Embodiment：
In this example, setting drop flow is 250mL/min, and drop depth h=20cm, drop plate perforated strip aperture D=
5mm, drop board group part in deflector 11 inclination alpha=0 °.There is drop plate respectively and without under drop slat element, passing through clear water
Standard total oxygen transfer coefficient when obtaining different drop height H=32cm, 40cm, 50cm, 60 cm, 70cm, 80cm can be tested
KLas。
Oxygen in air is transmitted to liquid phase from gas phase and belongs to substance diffusion process, and according to Fick (Fick) law, substance exists
The concentration differences of interface both sides pushes material molecule to shift from the higher side of concentration to relatively low side to spread, i.e., substance diffusion rate with
Concentration gradient is proportional.Based on " double-film theory " that Lewis and Whitman is established, aerobic process is gas-liquid mass transferring process, oxygen
It is shifted from gas phase to liquid phase.According to the oxygen consumption situation in liquid phase, the oxygen transmission in aerobic process is divided into two kinds of situations：
(1) under the conditions of certain environment (temperature, air pressure etc.), there are oxygen consumptions, oxygen consumption rate to be indicated with R in liquid phase, then oxygen
Transmittance process is expressed as with the differential equation：
In formula：
KLa：Total oxygen transfer coefficient under test condition, 1/min；
CS：Dissolved oxygen concentration, mg/L are saturated under test condition in water；
C：T times corresponding oxygen in water concentration, mg/L；
R：Oxygen consumption rate, (kg/m3﹒ hr)
t：It is oxygenated time, min.
When oxygen consumption be equal to oxygen transmission capacity, i.e.,Belonging to liquid phase, there are the stable states of oxygen consumption situation.
(1) oxygen consumption, i.e. oxygen consumption rate R=0 are not present in liquid phase
Increase with oxygenation capacity, oxygen concentration moves closer to or reach saturated concentration in liquid phase.The oxygen transmittance process differential equation
It is expressed as：
Above formula integral is arranged
㏑(CS- C)=㏑ C-KLa (2.3)
Clear water aerobic process belongs to the second situation, actual conditions also need to be corrected updating formula to temperature influence be.
KLas=KLa×θ20T (2.4)
Clear water oxygenation capacity is tested with Shi Ce ㏑ (CS- C) it is ordinate, time t is abscissa, the public affairs acquired with the Return Law
Slope is-K in formula (2.2)La.By KLaTotal oxygen transfer coefficient K under standard state can be acquired by bringing formula (3.4) intoLas。
KLasBigger, the transmission speed of oxygen is faster, this research is with standard total oxygen transfer coefficient KLas(20 DEG C) expression oxygenation capacities.
Test table 1-1, Fig. 4 are respectively to have drop board group part and always shift without the standard oxygen under the conditions of drop board group part and be
Number KLasWith drop height change relationship.
Can be obtained by Fig. 4, table 1-1, have drop board group part and without drop board group part under the conditions of, standard total oxygen transfer coefficient KLas
It increases and increases with drop height, after peaking, increase and reduce with drop height.Hideo Nakasone experiments
Conclusion is identical as this experiment, and result of study is within the scope of drop height 40cm ＜ H≤100cm, as drop height H=
When 60cm, standard total oxygen transfer coefficient KLasThere are maximum.This is because, on the one hand, drop height is higher, and the drop time is just
Longer, i.e., the time that the oxygen in air is contacted with water is longer, and the oxygen dissolved in water body is more；In addition, drop height is higher, fall
Falling water body is bigger to accepting masses hit power, can shift more oxygen to receiving water body.By formula (2.2) it is found that oxygenation rate
It is proportional with oxygen amount is lost in water body, it accepts and loses oxygen amount reduction in water body, water body oxygenation rate reduces, so, with drop height
It continues growing, oxygen amount is lost in water body and is reduced rapidly, oxygenation rate accordingly reduces.In addition, some scholars' result of study is shown, when falling
When water height H=80cm, standard total oxygen transfer coefficient KLasIncrease again with drop height and increase, this is because as height increases
Add, drop form is collected by initial water curtain, is in the form of a column and falls, to affect oxygen-transfer efficiency.This research drop flow
Small, drop does not collect, and influence of the flow to the plate components oxidation effect that drops of dropping needs further to be studied.
Table 1-1 drops height and KLasRelation table
Can be obtained by table 1-1, Fig. 4, when drop height 32cm ＜ H≤80cm when, have drop board group part assembly test group standard
Total oxygen transfer coefficient KLasIt is above without drop board group part assembly test group, illustrates the plate components efficient hardening drop energy that drops
Power.Analysis reason is that the plate components that on the one hand drop can be detained water body to increase the water body residence time, be more advantageous to water body
It is oxygen-enriched；On the other hand, drop plate components increase the contact area of water body and air.
In addition, drop height is higher, drop board group part assembly test group standard total oxygen transfer coefficient KLasWith without drop board group
Part assembly test group standard total oxygen transfer coefficient KLasDifference is smaller.It is when dropping height more than certain value to analyze reason, and drop plate
Components reoxygenation ability is oxygenated contribution rate more without significant change, the i.e. higher drop plate components of drop height to drop system
It is small.Drop plate components are more suitable for the low condition of drop height, and lower drop height reduces water to a certain extent
The waste of head, to reduce construction cost.
In conclusion in this example, using in the present apparatus treated sewage target contaminant COD, BOD5, NH4+-N,
TN, TP aqueous concentration are respectively 43mg/L, 20mg/L, 0.01mg/L, 14mg/L, 0.7mg/L, removal rate is respectively 80%,
92%, 99%, 50%, 79%.COD, BOD5, NH4+-N, TN aqueous concentration reach《Urban wastewater treatment firm pollutant is arranged
Put standard》GB18918-2002 level-ones A handles standard, and TP aqueous concentrations reach《Urban wastewater treatment firm pollutant emission mark
It is accurate》GB18918-2002 level-ones B handles standard.
The board group part oxygenation capacity that drops is big to total oxygen demand contribution margin.It is given birth to reference to A2O technology Calculation drop oxygenation and contact oxidations
The total oxygen-supplying amount of state sewerage estimates processing system drop oxygenation amount with overall design oxygen-supplying amount and actual machine oxygenation capacity difference,
Calculate drop oxygenation oxygen-supplying amount be 123L/h, to system total oxygen demand contribution rate be 47%.
Reflux can also be set in the present apparatus, the removal effect of intensive treatment system TN,
