Description
Technical field
This utility model relates to sewage or waste water process field, is specifically related to a kind of pond of oozing soon for CRI system and controls oxygen
Experimental provision.
Background technology
1, (Constructed rapid infiltration system is called for short: CRI) be land treatment systems CRI system
One type, it refer to control sewage is invested in manually construct ooze in pond soon so that it is under gravity by upper
Infiltration under and, makes sewage reach the process into water by each physics, chemistry and biological agent simultaneously.
2, short-cut nitrification and denitrification technique refers to control at Nitrification Stage by ammonium oxidation, then carries out denitrification work
With, eliminate in traditional biological denitrogenation and become nitrate to be then reduced into two links of nitrite by nitrite-oxidizing.Compare
More traditional biological denitrification process, this technology has the biggest advantage in actual motion technical process: 1, save the oxygen confession of 25%
Ying Liang, reduces energy consumption；2, reduce by 40% carbon source, in the case of entering organic matter of water concentration is relatively low, realizes denitrification denitrogenation；3, accelerate
The reaction mechanism mechanism of reaction, saves the denitrification pool volume of 50%；The enrichment that it is critical only that ammonia oxidation bacteria (AOB) of short-cut nitrification technology and Asia
Eliminating of nitrate oxidation bacteria (NOB), the mark that this technique realizes is that reactor has stable and higher nitrite accumulation rate
(NAR).Affect the primary outer of nitrous acid because have temperature, pH value, influent ammonia nitrogen loading, dissolved oxygen concentration etc..Utilize AOB and
Two kinds of strains of NOB are different to the affinity of dissolved oxygen, control reactor and are in low DO concentration, thus Selective depression NOB
It it is relatively common method.
3, Patent No. ZL200410073951.8, the invention of entitled " artificial rapid diafiltration sewage treating system device " is special
Profit, discloses a kind of CRI system, and it is by grid pond, preliminary sedimentation tank and oozes pond soon and forms, and is filled with human configuration in oozing pond the soonest
Artificial filtering material, generally natural river sand, Dali stone sand and limestone sand etc. combine in proportion.
4, Patent No. zl2008200642261.8, the practicality of entitled " a kind of artificial rapid infiltration sewage treatment equipment "
New patent, discloses a kind of artificial rapid infiltration sewage treatment equipment, and it is by water feed apparatus, ooze percolating device and water outlet dress soon
Put composition.This utility model have method technique flexibly, the advantage such as reduced investment, power consumption be few.
5, the CRI system of technique scheme all has a high treating effect, builds and operation cost is low, and it is excellent that energy consumption is low etc.
Point, but owing to current CRI system is due to denitrification section anaerobic environment and the shortage of carbon source, there is also nitrogen removal rate low
Shortcoming, constrains the promotion and application of CRI system.
Summary of the invention
The purpose of this utility model is the problems referred to above overcoming existing CRI system to exist, it is provided that a kind of CRI system is fast
Oozing the control oxygen experimental provision in pond, it controls to ooze air capacity in pond soon thus reduces the air capacity arriving denitrification section, controls simultaneously
In oozing pond soon, air capacity reaches to promote the growth of nitrite bacteria on biomembrane, limits the purpose of the growth of nitrobacteria, from
And the realization of short-cut nitrification and denitrification in making to ooze soon pond.
2, in order to solve the problem existing for background technology, this utility model is by the following technical solutions: it comprises people
Work oozes 2 two parts in pond 1 and U-shaped control oxygen pond soon: manpower rapid-infiltration pond 1 needs to seal, and only need to reserve an air inlet and connect U-shaped control
Oxygen pond and a water inlet and an outlet.Wherein outlet connects check-valves, prevents extraneous air from being entered by outlet
Enter and ooze pond soon and reduce increase pond internal gas pressure.
3, described U-shaped control oxygen pond 2, is connected by methacrylate sheet and makes, using water as backwash liquid, when sewage enters fast
When oozing pond, being pressed in U-shaped control oxygen pond by the air oozed soon in pond, in pond, the water in left side is pressed into right side, when the water in left side lands
During to bottom connected entrance, air is exhausted from system outside.In like manner, its exterior is discharged when sewage by oozing outlet bottom pond soon
Time, the water on the right side of U-shaped control oxygen pond under atmospheric pressure, diffluence to the left, when the water on right side drops to bottom connected entrance,
Extraneous air could enter and ooze soon in pond.Control ooze soon the air capacity in pond then can by U-shaped control oxygen pool inner water amount number come
Determine.
4, this detailed description of the invention controls the air capacity in manpower rapid-infiltration pond by controlling the water yield in U-shaped control oxygen pond,
Control to ooze air capacity in pond soon thus reduce the air capacity arriving denitrification section, control air capacity in oozing pond soon simultaneously and reach to promote
Enter the growth of nitrite bacteria on biomembrane, limit the purpose of the growth of nitrobacteria, so that ooze short distance nitration in pond soon
Denitrifying realization.
Whole control oxide structure composition is simple, easy and simple to handle.Raising for CRI system nitrogen removal rate provides a simplicity
And the method for practicality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
Detailed description of the invention:
1, the purpose of this utility model is the problems referred to above overcoming existing CRI system to exist, it is provided that a kind of CRI system
