Technical field
The present invention relates to field of waste water treatment, relate in particular to the biochemical processing method of a kind of testudinate wastewater of industrial cultivation.
Background technology
Along with progress and the expansion of the market demand of aquaculture technology level, China's industrialized aquiculture obtains in recent years
Develop rapidly, residual bait contained in breeding wastewater, chemical residues thing and rich in nitrogen, phosphorus, organic matter and toxicity
The aquaculture organism Excreta of material can aggravate to cultivate vicinity waters water body eutrophication degree and water pollution, the anti-mistake of water pollution
Restrict the development of aquaculture.Therefore, aquiculture waste water processes and recycles and gradually receives publicity.
Testudinate industrialized culture is the special cultivation industry that China is emerging, can the most constantly discharge cultivation give up in breeding process
Water, has containing substantial amounts of testudinate Excreta and food-residue, the mainly inorganic nutrient salt such as nitrogen, phosphorus and protein etc. in waste water
Machine thing, wherein ammonia nitrogen and COD concentration are the highest.The management mode using big row to change greatly of breeding water more, breeding wastewater
Handling rate is low, not only results in the eutrophication of surrounding water, and can heavy damage water source and ecological environment.Therefore, Testudinis
Trionyx sinensis Wiegmann cultivating wastewater purification technique is the most urgent.
At present breeding wastewater is mainly used group technology and the anaerobic methane fermentation skills such as ecological ditch, ecological canal and artificial swamp
Art.But, the efficient treatment technology for testudinate wastewater of industrial cultivation water quality characteristics lacks the most very much, universal existence and stability
Difference, poor operability, water quality is difficult to the problems such as qualified discharge, and industrial sewage treatment technology is invested greatly for plant,
Operating cost is high, is difficult to bear.
Summary of the invention
It is high that the technical problem to be solved is to provide a kind of stability, and operability is good, and energy-efficient, water outlet reaches
The biochemical processing method of the testudinate wastewater of industrial cultivation of integrated wastewater discharge standard primary standard.
In order to solve above-mentioned technical problem, the present invention adopts the following technical scheme that the biochemistry of a kind of testudinate wastewater of industrial cultivation
Processing method, comprises the following steps:
A, waste water is passed through in grille well carry out cut dirt process；
B, waste water after grille well processes are passed through in regulating reservoir and carry out equalizing the water yield and water treatment；
C, waste water after regulating reservoir processes are passed through in hydrolysis acidification pool and carry out acidification hydrolization process；
D, waste water after hydrolysis acidification pool processes are passed through in contact-oxidation pool and carry out aerobic resolution process；
E, waste water after contact-oxidation pool processes are passed through in sedimentation tank and carry out mud-water separation process, are purified water；
F, purification water is passed through in sterilization pool, after disinfecting.
Further, described waste water hydraulic detention time in grille well is 1h, and the hydraulic detention time in regulating reservoir is
2h, the hydraulic detention time in hydrolysis acidification pool is 6h, and the hydraulic detention time in contact-oxidation pool is 6h, heavy
Hydraulic detention time in pond, shallow lake is 15min, and purifying water hydraulic detention time in sterilization pool is 30min.
Further, being equipped with filler in described hydrolysis acidification pool and contact-oxidation pool, described filler is by support bar and uniform cloth
Putting the multiple filler body on support bar to constitute, described filler body includes plastic skeleton and fibre bundle, described plastic skeleton
Outer shroud, internal ring and the collar sequentially coaxially arranged including ecto-entad, between described outer shroud and internal ring, between internal ring and the collar
All being connected by reinforcement, described support bar is connected through the collar with filler body, and described fibre bundle has a plurality of and uniformly sets
Put on described outer shroud.
Further, described fibre bundle uses hydroformylation fiber or dacron thread to make.
Further, described filler first carried out biofilm process before waste water is passed through, and what biofilm processed concretely comprises the following steps:
(1) taking activated sludge from discharge of wastewater ditch, aeration cultivates domestication 2 days at room temperature；
(2) mix cultivating the activated sludge tamed with the ratio of waste water 1:5 by volume, add special bacterium solution,
Obtain mixed liquor；
Described special bacterium solution is 1:100 with the volume ratio of waste water, and in described special bacterium solution, bacillus subtilis viable count is
1×109～3 × 109Individual/ml, Bacillus licheniformis viable count is 1 × 109～3 × 109Individual/ml, Rhodopseudomonas palustris viable count
It is 2 × 105～1 × 105Individual/ml, Nitrosomonas viable count is 1 × 109～2 × 109Individual/ml, denitrification bacillus viable count is
1×109～2 × 109Individual/ml, streptococcus faecalis viable count is 1 × 109～5 × 109Individual/ml；
(3) with above-mentioned mixed liquor for biofilm raw material, biomembrane is formed by existing colonization method at filling surface.
Compared with the prior art, the present invention has the beneficial effect that:
1. the present invention uses the PROCESS FOR TREATMENT testudinate industrialized culture cutting dirt+hydrolysis acidification+catalytic oxidation+mud-water separation+sterilization to give up
Water, COD clearance reaches 90.9%, and SS clearance reaches 91.3%, N-NH3Clearance reaches 94.2%, and water outlet reaches sewage and combines
Close discharge standard (GB8978-1996) primary standard.
2. through the present invention process breeding wastewater can reuse, according to influent quality (being shown in Table 1), wherein COD presses 180mg/L
Calculate, N-NH3Calculate by 40mg/L, COD and N-NH can be cut down3Discharge capacity is respectively 19.7t/a and 4.4t/a, with
Shi Pingjun can reduce the fresh water usage amount of 300t every day, and therefore, environmental benefit of the present invention is preferable.
