Description

A kind of micro-aeration type solid carbon source wet land system and denitrification treatment process thereof with advanced nitrogen function

Technical field

The present invention relates to technical field of sewage.

Background technology

At present, along with the raising of urbanization and living standards of the people, a large amount of dispersion type domestic wastewaters (as: samll cities and towns, at a high speedHigh road service area etc.), unprocessed or inappropriate processing is arbitrarily discharged and has been caused serious water environment pollution and ecological environment afterwardsWorsen. The actual conditions such as feature and the villages and small towns level of economic development of polluting in conjunction with decentralized, selection technique is simple, expense is cheap,Respond well water technology is the key that solves current pollution. Artificial swamp has little, the energy consumption of investment and operating cost is low,The advantage such as applied widely, has become the important technology of decentralized sewage pollution control.

But the artificial swamp in most of areas mainly, is generally deposited as main taking current wetland (horizontal drowned flow or vertical subsurface flow)In the poor problem of denitrification effect. Nitrated/denitrification process is as the main path of wetland Microbial denitrogenation, wherein nitrifying processBecome the limiting factor of denitrogenation. For the limited problem of nitrifying process, suitable artificial aeration can effectively promote nitrated carrying out.But continuous aeration cost is high, can not produce the required aerobic/anaerobic alternate environment of denitrogenation, and intermittent aerating can pass throughThe conversion of oxygen/anaerobic environment is strengthened the removal of nitrogen. For high strength waste water, intermittent aerating only can play nitrification.Meanwhile, denitrification process also needs to supplement enough carbon sources, is generally to regulate and control C/N ratio by additional carbon to realize efficientlyDenitrification process, but high cost.

Prior art is retrieved, and CN102992500A discloses a kind of vertical current constructed wetland bottom aeration oxygen replenishing sideMethod, by improving the dissolved oxygen content in water at wetland stratum aeration oxygen replenishing, and then realizes high efficiency nitrification process.CN105110551A discloses sewage disposal system and the treatment process of a kind of high dissolved oxygen aeration in conjunction with artificial swamp, by dividingFrom aerating system and wet land system combine to realize high efficiency nitrification process. CN102260021A discloses a kind of without additionalDomestic sewage advanced denitrification process and the device of carbon source, by the combination work of micro-aeration vertical subsurface flow wetland and horizontal subsurface flow wetlandSkill realizes whole process autotrophic denitrification (aerobic/anaerobic ammoxidation) process. In addition Chinese patent notification number CN103043786A,A kind of slowly-releasing carbon source filter material filter pool device with advanced nitrogen function and technique are disclosed, CN102826649A discloses oneKind utilizes slow-release solid carbon source to carry out the method for biological denitrificaion, CN103253772A discloses a kind of horizontal drowned flow artificial wet landSolid carbon source strengthened denitrification system, these slowly-releasing Carbon Sources Systems have all shown good Denitrification Characteristics. More than research is allNitrated or the denitrification process of one-sided strengthening, and realize efficient denitrification process by combining form. But how same wetIn ground system, realize nitrated/denitrification process and be still a challenge, at present, still not micro-in the inner employing of same wet land systemAeration and add that slowly-releasing carbon source (carbon-nitrogen ratio, cost are low without controlling) realizes aerobic/anaerobic alternately and denitrifying carbon source is strongChange the relevant report of pollutant removal.
