Description

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

Technical field

The present invention relates to technical field of sewage.

Background technology

Currently, with the raising of urbanization and living standards of the people, a large amount of dispersion type domestic wastewaters are (such as:Samll cities and towns, high speed High road service area etc.), arbitrarily discharge results in serious water environment pollution and ecological environment after unprocessed or inappropriate processing Deteriorate.The characteristics of being polluted in conjunction with dispersing type and the actual conditions such as the villages and small towns level of economic development, select it is simple for process, low-cost, The water technology to work well is the key that solve current contamination.Artificial swamp have invest small, energy consumption and operating cost it is low, The advantages that applied widely, has become the important technology of distributed sewage pollution prevention.

However, the artificial swamp in most of areas is mainly based on current wetland (horizontal drowned flow or vertical subsurface flow), generally There is a problem of denitrification effect difference.Main path of the nitrification/denitrification process as wetland Microbial denitrogenation, wherein nitrifying process As the limiting factor of denitrogenation.For the problem that nitrifying process is limited, artificial aeration appropriate can effectively facilitate the progress of nitrification. But continuous aeration is of high cost, cannot generate aerobic/anaerobic alternate environment needed for denitrogenation, and intermittent aerating then can be by good Oxygen/anaerobic environment is converted to strengthen the removal of nitrogen.For high intensity waste water, intermittent aerating is only capable of playing nitrification.Together When, denitrification process also needs to supplement enough carbon sources, regulates and controls C/N ratios generally by additional carbon to realize efficient denitrification Process, but cost is excessively high.

The prior art is retrieved, CN102992500A discloses a kind of vertical current constructed wetland bottom aeration oxygen replenishing side Method by improving the dissolved oxygen content in water in wetland stratum aeration oxygen replenishing, and then realizes high efficiency nitrification process. CN105110551A discloses a kind of high dissolved oxygen aeration in conjunction with the sewage disposal system and treatment process of artificial swamp, passes through separation Aerating system and wet land system combination realize high efficiency nitrification process.CN102260021A discloses a kind of without additional carbon Domestic sewage advanced denitrification process and device, by it is micro- aeration vertical subsurface flow wetland and horizontal subsurface flow wetland group technology come Whole process autotrophic denitrification (aerobic/anaerobic ammoxidation) process of realization.In addition, Chinese patent notification number CN103043786A discloses one Plant the slow carbon source releasing media filter device and process with advanced nitrogen function, CN102826649A discloses a kind of utilize and is sustained Solid carbon source carries out the method for biological denitrificaion, CN103253772A discloses a kind of horizontal drowned flow artificial wet land solid carbon source reinforcing Denitrification system, these slow release carbon source systems show preferable Denitrification Characteristics.The above research is folk prescription surface strengthening nitre Change or denitrification process, and pass through combining form and realize efficient denitrification process.But how to be realized in same wet land system Nitrification/denitrification process is still a challenge, currently, being aerated and adding sustained release using micro- still without inside same wet land system Carbon source (without controlling carbon-nitrogen ratio, at low cost) realizes aerobic/anaerobic alternately and denitrifying carbon source strengthens the phase of pollutant removal Close report.
