Conducive to the removal of organic matter；
2, combined artificial wetland can ensure the high efficiency and stability of present treatment system, both can increase water body activity or can
Control water pollution；
3, disclosure process flow is simple, low energy consumption, save the cost.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of sewage disposal system based on anaerobism-AO- combined artificial wetland of the disclosure.
Specific embodiment
The technical solution of the disclosure is described in detail with reference to the accompanying drawings and examples.
As shown in Figure 1, the disclosure provides a kind of sewage disposal system based on anaerobism-AO- combined artificial wetland, comprising:
Anaerobic pond, anoxic pond, aerobic tank, sedimentation basin, ecological pond and artificial swamp；Wherein, the delivery outlet of the anaerobic pond is lacked with described
The input port in oxygen pond is connected；The delivery outlet of the anoxic pond is connected with the input port of the aerobic tank；The output of the aerobic tank
Mouth is connected with the input port of the sedimentation basin；The delivery outlet of the sedimentation basin is connected with the input port of the ecological pond；The life
The delivery outlet on the state pool is connected with the input port of the artificial swamp.
Above embodiments describe a kind of sewage disposal systems based on anaerobism-AO- combined artificial wetland, can effectively drop
Solve the nitrogen and phosphorus in the organic matter and removal sewage in sewage.
The specific implementation process of the present embodiment are as follows:
Sewage flows into anaerobic pond, while one of active carbon, mineral powder, flyash or lime stone are added in anaerobic pond
Or it is several, convenient for improving the stability of microorganism concn and system, be conducive to the removal of organic matter, by the anaerobism of certain time
It decomposes, removes part BOD, part nitrogenous compound is made to be converted to N2And it discharges, the poly- phosphorus Microbiological release phosphorus in returned sludge；
Then sewage flows into anoxic pond, and denitrifying bacteria is by the nitrate reduction come in aerobic tank by inner circulating reflux at N2；It connects
The sewage that gets off flows into aerobic tank, and ammonia nitrogen carries out nitrification and generates nitrate, and organic matter is degraded, and microorganism inhales phosphorus, through heavy
With rich phosphorus dirt discharge behind shallow lake, achieve the effect that dephosphorization；Bio-chemical effluent flows into combined artificial wetland, compound people after sedimentation tank filter
Work wetland is made of ecological pond and artificial swamp, utilizes plant, microorganism, the physics of artificial dielectric, chemistry, the triple collaborations of biology
Reaction, depth remove organic matter, nitrogen, phosphorus in water body.
In another embodiment, added in the anaerobic pond following any: active carbon, mineral powder, flyash and lime stone.
In the present embodiment, active carbon contains a large amount of micropores, have huge incomparable surface area, can be effectively removed coloration,
Stink can remove most organic pollutants and certain inorganic matters in sewage；The Al contained in flyash2O3, CaO isoreactivity group
Point, can produce complex with the fluorine in sewage or production have the colloidal ion of flocculation to fluorine, also containing zeolite, mullite,
Carbon granule and silica gel etc. have inorganic ions commutativity and adsorption and decoloration；Mineral powder has cellular structure feature, porosity
It is higher, it can not only suspended matter and organic matter in trap water, moreover it is possible to phosphorus in water body be fixed, there is dephosphorization function；Lime stone can
As pH adjusting agent, underwater gold category ion precipitation can be made, the impurity such as oil removal can be removed while removing underwater gold category ion, it
It itself is also equipped with chemical precipitation dephosphorization, has the function of Phosphate Sorption.
