Abstract
The invention discloses a kind of percolate secondary treatment method, comprise the following steps：S1) percolate Jing Guo biochemical treatment passes sequentially through first flow valve, the first booster pump into dish tube type membrane system, obtain a supernatant and the retention dope containing organic matter, supernatant is delivered to the processing unit of next stage, and retention dope is delivered to dope water tank；S2) the retention dope of dope water tank passes sequentially through the second booster pump, second flow valve and is delivered to the entrance side of the first booster pump, is mixed with the percolate Jing Guo biochemical treatment, enters dish tube type membrane system via the first booster pump；S3 secondary supernatant and high concentration retention dope) are obtained, secondary supernatant is delivered to the processing unit of next stage, and high concentration retention dope is transmitted back to dope water tank.The present invention is filtered by secondary booster, and by the filtering of circulation, concentrated water is further concentrated, and reduces the yield of concentrated water, is improved the concentration of concentrated water after filter membrane, the yield of clear water is also improved.
Description
Technical field
The present invention relates to advanced treatment of wastewater technical field, more specifically a kind of percolate after-treatment side
Method.
Background technology
House refuse is during stacking, filling, due to anaerobic fermentation, organic matter decomposition, the immersion of rainwater shower, underground water
Deng a variety of metabolites and moisture is produced, percolate is formed.Percolate processing is the important step of sewage disposal, if place
Reason is not thorough, and immeasurable pollution and harm can be brought to surrounding environment, threat is brought to health.Sewage is carried out deep
The equipment of processing is spent, the producing water ratio of advanced treating, the garbage filter of especially suitable house refuse power generation project can be effectively improved
Liquid processing.At present, the sewage that house refuse power generation project is produced typically is entered using the technique of " physics+biochemistry+MBR+ film process "
Row processing, using above-mentioned processing method, exist generation concentrated water amount it is larger, concentration is relatively low, the problem of producing water ratio is relatively low.
The content of the invention
The purpose of the present invention aim to provide it is a kind of can the high percolate after-treatment of output high concentration dope, producing water ratio
Method, to overcome weak point of the prior art.
To achieve the above object, technical scheme provided by the present invention is：A kind of percolate secondary treatment method, its
It is characterised by comprising the following steps：
S1) dish periosteum is filtered：Percolate by biochemical treatment passes sequentially through first flow valve, the first booster pump and enters dish
Tube type membrane system, obtains a supernatant and the retention dope containing organic matter, and a supernatant is delivered to the processing of next stage
Unit, retention dope is delivered to dope water tank；
S2) secondary back is filtered：The retention dope of dope water tank passes sequentially through the second booster pump, second flow valve and is delivered to
The entrance side of one booster pump, is mixed with the percolate Jing Guo biochemical treatment, enters dish tube type membrane via the first booster pump
System；
S3 secondary supernatant and high concentration retention dope) are obtained, secondary supernatant is delivered to the processing unit of next stage, highly concentrated
Degree retention dope is transmitted back to dope water tank.
Pressure-detecting device is set in the dish tube type membrane system.
The dope water tank sets concentration detection apparatus.
The beneficial effects of the invention are as follows：
The present invention is filtered by secondary booster, and by the filtering of circulation, concentrated water is further concentrated, the yield of concentrated water is reduced,
The concentration of concentrated water after filter membrane is improved, the yield of clear water is also improved.
Meanwhile, the present invention is simple in construction, as long as by circulating line, concentrated water is passed to before high-pressure pump, original is made in the duct
Water is mixed with concentrated water, passes to film processing system.Supercharging equipment and mixing arrangement need not additionally be increased, with traditional one-level mistake
Filter is compared, without extra increase power-equipment.
Brief description of the drawings
Fig. 1 is the flow chart of percolate secondary treatment method of the present invention.
Embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention is described in detail.
Referring to Fig. 1, a kind of percolate secondary treatment method comprises the following steps：
S1) dish periosteum is filtered：Percolate by biochemical treatment passes sequentially through first flow valve 4, the first booster pump 5 and entered
Dish tube type membrane system 1, obtains a supernatant and the retention dope containing organic matter, one time supernatant is delivered to the upper of next stage
Clear liquid processing unit 2, retention dope is delivered to dope water tank 3；
S2) secondary back is filtered：The retention dope of dope water tank 3 passes sequentially through the second booster pump 7, second flow valve 6 and is delivered to
The entrance side of first booster pump 5, is mixed with the percolate Jing Guo biochemical treatment, enters dish tubular type via the first booster pump 5
Filter membrane system 1；
S3 secondary supernatant and high concentration retention dope) are obtained, secondary supernatant is delivered to the processing unit of next stage, highly concentrated
Degree retention dope is transmitted back to dope water tank.
The present invention to percolate take concentration dope secondary filter concentrate the step of, this method have it is easy to operate,
Economical and efficient, saving power and preventing pollution dye, the advantages of practical, it is removed as a kind of further treatment technique, effectively has in percolate
Machine thing dope, can be very good to make up the deficiency in existing consumer waste infiltration liquid treatment technology, reaches landfill leachate treatment
To the target of " zero-emission ".
Pressure-detecting device is set in the dish tube type membrane system, by the valve opening for controlling first and second flow valve
The pressure limit in system is set to be suitable to filtering.The dope water tank sets concentration detection apparatus, when the concentrated water in dope water tank and
When concentration reaches processing requirement, then the dope of dope water tank is uniformly processed.
Although an embodiment of the present invention has been shown and described, it will be understood by those within the art that：Not
In the case of departing from the principle and objective of the present invention a variety of change, modification, replacement and modification can be carried out to these embodiments, this
The scope of invention is limited by claim and its equivalent substitution, without creative work improvements introduced etc., all should be included
Within protection scope of the present invention.
