Description
Technical field
The invention belongs to sewage treatment area, and in particular to a kind of to be oxygenated sewage-treating reactor and processing side without bubble film
Method.
Background technology
All there is Aerobic Pond in traditional life sewage treatment process, aeration energy consumption is excessive mostly, account for whole Sewage Disposal
More than 1/2, and aeration utilization rate is low, there was only 10%-20% to the utilization rate of oxygen, energy consumption is big, and oxygen is more to overflow the water surface, ease with bubble
Dissipate seriously, the utilization rate of oxygen is relatively low；Slough or short stream easily occur for each reaction zone, reduce treatment effect.Meanwhile aerobic bacteria is from generation to generation
Cycle is short, and breeding is fast, and caused sludge quantity is excessive, causes Treatment of Sludge cost high.Meanwhile there is structure in existing integration apparatus
Single, pure steel structure or concrete appearance are all incompatible with " fine rural area " and emit bad smell, make nearby villager be difficult to connect
The present situation received.With the construction of environmental new rural village, the environmental issue of villages and small towns sewage disposal turns into focal point.Film is oxygenated technology
As a kind of Novel sewage treatment technology, increasingly it is taken seriously, is almost at present sky in integrated sewage treating apparatus field
In vain, and traditional film oxygenation technology because multiple factors (film grows and the alternation procedure that comes off, everywhere by water pressure is different, resistance not
On an equal basis, micro-bubble can be formed to be oxygenated and overflow into water), it is difficult to foamless oxygen charging state is fully achieved；Traditional integrated sewage water
Arrange outside processing unit it is poisonous and harmful, have gas with foreign flavor more, influence surrounding environment.Vast villages and small towns area, due to confluence of rainwater and sewage
Present situation, reduce further the low ratio of carbon to ammonium of sewage, and then have a strong impact on sewage denitrification and dephosphorization qualified discharge, current single
Reactor in true efficient denitrogenation dephosphorizing almost without may.In order to which preferably power-assisted " fine rural area " is built, urgently need
Will a kind of environment-friendly, green sewage water treatment method.And from the point of view of combining current sewage disposal situation, most handling process
More single, treatment effect has limitation, is combined if kinds of processes is combined, and will bring more effective result.
The content of the invention
It is an object of the invention to overcome the coefficient of oxygen utilization of traditional biological membrane reactor not high, difficult, single without bubble oxygenation
Plane product biomass is low, processing mode is single, unsightly, safeguard a series of problems, such as complicated, sludge output is big, there is provided it is a kind of still
Formula film is oxygenated sewage-treating reactor and processing method.
A kind of to be oxygenated sewage-treating reactor without bubble film, it includes reactor body, oxygenation film wire component, plant；Institute
No bubble film oxygenation sewage-treating reactor is stated to be made up of processing system two parts on underwater processing system and the water surface；Described
Underwater processing system is by oxygenation film wire component and surface attachment biomembrane, root system of plant and surface attachment biomembrane and takes off
The active biological film fallen, which is coupled in, to be integrally formed；Processing system is made up of the cauline leaf of plant on the water surface, especially by photosynthetic
Effect realizes that metabolism is handled.
Described oxygenation film wire component is curtain hollow fiber film assembly or column-shape hollow fiber membrane modular；Described oxygenation
Film wire is aeration type hollow fiber film thread.
Described can act also as reactor without bubble film oxygenation sewage-treating reactor as single treatment reactor
Portion processing unit.

Body；It is oxygenated by hollow-fibre membrane, the biomembrane of oxygen envelope silk surface attachment is first with unnecessary oxygen is then by plant roots
The biomembrane for be the biomembrane of surface attachment, departing from makes full use of so that and formed in reactor and supply oxygen still state, can maximum journey
Coefficient of oxygen utilization is caused to reach maximization on degree, coefficient of oxygen utilization can almost reach 100%, and the expense of aeration energy consumption can be greatly lowered
With.
2nd, it is oxygenated sewage-treating reactor without bubble film using one kind so that reaction of high order can be able in a reactor
Realize；Unique system offering oxygen way, the biomembrane in system is mostly amphimicrobe, flora of having the advantage；In addition, low oxygen supply can be big
It is big to reduce denitrifying carbon source amount, solve the big problem of conventional art organic carbon source dosage；Because the metabolic type of amphimicrobe determines
Its generation cycle is much smaller than aerobic microbiological, compared to traditional aerobic treatment technique, reduces sludge yield coefficient.Can be significantly
Degree reduces sludge yield coefficient；The autodigestion rate of death of sludge, can reach the dynamic of sludge autodigestion and sludge growth
Balance, dead sludge can be reused as denitrification organic carbon source, substantially reduce the generation of sludge quantity.
3rd, root system of plant biomembrane, film wire surface attachment biomembrane, come off biomembrane, three parts biological film coupling is in one
Body interacts so that and the microorganism in reactor fully coordinates, utilized mutually, and biomembrane can obtain good growing environment,
Anti- load impact is strong；And root system of plant is fluffy, the state of floating is more advantageous for mass exchange in water, improves the place of system
Manage effect.
4th, integrated sewage treating apparatus can not only remove the pollutant in sewage disposal, also can remove surrounding environment
Poisonous and harmful to have gas with foreign flavor, multiple effect is in one；Emergent aquactic plant is planted on reactor and effectively absorbs and sheltered sewage
Caused peculiar smell in processing procedure, root system of plant can also absorb substantial amounts of nitrogen phosphorus etc. in sewage except coupled biological film process
Nutrient and pollution organic matter；And the function that plant is beautified the environment makes reactor be perfectly combined with " fine rural area " environment；
People are overturned simultaneously to recognize traditional sewage-treatment plant, comply fully with national green, environmental protection, sustainable theory, it is and fine
Rural environments combine together.
