Description

A kind of Sewage and reclamation set

Technical field

The utility model belongs to technology for the treatment of of papermaking wastewater field, fills more particularly, to a kind of Sewage and reuse It sets.

Background technique

Management in view of present Environmental increases, and the requirement to enviromental protection enterprise is higher and higher.Making at this stage Paper sewage is usually by addition additive and to pass through precipitation process, reaches direct emission after discharge standard, although in this way can It meets environmental requirements, but causes the waste of a large amount of useful raw materials and water resource in sewage；Therefore, classification is segmented to sewage to receive Collection and reutilization measure, the water consumption for reducing enterprise and pollution treatment burden abundant are become using the useful substance in sewage Urgent problem to be solved.

Summary of the invention

The purpose of this utility model is that improving the deficiency of prior art and providing a kind of production cost of reduction product, subtract The pollution treatment pressure of few company and reusing sewage after cost, filtration treatment to paper manufacturing systems, take full advantage of water resource, alleviate The insufficient Sewage of enterprise water use and reclamation set.

The purpose of this utility model is achieved in that a kind of Sewage and reclamation set, its main feature is that including Screen mat, conditioning tank, anaerobic pond, aerobic tank, secondary settling tank, sludge concentration tank, filtering tank, recycle-water storage pool, in which:

Screen mat passes through Pipeline transport to conditioning tank after filtering production waste；The sewage of collection is passed through water by conditioning tank It is pumped into anaerobic pond, sludge is pumped to sludge concentration tank by sludge pump；Sewage in anaerobic pond is stirred dirty by impeller Mud flows automatically to aerobic tank after decomposing；For aerobic tank by sewage aeration catalytic oxidation, top sewage passes through aerobic tank top water outlet certainly It flows to secondary settling tank, middle part and following sewage and is returning anaerobic pond by the water pump pumps in the middle part of aerobic tank；The sewage of secondary settling tank passes through Precipitating, advanced treating rear portion are discharged into filtering tank by pipeline, and another part is discharged into municipal sewage plant, the dirt of precipitating Mud is divided into three parts, and a part returns conditioning tank, third by Pipeline transport by Pipeline transport to sludge concentration tank, another part Part passes through Pipeline transport to anaerobic pond；Filtered water is simultaneously delivered to reuse by pipeline by impurity that filtering tank is crossed in drainage The storage of water storage pool；The sewage of sludge concentration tank flows back into conditioning tank by pipeline, the sludge pumping in sludge concentration tank to pressure Filter proposes.

Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model is using filtering Slurry and compared with bigger material in aperture plate filter sewage, conditioning tank collects sewage and sludge, anaerobic pond resolve into macromolecule contaminant Low molecular weight pollutant, aerobic tank is by sewage aeration catalytic oxidation, and secondary settling tank makes to precipitate and collect sludge, and sludge concentration tank will be dirty Mud is concentrated, the impurity in filtering tank filtering in water, and the middle water of recycle-water storage pool storage filtering, is to pass through sewage above The Treated sewage reusing filtering, collect, decomposing, aoxidizing, precipitating, refiltering out realizes papermaking wastewater into paper manufacturing systems each process For treatment for reuse system to the purpose that the classification of moisture section is collected and recycled after filtering, water consumption and the pollution treatment for both having reduced enterprise are negative Load, it is also abundant to utilize water resource, achieve the purpose that reduce cost.

Detailed description of the invention

The utility model is described in further details with reference to the accompanying drawings and examples.

Fig. 1 is a kind of structural schematic diagram of the utility model.

Specific embodiment

A kind of Sewage and reclamation set, referring to Fig.1, including it is screen mat 1, conditioning tank 2, anaerobic pond 3, aerobic Pond 4, secondary settling tank 5, sludge concentration tank 6, filtering tank 7, recycle-water storage pool 8, in which:

Screen mat 1 passes through Pipeline transport to tune for filter sewage slurry and compared with bigger material after filtering production waste Save pond 2；Conditioning tank 2 collects each process sewage and sludge, and by the sewage of collection by water pump pumps to anaerobic pond 3, sludge passes through Sludge pump is pumped to sludge concentration tank 6；Macromolecule contaminant is resolved into low molecular weight pollutant by anaerobic pond 3, and sewage is led to Aerobic tank 4 is flowed automatically to after crossing impeller stirring sludge disintegration；Aerobic tank 4 passes through sewage aeration catalytic oxidation, top sewage Oxygen pond top water outlet pipeline flows automatically to secondary settling tank 5 and carries out subsequent processing, middle part and following sewage by the middle part of aerobic tank Water pump pumps return anaerobic pond, and microorganism is allowed to better conform to grow；The sewage of secondary settling tank 5 passes through pipe after precipitating, advanced treating Road is discharged into filtering tank 7 and municipal sewage plant, and the sludge of precipitating is divided into three parts, and a part passes through Pipeline transport to sludge Concentration basin 6 carries out subsequent processing, and another part returns conditioning tank 2 as adsorbent material by Pipeline transport and continues to use, third portion Divide through Pipeline transport to anaerobic pond 3 with the sludge is stable in the system of maintaining；Filtering tank 7 cross drainage in impurity and pass through pipeline Filtered water is delivered to recycle-water storage pool 8 to store；The sewage of sludge concentration tank 6 flows back into conditioning tank 2 by pipeline, dirty Sludge pumping in mud thickener 6 is proposed to filter press.

Claims (1)

1. a kind of Sewage and reclamation set, it is characterized in that including screen mat, conditioning tank, anaerobic pond, aerobic tank, two Heavy pond, sludge concentration tank, filtering tank, recycle-water storage pool, in which:

Screen mat passes through Pipeline transport to conditioning tank after filtering production waste；Conditioning tank pumps the sewage of collection by water pump It is sent to anaerobic pond, sludge is pumped to sludge concentration tank by sludge pump；Sewage in anaerobic pond stirs sludge point by impeller Aerobic tank is flowed automatically to after solution；Aerobic tank flows automatically to sewage aeration catalytic oxidation, top sewage by aerobic tank top water outlet Secondary settling tank, middle part and following sewage are returning anaerobic pond by the water pump pumps in the middle part of aerobic tank；The sewage process precipitating of secondary settling tank, Advanced treating rear portion is discharged into filtering tank by pipeline, and another part is discharged into municipal sewage plant, the sludge point of precipitating For three parts, a part returns conditioning tank, Part III by Pipeline transport by Pipeline transport to sludge concentration tank, another part Pass through Pipeline transport to anaerobic pond；Filtered water is simultaneously delivered to recycle-water storage by pipeline by impurity that filtering tank is crossed in drainage Deposit pond storage；The sewage of sludge concentration tank flows back into conditioning tank by pipeline, the sludge pumping in sludge concentration tank to filter press It proposes.
