Description
Technical field
The present invention relates to a kind of waste water treatment process, especially a kind of technique using A/O method processing waste water.
Background technique
Sewage treatment is widely used in environmental protection, urban landscape, medical treatment, building, agricultural, traffic, the energy, food and drink, petrochemical industry
Etc. every field.Currently, sewage plant is had using wide denitrification dephosphorization technique: A2/O, SBR, oxidation ditch etc., these techniques are all
Be developed based on traditional nitration denitrification denitrogenation dephosphorization mechanism, but due to the nitrobacteria growth in these techniques compared with
Slowly, the sludge concentration and in the nitrifying process of traditional activated sludge process is lower, it is therefore desirable to the longer nitrification time, for
General sanitary sewage, it usually needs can just be nitrified for 5 hours or more, to increase investment and operating cost.Thus we
A kind of A/O waste water treatment process is had developed, harmful bacterium, virus etc. can be intercepted, and the microbial flora of decomposing pollutant
It is maintained in pond, achievees the effect that efficient degradation and separation of solid and liquid, occupied area are small.
Summary of the invention
A/O waste water treatment process is provided the invention aims to overcome the deficiencies in the prior art.
In order to achieve the above objectives, the technical solution adopted by the present invention is that: a kind of A/O waste water treatment process, which is characterized in that
It comprises the steps of:
Step 1: wastewater influent enters anoxic pond；
Step 2: enter the anoxic pond sewage, due to Organic substance in water be labyrinth and biodegradability it is poor, water
Solution acidification bacterium utilizes H2The H of O ionization+And OH-Ion opens the C-C key in organic molecule, C-C key one end of the opening
H is added+OH is added in ion, the other end-Long-chain can be hydrolyzed to short chain by ion, the hydrolysis acidification bacterium, and branch is hydrolyzed to directly
Chain, cyclic structure are hydrolyzed to linear chain or branched chain, to improve the biodegradability of sewage；When SS high in the sewage, hydrolysis
Acidification bacterium is captured SS by ectoplasm, is hydrolyzed into molecule part with exoenzyme, is then entered back into metabolism intracellular, incomplete generation
Thanking can make SS become dissolved organic matter；The anoxic pond has denitrification effect simultaneously；
Step 3: the sewage enters in the aerobic tank, and the aerobic tank is used for the organic matter gone in water removal, processing
Form is at least one of activated sludge tank, biological contact oxidation pond, the pond SBR, the pond MBR, and dissolubility described in step 2 is organic
After object handles 2-4 hours in aerobic tank, subsequent water outlet just becomes limpid；Sludge reflux in the aerobic tank is to the anoxic
In pond, the return sludge ratio is 1-3；
Step 4: the aerobic tank passes through the interception of submicron order fenestra, effectively removes organic matter, the You Haiwei in sewage
Biology, granule foreign, suspended matter etc. obtain good middle water water outlet.
Due to the application of the above technical scheme, compared with the prior art, the invention has the following advantages:
A kind of A/O waste water treatment process, biochemical reaction of the sewage Jing Guo anoxic pond and aerobic tank can intercept harmful thin
Bacterium, virus etc., and the microbial flora of decomposing pollutant is maintained in pond, reach the effect of efficient degradation and separation of solid and liquid
Fruit, occupied area are small.
