Description
Technical field
The present invention relates to sewage treatment plant tail water further treatment techniques, pass through radiation treatment degradation sewage treatment plant's tail first
Hardly degraded organic substance carries out advanced treating subsequently into artificial wet land system, enhances artificial swamp denitrogenation as carbon source in water
Effect.
Background technique
The tail water of sewage treatment plant is river important supplement water source, effluent quality will directly affect the water quality in river with
The recovery of Ecology.Although traditional biochemical processes water outlet reaches the level-one A standard of urban wastewater treatment firm, COD
More than 1.5 times of surface water V class water body, TN is still surface water V class water more than five times.Therefore, sewage treatment plant tail water discharges
It is obvious to nutriments accumulative effects such as receiving water body Nitrogen In Sediment phosphorus, the eutrophication problem of receiving water body.
Artificial swamp there is Construction and operation to take low, the simple feature of management service is as typical eco-treatment technology
The main technique of American-European sewage plant Tailwater Depth processing.Traditional view thinks the denitrification process of artificial swamp, and main includes nitrification
With two steps of denitrification.Nitrification can be strengthened by intermittent duty and the use of vertical current constructed wetland, solve wetland
Limitation of the low-oxygen environment to nitrifying process, thus, denitrification is the critical issue of wetland denitrogenation urgent need to resolve.Denitrification process needs
Want organic carbon as electron donor, to restore nitrate nitrogen.Since sewage plant tail water has gone through the aerobic removal rank of organic matter
Section, therefore degradable content of organics is lower, and organic carbon mostly difficult to degrade, limits subsequent artificial swamp denitrification speed
Rate reduces denitrification effect.Therefore, carbon source deficiency becomes the major limiting factors of Nitrogen Removal Effect in Constructed Wetland.To understand
Certainly this problem, the measure used at this stage are mainly the nitric efficiency for enhancing wetland by adding exogenous carbon.And it throws
Add exogenous carbon higher cost or operational effect unstable.
Summary of the invention
The present invention in view of the shortcomings of the prior art, propose it is a kind of using irradiation apparatus degradation tail water in hardly degraded organic substance discharge
Carbon source provides the combined method of carbon source for artificial swamp denitrification；This method has without adding carbon source, nitric efficiency height, operation
Management is simple, can be applied to sewage treatment plant tail water advanced treating.
The technical solution adopted by the present invention:
A method of using irradiation-Combination System of Constructed Wetland enhanced sewage treatment plant's Tailwater Depth processing, using electron beam
Radiation treatment and artificial wet land system tandem compound processing mode use spoke before tail water enters artificial wet land system first
Radiation treatment is carried out to the tail water discharged from sewage treatment plant according to equipment, is degraded to organic matter difficult to degrade in tail water small
Middle Molecular Substance, so that carbon source is provided for microorganism anti-nitration reaction, subsequently into the further advanced treating of artificial wet land system.
During radiation treatment, tail water is set to absorb 0.5~3 kGy of irradiation dose by controlling irradiation time.
It is irradiated treated tail water and enters artificial swamp inlet distribution water pipe after sewage pump is promoted and carry out water distribution,
Hydraulic detention time in artificial swamp is 1~5d, BOD520~60g/ of load (m2·d)。
The method handled using irradiation-Combination System of Constructed Wetland enhanced sewage treatment plant's Tailwater Depth, it is described
Artificial wet land system kind is implanted with water plant, and water plant is cattail, calamus, canna, thaliadeabata, Lythrum salicaria, reed, shuttle
In water shield any one or it is two or more.
Denitrifying microorganism carries out denitrification using the carbon source that irradiation generates inside artificial swamp, improves the denitrogenation of wetland
Effect.By the tail water of artificial wet land system advanced treating, discharge or greening water or flushing supply after being collected by outlet pipe.
Invention the utility model has the advantages that
1, sewage treatment plant tail water deep treatment method of the present invention, first with difficult to degrade organic in irradiation devices degradation tail water
Object makes it be degraded to small molecular weight material, serves as the carbon source of subsequent anti-nitration reaction；This method solve existing artificial swamp systems
The problem of system needs additional carbon has the characteristics that nitric efficiency is high, operational management is simple, system water outlet can be effectively reduced
COD and TN content.
2, sewage treatment plant tail water deep treatment method of the present invention, be irradiated processing tail water using artificial wet land system into
Row advanced treating has many advantages, such as that operational management is easy, operating cost is low, environmentally friendly.
Specific embodiment
