Description
Technical field
The present invention relates to advanced treatment of wastewater and resource technology field, especially a kind of aquaculture water process and cycle
Utilize device and processing method.
Background technology
Industrial aquaculture is the important way of Modern Fishery cultivation.It is large-scale industrialized cultivate the water environment pollution that brings with
The problems such as aquatic products disease takes place frequently seriously annoyings the development of China's culture fishery.At present, industrial aquaculture major way is thick
The aquaculture model of type " water intaking-cultivation-in line " is put, extensive extensive style industrial aquaculture leads to water environment pollution and aquatic products disease
It takes place frequently.To find out its cause, being that the offshore pollution of getting worse causes sea-farming greatly to threaten and endanger, batch production is caused
Cultivating water source processing cost increases, meanwhile, a large amount of influences discharged to seawater fishery water area water-quality of breeding wastewater are very big.This
Outside, the industrial aquaculture base using saline groundwater resource as water source needs a large amount of groundwater abstractions, and seawater is caused further to be invaded
Underground reservoir, high saliferous cultivation Tail water reuse enters coastal soil can bring new salinity again, accelerate the soil salinization into
Journey.As a kind of technology-intensive industrial aquaculture pattern, circulating water culture system has cultivation density height, breeding environment can
Control, the advantages such as ecological environment destruction is small, aquaculture organism length speed is fast, can both reduce Tail water reuse, protect Offshore Ecology environment, again
The aquatic products of high yield and high quality can be obtained.Therefore, aquaculture system is handled and circulating and recovering is aquaculture field
A prior development direction.Circulating water cultivation is the inevitable choice of China's continental rise sea-farming sustainable development, still, at present
Technology for aquaculture system water process circulating and recovering is less, and processing cost is higher, and general to nitrogen removal effect, pole
The earth limits the popularization and application of circulating water cultivation technology.Therefore, cheap, the easy to operate aquaculture water process of development cost
And recycle utilization is of great significance and actual application value.
Deep-bed filter system has and takes up an area compared with the sewerage advanced treatment process such as membrane bioreactor, biological fluidized bed
The advantages such as area is small, operational mode is adjustable, construction cost and operating cost are low, to low concentration pollutant in water body especially tail water
Removal effect it is apparent.By carrying out literature search discovery, Wang Qing etc. " using deep-bed filter to Donggang City's sewage to the prior art
Plant effluent advanced nitrogen processing " mention in a text using deep-bed filter treated sewage processing plant tail water (《Treatment of Industrial Water》,
2014,28(11):66-68)；It opens sound etc. and mentions deep bed filter in " organic matter in activated carbon floating filter removal algae concentrated feeding water " text
Pond can be used for processing source water (《Chinese water supply and drainage》,2004,20(5):47-49).Deep-bed filter pond body is deeper, and filtrate is laid with
Thickness be more than 1.8 meters, in special circumstances, deep-bed filter filtrate thickness be up to 4 meters it is even more, therefore, when deep-bed filter application
In the poor sewage treatment plant of geological conditions, the problems such as deep basal pit is difficult in maintenance may be generated, construction investment is far above general
Logical filter tank, this shortcoming limit extensive use of the deep-bed filter technology in water treatment field.There has been no deep-bed filter skills at present
Art is for aquaculture water process and the report recycled.
Invention content
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to a kind of aquaculture water process is provided and recycles dress
It puts and processing method.
To achieve the above object, the present invention use technical solution for：
A kind of aquaculture water process and recycling device, device includes baffling deep-bed filter system and tomography seepage flow is answered
Oxygen nitriary, the water outlet of baffling deep-bed filter system are connected by pipeline with tomography seepage flow reoxygenation nitriary water inlet, baffling
Deep-bed filter system is made of at least one independent baffling deep-bed filter, baffling deep-bed filter system both sides sustained height difference
Equipped with inlet and outlet.
The baffling deep-bed filter system is sequentially connected in series connection for multiple independent baffling deep-bed filters by pipeline, is formed
Tandem type multi-stage baffling deep-bed filter system, each independent baffling deep-bed filter interpolation are baffled；
Or, the baffling deep-bed filter system is by an independent baffling deep-bed filter, and in plugging multiple baffles in pond,
Form iris type Multi-level deflector deep-bed filter system.
Between the baffle and the pool wall of the baffling deep-bed filter that are plugged in the baffling deep-bed filter system or baffle and baffle
Between form water-flowing path, and each water-flowing path is sequentially communicated, the wherein first water-flowing path of baffling deep-bed filter system and end
Water-flowing path is open top end, remaining water-flowing path top closure；Two kinds construct the mode baffled both sides flow direction of institute on the contrary,
So as to form baffling.
Modified filter material is laid in each filter tank of baffling deep-bed filter system；Wherein, tandem type multi-stage baffling deep-bed filter system,
Each independent baffling deep-bed filter is as level-one, and per level-one, the interior modified filter material that is laid with may be the same or different.
Bed body stent is equipped in the tomography seepage flow reoxygenation nitriary, topmost branch is provided with more than one water clock to bed body
Pipe is laid with modified filter material on remaining stent respectively, and then air tomography natural reaeration region and filtrate filling between filtrate is staggeredly divided into ooze
Flow denitrification area；Every layer of modified filter material laying depth is 5~10cm, and each layer is between the upper and lower away from for 5~10cm.The bed with it is upper
It is identical to swim baffling deep-bed filter.
The modified filter material mixes film liquid for chitosan-starch-acetic acid and is formed coated on filter material surface；Wherein mix
Film liquid is dissolved chitosan, water soluble starch powder by 1%~5% glacial acetic acid solution, and mixing polyethylene glycol is prepared, shell
Glycan, starch and Polyethylene glycol are 1%~5%.
The particle diameter of filter medium is 2~40mm, is common filter material for water treatment, such as fluid bed filtrate, haydite, fibrous nodules filter
Material, granular activated carbon, gravel, cobblestone etc..
