Technical field
The present invention relates to a kind of rice waterborne for cultivating tail water regeneration to make method；Belong to cultivating wastewater purification and recycles skill
Art field.
Background technique
Artificial swamp as a kind of ecological water treatment technology, sewage treatment, in terms of be used widely.
Some researches show that (Sun Wenzhang, 2014), right using increase Wetland Substrate dissolved oxygen content when hydraulic loading is 0.33m/d
It is 84%, 69% and 68% that COD, TAN, TP, which have highest removal rate,；To biogas slurry waste water is come from, when hydraulic loading is 0.1m/d, manually
Wetland is maximum to COD, TAN, TP removal rate, respectively 90%, 85%, 98%(Li Meiling, 2014), ordinary circumstance constructed wetlands
Best hydraulic loading is at 0.5m/d or less (He Liping, 2014), however polluted surface water, domestic sewage in rural areas etc. often have
N, therefore the features such as pollutant concentrations such as P are low, and water is big is taken up a large area using the presence of artificial wetland treatment breeding wastewater
It is insufficient.
In Constructed Wetland for Wastewater Treatment, plant action can be summarized as three aspects: 1) dirt is directly absorbed and utilized
Using the nutriment of state, absorption and enriching heavy metal and some poisonous and harmful substances in water；It 2) is root zone aerobic microbiological
Convey oxygen；3) enhance and maintain the waterpower transmission of medium.The plant of artificial swamp seed selection at present is usually iris, calamus, again power
It spends, these plants are generally that biomass is big, aithullium of well developed root system, but that there are economic values is not high, to a certain extent
Artificial swamp is influenced to promote and apply.
Biological aerated filter BAF(Biological Aerated Filter) it is the one of America and Europe's the 1980s exploitation
Kind Novel sewage processing technique.It has used for reference the mentality of designing of sewage treatment contact oxidation method and water supply rapid filter, collection aeration, height
The features such as filtering velocity, retention suspended matter and periodically backwash,, land occupation high with load was less, low energy consumption, water outlet is good and technique in one
The advantages that simple and flexible, biological aerated filter have used for reference the design principle of biological contact oxidation reactor and deep-bed filtration unit,
Secondary precipitation pool equipment is eliminated, occupied area is greatly reduced, it is grown up on the basis of ordinary biofilter
A kind of sewage treatment technique, maximum feature are to integrate biological oxidation and retention suspended solid, save subsequent two
Secondary sedimentation basin ensure that good treatment effect, and simplify treatment process to the greatest extent.Biological aerated filter process is also
Has the features such as organic matter volumetric loading is high, hydraulic loading is big, hydraulic detention time is short.The filtrate of biological aerated filter generally closes
At materials such as fiber, polystyrene sphere, corrugated platings, in the process of running due to filter clogging, it is necessary to be restored by backwash
Water treatment performance, the backwash mode generallyd use are combined water and air backwashes, i.e., are first rushed with gas, then are combined with gas and water and rinsed,
Finally rinsed again with water, therefore, construction, the operation and maintenance of the aeration tank deficiency excessive there are expense.
Summary of the invention
It is an object of the invention to: in view of the above-mentioned problems existing in the prior art, provide a kind of cultivation tail water regeneration
Rice waterborne make method；This method can be promoted by control aeration intensity and hydraulic loading to aquaculture according to project situation
The low pollutions object concentration water body purification function such as waste water and the water process scale of construction, and by the plantation of industrial crops, realize higher warp
Benefit of helping and better environmental benefit.
The technical scheme is that
It is a kind of cultivate tail water regeneration rice waterborne make method；It is characterized in that, it the following steps are included:
1) rice waterborne, is made the breeding wastewater in the cultivating pool in system to be discharged into sump by culvert pipe through closed conduit,
To carry out coarse filtration and sedimentation；
2) waste water, through coarse filtration and sedimentation is promoted by inlet water lifting pumps, and the water inlet pipe of planting bed is flowed into through pipeline；And
Overflow enters wedge-shaped water distributing trough to carry out uniform water distribution to planting bed;
3), overflow enters planting bed waste water and filters again through water inlet end cobble filtering layer first, further to remove sump not
Filtrable solid particulate matter；
4) waste water, through water inlet end cobble filtering layer coarse filtration enters planting bed, and plantation bottom of pond portion is equipped with matrix, in matrix
Side is implanted with rice by haydite kickboard kind, and the coverage rate of haydite kickboard is controlled 50% ~ 70% in planting bed；By planting bottom of pond portion
The gap of matrix and the biomembrane in rice root zone haydite matrix gap, it is inorganic can be decomposed into small molecule for macromolecular itrogenous organic substance
Object is discharged into outer layer water body, and to promote plant absorption to act on, while flourishing rice root is to particulate matter remaining in waste water
Apparent retention can be played, to realize the purification again of waste water.
5), rice needs control filter tank hydraulic loading not less than 1.16 m in planting process before the rice striking root phase3/
(m2D), foliar fertilizer and in tillering stage, heading stage, blooming stage and pustulation period is sprayed, to guarantee that rice different growing stages nutrition needs
