Description
【Technical field】
The utility model is related to a kind of papermaking sewage treatment system, it is adaptable to Sewage field.
【Background technology】
With continuing to develop for China's economic society, environmental protection consciousness is also improved constantly, and every environmental protection index is also continuous
Improve, for paper industry, the discharge of waste water is inevitable, and the key index of paper industry discharge of wastewater is exactly COD
Value, therefore COD value is up to standard great for environment protection significance.In actual production process, with the change of production task, workshop
Production capacity also corresponding adjustment therewith, this COD value of waste water for causing workshop to be discharged is in a larger scope, permanent in disposal ability
In the case of fixed, COD value of waste water changes greatly the actual motion for being unfavorable for sewage disposal system, has not both reached treatment effeciency or same
When extend processing time.
For this problem, the utility model arises at the historic moment.
【Utility model content】
The utility model purpose is to overcome the deficiencies in the prior art there is provided a kind of simple and practical, papermaking of convenient and efficient
Sewage disposal system.
The utility model is achieved through the following technical solutions：
A kind of papermaking sewage treatment system, it is characterised in that：Including pre-reaction device, the anaerobic reaction dress being sequentially connected
Put, aerobic reaction device, chemical reaction equipment, settler, filtering adsorpting device, wherein, the pre-reaction device with precipitation
Device is inversely connected.
Paper sewage disposal system as described above, it is characterised in that the pre-reaction device is pre-acidified pond.
Paper sewage disposal system as described above, it is characterised in that the anaerobic reaction device is IC reactors, UASB is anti-
Answer device or EGSB reactors.
Paper sewage disposal system as described above, it is characterised in that the aerobic reaction device is aeration tank.
Paper sewage disposal system as described above, it is characterised in that the chemical reaction equipment is chemical reactor.
Paper sewage disposal system as described above, it is characterised in that the settler is sedimentation basin.
Paper sewage disposal system as described above, it is characterised in that the filtering adsorpting device includes sand filter and activated carbon
Absorber, the sand filter is connected to before active carbon adsorber.
Compared with prior art, the utility model has the following advantages：
1. papermaking sewage treatment system described in the utility model is by pre-acidified, anaerobism, the series reaction such as aerobic, most
Paper waste is caused to reach emission request by filtering absorption eventually, and the COD value for change is then carried out using processing water backflow
Regulation, can effectively ensure that the treatment effeciency of this papermaking sewage treatment system, reaches discharge standard；
2. papermaking sewage treatment system described in the utility model uses high efficiency anaerobic reactor such as IC reactors, UASB
Reactor or EGSB reactors effectively ensure the treatment effeciency of anaerobic stages, reduce the COD value of waste water；
3. papermaking sewage treatment system described in the utility model is because of its simple and practical, convenient and efficient, therefore is applicable to big
The papermaking enterprise of majority adjustment production capacity.
【Brief description of the drawings】
Fig. 1 is the flow chart of papermaking sewage treatment system described in the utility model；
Fig. 2 is the flow chart of one of the utility model embodiment.
【Embodiment】
Embodiment of the present utility model is elaborated below in conjunction with the accompanying drawings：
As shown in figure 1, a kind of papermaking sewage treatment system that the utility model is related to, including the pre-reaction dress being sequentially connected
1, anaerobic reaction device 2, aerobic reaction device 3, chemical reaction equipment 4, settler 5, filtering adsorpting device 6 are put, wherein, institute
Pre-reaction device 1 is stated inversely to connect with settler 5.
The pre-reaction device 1 is pre-acidified pond, and paper waste regulates pH value in advance herein, while for change
COD value, with the processing water of settler mix so as to adjust the COD value of waste water herein, to reach or close to anaerobism
Reaction unit enters water quality standard, it is ensured that treatment effeciency.
The anaerobic reaction device 2 is IC reactors, UASB reactors or EGSB reactors, and this kind of reactor can be effective
Ensure the treatment effeciency of anaerobic stages, reduce the COD value of waste water.
The aerobic reaction device 3 is aeration tank, and it can be fully aerated so that aerobic reaction is completeer using air blower
Entirely.
The chemical reaction equipment 4 is chemical reactor, herein the added sodium hypochlorite of waste water, and aluminum sulfate etc. to give up
Water is aoxidized, the reaction such as precipitation.
The settler 5 is sedimentation basin, and the further deposit buildup of material precipitated herein, the sedimentation basin is additionally provided with row
Dirty pipeline is discharged to deposit.
The filtering adsorpting device 6 includes sand filter 61 and active carbon adsorber 62, and the sand filter 61 is connected to activity
Before charcoal absorber 62, waste water is filtered through fine sand herein and charcoal absorption causes deposit to be further blocked, living
Property charcoal can then adsorb the discharged wastewater met the national standard after other harmful substances, final process.
Backflow regulating effect such as following table of the papermaking sewage treatment system described in the utility model in pre-acidified pond：(unit
mg/L)
| Operation stage | COD level | Do not flow back | Anaerobic effluent flows back | Precipitate effluent recycling |
| Workshop raw water | 6000~7500 | 5000~7500 | / | / |
| Anaerobic effluent | 800~1300 | / | 1988~2717 | / |
| Precipitate water outlet | 150~200 | / | / | 1401~1869 |
Wherein, with pre-acidified pond water inlet 700m3Meter, the complete 700m of workshop raw water3Any backflow is not carried out into pre-acidified pond
Regulation, then the COD level of the final waste water flowed out from pre-acidified pond is 5000~7500；And with workshop raw water 160m3, anaerobism goes out
Water flows back or precipitation effluent recycling 540m3Mixed, the COD level such as upper table of its waste water finally flowed out from pre-acidified pond,
It is apparent from, before IC reactors are entered, COD excursion can be more controlled by precipitating effluent recycling hybrid mode, and
Closer to the ideal response condition of IC reactors, treatment effeciency is improved.And if without flow back mixed processing, COD's
It is higher, processing time can be greatly prolonged, while can also cause whole system COD accumulation, is unfavorable for qualified discharge.And it is heavy
The pH value of shallow lake water outlet is general between 7.1~7.3, after backflow mixing, can reduce the chemicals usage of regulation pH value.
