Description
Technical field
The utility model belongs to pulping wastewater treatment technical field, more particularly to a kind of paper waste system for anaerobic treatment.
Background technology
Paper industry is that water consumption is big, heavy-polluted industry, the organic matter of paper waste discharge（That is COD）Account for China's industry
Wastewater through organic matter total amount about 25%, seriously pollutes environment, and therefore, paper making wastewater zero discharge is the life that a water saving and pollution treatment are laid equal stress on
Practical technique is produced, there is preferable economic benefit, it may have obvious social benefit and environmental benefit, and paper industry are realized
The necessary choice of sustainable development.At present, pulping wastewater treatment is one big industrial problem of China, and oxygen content is low in paper waste,
Condition is poor, and cultivation aerobic bacteria is higher organic pollution decomposition difficulty, and it is more to produce sludge.
In summary, the problem of prior art is present be：Oxygen content is low in paper waste, cultivates aerobic bacteria organic contamination
Thing decomposition difficulty is higher, and it is more to produce sludge.
Utility model content
The problem of existing for prior art, the utility model provide a kind of paper waste system for anaerobic treatment.
The utility model is achieved in that the paper waste system for anaerobic treatment is provided with anaerobic reactor, described to detest
The upper end of oxygen reactor is set with suction fan, the end connection biogas pipe of the suction fan；
The bottom of the anaerobic reactor, which is inlayed, is provided with sludge absorption net, is symmetrically inlayed on the outer wall of the anaerobic reactor
Scarfweld is connected to drainpipe and water inlet pipe.
Further, the water inlet pipe is arranged on the upper end of sludge absorption net, and the drainpipe is arranged on sludge absorption net
Lower end；Flowmeter is separately installed with the water inlet pipe and drainpipe.
Further, inlayed inside the anaerobic reactor of the suction fan lower end and spray equipment is installed, the spray equipment
On be provided with some spray apertures.
Further, the end of the biogas pipe is communicated with aspiration pump, and the output end of aspiration pump is provided with dehydrating unit.
Further, the mounting hole to match with sludge absorption net, the installation are provided with the anaerobic reactor outer wall
The buckle for being provided with and matching with sludge absorption net is inlayed on the inwall in hole.
The advantages of the utility model and good effect are：The paper waste system for anaerobic treatment floor space is small, charging ratio
Height, the impurity in waste water is adsorbed by sludge absorption net, caused biogas is reclaimed by suction fan；It will can handle
Cross a certain degree of paper waste further to be purified, the reacted solid-state of anaerobism mushroom, liquid, gaseous state product are separated
Open, without oxygen, sludge yield is few, generates the biogas of recoverable.
Brief description of the drawings
Fig. 1 is the structural representation for the paper waste system for anaerobic treatment that the utility model embodiment provides；
In figure：1st, biogas pipe；2nd, suction fan；3rd, anaerobic reactor；4th, drainpipe；5th, sludge absorption net；6th, water inlet pipe；7、

The mounting hole of matching, the buckle for being provided with and matching with sludge absorption net 5 is inlayed on the inwall of the mounting hole.
A certain degree of paper waste will be handled to be discharged into anaerobic reactor 3 by water inlet pipe 6, by anaerobic reactor
Anaerobic bacteria in 3 base sludge adsorption nets 5 is decomposed paper waste；After the conveniently replaced long-time use of mounting hole
Sludge absorption net 5, convenient replacing and cleaning to sludge absorption net 5；It is fixed, is added by buckle after the completion of replacing
Firmness, avoid dropping during use.Paper waste after decomposition is transported to next reaction unit, anaerobism by drainpipe 4
Bacterium decomposition generation sludge is few, and new caused anaerobic sludge is deposited in the bottom of anaerobic reactor 3, can be excluded, caused biogas
Drawn using suction fan 2, carry out impurity exclusion to producing gas by the spray apertures on spray equipment 7, pass through biogas pipe 1
It is transported to biogas storage equipment.Treated a certain degree of paper waste is further purified, after anaerobism mushroom is reacted
Solid-state, liquid, gaseous state product separate, without oxygen, sludge yield is few, generates the biogas of recoverable；Pass through
Aspiration pump improves the extraction speed of biogas, and the moisture in biogas can be effectively removed by dehydrating unit.
Described above is only to preferred embodiment of the present utility model, not the utility model is made any formal
Limitation, it is every according to the technical essence of the utility model to any simple modification made for any of the above embodiments, equivalent variations with
