Abstract
The utility model belongs to the technical field of chemical equipment, relates to a waste water treatment system in a regenerative waste paper production process, and is aimed at solving the problem of existing waste water treatment systems in the regenerative waste paper production process that when a circulation anaerobic reactor works, anaerobic sludge in waste water is prone to calcification and scaling in the circulation anaerobic reactor and affecting the operation of the whole system. The waste water treatment system in the regenerative waste paper production process comprises a circulation aquage provided with a circulation anaerobic reactor, the circulation aquage further comprises a scale-borer which is connected with the circulation anaerobic reactor in series, the scale-borer comprises a water inlet port, a water outlet port and a funnel, and a top of the funnel is communicated with the water inlet port and the water outlet port. The technical scheme can be adopted to effectively solve the technical problem.
Description
Technical field
The utility model belongs to technical field of chemical, relates to the Waste Water Treatment in a kind of production recycled waste paper technology.
Background technology
Produce at present in the useless wastewater treatment process of recycled writing paper and extensively used circulation anaerobic reactor drum (this section is hereinafter to be referred as the IC reactor drum), this method can effectively reduce the COD content in the waste water, and can bear high-COD waste water and impact.But find at long-play with under following the tracks of; There is the calcification scale formation in anaerobic sludge in the IC reactor drum, and IC needs to pile up in the treatment reactor mud of calcification after operation for some time; To guarantee that the IC reactor drum can normally move; So just improved running cost, increased labor capacity, also brought certain potential safety hazard for Waste Water Treatment.
The utility model content
The utility model technical problem to be solved is that circulation anaerobic reactor drum in the Waste Water Treatment in the existing production recycled waste paper technology is when work; Anaerobic sludge in the waste water is calcification in the circulation anaerobic reactor drum easily; Loss of activity; Influence the problem of total system operation, and the Waste Water Treatment in a kind of production recycled waste paper technology is provided to this problem.
The utility model solves the problems of the technologies described above through following technical scheme:
Waste Water Treatment in a kind of production recycled waste paper technology; Comprise the circulation waterway that is provided with the circulation anaerobic reactor drum; It is characterized in that said circulation waterway also comprises the cleaner with the circulation anaerobic reactors in series; Said cleaner comprises feed-water end, water side and funnel, and said funnel top is communicated with feed-water end and water side.
After adopting said structure, the calcification anaerobic sludge in the waste water after operation for some time separates at the funnel place of cleaner and discharges from said Waste Water Treatment, avoids anaerobic sludge calcification accumulation in the circulation anaerobic reactor drum.
The mud density of part calcification becomes big in the said anaerobic sludge of the utility model; And rest part is by calcification, and density is less relatively, for ease of statement; The calcification bigger for those density partly is called heavy mud; Partly be not called light weight sludge by calcification and density is less, said light weight sludge is loss of activity not, the active sludge that can utilize once more.The utility model is found, because heavy mud is different with light weight sludge proportion, the mud of discharging through funnel is generally heavy mud; Yet; The waste water that is got into the funnel top by feed-water end forms eddy current, often produces certain cf-, and said cf-makes in the heavy calcification mud of discharge and contains the part light weight sludge; Finally causing the mud of discharging from funnel is not all to be heavy mud, thereby causes the waste of light weight sludge.
The utility model has been made further improvement project for this reason, and promptly said funnel bottom is provided with the balance mouth of a river.From the water flowing of the balance mouth of a river; Feed the pressure of water and the cf-of sludge settling from the balance mouth of a river and form a pair of approximate equilibrium power,, light weight sludge is effectively separated with heavy mud through adjusting to equilibrium water pressure; Colory light weight sludge is returned to the funnel top again; Simultaneously, the pressure of balance mouth of a river place's water flowing can stir the heavy mud that is positioned at funnel bottom, prevents that it from stopping up funnel.
For light weight sludge, a kind of like this structure of the utility model arrangement: said circulation waterway also comprises the sludge sump that is communicated with water side and circulation anaerobic reactor drum.Light weight sludge can finally be deposited in the sludge sump, in conjunction with cleaner, can realize the categorised collection of weight matter sludge.
Description of drawings
Fig. 1 is the Waste Water Treatment structural representation sketch (direction of arrow is that waste water flows among the figure) in the said a kind of production recycled waste paper technology of embodiment.
Embodiment
Embodiment
See Fig. 1; Waste Water Treatment in a kind of production recycled waste paper technology; Comprise be provided with circulation anaerobic reactor drum 1 and with the circulation waterway of circulation anaerobic reactor drum 1 placed in-line cleaner 6; Said circulation anaerobic reactor drum 1 is existing sewage treatment equipment, and said cleaner 6 comprises feed-water end 5, water side 4 and the funnel 8 that is structure as a whole with feed-water end 5 and water side 4, and said funnel 8 tops are communicated with feed-water end 5 and water side 4.
Said funnel 8 bottoms are provided with the balance mouth of a river 7, and said circulation waterway also comprises spiral pump 2 and the sludge sump 3 that is communicated with water side 4 and circulation anaerobic reactor drum 1.
Treating processes is carried out according to following process:
Open spiral pump 2, make the waste water circulation in the circulation waterway, according to the sedimentation speed of mud in the funnel 8, the water flowing speed at the adjustment mouth of a river 7 is to reach the good result of separation of heavy mud and light weight sludge.
More than show and described the advantage of ultimate principle, principal character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification sheets that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
