultrasonic micro-electrolysis reactor after the slant acidity with the pH regulator of the organic waste water of lower concentration, react jointly by ultrasonic wave and little electrolysis that the chemical oxygen demand material is cleared up fast, and the reaction times is 30-60min; Again with waste water process charcoal absorption and quartz sand filtration; The mud that equalizing tank and static reaction pond workshop section are produced is handled the back through overlapping screwed sludge dewatering equipment and is used as solid fuel.
Disclose the tobacco sheets by paper making method factory effluent among the Chinese patent CN10133045A and to three-stage filtration, be back to slurrying workshop section through one more respectively, reuse water adopts the method that regularly is thrown into sewage works, but factory effluent loops back for the production of influencing the thin slice quality greatly.
Chinese patent CN1683261A discloses the tobacco sheets by paper making method factory effluent and has removed wherein suspended solid through coagulating treatment, air supporting method earlier, sends into the most COD material is removed in the aeration tank by aerobic microbiological method then.
Above method all has certain effect to the processing of tobacco sheet factory effluent, technical process is long, facility investment is big, floor space is big but exist, defectives such as working cost height, more seriously owing to contain a large amount of calcium in the waste water, directly cause a large amount of foulings of biochemical treatment system and film separating system, system can't normally move, and the waste discharge after existing wastewater processing technology is handled all can not reach emission standard.
Summary of the invention
The objective of the invention is in the existing tobacco production wastewater treatment method existing establish technical process long, be equipped with that investment is big, floor space is big, working cost is high, biochemical treatment system and film processing system be because fouling can not normally move, defectives such as the waste discharge after the processing is not up to standard, providing a kind of combines with the MBR technology based on chemical decalcification technology, Measurement for Biochemistry, electrochemical techniques, cost is lower, usefulness is higher, makes it the treatment unit of the tobacco factory effluent of qualified discharge.
A kind for the treatment of unit of tobacco sheet factory effluent comprises mechanical coarse rack water collecting basin, rotation grid maker, air flotation pool, one-level decalcification reaction tank, secondary decalcification reaction tank, coagulation basin, preliminary sedimentation tank, equalizing tank, hydrolysis acidification pool, UASB anaerobic pond, electrolysis machine a, anoxic pond, Aerobic Pond, medium sediment pool, electrolysis machine b, MBR system, electrosterilization pond, sludge sump, sludge dehydration device, accident pool, gas collector and biogas gas holder;
