Description of the drawings
Fig. 1 is initial stage garbage percolation liquid treating system flow chart.
Specific implementation mode
It is proposed a kind of high treating effect in conjunction with attached drawing this patent, save money but can reuse initial stage landfill leachate treatment
System.
This system mainly include regulating reservoir, UASB equipment, A/O biochemistry pools, MBR equipment, NF equipment, upstriker wetland, under
Line wetland, photovoltaic generating system, control system, this system are worked by control system.
The landfill leachate at initial stage is entered regulating reservoir, regulating pondage by newly-built refuse landfill by catheter collection gravity flow
It is promoted in UASB equipment processing systems by elevator pump with after water quality, since the COD and SS of initial stage landfill leachate are higher,
Therefore it can effectively be degraded most organic matter and SS by Anaerobic Treatment, reduce follow-up nitrification, denitrification and MBR equipment
Energy consumption.The organic nitrogen of part is converted into inorganic nitrogen in anaerobic processes, and corresponding NH3-N concentration will increase, but due to subsequently adopting
Ammonia nitrogen can be converted into nitrogen removal using the method for biology completely with nitration denitrification technique.The water outlet of UASB equipment flows into certainly
Enter nitration denitrification pond, biochemical organics removal and ammonia nitrogen and total nitrogen；Enter MBR equipment system through nitrifying biochemical treatment water outlet gravity flow
System, membrane bioreactor（MBR）It is mainly made of membrane module and bioreactor two parts, a large amount of microorganism（Activated sludge）
It is come into full contact with matrix in bioreactor, by oxygenolysis progress metabolism to maintain own growth, breeding,
Make organic pollutant degradation simultaneously.Membrane module carries out solid-liquid by the effects that mechanical grading, retention to waste water and mud mixed liquid
Separation, macromolecular substances etc. return to bioreactor after being concentrated, so as to avoid the loss of microorganism.Membrane module is equivalent to biography
The secondary settling tank for technique of uniting, but overcome many disadvantages of traditional secondary settling tank.The water outlet of MBR equipment is pumped into water tank by self priming pump, then
Enter NF equipment i.e. nanofiltration system through booster pump, most COD, BOD, NH3-N, TN, SS, a huge sum of money are removed by nanofiltration system
Belong to, the pollutants such as Escherichia coli and coloration, the concentrate of nanofiltration system is transported to landfill area landfill by fecal suction truck, is discharged from flowing into
In line and downstriker wetland, wetland selects five layers of complex media, and it is 90cm to lay height, by the further mistake of PKA wetlands
The pollutants such as remaining organic matter, nitrogen, phosphorus, pathogen in water removal are filtered off, final outflow water is made to rinse, flush the toilet or irrigate as road
Deng use.The form that all power supply system electricity consumptions are all made of photovoltaic generation wherein in whole system and city is electrically coupled eliminates partially
Remote area is difficult to the obstacle being powered.
A/O biochemistry pools and MBR equipment described in this system are respectively connected with air blower, the effect of air blower：First, to life
Change aerobic bacteria and increase oxygen, ensures their living environments, reach the needs of sewage disposal；Second is that ventilation, since sewage disposal is more
Number all uses biochemical reaction, will produce some biogas and other decomposition gases, and the smell is awful simultaneously with certain danger,
In order to ensure safety and improve environment, site environment is aerated.
This system to initial stage landfill leachate in biochemical treatment, by adding the nutrient solution in trophic system in biochemistry pool
Activity to improve microorganism is improved to the removal rate of COD, ammonia nitrogen, COD, ammonia nitrogen removal rate be 80-90% or so, water outlet is full
Sufficient film process inflow requirement.The form of MBR equipment includes a variety of configurations such as immersion, flat, and membrane module uses PVDF materials,
Microbial cells are detached by efficient MBR membrane modules from water outlet, it is ensured that are more than 0.02 μm of particulate matter, microorganism and and COD
Relevant suspended matter is safely trapped in system, and sludge concentration is maintained by the continuous recycle stream of aeration of cross-current type.MBR
Device program stops after running 10-20min after starting with certain flow supply purging pocket, and self-priming pump operation is after 2-3 minutes
Stopping restarts again, continuous circular flow.Nanofiltration system includes chemicals dosing plant, cartridge filter, high-pressure pump, NF membrane etc.,
Using the principle of modularized design Automatic Control, system, by the switching of different valves, starts " anti-after running a period of time
The program of flushing-gas flushing-flushing-operation ", the not outer row of system concentrated water in normal operation, only opens " backwash-in system
There is partial concentration waste water to be back to regulating reservoir when gas flushing-just flushing " program to be handled again, NF membrane has higher through speed
Degree, desalting performance is strong, mechanical strength is good, the high feature of antifouling property.The side that PKA wetlands are combined using upstriker and downstriker
Formula, it is overpunching water distribution that medium, which uses five layers of complex media, pipe arrangement, and the operation logic that underpunch is catchmented goes out nanofiltration
Water is further filtered, wherein to the removal rate 80-90% of COD, ammonia nitrogen.
The initial stage garbage percolation liquid treating system have high treating effect, save money, it is processed after water can reuse
Feature, this system can not only reduce the waste of water resource, moreover it is possible to realize recycling for water resource.
