Background technique
According to the principle of China's garbage disposal " recycling, minimizing, innoxious ", most domestic city, which is usually taken, to be defended
The mode of raw landfill handles house refuse.And whether landfill leachate handles qualified discharge, be measure landfill yard whether be
One of important indicator of sanitary filling field.Due to not taking seepage control measure, the percolate of generation seeps for some old refuse landfills
Enter in underground water, causes the serious pollution to underground water.It pollutes time duration many decades or even upper a century, seriously threatens people
Production and life.
The traditional treatment method of landfill leachate has materialization treatment process and biological treatment, and materialization treatment process includes chemical oxygen
Change method and membrane technology etc., wherein chemical oxidation needs to put into a large amount of medicament, and film process is related to high concentration concentrate
Processing up to standard, application are all subject to certain restrictions；Biological treatment generally has Aerobic Process for Treatment method and Anaerobic Treatment method, is that rubbish seeps
Filtrate handles most common method, but is also limited by Biodegradability of Wastewater.
Summary of the invention
To solve the above problems, the present invention provides a kind of Landfill Leachate Pollution water body treatment process, which is directed to
By the water body that high-concentration garbage percolate pollutes, have the characteristics that the pollution scale of construction is big, pollution level is not relatively high, the present invention uses
Materilization freatment method have the advantages that at low cost, easy to operate, practical, obvious processing effect, may be implemented rubbish infiltration
The improvement up to standard of filtrate contamination water body.
The object of the present invention is achieved like this:
A kind of Landfill Leachate Pollution water body treatment process, which comprises the steps of:
1) sewage is removed into large granular impurity by grid；
2) dosing coagulant in step 1) treated sewage, forms flock；
3) by step 2), treated that sewage is passed through geotextile tube bag, and wadding body is trapped in pipe bag, and sewage is through pipe bag gap
Outflow；
4) treated that sewage enters active carbon pond for step 3), filters through activated carbon adsorption, completes sewage treatment.
A kind of Landfill Leachate Pollution water body treatment process of the invention should adopt the following technical scheme that
A kind of Landfill Leachate Pollution water body treatment process, which is characterized in that the grid grizzly bar clear spacing is
16 millimeters.
A kind of Landfill Leachate Pollution water body treatment process, which is characterized in that coagulant dosage mode is pipeline
It adds, order of adding are as follows: first add aluminium polychloride, the reaction time 1 minute, then polyacrylamide is added, the reaction time is greater than 2
Minute.Coagulating is water-borne glue body particle destabilization process, is mainly realized by neutralizing colloidal electric charge, is mixed by pipeline
So that the particle for losing charge is contacted with each other and is flocked together, formed floccule, these wadding bodies pass through in subsequent processing precipitating,
Removal is obtained by filtration.
A kind of Landfill Leachate Pollution water body treatment process, which is characterized in that geotextile tube bag divides into antiseepage dehydration
Place and charge for remittance system, seepage control system use 2 millimeters thick HDPE films.Sewage after coagulating is filled to geotextile tube
Bag carries out retention sludge using fluid pressure in filter structure possessed by geotextile tube bag and bag and is dehydrated.The dehydration of geotextile tube bag
It is not required to special building, it is only necessary to carry out Anti-seeping technology and construction charge for remittance system to field is stacked.
A kind of Landfill Leachate Pollution water body treatment process, which is characterized in that sewage is in the active carbon pond
Residence time be 10~20 minutes.
A kind of Landfill Leachate Pollution water body treatment process, which is characterized in that in geotextile tube bag after sludge drying
Landfill stabilization.
The beneficial effects of the present invention are: being directed to the water body poor by the biodegradability of Landfill Leachate Pollution, one is proposed
The treatment process of coagulation, filtering, activated carbon adsorption is planted, the technique is low, easy to operate, practical with processing cost, handles
The improvement up to standard of Landfill Leachate Pollution water body may be implemented in the advantages of significant effect, and the present invention is in Landfill Leachate Pollution water
Body process field has broad application prospects.
Detailed description of the invention
Fig. 1 is a kind of Landfill Leachate Pollution water body processing technological flow figure of the invention.
Specific embodiment
In the following with reference to the drawings and specific embodiments to a kind of Landfill Leachate Pollution water body treatment process provided by the invention
It is described in detail.
As shown in Figure 1, a kind of Landfill Leachate Pollution water body treatment process, includes the following steps: that sewage 1) is passed through lattice
Grid remove large granular impurity；2) dosing coagulant in sewage forms flock, and coagulant dosage mode adds for pipeline, throws
Add sequence are as follows: first add aluminium polychloride, the reaction time 1 minute, then polyacrylamide is added, the reaction time is greater than 2 minutes, leads to
Piping mixing makes the particle for losing charge contact with each other and flock together, and forms floccule, these wadding bodies are in subsequent processing
In by precipitating, removal is obtained by filtration；3) it will be filled to geotextile tube bag by the sewage of coagulating, is had using geotextile tube bag
Fluid pressure carries out retention sludge and is dehydrated in some filter structures and bag, and wadding body is trapped in pipe bag, and sewage is stitched through pipe bag
Clearance flow goes out, and the dehydration of geotextile tube bag is not required to special building, it is only necessary to carry out Anti-seeping technology and construction charge for remittance system to field is stacked；4)
Sewage enters active carbon pond, and the residence time in active carbon pond is 10~20 minutes, is filtered through activated carbon adsorption, completes sewage
Processing.
It is intended to further illustrate the present invention with reference to embodiments, is not intended to limit the present invention.
Example 1
Certain lake water is by Landfill Leachate Pollution, contamination index: COD CODCrFor 174mg/L, biochemical oxygen demand (BOD)
BOD5It is 210mg/L for 35mg/L, suspended solid SS, coloration is 200 times.Sewage is carried out using the technique of offer of the invention
Processing.
Specific implementation process is as follows:
By sewage by grid, large granular impurity is removed.Aluminium polychloride is added in sewage using pipeline dosing method,
Reaction time 1 minute, then polyacrylamide is added, the reaction time 2 minutes.Sewage after coagulating is filled to geotechnique
In pipe bag, retention sludge is carried out using fluid pressure in filter structure possessed by geotextile tube bag and bag and is dehydrated, wadding body is cut
It stays in pipe bag, sewage is flowed out through pipe bag gap.The sewage that geotextile tube bag is flowed out imports active carbon pond, and sewage is in active carbon pond
It is middle to stop 12 minutes, it is flowed out after activated carbon adsorption is filtered, completes sewage treatment.
After treatment, it is discharged COD CODCr100mg/L is reduced to hereinafter, biochemical oxygen demand (BOD) BOD5It is reduced to 20mg/L
Hereinafter, suspended solid SS is reduced to 70mg/L hereinafter, coloration is reduced to 50 times hereinafter, completing the processing up to standard of sewage.
