Description
Technical field
It is dirty more particularly to a kind of crop type artificial swamp the present invention relates in the technical field of environmental project sewage treatment
Water treatment facilities.
Background technique
Artificial swamp is a kind of sewage treatment ecological engineering technology to grow up the 1970s, since it has
The advantages that construction investment and operational management are low in cost, low energy consumption, the cycle of operation is long and operational effect stablizes and gradually answered
Sanitary sewage disposal for vast Small Urban and grass roots.
Artificial swamp combines three kinds of effects of physics, chemistry and biology to the processing of waste water.After wet land system is mature, fill out
Material surface and root system of plant will form deep biomembrane due to the growth of a large amount of microorganisms.When waste water flows through biomembrane, largely
SS stops retention by filler and root system of plant, and organic pollutant is then removed by the absorption of biomembrane, assimilation and dissimilation.
The transmitting of oxygen is discharged because of root system of plant in wet land system, makes occur aerobic, anoxic, the state of anaerobism in surrounding environment,
It ensure that the nitrogen phosphorus in waste water can not only be by plant and microorganism as nutrient absorption, but also digestion, anti-nitre can be passed through
The dissimilation such as change remove it.Wherein vertical current constructed wetland be considered as sewage nitrification reliable system purification efficiency compared with
Height, occupied area is smaller, has been widely used.
For most artificial wetlands, all consist of the following components: wetland plant, microorganism, filler etc..Plant
It is wetland bed in the presence of that can stablize, good condition is provided for physical filtering various pollutants, while also providing for the growth of microorganism
Good environment.The presence of a large amount of plants slows down flow velocity of the sewage in wetland, is conducive to the sedimentation of suspended particulate contaminants,
And reduces the erosion to system earth's surface and precipitate the settling flux of suspended matter.Due to the presence of root system of plant, the shape in matrix
At the gap of very little, the gas porosity of matrix is increased, hydraulic conductivity power (infiltration coefficient) of the sewage in matrix is made to be strengthened.
For the northern area of winter cold, the very important effect of one of plant is to prevent artificial wet land system
It freezes, while dead plant of standing upright plays insulating layer use with Winter Snow, to prevent artificial wet land system to pollutant
Removal ability be greatly lowered.
Wet land system requires water plant to have certain ability to bear to the pollutant of various high concentrations.Different growth rings
Border, suitable wetland plant are different.Surface current artificial wetland should select resistance to deep water plant；Undercurrent is because there is filling out for matrix
It fills, the terrestrial class plant with dense or longer root system should be selected.
In recent years, the economic utilization of wetland plant oneself be increasingly taken seriously.Wetland plant can be used as biomass
The energy is cultivated, and can be used as medicinal material, be can also be used as edible vegetable to cultivate, is also used as landscape plant to train
It supports, some economic benefits can be brought.Xiong Ying's etc. research shows that Lythrum salicaria, Scirpus tabernaemontani not only although effect is good, but also have
Certain economic value；Pollen, leaf, the stem of cattail all have economic value.Eutrophy is handled to water harmony dish and Chinese celery by literary brightness etc.
Change water body studies have shown that while guaranteeing that good denitrogenation removes the effect sympathized with, the stem and leaf part of the plant of harvest is also brought
Certain income.
Summary of the invention
The invention mainly solves the technical problem of providing a kind of crop type artificial wet field facilities for treating sewage, using uplink
Pond+downstream tank structure type complex vertical undercurrent constructs wetland, facilitates management, by matrix to COD and nitrogen removal effect
Preferably, while using crops with wetland plant it combines, it can more one progress guarantor to the biggish agricultural economy type crop of biomass
Card has preferable Nitrogen/Phosphorus Removal, and about 80% or so pollutant is removed by drowned flow artificial wet land, can improve the place of wetland
Efficiency is managed, makes wetland landscape, and agricultural production can be improved.
