Description
Technical field
The invention belongs to organic wastewater bioremediation Technology field, it is related to a kind of farm being effectively treated using periphyton
The method of waste water more particularly to a kind of method that nitrogen phosphorus in Pig raising wastewater is effectively treated using periphyton.
Background technique
With the development of livestock and poultry cultivation technology, distributing pig-breeding, which is gradating, produces mould for the live pig of scale
Formula, this large batch of concentration breeding way will necessarily generate the nutriments such as a large amount of rich Nitrogen-and Phosphorus-containings and the pig manure of microorganism is useless
Water.And the pig farm of this scale mainly build city in, near town, it is clear that receiving is carried out in not enough agricultural lands, and these are dirty
Water, if necessarily leading to the pollution and eutrophication of neighbouring lake and river water, so scale with regard to direct emission without processing
Change the concern that problem of environmental pollution caused by pig-breeding gradually causes everybody.
Periphyton, which refers to, is grown in the compound group that algae, bacterium and clast in water body in various stromal surfaces form
It falls, there is natural purification and filtration, it is made by absorption and sorption, oxygenolysis, precipitating and the storage to nitrogen and phosphorus
With the trophic level for having adjusted water body, it is both the main attemperator of primary producer and nutriment flowing, is water body richness
Nutrient laden is administered and important link irreplaceable in recovery process.Research finds that periphyton not only has the nitrogen phosphorus in waste water
There are good absorption and delay effect, but also there is good absorption and precipitation to the suspended particulate matter in water body,
It can be effectively reduced the trophic level of Water phosphorus, increase water transparency.Periphyton is successively applied to originally by people
Pretreatment, oxidation pond, sewage treatment plant and aquatic products recirculation system of aquatic production etc..
Chinese patent CN103663672A propose " feeding fish is scraped in a kind of utilization and periphyton jointly controls lake richness
The method of nutrient laden ", be using artificial substratum growth periphyton the nitrogen phosphorus in water body is effectively absorbed and is converted, and
Periphyton is the bait for scraping feeding fish, so putting a certain amount of Zhou Congsheng for scraping feeding fish, going to scrape in food matrix in a suitable place to breed again
Object, to achieve the purpose that reduce Water phosphorus nutrition material concentration and improve aquatic products amount.The technology is in control lake Fu Ying
Though certain effect is achieved in terms of feedingization, it is lower since the growth of periphyton needs enough illumination and nutritional condition
Trophic level or deeper nutrition-enriched water of lake in the biomass of periphyton be difficult to improve, so using feeding fish is scraped
The method for jointly controlling lake eutrophication with periphyton is difficult to realize, and directly promoting and applying there is also some problems.But mesh
It is preceding there is not yet using periphyton removal pig farm waste water in nitrogen phosphorus relevant report.
Summary of the invention
The present invention provides a kind of methods for effectively removing nitrogen phosphorus in cultivation factory's waste water using periphyton, purify scale
The excrement and urine water of a large amount of rich Nitrogen-and Phosphorus-containings generated during poultry or livestock breeding, purified water can be used for field irrigation, gardens
Greening etc., and treated that periphyton is easy to harvest, and can be used as fertilizer or feed, effectively realizes that the benign ecology of waste water is followed
Ring.
To achieve the above objectives, the present invention adopts the following technical scheme:
A method of animal farm wastewater is handled using periphyton, comprising the following steps: adheres to suitable periphyton
And the artificial substratum of easily folding and unfolding is put into natural eutrophication water, the periphyton in water body is seeded on artificial substratum；It will
Pretreated animal farm wastewater is discharged into outdoor annular processes pond, then that the artificial substratum for being attached with week from algae is uniform
It is put into annular processes pond, handles 8~12 days, the periphyton being seeded on nylon wire can be using sunlight, in farm
While growth in waste water, effectively remove the nitrogen phosphorus in waste water, animal farm wastewater after processing, wherein total nitrogen, total phosphorus and COD
Removal rate is respectively 86.5~94.8%, 93.4~98.7% and 91.5~95.6%.
Specifically includes the following steps: (1) adheres to suitable periphyton and the artificial substratum of easily folding and unfolding is put into natural rich battalion
At underwater 0.2~0.5m of feedingization lake littoral zone, after culture 8~15 days, the people that apposition growth there are a large amount of periphytons is fetched
Work matrix is stand-by；
(2) by animal farm wastewater after sedimentation basin staticly settles 4~8 hours, the waste water of preliminary sedimentation is moved into flocculation basin,
It is handled again with sewage flocculant, COD value is obtained after filter screen filtration in 500~800mgL-1Processing to be clean cultivation
Field waste water；
(3) pretreated animal farm wastewater in step (2) is discharged into outdoor annular processes pond；
(4) artificial substratum after being inoculated with will be completed to be put into vertically in annular processes pond, natural lighting is carried out daily, by 8
After processing in~12 days, the removal rate of total nitrogen, total phosphorus and COD is respectively 86.5~94.8%, 93.4~98.7% and in water body
91.5~95.6%；
(5) waste water after being disposed is carried out as field irrigation, water for afforestation using and being attached with week from algae
Artificial substratum after 2~3 batches of animal farm wastewaters that are disposed, be drawn off and collect thereon week from algae as agricultural fertilizer
Material or fishery cultivating feed carry out using.
The artificial substratum is granite block, PVC board, polythene net or nylon wire.
