The principle and the concrete mode that adopt a kind of multistage automatic oxygenation waste disposal plant of present embodiment to carry out sewage disposal are:
It is to have under the condition of dissolved oxygen, oxidation operation is resolved into CO that aerobe is handled
2And H
2O, and give off energy.This example design sewage load is 24t/d, according to the big natural condition of on-the-spot Sewage outlet drop, elder generation according to the mode that absolute altitude successively decreases, is divided into the little biochemistry pool 3 of 5 same structures with traditional aerobe chemical reaction pond, separates with special oxygenation chamber 2 between each little biochemistry pool 3.The your pupilization pool structure is of a size of 1.8m * 0.7m * 1.4m, and Dan Chichang is 2.57 with wide ratio (L/B), and aerobic biochemical pond cubic capacity is about 9m
3Oxygenation chamber agent structure is of a size of 2.0m * 0.1m * 2.0m, crosses the wide 40mm that is about of water space.About 300mm place, below, the indoor sidewall of oxygenation upper edge is provided with a suction opening 5, and its planar dimension is 1.0m * 0.5m.Oxygenation chamber 2 requires level to install, and every grade of oxygenation chamber 2 exceeds biochemistry pool 3 liquid level 0.6m.Biochemistry pool 3 peripheral pool walls and oxygenation baffle plate main body adopt Gang Zhu Obstinate structure.Water distributing pipe is installed at 2 inner side-walls about 200mm place at the bottom of the pond in oxygenation chamber, and water distributing pipe is selected steel pipe manufacturing for use.Be convenient maintenance, go out water distribution pipe and be connected, and report to the leadship after accomplishing a task respectively and lay out the water hole going out the downward 45 ° of directions in water distribution pipe both sides respectively by the distance of interval 300mm with oxygenation chamber 2 main bodys employing flange.Uniform distribution soft-filler 11 in the biochemistry pool, soft-filler 11 materials are selected Gao Chuo degree vinylon fibre for use.The two ends of every filler are separately fixed on the support that metal tube makes, and the filler upper end is apart from the about 200mm in underwater, the filler lower end apart from the pond at the bottom of about 250mm, filler according to arrange, line-spacing 80～120mm restraints and assembles apart from 60mm.Filler support 10 in each biochemistry pool 3 can whole load and unload filler volume 6.2m
3, account for 70% of pond appearance.Under the adapt circumstance condition, can cover with specific microorganism species on biochemistry pool 3 fillers, form microbial film.
For guaranteeing the water inlet of first step oxygenation chamber evenly, give full play to the effect of its oxygenation, a distribution reservoir 1 is set before first step oxygenation chamber, distribution reservoir 1 scantlings of the structure is 2.0m * 0.5m * 0.8m, the absolute altitude on the limit that distribution reservoir is adjacent with multistage automatic oxygenation biochemical treatment apparatus is a little less than other three limits, and distribution reservoir pond body is a Gang Jin Obstinate structure.
Sanitary sewage gravity flow after anaerobic biological is handled enters distribution reservoir 1, overflow enters the first step oxygenation chamber 2 in the automatic oxygenation biochemical treatment apparatus then, in entering the process of letting out for 2 times the oxygenation chamber, produce certain flow velocity, comprise the package action of current owing to produce little negative pressure in the process that oxygen level exists concentration difference and sewage to let out in sewage and the air under with certain flow velocity, all can promote airborne oxygen in sewage, to spread air.In the process of water inlet continuously, ambient air constantly enters automatically in the oxygenation chamber 2 along suction opening 5 and is fully absorbed by sewage.Sewage after the oxygenation enters biochemistry pool 3 bottoms through the person in charge 7 and the arm 8 of water distributing pipe.With flow through filler 10 in the biochemistry pool 3 of certain flow velocity, sewage and microbial film contact through the sewage of oxygenation, and under action of microorganisms, pollutants in sewage is decomposed by bio-oxidation, thereby sewage is purified.Sewage is about 2h in the residence time of one-level biochemistry pool, and the COD clearance is 20～30%; Dissolved oxygen rises to about 0.3mg/l in the sewage.3 water outlets of first step biochemistry pool are flow automatically once more and are entered oxygenation chamber, the second stage 2, and sewage repeats the technological process of upper level, and secondary biochemical pond 3 water outlet COD clearances can be increased to about 40%; Dissolved oxygen in the water will rise to about 0.6mg/l.Repeat above-mentioned technological process successively, sewage gravity flow enters next stage oxygenation chamber 2, along with the increase and the prolongation of sewage biochemical treatment time of the number of times of automatic oxygenation, and effectively biochemical time 8.8h, dissolved oxygen rises to more than the 1.5mg/l in the sewage; BOD volumetric loading 1.0～3.0kg/m
3.d; The COD clearance reaches more than 85%; BOD
5Clearance reaches more than 90%.
