本工程污水中有机成份较高，可
生化性较好，因此采用生物处理方法大幅度降低
污水中有机物含量是最经济的。由于污水
中氨氮及有机物含量较高，特别是有机氮，
在生物降解有机物时，有机氮会以氨氮形式表
现出来，氨氮也是一个重要的污染控制
指标，因此污水处理采用缺氧好氧
A/O
生物接触氧化工艺，即生化池需分为
A
级池和
O
级
池两部分。
调节池内污水采用污水提升泵提升至
A
级生化池，进行生化处理
。在
A
级池
内，由于污水中有机物浓度
较高，微生物处于缺氧状态，此时微生物为兼性微生物，
它们将污水中有机氮转化为氨氮
，同时利用有机碳源作为电子供体，将
NO2-N
、
NO3-N
转化为
N2
，
而且还利用部分有机碳源和氨氮合成新的细胞物质。所以
A
级池
不仅具有一
定的有机物去除功能，减轻后续
O
< br>级生化池的有机负荷，以利于硝化作用进行，而且依
靠污水中的高浓度有机物，完
成反硝化作用，最终消除氮的富营养化污染。经过
A
级池
的生化作用，污水中仍有一定量的有机物和较高的氮氨存在，为使有机物进一步氧化
分解，同时在碳化作用趋于完全的情况下，硝化作用能顺利进行，特设置
O
级生化池。
The organic
components of the sewage for this
project is rich and biodegradability is
good, so it is the most economical when
using
biological treating
technology to reduce the
organic
components
in
the
sewage.
Because
the
percentage
of
ammonia
nitrogen
and
organic
components
are
high,especially
for
organic
nitrogen,it
will
emerge
in
the
form
of
ammonia nitrogen during the degradation
of organic compounds. The ammonia nitrogen is
an important control index for
pollution, so the sewage treatment uses
aerobic-anoxic A/O
biological
contact
oxidation
technology,that
is,biochemical
pool
needs
to
be
divided
in
A
level
pool
and
O
level
sewage
in
regulating
reservoir
will
be
lifted
to
Grade
A
biochemical
pool
with
sewage lift pump
for biochemical
grade
A pool,due to
high concentration of organic matter in
the sewage, microorganism lacks the oxygen,at this
moment,it is aerobic-anaerobic microbe
and they convert the organic matter into ammonia
the
same
time,it
uses
the
organic carbon source
as
electron
donor,change
NO2-N
、
NO3-N
into
N2.
Furthermore,it
uses
part
of
organic
carbon source
and
ammonia
nitrogen to compound the new cellular
grade A pool not only has the removal
function of organic matter and reduce
the organic loading of Grade O biochemical pool,it
is
good for the proceeding of
nitrification,reply on the highly concentrated
organic matter in the
sewage and finish
the denitrification,eliminate the eutrophication
pollution of
the biochemical
action of Grade
A pool,there
is
still certain
amount
of organic matter and
high
percentage of nitrogen ammonia, for the further
oxygenolysis and smooth
running of
nitrification,when carbonification is
almost completed,set the Grade O biochemical pool.

A
级池出水自流进入
O
级池，
O
级生化池的处理依
靠自养型细菌（硝化菌）完成，
它们利用有机物分解产生的无机碳源或空气中的二氧化碳
作为营养源，将污水中的氨
氮转化为
NO
2
-N
、
NO
3
-N
。
O
级池出水一部分进入沉淀池进行沉淀，另一部分回流至
A
级
池进行内循环，以达到反硝化的目的。在
A
级和
O
级生化池中均安装有填料，整个生
化处理过程依赖于附着在填料上的多种微生物来完成的。在
A
级池内溶解氧控制在
0.5mg/l
左右；在
< br>O
级生化池内溶解氧控制在
3mg/l
< br>以上，气水比
15:1
。
The effluent of Grade A pool water
flows into Grade O pool by itself, the processing
of
Grade O biochemical pool depends on
autotrophic bacteria to complete, they take
advantage
of decomposition of organic
matter to generate inorganic carbon source or
carbon dioxide in
the air as nutrition
source, ammonia nitrogen in wastewater can be
converted to NO2-N
、
NO3-N.
The part of effluent from Grade O pool flows into
settling basin for precipitation,
another
part
returns
to
Grade
A
pool
for
inner
loop
to
achieve
the
goal
of
denitrification.
They are installed with filler in Grade
A and Grade O biochemical pool , the whole process
of biochemical treatment depends on a
variety of microorganisms which are attached to
the
filler.
The
dissolved
oxygen
in
Grade
A
pool
will
be
controlled
at
about
0.5mg/l.
The
dissolved oxygen in
Grade O pool will be controlled above 3mg/l, the
rate of gas and water
is 15:1.
< br>O
级生化池一部分出水回流进入
A
级池；一部分流入斜管沉淀池进行固液分离。
One
part of effluent from Grade O biochemical pool
will flow back into Grade A pool;
another part will flow into inclined
tube settling basin for solid-liquid separation. <
/p>
沉淀池固液分离后的出水进入消毒排放池，经过固体氯片消毒，杀灭出水中可能
含有的活性微生物，以确保出水水质达标排放。
The
water

、一体化生活污水处理设备
The integration of sewage
treatment equipment
一体化设备由缺氧池、好氧池、沉淀池、消
毒排放池、污泥消化池组成。
The
all-in-one
equipment
is
composed
of
anoxia
pond,aerobic
tank,settling
pond,disinfection and emission pond and
sludge digestion tank.
缺氧池主要利用反硝化菌、聚磷菌及其它厌氧或兼氧菌，去除
N
、
P
，将大颗粒杂
质
分解成为小颗粒杂质、将难降解杂质分解成易降解杂质，减轻后续处理设施的负担。
在缺
氧级池内，由于污水中有机物浓度较高，微生物处于缺氧状态，此时微生物为兼
性微生物
，它们将污水中有机氮转化为氨氮，同时利用有机碳源作为电子供体，将
NO2--
N
、
NO3--N
转化为
N2
，而且还利用部分有机碳源和氨氮合成新的细胞物质。所
以缺氧级池不仅具有一定的有机物去除功能，减轻后续生物接触氧化池的有机负荷，
以利于硝化作用进行，而且依靠污水中的高浓度有机物，完成反硝化作用，最终消除
氮的富营养化污染。经过缺氧池的生化作用，污水中仍有一定量的有机物和较高的氮
氨存
在，为使有机物进一步氧化分解，同时在碳化作用趋于完全的情况下，硝化作用
能顺利进
行，特设置生物接触氧化池，生物接触氧化池的处理依靠自养型细菌（硝化
菌）完成，它
们利用有机物分解产生的无机碳源或空气中的二氧化碳作为营养源，将
污水中的氨氮转化
为
NO2--N
、
NO3--N
。在缺氧池和生物接触氧化池中均安装有填料，
整个生化处理过程依赖
于附着在填料上的多种微生物来完成的。在缺氧池内溶解氧控
制在
0.5mg/l
左右；在生物接触氧化池内溶解氧控制在
3m
g/l
以上。生物接触氧化池出
水一部分回流至调节池进行内循
环，以达到反硝化的目的。
The anoxia pond
mainly makes use of denitrifying bacteria,
phosphorus-accumulating
bacteria and
other anaerobic bacteria to get rid of N, P ,
decompose the big particle impurity
to
small
particle
impurity,decompose
difficult
degradation
impurities
to
easy
degradation
impurities,
reduce the burden of subsequent
treatment
the anoxia pond,
due to
the
high
concentration
of
organic
matter
in
the
sewage,
microorganisms
are
in
hypoxia
condition.
At
that
moment,microorganisms
are
for
facultative
which
converts
organic
nitrogen
to
ammonia
nitrogen,meanwhile
use
organic
carbon
source
as
electron
donor,convert NO2--
N
、
NO3--N to N2,moreover make
use of part of organic carbon source
and
ammonia
nitrogen
to
compound
the
new
material.
So
anoxia
pond
not
only
has
the
removal function of organic matter and
reduce the organic loading from the contact
between
subsequent
living
matter
and oxidation
pond,it
is
good
for
the
proceeding
of
er
it
relies
on
the
highly
concentrated
organic
matter
to
finish

denitrification
process,finally
remove
the
eutrophication
pollution
of
the
biochemical
action
of
anoxic
pond,there
is
still
a
certain
amount
of
organic
matter
and
ammonia
nitrogen
in
the
sewage,in
order
to
decompose
the
organic
matter
for
further
step
,when
carbonification
is
completed
almost,
nitrification
can
proceed
the
biological
contact
oxidation
pond
specially,the
treatment
in
it
depends
on
autotrophic
bacteria(nitrobacterium)
to
take
inorganic
carbon
source
decomposed
by
organic matter or carbon dioxide in air
as the nutrient source,change the ammonia nitrogen
in
the sewage to NO2--
N
、
NO3--N. Packing is
installed in anoxic pond and
biological
contact oxidation pond, the whole process of
biochemical treatment depends
on
a
variety
of
microorganisms
which
are
attached
to
the
dissolved
oxygen
in
anoxic
pond
will
be
controlled
at
about
0.5mg/l,dissolved
oxygen
in
biological
contact
oxidation pond will be controlled above
3mg/l,one part of discharging water from
biological
contact oxidation pond will
return to
regulating
reservoir for internal recycle to achieve the
goal of denitrification.
好氧池是以生物膜法为主，兼有活性污泥法的生物处理装置，通过回转式鼓风机
提供氧源，在该装置中的有机物被微生物所吸附、降解，使水质得到净化。
The aerobic pool is biological
treatment unit which is mainly through biofilm
method
and has activated sludge
process, provide the oxygen through a rotary
blower, organic matter
in the device
will be absorbed and degraded by microorganism to
purify the water quality.

剩余污泥定期清理，

、调节池
Regulating reservoir
由于污水排水的周期性和水质的不均匀，为保证后续处理设施的正常运行，设置
调节池以调节水量和均化水质。调节均化池采用碳钢防腐结构。
Due to the periodic drainage of sewage
and uneven water quality , in order to guarantee
the
normal

of
the
subsequent

facilities,
set
the
regulating

、一体化
生活污水处理设备
The integration of sewage
treatment equipment
一体化设备由缺氧池、好氧池、沉淀池、消
毒排放池、污泥消化池组成。
The
all-in-one
equipment
is
composed
of
anoxia
pond,aerobic
tank,settling
24
pond,disinfection and
emission pond and sludge digestion
tank.
缺氧池主要利用反硝化菌、聚磷菌及其它厌氧或兼
氧菌，去除
N
、
P
，将大颗粒杂
质分解成为小颗粒杂质、将难降解杂质分解成易降解杂质，减轻后续处
理设施的负担。
在缺氧级池内，由于污水中有机物浓度较高，微生物处于缺氧状态，此时
微生物为兼
性微生物，它们将污水中有机氮转化为氨氮，同时利用有机碳源作为电子供体
，将
NO
2
-
-N
、
NO
3
-
-N
转化为
N
2
，而且还利用部分有机碳源和氨氮合成新的细胞物质。所以
缺氧级池不仅具有一定的有机物去除功能，减轻后续生物接触氧化池的有机负荷，以
利于
硝化作用进行，而且依靠污水中的高浓度有机物，完成反硝化作用，最终消除氮
的富营养
化污染。经过缺氧池的生化作用，污水中仍有一定量的有机物和较高的氮氨
存在，为使有
机物进一步氧化分解，同时在碳化作用趋于完全的情况下，硝化作用能
顺利进行，
特设置生物接触氧化池，
生物接触氧化池的处理依靠自养型细菌
（硝化菌）
完成，它们利用有机物分解产生的无机碳源或空气中的二氧
化碳作为营养源，将污水
中的氨氮转化为
NO
< br>2
-
-N
、
NO
3
-
-N
。在缺氧池和生物接触氧化池中均安装有填料，整个
生化处理过程依赖于附着在填料
上的多种微生物来完成的。
在缺氧池内溶解氧控制在
0.5mg
/l
左右；在生物接触氧化池内溶解氧控制在
3mg/l
以上。生物接触氧化池出水
一部分回流至调节池进行内循环，以达到反
硝化的目的。
The anoxia pond
mainly makes use of denitrifying bacteria,
phosphorus-accumulating
bacteria and
other anaerobic bacteria to get rid of N, P ,
decompose the big particle impurity
to
small

impurity,decompose
difficult

impurities
to

impurities,
reduce the burden of subsequent
treatment
the anoxia pond,
due to
the
high
concentration
of
organic
matter
in
the
sewage,
microorganisms
are
in

At
that
moment,microorganisms
are

NO3--N to N2,moreover make
use of part of organic carbon source

So
anoxia
