Water is the basis in ecological residential area. It is very important to recycle the water resource in the designing and
planning of the ecological residential quarter due to the critical way to realize the wastewater resource utilization. In this
paper, a new technology of waste water treatment is introduced, which is ORGANIC A ecotechnology. We integrate the
trad itio nal waste wat er t reat ment tec hnolo g y and mode rn ec ol ogic al e ngine eri ng te ch nolo gy to get her a nd app ly the inte-
grated technology in the treatment of domestic sewage. The treated water can be reused for landscape and greening,
which can beautify the residential area and recycle wastewater.

1. Introduction
The shortage of water resources has become a globally
serious problem. The sewage after appropriate treatment
and the reuse of the recycled water have become the
consensus of all over the world. The wastewater recla-
mation and reuse, in the existing sewage concentrated
treatment, need, will the process which is similar to the
water supply pipe network city recycled water distribu-
tion system, after the network system and a series of
midway lifting pump stations and distribution to users.
Thus, the urban pipeline system occurs at least three
times in conveying. However, the conveying process
wastes a large amount of capital cost and operation cost.
This part of the investment has become a huge economic
burden and more than the cost of urban sewage concen-
trated treatment plant, and due to the leakage problems
on water resources will also cause the second pollution.
Sewage concentrated treatment obviously has its limita-
tions, at present many water treatment scientists are ac-
tively advocate in situ treatment in situ, and to realize
the reuse water balance and water circulation system
In recent years, a new processing system, which is
called the distributed processing and reuse system, start
to be used widely in some countries, especially in the
Netherlands, Germany, Scandinavia areas. It can over-
come the shortage of the centralized wastewater treat-
ment system by using this system [2]. Ecological resi-
dential quarter waste water trea tment is se wage dispe rsion
processing mainly reflects, the plot sewage in situ collec-
tion, processing and recycling, processing more than
centralized economic and feasible. Thus, the water pollu-
tion not only can be c ontrolled, but also in situ treatmen t
after specific reuse, saving a large amount of the water
resources in order to meet the requirements of sustaina-
ble development; At the same time, it can also obtain
good economic benefit. There are many kinds of quarter
sewage treatment method. By using the latest foreign ad-
vanced technology, named ORGANICA ecological treat-
ment technology, combining the latest engineering tech-
nology and the traditional wastewater treatment technol-
ogy together, has the broad prospect.
2. Present Situation of Ecological Residential
Sewage Reuse at Home and Abroad
There are more than 20 years of history fo r the const ruc-
tion of foreign ecological residence sewage reuse, and
there are many experiences. Many countries have formed
their characteristics. According to their own national con-
ditions and adopting different technical means to solve
the problem of resources and energy, meeting or satisfy-
ing partly due to water shortage limit city need to be
fairly good social benefits and economic benefits. Den-
mark is one of earliest country to implement the ecologi-
cal residential engineering, as early as in the end of 1984,
a demonstration project called “not allergic housing” in

Aarhus. Residential use a series of water saving technol-
ogy measures, including residential area sewage through
the small sewage pro c e sso r in situ treatment, will become
sewage water, make residential area water saving 30%,
but also improved the environment of the whole [3].
Each design aimed for maximum limit protecting natural
resources and minimal impact on environment in a zero
energy consumption community in London, waste water
in the community through the small sewage processor
system in situ treatment, the wastewater can be recycled
[4]. Israel is located in the eastern Mediterranean, with
most of the arid and semi-arid area, the country's small
community life sewage in situ reuse, 100% of life se-
wage reuse [5]. North America is the developed areas
using sewage reuse in the world. There are 357 cities
reuse sewage, and 536 regeneration recycling stations.
Japanese land area is small, the large population, water
resources occupancy is lower than the world average
level, because Japanese government puts forward the
"water" concept, in 1990, and sets up 1369 reuse engi-
neering all over the country [6]. There are 50000 metric
tons of recycled water back to used for landscaping, in-
dustrial every day in Mecca and Jeddar, Saudi Arabia [7].
The water supply reaches for 1.13 million tons per day,
of which 85% is the use of urban sewage as water each
day, 94000 tons of drinking water from regenerative wa-
terworks in Johannesburg, Republic of South Africa. The
low polluted sewage is directly used as irrigation, and
has achieved good economic benefit in Thessaly, Greek
The ecological residence research, construction and
sewage reuse started late in China. Since the 1980s, Chi-
nese architects also made many try, made some prelimi-
nary success experience, but need to be widespread to
form the situa tion of large scale development of the eco-
logical residential sewage reuse. The sewage of the new
capital manor quarter in Tianjin was treated with all, on
craft chose CMR sewage treatment technology, the water
processing system treated sewage, used in the water,
greening, road flushing, etc., saving the water spending
greatly for the people and property management units[9].
At an ecologica l resident ial quarter in Ha iko u, C hina , th e
design of sewage treatment adapt soil toilet, kitchen
washing wastewater and other life sewage separation of
interior drainage pipe processing respectively, forming a
residential area sewage purification, rainwater collection,
gray water utilization the integrity of the ecological sys-
tem. In an ecological residential quarter in Shenyang,
China, it adopted in depth sewage treatment to realize
part of reclaimed water reuse, and created the good bene-
fit [10]. Government pays more and more attention to
water recycling, and there are vigorously explore on the
reuse technology in each local government, and to make
the technology more and more mature.
3. ORGANICA Technology
ORGANICA ecological treatment technology was firstly
put forward in the United States of America. O RGANICA
Company shall be responsible for the later research, de-
velopment, technology promotion and engineering ap-
plication. The company was established in 1998, set up
in Budapest, Hungary. This technology integrates the
modern ecological engineering technology and the tradi-
tional wastewater treatment technology as an organic
3.1. The Principle of ORGANICA Technology
Wastewater treatment methods used activated sludge.
According to the water quality index, process selection
A2 / O or A/O process, ecological system in plant fixed
with iron rack, the typical process flow see Figure 1.
Wastewater treatment principle is to integrate the tra-
ditional activated sludge process and ecological engi-
neering technology as a whole, that is firstly anaerobic,
anoxic, and then aerobic reaction. In the aerobic reaction,
the whole device vaccinate 2000-3000 species of plants,
animals and microbes, besides the traditional activated
sludge system of biological bacteria in vitro. These or-
ganisms have self synthesis and the capacity of absorbing
the so la r e ner g y, wh ich c a n i mpr ove the s ys t e m to ha ndl e
ability, improve water q uality.
3.2. The Characteristics of ORGANICA
ORGANICA technology has traditional activated sludge
process characteristic, but a lso has the follo wing features:
(1) the ecological treatment system have 2000-3000 spe-
cies of plants, animals and microbes, these organisms
promote the system processing ability; (2) more kinds of
biological system, the variety is complete, the formation
of ecological system stability, metabolism ability is
strong, can realize quick start; (3) contaminated water in
turn cascade flow through the naturalized but have dif-
ferent ecological structure of the processing unit, ensure
treatment plant with good ecological purification func-
tion and flexibility of operation; (3) appearance design
beautiful, have a kind of natural beauty, a decorative
flowers and wastewater treatment plant as a plant garden,
can be used in the most strict requirement of high-grade
community life sewage purification and reuse; (4) the
construction investment and operation cost is low and the
effluent can meet the greening, flushing and water reuse
requirements, but also can be used as ecological land-
scape make-up water; (5) ORGANICA wastewater eco-
logical treatment device has a snail and other senior ani-
mals participate in the treatment process, reduce the
amount of excess sludge, reduce sludge treatment cost,
built-in biological filter to eliminate the od or pollutio n.

Compared with the traditional activated sludge process,
this system cause has higher system processing capacity,
good ecological purification function and operating flex-
ibility and investment and operation cost is low, water
reuse recycling value is big, the application range is quite
extensive. So if the ecological residential district suc-
cessfully applied this technology to treat sewage has
great economic benefits, ecological benefits and social
3.3. ORGANICA Technology Application
At present this technology in ORGANICA company host
country Hungary many places to use, and treatment ef-
fect is good, processing water quality can meet our coun-
try landscape water standard (GB/T18921-2002). Poland’s
Notincs three autonomous region also use this technolo-
gy to treat sewage. ORGANICA ecological treatment
technology was used on the purification design of large-
scale municipal development in Laytown, Ireland. Other
countries, such as Ukraine, Russia, and Australia and so
on also applied the same technology.
The technology has not been popularized in large-scale
in China. Shenzhen was the first city to introduce the
technology in 2008. At present it as used in a certain de-
gree in Shenzhen and other cities. The technology per-
formance is very stable from the view of operation. Be-
cause the temperature is higher in South China, winter
greenhouse dont need heat preservation measures, the
plants in a greenhouse to grow in all the year round, the
sewage treatment and stable operation, creates the condi-
tion is feasible in theory the. To ORGANICA technology
in our country ecological residential use of research,
there will be a lo t of value.
4. Future Work
The sewage treatment tech nology separated the traditional
sewage treatment technology from the modern engineer-
ing technology in the past. Those treatment technologies
mainly dischar ge the se wage into artif icial wetla nd to the
deepening processing which needs two steps and two
different places, taking up a large amount of land area.
While ORGANICA technology integrates the traditional
sewage treatment technology and modern ecological en-
gineering technology as a whole, which can finish se-
wage treatment in the same place, and achieve water
reuse standard. This technology is still not popularized
and applied in large scale in China. Currently, it is used
tentatively in Shenzhen. Due to the ecological system
and the different climatic conditions in China, it is ex-
pected to be used in large-scale if the technology is im-
proved according to actual situation.
