Description
Technical field
The present invention relates to technical field of sewage, and in particular to a kind of using agricultural biomass discarded object as slow release carbon source
Horizontal drowned flow baffling artificial wet land system.
Background technology
At present, traditional sewage treatment process turns into the major technique of the urban sewage treatment of China's overwhelming majority, for
Control Urban Water Environment pollution serves certain effect, but due to being limited to the rural areas in our country level of economic development, Yi Jineng
Source shortage, pollution sources disperse, and the low present situation of operational administrative technical staff's level, and sewage treatment project is in rural area and small city
Promote and encounter huge resistance in town；Traditional waste water treatment process has the excessive, cost of water treatment of investment too high simultaneously, manages skill
The grasp of art is strict for peopleware and educational level requirement, thus is also not appropriate for the actual conditions of rural areas in our country,
Directly discharge will cause water environment pollution.Artificial swamp eco-treatment technology has small investment, energy consumption and operating cost low, suitable
With scope it is wide the advantages of, be a kind of simple and effective ecological engineering sewage disposal technology, be especially suitable for, especially exist with China's national situation
Vast rural area, Small Urban are administered for dispersion type domestic wastewater, with wide application and development prospect.
Artificial swamp ecological control techniques mainly pass through one between polluted water body and wetland plant, matrix and microorganism
Serial complicated physics, chemistry and biochemical action, including physics chemical action is such as precipitated, filtered, adsorbing, ion exchange, with
And the absorption of biological agent such as plant and microorganism, decomposition, conversion number of ways are realized to various pollutions in polluted water body
The purification of the thing such as polluter such as suspension, organic matter, metal ion, nutrient, hardly degraded organic substance and pathogen.So
And, the removal of nitrogen mainly acts on jointly completing by the Autotrophic nitrification and heterotrophic denitrification of microorganism, nitration denitrification mistake
Journey is completed generally by the combination of vertical-flow wetland nitrifying process and horizontal-flow wetland denitrification process, how same anti-
The research for realizing denitrification process in device is answered still to compare shortcoming；In addition, on low C/N than decentralized sewage carbon source deficiency turned into
The limiting factor of denitrogenation, though at present by liquid carbon source (such as：Methanol etc.) and solid carbon source (thermoplastic biologically degradable gather
Ester) carry out intensified anti-nitrated process, effect plays a role but cost is too high.Therefore, according to the treatment of wastes with processes of wastes against one another, the original of ecological regulation and control
Then, using the recycling of rural area biomass waste as target, by waste wood head, rice straw, maize straw, corn ear or litter etc.
Discarded object by aerobic/anaerobic, has carbon/Wetland ecological regulation and control that are carbon-free, having alkali/alkali-free principle same to realize as filler
The efficient removal of carbon/nitrogen has stronger scientific meaning and real value in system.
The content of the invention
The synchronization that carbon/nitrogen is realized in same system the invention aims to solve Traditional Man wet land system to be difficult to
Efficiently remove, the problem of COD, ammonia nitrogen and nitrate nitrogen clearance are relatively low, and a kind of artificial wet land reinforced carbon of ecological regulation and control type is provided
Nitrogen synchronously removes system.
The artificial wet land reinforced carbon nitrogen of ecological regulation and control type of the present invention, which synchronously removes system, includes cistern, water distribution area, wetland one
Level packing area, two grades of packing areas of wetland, wetland three-level packing area, the upper strata area of coverage and gathering ground, flow through direction along water and set successively
Putting the matrix filled in wetland one-level packing area, two grades of packing areas of wetland and wetland three-level packing area, wetland one-level packing area is
The matrix filled in slow release carbon source or clinker, two grades of packing areas of wetland is slow release carbon source or clinker, and wetland three-level is filled out in packing area
The matrix filled is gravel or clinker, and wetland one-level packing area, two grades of packing areas of wetland, wetland three-level pass through next door between packing area
Separate, the water hole being provided with next door on water hole, adjacent partitioning walls has difference in height, in wetland one-level packing area, wetland two
The top of level packing area and wetland three-level packing area is the upper strata area of coverage, and the matrix of upper strata area of coverage filling is gravel, on upper strata
Planted on the area of coverage and be implanted with plant, the both sides of the upper strata area of coverage are respectively water distribution area and gathering ground, and cistern passes through water inlet pipe and cloth
Pool is communicated, and the delivery port being provided with water inlet pipe in peristaltic pump, gathering ground is communicated with delivery pipe.
The artificial wet land reinforced carbon nitrogen of ecological regulation and control type of the present invention synchronously removes system, and in addition to cistern, remaining region is equal
Inside wet land system, the water inlet pipe and outlet pipe are located at system both sides, and the waste water in cistern is by peristaltic pump from system
Water inlet pipe be pumped into, waste water passes sequentially through both horizontally and vertically operation and eventually arrives at floss hole, during this, successively by having
Oxygen/anaerobic, there is carbon/carbon-free, have alkali/alkali-free region, by strengthening synchronization of the nitrification/denitrification process to realize carbon and nitrogen
Remove.
Waste water in the synchronous removal system of heretofore described artificial wet land reinforced carbon nitrogen passes through level stream and vertical current
Mixed running pattern, effectively extends the time of contact of substrate and matrix, the removal of reinforcing carbon and nitrogen.Wherein slow release carbon source is anti-
Nitrification provides sufficient carbon source, and clinker/gravel provides abundant basicity for nitrification, and gravel is then as the whole processing unit of whole device
Point；Meanwhile, by exchanging for one-level packing area and two grades of packing area fillers, nitrification/denitrifying functional mapping can be achieved, effectively
Strengthen the removal of nitrogen.
The artificial wet land reinforced carbon nitrogen of the present invention, which synchronously removes system, includes advantages below：
