1500mg/L or more cannot then digest completely often beyond 2~3 times of aerobic biochemical system design influent COD value and degradation has
Machine object.Most enterprises be all by high concentration sugar production wastewater and clear water mixed diluting at low concentration after, then using at aerobic biochemical
Reason can digest and degradation of organic substances although doing so, and realize discharged wastewater met the national standard；But treatment process is needed by a large amount of clear
Water and the biggish processing unit of investment, increase energy consumption and operating cost, and also reduce processing capacity.
Summary of the invention
It is an object of the invention in view of the above-mentioned drawbacks in the prior art, provide a kind of sugar industry wastewater processing unit
And method.
To achieve the above object, the present invention provides a kind of sugar industry wastewater processing unit, including be sequentially communicated every
Oil sump, cooling tower, souring tank, conditioning tank, TLP anaerobic reactor, settling tank, neutralization pond, oxidation ditch and sedimentation basin, by conditioning tank
It is provided with chemicals dosing plant, elevator pump is equipped between conditioning tank and TLP anaerobic reactor, connection blast aeration machine goes out in oxidation ditch
Port.
Sugar industry wastewater processing unit further includes sludge concentration tank and filter press, the sludge mouth and sludge condensation of sedimentation basin
The entrance in pond connects, and the outlet of sludge concentration tank and the entrance of filter press connect.It goes to decontaminate by sludge concentration tank and filter press
Muddy water point reduces sludge volume, reduces sludge subsequent processing expense.
Return pipe is communicated between TLP anaerobic reactor and settling tank and between oxidation ditch and sedimentation basin.
The present invention also provides a kind of sugar industry wastewater processing methods, comprising the following steps: by high concentration sugar industry
Waste water is passed through oil separator, removal suspended state oil and heavy oil；Then it sequentially enters cooling tower and is cooled to hydrolysis temperature, into souring tank
Middle hydrolysis into anaerobic digestion in TLP anaerobic reactor, and enters settling tank into pH value is adjusted in conditioning tank to neutrality
The first mud-water separation of middle progress；Supernatant obtained by first time mud-water separation enters neutralization pond, is also passed through low concentration system in neutralization pond
Sugar industry waste water is mixed；Mixing gained waste water enters in oxidation ditch, carries out catabolism using activated sludge, subsequently into
Second of mud-water separation is carried out in sedimentation basin, thus obtain can qualified discharge primary water.
The COD value of high concentration sugar industry wastewater is 300~3000mg/L, the COD value < of low concentration sugar industry wastewater
300mg/L。
Hydrolysis temperature is 35~36 DEG C, and addition acidification bacterium is hydrolyzed in souring tank and is hydrolyzed.
The resulting sludge reflux of first time mud-water separation is into TLP anaerobic reactor.
Sludge part obtained by second of mud-water separation is back in oxidation ditch, is partially drained into sludge concentration tank and is handled.Tool
The processing method of body is, by the sludge in concentration basin after gravity concentration, then transports outward after filter press filter-press dehydration.
Compared with the prior art, present invention has an advantage that
Sugar industry wastewater processing unit of the invention is rationally distributed, carries out sugar industry wastewater processing using the device,
It is that high concentration sugar industry wastewater is first successively passed through to oil separator, cooling tower, souring tank, conditioning tank, TLP anaerobic reactor and is sunk
Drop tank is handled, and the concentration of high concentration sugar industry wastewater is reduced, after then being mixed again with low concentration sugar industry wastewater,
Resulting waste water is mixed using aerobic treatment.After the acidified hydrolysis of high concentration sugar industry wastewater and anaerobic digestion, with
Aerobic treatment is carried out again after low concentration wastewater mixing, can not only be digested and degradation of organic substances, realizes discharged wastewater met the national standard；And
And relative to the method for being passed through clear water mixing, does not need to put into big processing equipment and the energy for mixed diluting, reduce energy
Consumption and operating cost, improve processing capacity.
Detailed description of the invention
In order to illustrate the technical solution of the embodiments of the present invention more clearly, below will be in embodiment or description of Related Art
Required attached drawing is briefly described.
Fig. 1 is the structural block diagram of sugar industry wastewater processing unit
Specific embodiment
To better understand the objects, features and advantages of the present invention, with reference to the accompanying drawing and specific real
It applies mode and further unrestricted detailed description is made to technical solution of the present invention.
As shown in Figure 1, a kind of sugar industry wastewater processing unit, including be sequentially communicated oil separator, cooling tower, acidification
Tank, conditioning tank, TLP anaerobic reactor, settling tank, neutralization pond, oxidation ditch and sedimentation basin are provided with chemicals dosing plant by conditioning tank,
Elevator pump is equipped between conditioning tank and TLP anaerobic reactor, the gas outlet of connection blast aeration machine in oxidation ditch.Sugar industry is useless
Water treatment facilities further includes sludge concentration tank and filter press, and the sludge mouth of sedimentation basin and the entrance of sludge concentration tank connect, sludge
The outlet of concentration basin and the entrance of filter press connect.Between TLP anaerobic reactor and settling tank and oxidation ditch and sedimentation basin it
Between be communicated with return pipe.
Above-mentioned sugar industry wastewater processing unit is used to carry out the specific steps of wastewater treatment are as follows: high concentration is refined sugar work
