Description
Technical field
The present invention relates to technical field of sewage, and in particular to a kind of multifunctional assembled Tailwater Depth denitrogenation dephosphorizing people
Work wet land system.
Background technique
Wastewater treatment in China plant effluent water quality generally executes " urban wastewater treatment firm pollutant emission standard " at present
(GB18918-2002) level-one A or B standard in.But many town sewage plants are because of sewage treatment process and processing equipment
Unreasonable, so that sewage treating efficiency is low, energy consumption is high for processing, and a large amount of sewage plant tail water is directly discharged to receiving water body.It is dirty
Water treatment plant's tail water still has more pollutant, is with earth's surface Group III water although most of can reach discharge standard
Example, sewage effluents concentration are that (COD is 3 times for 3~15 times of " water environment quality standard " (GB3838-2002)；Total nitrogen is
15 times), there is larger gap between the two, direct emission can bring a series of problems.Municipal sewage plant's tail water water is big,
Organic concentration is lower and complicated component, and nitrogen and phosphorus content is higher, and advanced treating is carried out to it with certain difficulty.
Artificial Wetland Techniques are the ecosystems by manually building and controlling operation, by the controlledly dosing of sewage, sludge
Onto the wetland through manually building, sewage and sludge utilize soil, artificial dielectric, plant during flowing in a certain direction
The triple synergistic effects of object, the physics of microorganism, chemistry, biology absorb the polluters such as organic matter, nitrogen, phosphorus in sewage.Manually
The features such as wetland technology, which handles tail water, has investment maintenance cost lower, and secondary pollution is small meets the need of modern water process development
It asks.But single artificial wetland treatment is inefficient, treatment effect is unstable, is affected by temperature larger.Tail water pollutant
Content of organics is less, and microorganism vegetative activity is needed using carbon source, thus artificial swamp as tail water processing unit often
Ability can not be processed to bring into play completely.
Application No. is 201510680367.7 Chinese invention patents to disclose a kind of compound gravel bed of artificial swamp, the hair
Bright compound gravel bed is made of growth substrate layer and packing layer, is higher than 50% to COD removal rate, the removal rate of total nitrogen total phosphorus is also equal
60% or more, but when intake hydraulic loading, impact load are larger, single compound gravel bed is just unable to satisfy water outlet water
Matter requirement.
Application No. is 201610419636.9 Chinese invention patents to disclose a kind of intensified denitrification and dephosphorization combined type artificial
Undercurrent wetland processing system, the invention remove the suspended contaminant in sewage by sieve, are inhaled using microorganism, plant, matrix
Attached effect denitrogenation dephosphorizing, but when the organic matter deficiency of wastewater influent, it is difficult to denitrification denitrogenation is carried out, effluent quality is caused to be disliked
Change.
Therefore, in view of the deficiencies of the prior art, a kind of pretreatment of collection tail water is developed, combination type wetland denitrification dephosphorization system is
It is integrated, energy-saving, combined with landscape, current tail water processing requirement can be reached, be able to satisfy the following tail water process demand again
Wet land treating system.
