A in A/O techniques represents anoxic section；First O represents oxidation of coal section, i.e., carbonaceous organic material is by oxidation removal；
In aerobic process, the path for transformation of organic matter is：
It proceeds as described above the microorganism of (oxidation of coal) and main body is accounted for different oxygen type and oxygen bacterium.Its main feature is that：
1. being food with organic matter, by providing metabolism required carbon source and the energy decomposition of organic matter；
2. can not only carry out aerobic respiration, but also anaerobic respiration (fermentation) can be carried out.
3. based on Zoogloea bacteria, there are also der Pilzs.
The path for transformation of ammonia nitrogen is：
The microorganism of nitrification is carried out based on autotrophic type aerobic bacteria.Its feature：
1. using inorganic carbon as the carbon source of cell growth；
2. generally obligate aerobic bacteria, is suppressed in anoxic；
3. perch is on activated sludge zoogloea surface, based on bacillus, coccus.
According to the above theoretical study results and engineering operation data, ring that oxidation of coal and nitrifying process have its best respectively
Border condition, there are certain contradictions for the requirement to carbon-nitrogen ratio, dissolved oxygen levels, i.e.,：In lower carbon-nitrogen ratio and higher dissolving
Under the conditions of oxygen, nitrifying bacteria community easily occupies advantage, and heterotroph is suppressed；On the contrary, in higher carbon-nitrogen ratio and lower dissolved oxygen
Under the conditions of, then it is heterotroph dominance, and nitrifier is suppressed.If mixed in aeration only there are one O sections in A/O techniques
Under the conditions of conjunction, entire O sections is equivalent to a complete mix flow (CSTR), and the environmental condition in reactor everywhere is homogeneous
Together.Under a given environmental condition, it is not that heterotroph is suppressed, is exactly that nitrifier is suppressed；Even if seeking to one
A environmental condition can make two kinds of floras reach dynamic equilibrium, and such environmental condition also only makes two kinds of floras by one
Fixed inhibition cannot respectively play most highly active.And such dynamic equilibrium also compares and is difficult to maintain, and the stability of water outlet does not have
It is secure.
Based on the above reason, we are divided into oxidation of coal section and nitration section by O sections.The carbon-nitrogen ratio of oxidation of coal section water inlet is relatively
Height, dissolved oxygen then cannot be excessively high, and heterotroph is made to occupy advantage in this section, play the removal effect to COD to the maximum extent.In nitre
Change section since most COD has been removed, water inlet carbon-nitrogen ratio is relatively low, and dissolved oxygen is then controlled in higher level, and ammonia nitrogen is made to be filled
Divide nitrification.In design aspect, oxidation of coal section is using BOD elimination capacities as main design parameters, and nitration section is then with rate of nitrification song master
Want design parameter.By optimization to reactor design parameter and operating parameter is separately controlled, makes oxidation of coal process and nitre
Change effect is attained by higher efficiency and removal rate.
The mixed-liquor return of nitration section is to A sections.Denitrification occurs at A sections, reaction process is：
By oxidation of coal-nitrification-denitrification process, landfill leachate organic matter and ammonia nitrogen are largely converted into inorganic matter
(C02, H20, N2) is removed from water, and sub-fraction is then converted into cellular material, is exhausted from system by regular spoil disposal.
Operation principle：
Landfill leachate enters treating stations through grid gravity flow, initially enters oil separation grit chamber, realizes preliminary separation of solid and liquid herein, goes
Except partial suspended thing, water outlet gravity flow is into regulating reservoir after separation, and the fully reconciliation of progress water quality and water is laggard in regulating reservoir
Enter subsequent treatment process.
The boosted pump of waste water in regulating reservoir is promoted to primary sedimentation tank and carries out coagulating sedimentation, and precipitation water outlet enters anaerobic reation pool
Waste water is hydrolyzed with anoxic pond, larger molecular organics are converted to the tractable organic matter of small molecule, anoxic pond be discharged into
Row reprecipitation, precipitation water outlet are reprocessed into biochemistry pool, and entering membrane biological reaction pond after biochemistry pool water outlet carries out depth
It can qualified discharge after reason water outlet.
The sludge gravity flow generated during landfill leachate treatment enters sludge-tank, sludge periodically outward transport processing.Sludge-tank
Supernatant is back to regulating reservoir.
The specific application example that the above is only the present invention, is not limited in any way protection scope of the present invention.All uses
Equivalent transformation or equivalent replacement and the technical solution formed, all fall within rights protection scope of the present invention.
