The utility model content
To the deficiency that exists in the above-mentioned prior art; The utility model aims to provide a kind of reduced investment, instant effect, energy consumption is low, effluent quality good, surplus sludge volume is few, but water outlet reuse, floor space are little, the eurytropy film mud symbiosis A/O system handles of economic operating cost, convenient management is dirty, the device of waste water.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is:
A kind of eurytropy film mud symbiosis A/O system handles is dirty, the device of waste water, comprises hydrolysis acidification pool and after-treatment system, and this device is connected to form by hydrolysis acidification pool, continuous cyclic oxidation pond, kneader type oxidation pond and after-treatment system successively.
Described hydrolysis acidification pool comprises preliminary sedimentation tank, aerating system and combined stuffing; Wherein preliminary sedimentation tank is located at the afterbody of hydrolysis acidification pool; The preliminary sedimentation tank bottom is provided with the awl bucket shape and sinks to the bottom, and aerating system is arranged on the hydrolysis acidification pool bottom, and combined stuffing is arranged on the top of aerating system.
Described continuous cyclic oxidation pond comprises eddy flow shearing bubble aeration device, arc training wall and midfeather; Wherein eddy flow is sheared the bubble aeration device and is located at the bottom, pond; The arc training wall is located at two ends in the pond; Midfeather is located between the two arc training walls, and all there are the gap between any two in arc training wall, midfeather and pool wall.
Described kneader type oxidation pond comprises eddy flow shearing bubble aeration device, elastic corrugated 3-D filler and gallery partition wall; Wherein eddy flow is sheared the bubble aeration device and is located at the pond inner bottom part; Elastic corrugated 3-D filler is located at eddy flow and shears bubble aeration device top, and the gallery partition wall is crisscross arranged in the pond.
Said after-treatment system is connected to form by medium sediment pool, second pond, rapid filter and sterilization and discharging pond successively.
Do further explanation and explanation in the face of the utility model down:
1, hydrolysis acidification pool (A)
Hydrolysis acidification pool is made up of acidication district and preliminary sedimentation tank.Acidication district current adopt the upper and lower pulling flow type that seethes.Aerating system and combined stuffing are set in the pond.
After the dirt of hydrolysis acidification pool Central Plains, waste water get into reactor drum; Through filler at the anoxic Sludge Bed acidification reaction that is hydrolyzed; Under a large amount of hydrolysis bacterium effects, insoluble hydrolysis of organic matter is become dissolved matter; Simultaneously under the synergy of acid-producing bacteria, with macromolecular substance, be difficult to degradable chemical and be converted into and be easy to biodegradable small-molecule substance, follow-up aerobe processing efficiency is greatly improved.
The ecological condition difference of two types of different strains in hydrolysising condition and the anaerobic technique is very big, and hydrolysis process is reaction under anoxia condition, and anaerobic technique then is under anaerobic to react. and said here " anoxic " is different from " anaerobism ".So-called anaerobism effect is meant absolute anaerobic (dissolved oxygen Do=O), and anoxia functions is meant little oxygen (Do＜0.5～1.5mg/L), promptly two kinds of mikrobe life conditions are different.
2, continuous cyclic oxidation pond (O
1)
Whole process is provided with eddy flow and shears the bubble aeration device in the cyclic oxidation pond continuously, adopts activated sludge process.It is simple that activated sludge process has equipment, and the water treatment degree is high, advantages such as less investment.
In design, kept the extended aeration of conventional oxidation ditch, current are circulation continuously, but round trip is shorter, has complete mixed characteristic.Operating load suitably improves.More function is to remove BOD
5With minimizing mud.On equipment, abandon commentaries on classics brush commonly used, changeed equipment such as butterfly, the surface aerating machine of falling the umbrella shape, adopted the high aerator oxygenation of dynamicefficiency.
The impact of the water-fast amount in cyclic oxidation pond, water quality continuously, the diffusion of oxygen and matrix and the full contact of mikrobe thereof, various reactions are balanced, and treatment effect is good.
3, kneader type oxidation pond (O
2)
Be provided with eddy flow in the kneader type oxidation pond and shear bubble aeration device and elastic corrugated 3-D filler, current are pulling flow type, adopt biomembrance process.
(food with mikrobe ratio) is very low because F/M in the pond, and the microbial nutrition condition is poor, so employing, helps the raising of living weight to be adsorbed as main biomembrance process and stablizes.In addition; When elastic corrugated 3-D filler and eddy flow shearing bubble aeration device are used; The strand of elastic corrugated 3-D filler has certain adsorptive power to the micro-bubble in the water, makes numerous micro-bubbles attached to around the elasticity strand, has prolonged the duration of contact of air water greatly; Moreover the elasticity strand of in water, evenly unfolding carries out multi-level cutting continuously to the bubble in the water, has reduced the diameter of bubble, has increased the contact area of bubble and water, thereby has quickened the transfer rate of oxygen, has improved the utilization ratio of oxygen.
In order to make the aerobic hard-degraded substance of part produce metamorphosis, improve BOD through acidication
5/ COD
Cr, the F/M value, dirty, waste water are carried out rubbing and eluriating repeatedly, fully screening, optimize and activate biological group, to improve treatment effect.
Compared with prior art, the advantage of the utility model is:
1, the device of a kind of eurytropy film mud symbiosis A/O system handles dirt, waste water adopts hydrolysis acidification pool (A), continuous cyclic oxidation pond (O
1) and kneader type oxidation pond (O
2) syllogic is dirty, wastewater treatment equipment; Be to utilize three sections varying environments to make the mikrobe natural variation that suspends and adhere to; Through competing naturally in three sections formation advantage separately; Strengthening biological activity to greatest extent and to increase living weight, synergy, thus reach the purpose of handling hard-degraded substance in dirty, the waste water.As required, each unit construction of the utility model can add and subtract, move that can go here and there can be also, and water outlet can reach the reuse water standard.Compare with dirt, the wastewater treatment equipment of equal scale, can reduce investment outlay about 30%, energy-conservation about 35%, excess sludge can reduce over half, and volume is also corresponding to be dwindled, and its economic benefit and social benefit are obvious.
2, behind former dirt, the said device acidication of waste water process the utility model; Utilize hydrolysis, the active strong and strong characteristics of adaptive faculty of acid-producing bacteria; Is the solubility small molecules with the macromolecular structure of difficult degradation in dirt, the waste water through hydrolysis, acidifying, to improve dirt, waste water BOD
5/ COD
CrRatio, be follow-up aerobic treatment, improve COD
CrClearance is laid a solid foundation.And make full use of the advantage of acidication, aerobic two kinds of treatment process, and make mud in flow process inner circulating reflux digest and decompose, make every effort to accomplish sewage, the disposable processing of mud, there is not secondary pollution.
