Description
Technical field
The invention belongs to technical field of sewage, specially a kind of denitrogenation aerobic granular sludge reactor and sewage disposal
Method.
Background technology
In recent years, with Urbanization Progress, China's water pollution is dirty from " Organic Pollution " that COD is representative to nitrogen
" eutrophication pollution " conversion of dye.Nitrate pollution is serious in water body environment, caused by the exceeded institute of nitrogen lake alga eruption and
Coastal " red tide " occurs again and again, but China's traditional activated sludge process sewage treatment plant technique more at present does not still have efficiently
Denitrification ability, sewage treatment plant tail water qualified discharge becomes problem in the urgent need to address.Conventional activated sludge process is to total nitrogen
Removal efficiency is relatively low, is to improve denitrification effect, and enhanced nitrogen removal process is developed on the basis of conventional activated sludge process（Such as detest
Oxygen-anoxic-aerobic process）, microbial function subregion is realized by arranging with reaction member of the different dissolved oxygen containing rate, enter
And realize denitrification denitrogenation.Due to needing to build independent reaction unit and sludge reflux, enhanced nitrogen removal process increased construction and
Operating cost.On the other hand, municipal wastewater is generally required the characteristics of especially small town sewage has the low ammonia nitrogens of COD high
Carbon source is added in denitrification process, so as to increased the cost of denitrogenation.
Aerobic particle mud has fine and close structure, good settling property, at impact resistance and good pollutant
Reason ability.Restriction inside it due to resistance to mass tranfer to dissolved oxygen, with ecto-entad aerobic zone-anoxic plot structure is formed, and is
Denitrification microorganism group provides suitable living environment, there is synchronous nitration and denitrification effect inside particle, makes aerobic grain
Sludge has good denitrification effect, and need not additionally arrange denitrification pond and external carbon addition.Due to aerobic particle mud work
Skill need not be independently arranged second pond and denitrification pond, which reduce 75% floor space and 50% energy consumption.
At present aerobic particle mud method is mainly used in and butchers, and the high intensity wastewater treatment such as brewages（The kg/ of volumetric loading 3
COD·m3More than d）, with good pollutant removing effect.But in low-intensity flow condition（The kg/ of volumetric loading 1.5
COD·m3Below d）Under, it is poor that aerobic particle mud has that total nitrogen removal effect is processed.At present, most of cities of China
Political affairs sewage treatment plant inflow concentration and load are relatively low（Influent COD is less than 500mg/L, and volumetric loading is less than 1.5 kg/COD
m3·d）, the application to aerobic particle mud technique causes restriction.Under high intensity flow condition, aerobic particle mud growth speed
Rate is fast, the dense granule larger so as to form particle diameter（Average grain diameter is up to more than 1cm）.The restriction of resistance to mass tranfer make dissolved oxygen without
Method is infiltrated through inside particle, and the aerobic-anaerobic area of ecto-entad is defined in grain structure, and for denitrification microorganism, group provides
Suitable living environment, so as to good synchronization denitrification effect.And under low-intensity flow condition, aerobic particle mud life
Length is slack-off, and the grain diameter of formation is little（Average grain diameter is less than 0.5mm）, resistance to mass tranfer is low, makes that dissolved oxygen is permeable to enter particle
It is internal.Meanwhile, COD and ammonia nitrogen make dissolved oxygen content in reactor go up rapidly by rapid oxidation under low-intensity flow condition, enter
One step promotes mass transfer of the dissolved oxygen inside particle, it is suppressed that synchronous nitration and denitrification is acted on.By reducing aeration intensity energy
Dissolved oxygen content is reduced, but while reduces hydraulic shear.Research shows that high hydraulic shear is conducive to the generation of extracellular polymeric,
Its effect is the hydrophobicity that improve aerobic particle mud, reduces surface Gibbs free energy, enhances sludge affinity, is entered
And promote granulating.When hydraulic shear is reduced, the stability of aerobic particle mud declines rapidly, is easily caused granule sludge mistake
It is steady to disintegrate.Therefore under the low-intensity flow condition of the high ammonia nitrogens of low COD, aerobic particle mud denitrification effect how is lifted into based on
Study a question.
