Description
Technical field
The present invention relates to technical field of sewage treatment equipment, particularly a kind of improved biological carrier sewage treatment device.
Background technology
With the industrialization of the country, the process of urbanization, the discharge capacity of trade effluent is significantly increased, and being treated as sewage can
The problem of in the urgent need to address in sustainable development, and for the sewage containing large amount of organic, a kind of existing conventional processing side
Method is biomembrance process, and biomembrance process is in the microorganism on some solids surfaces using apposition growth（That is biomembrane）Carry out organic
The method of sewage disposal, biomembrane adsorbs attachment water layer organic matter first, is decomposed by the aerobic bacteria of aerobic layer, enters back into and detest
Gas-bearing formation carries out anaerobic digestion, and flowing water layer then washes out the biomembrane of aging to grow new biomembrane, and so on to reach
Purify the purpose of sewage.This method needs to use bio-carrier to form biomembrane, and conventional carrier has combination, elastic filler
PVC suspension balls etc. a, it may appear that problem is exactly that its biofilm speed is low, and film amount is small, the tight ness rating between biomembrane and filler with
Compatibility is not good, and coefficient of oxygen utilization is low in device, it may appear that region is unsaturated and supersaturation, organic impurities clearance compared with
It is low.
The content of the invention
It is contemplated that at least solving one of above-mentioned technical problem in correlation technique to a certain extent.Therefore, this hair
It is bright to propose a kind of improved biological carrier sewage treatment device.
The technical solution adopted for the present invention to solve the technical problems is：
It is disposed with from the bottom up in a kind of improved biological carrier sewage treatment device, including reaction tank, the reaction tank
Porous particle is filled with water inlet, suspended chain movable aerator and delivery port, the reaction tank.
As the improvement of above-mentioned technical proposal, the porous particle uses coal grain or volcanic rock or diatomite or swelling
Soil particle.
As the further improvement of above-mentioned technical proposal, the particle size range of the porous particle is 1.5-2.5mm.
Further, the fill volume of the porous particle is 3000-5000mg/L.
Further, the water intake velocity of the water inlet can according to the air demand or dissolved oxygen content or gas-water ratio in reaction tank come
From main regulation.
Further, the suspended chain movable aerator uses variable micro-hole formula aerator.
The beneficial effects of the invention are as follows：Using porous particle as bio-carrier, compared with traditional carrier, because it is more
The characteristic in hole, adsorption activity is good, can form inside and outside duplicature, and more prolonged practicality, biofilm speed is high, and film amount is big, and biomembrane is with filling out
With compatibility more, organic matter removal is better for tight ness rating between material, using suspended chain movable aerator, what it was produced
Gas residence time of ducking in drink is long, it is to avoid the region of traditional immobilized film device is unsaturated and supersaturation, therefore, oxygen
Utilization rate is high, theoretical power efficiency high, and is easy to maintenance, can be in the case where not stopping the supple of gas or steam, not being vented structures, by aerator
Directly being left the water from water can be safeguarded and be repaired.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is schematic structural view of the invention.
Embodiment
Reference picture 1, the biological carrier sewage treatment device of a modification of the present invention, including reaction tank 1, the reaction tank
It is disposed with water inlet 2, suspended chain movable aerator 3 and delivery port 4, the reaction tank 1 and is filled with from the bottom up in 1
Porous particle 5, the porous particle 5 is preferably using coal grain or volcanic rock or diatomite or bentonite clay particle, using porous
Grain 5, can make particle become " A/O " point of flowing, to dirt in particle appearance formation " O " aerobic film, internal layer formation " A " anoxic film
NH in water3- H, which continues aerobic nitrification, turns into N2, the content of nitrogen in sewage is reduced, polyP bacteria can be similarly converted into can be directly same
The orthophosphates of change, reduces the content of phosphor in sewage, simultaneously because " A " film is under specific anaerobic environment, meeting abrupt release goes out
Elemental oxygen, supplies top layer " O " film, this reduces the about 40-50% of the dissolved oxygen content in sewage, and organic removal rate is high, at sewage
Manage effect good.
It is preferred that, the particle size range of the porous particle 5 uses 1.5-2.5mm, and fill volume uses 3000-5000mg/
L.Also, the water intake velocity of the water inlet 2 can come from homophony according to the air demand in reaction tank 1 or dissolved oxygen content or gas-water ratio
Section, makes whole device applicability stronger.
Using suspended chain movable aerator 3, its gas produced residence time of ducking in drink is long, it is to avoid traditional fixation
The region of aerator is unsaturated and supersaturation, therefore, coefficient of oxygen utilization are high, theoretical power efficiency high；Due to mobile exposure
Gas mode causes to form the wave distribution of dissolved oxygen concentration in aeration tank, so that beneficial cenobium is in unsteady state in water
Under, and the influence key factor under unsteady state condition for biological treatment system is the influence to the microorganism in system, including
Microbial activity, adapt to external environment ability, the formation of microorganism with specific function in terms of, can be pierced under unstable state
Swash microorganism and improve activity, greatly improve the disposal ability of microorganism；And all fasteners of suspended chain movable aerator 3 are equal
On the water surface, maintenance is so facilitated, in the case where not stopping the supple of gas or steam, not being vented structures, aerator is directly proposed from water
The water surface can be safeguarded and repaired, easy to use.
Further, the aerating system 3 uses variable micro-hole formula aerator, pore type aerator aeration bubble diameter
Small, gas-liquid interface diameter is small, and gas-oil interfaces are big, and bubble diffusion is uniform, will not produce eyelet blocking, and corrosion resistance is strong, and can
Intermittent duty, is particularly suitable for use in municipal sewage treatment, and use is very simple and convenient, and aerating system 3 can make the life of fluid bed biofilm
Thing flco is in " Brownian movement " state, accelerates biodynamic reaction degradation of organic substances pollutant.
Above concrete structure and sized data are that presently preferred embodiments of the present invention is illustrated, but present invention wound
Make and be not limited to the embodiment, those skilled in the art can also make kind on the premise of without prejudice to spirit of the invention
The equivalent variations planted or replacement, these equivalent deformations or replacement are all contained in the application claim limited range.
