Description
Technical field
The utility model is related to field of garbage disposal, more particularly to a kind of garbage leachate treatment device.
Background technology
Landfill leachate is a kind of high concentrated organic wastewater for complicated component that rubbish generates in the process in landfill, main next
Come from that precipitation penetrates into, organic matter decomposes and rubbish interior aqueous etc. in itself.It is directly discharged as not being pocessed and easily triggers ground
Lower water, surface water pollution, and then jeopardize health.Present people will be discharged using various equipment after landfill leachate treatment,
Although cleaning percolate, due to processing during do not have to focus on recycling to salinity in percolate, certain
The wasting of resources is also resulted in degree.
Therefore, the wasting of resources can be caused by being had using existing landfill leachate treatment equipment progress landfill leachate treatment
The shortcomings that.
Utility model content
The purpose of this utility model is that provide a kind of landfill leachate multi-stage treatment units.It can by the utility model
To recycle the salinity in landfill leachate, reduce the waste of resource.
The technical solution of the utility model：A kind of landfill leachate multi-stage treatment units, including continuous filter, the bottom of continuous filter
Portion is equipped with outlet of sewer, outlet of sewer connection sand filter, and sand filter connects membrane filter through oil and water filters, and membrane filter includes
First concentrated water import of the outlet of the second concentrated water, the clear water output of connection degassing tower and connection oil and water filters；Second concentrated water exports
Boiler is connected through catalytic wet oxidation system, boiler includes burner and container, and container, which is equipped with, receives salt mouth, connection catalytic wet oxygen
The saline solution import of change system and the steam (vapor) outlet of connection degassing tower.
In foregoing landfill leachate multi-stage treatment units, the catalytic wet oxidation system connects salt through ceramic filter
Liquid import.
In foregoing landfill leachate multi-stage treatment units, the water outlet of the degassing tower is equipped with quality alarm.
Compared with prior art, the utility model was by being reasonably classified the particulate matter progress in landfill leachate
Filter ensure that the service life of device, and fuel used burner is rubbish in continuous filter, and the salinity of output is come from as garbage filter
Liquid had not only handled rubbish but also had recycled the salinity in rubbish.It is first by a part of water in membrane filter landfill leachate
Into degassing tower, the fuel handled used in identical heavy landfill leachate boiler is few, and also improves the processing speed of percolate
Degree.Since degassing tower connects steam (vapor) outlet, the temperature of degassing tower is higher, and degassing efficiency is high so that the speed of percolate processing is fast.
Therefore, the salinity in landfill leachate can be recycled by the utility model, reduces the waste of resource.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Mark in attached drawing for：1- continuous filters, 2- outlets of sewer, 3- sand filters, 4- oil and water filters, 5- membrane filters,
The second concentrated waters of 6- export, 7- degassing towers, 8- clear water outputs, 10- the first concentrated water imports, 11- catalytic wet oxidation systems, 13- combustions
Stove, 14- containers, 15- receive salt mouth, 16- saline solution imports, 18- steam (vapor) outlets, 19- ceramic filters, 20- quality alarms.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model
The foundation of limitation.
Embodiment.A kind of landfill leachate multi-stage treatment units, as shown in Figure 1, including continuous filter 1, the bottom of continuous filter 1
Equipped with outlet of sewer 2, outlet of sewer 2 connects sand filter 3, and sand filter 3 connects membrane filter 5, membrane filter through oil and water filters 4
5 are equipped with the second concentrated water outlet 6, connect the clear water output 8 of degassing tower 7 and connect the first concentrated water import 10 of oil and water filters 4；
Second concentrated water outlet 6 connects boiler through catalytic wet oxidation system 11, and boiler includes burner 13 and container 14, and container 14 is equipped with
Receive the steam (vapor) outlet 18 of salt mouth 15, the saline solution import 16 of connection catalytic wet oxidation system 11 and connection degassing tower 7.
The catalytic wet oxidation system 11 connects saline solution import 16 through ceramic filter 19.
The water outlet of the degassing tower 17 is equipped with quality alarm 20.
Operation principle：Rubbish is positioned in continuous filter, landfill leachate flows into sand filter through outlet of sewer, then flows into oil
Water filter, then export to flow into membrane filter through the first concentrated water and be filtered, the clear water after filtering flows into de- through clear water output
Gas tower is de-gassed, and fails to carry out into catalytic wet oxidation system through the outlet of the second concentrated water by the landfill leachate of filtering anti-
Should, then flowed into through ceramic filter in container, steam enters degassing tower after being heated into the landfill leachate in container, remaining
Salinity by receive salt mouth recycle, degassing tower to water body deaerate after by the landfill leachate handled well discharge, when discharge water quality not
Quality alarm warning worker in time carries out maintenance device when qualified.Sand filter is by the big particle object mistake in landfill leachate
Filter；Oil and water filters filter out oil body in landfill leachate, prevent that oil blocks membrane filter in later process；Membrane filter is again
Filter out tiny particles content；Ceramic filter filters out the suspended matter and particulate matter formed after catalysis oxidation again, prevents from recycling
Salinity sundries it is excessive；The fuel that burner uses is the rubbish in continuous filter.
The utility model ensure that making for device by carrying out rational classified filtering to the particulate matter in landfill leachate
With the service life, fuel used burner is rubbish in continuous filter, and it is landfill leachate that the salinity of output, which comes from, had not only handled rubbish but also had returned
The salinity in rubbish is received.Degassing tower is introduced by a part of water in membrane filter landfill leachate, processing is identical
Fuel used in the landfill leachate boiler of weight is few, and also improves the processing speed of percolate.It is steamed since degassing tower connects
Vapor outlet, the temperature of degassing tower is higher, and degassing efficiency is high so that the speed of percolate processing is fast.
Therefore, the salinity in landfill leachate can be recycled by the utility model, reduces the waste of resource.
