Abstract
A disclosed domestic waste leachate harmless treatment method is characterized in that: the soiling solution in the domestic waste is subjected to deposition layering and is divided into a grease layer, a sewage layer and a sludge layer which are respectively drawn out by an oil pump, a sewage pump and a sludge pump; grease is transferred to processing center and processed into lubricating oil; sewage is filtered, the filtered-out dirty slag is stirred with adobe materials for preparation of adobes, and the filtered sewage is discharged into a kiln for evaporation; and the sludge is prepared into adobes by a brickmaking machine and transferred into the kiln and further sintered into bricks. The technology of the invention is simple and clear, convenient to operate, low in cost and fast in effectiveness, and can be used for layering treatment on the soiling solution of the domestic waste and harmless treatment and utilization on the layered liquids.
Description
Technical field
The present invention relates to one way of life refuse treatment skill, be specifically related to one way of life percolate harmless treatment process.
Background technology
The rubbish in the many cities of China still has takes air storage mostly, without any safeguard procedures.Each place where the garage is piled up has become source of pollution, and mosquitos and flies evil is raw, and mouse causes disaster, and foul smell is boundless, and a large amount of garbage leachates are permeated the ground by earth's surface, and urban environment and underground water source are caused to severe contamination.
From existing market analysis, the processing of domestic refuse can be divided into three kinds, one, landfill disposal: be exactly landfill be the effective ways of domestic waste of dissolving in a large number, be also the final treatment process of all garbage treating process residuums, at present, China generally adopts direct landfill method; Two, burning disposal: burning method is that rubbish is placed in to High Temperature Furnaces Heating Apparatus, makes a kind of method that wherein combustiblecomponents is fully oxidized, and the heat of generation is for generating and heating; Three, compost treatment: domestic refuse is piled up in heaps, insulation is to 70 ℃ of storage, fermentation, and the ability by microorganism decomposition in rubbish, becomes inorganic nutrients by organic substance decomposing.And these three kinds of methods are all very general, owing to containing a large amount of soiling solutions in domestic refuse, these a large amount of soiling solutions can not get good solution, thereby do not reach the complete disposal and utilization of domestic refuse.
Summary of the invention
Technical problem to be solved by this invention is to provide one way of life percolate harmless treatment process, this technique is simple and clear, easy to operate, cost is low, instant effect, soiling solution in domestic refuse can be carried out to layering processing, and layering liquid is later carried out to harmless treatment and utilization.
Technical problem to be solved by this invention realizes by the following technical solutions,
One way of life percolate harmless treatment process, is characterized in that: this technique is carried out precipitated and separated by the soiling solution in domestic refuse, can be divided into oil layer, sewage layer and sludge blanket, and concrete technology step is as follows:
Step 1, domestic refuse is filled into the soiling solution in domestic refuse in hold tank by filtration unit, and by multi-charge ions deodorizing device, the peculiar smell in soiling solution is removed, in taste removal, soiling solution can precipitate automatically, precipitation can be divided into three layers later, the liquid of oiliness floats over the superiors of soiling solution, and sewage is positioned at middle layer, and the lowest layer is mud;
Step 2, first with the liquid that oil pump contains grease by the superiors, be extracted into and in Distallation systm, be processed into lubricating oil;
Secondly step 3, with sump pump, the sewage in middle layer is extracted in sand-bed filter and is filtered, after filtering, can be divided into dirty slag and soiling solution;
Step 4, finally with sludge pump by the mud sucking-off of the lowest layer, and add tackiness agent to be made into material brick.
Soiling solution in described step 3 is delivered in yin, yang ion exchange resin switch, and the sulfate ion in liquid is carried out to ion-exchange removal, then delivers in kiln body and evaporate.
Dirty slag in described step 3 is made adobe by brick press together with being stirred in adobe material after pulverizing, and adobe is delivered in kiln body and burnt till fragment of brick.
The invention has the beneficial effects as follows:
1, the present invention, by the soiling solution in domestic refuse by after precipitating, be divided into oil layer, sewage layer and sludge blanket, and the liquid that contains grease by three layers of corresponding Beng Shi the superiors has obtained effective utilization;
2, middle layer is divided into dirty slag and sewage by filtration, dirty ground-slag is broken to be stirred in and to have made adobe with other material, sewage makes its evaporation by delivering to after yin, yang ion exchange resin ion exchange treatment in kiln body, in utilization of waste material and recovery, from and can reach national environmental standard;
3, the mud of the lowest layer is made adobe by brick press;
4, simple and clear, easy to operate in technique of the present invention, cost is low, instant effect.

Embodiment
For technique means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
Embodiment 1
As shown in Figure 1, one way of life percolate harmless treatment process, this technique is carried out precipitated and separated by the soiling solution in domestic refuse, can be divided into oil layer, sewage layer and sludge blanket, and concrete technology step is as follows:
1., domestic refuse is filled into the soiling solution in domestic refuse in hold tank 1 by filtration unit, and by multi-charge ions deodorizing device 5, the peculiar smell in soiling solution is removed, in taste removal, soiling solution can precipitate automatically, precipitation can be divided into three layers later, the liquid of oiliness floats over the superiors of soiling solution, and sewage is positioned at middle layer, and the lowest layer is mud;
2., first with the liquid that oil pump 2 contains grease by the superiors, be extracted in Distallation systm 8 and be processed into lubricating oil;
3., secondly with sump pump 3, the sewage in middle layer is extracted in sand-bed filter 6 and is filtered, filter and can be divided into dirty slag and soiling solution afterwards;
4., finally use sludge pump 4 by the mud sucking-off of the lowest layer, and add tackiness agent to be made into material brick.
