Broadcast the special program "Smart Water Purification Pioneer"
In nearly 40 minutes of popular science language
Walk into the construction of the First Aviation Bureau
The third phase of the water purification plant in Bao'an District, Shenzhen
Uncover the secrets of urban domestic sewage
How to achieve water purification step by step
February 2023
Shajing Street, Bao'an District, Shenzhen
A new one has been added
Green, low-carbon and intelligent water purification plant
-- The third phase of the Shajing Water Purification Plant
The total area is about 6.19 hectares
Equivalent to 8.7 standard football fields
Serves a population of more than 500,000
It can cover Shajing Street and Xinqiao Street
Part of Songgang Street
and the future Airport New City area
The program goes into detail
Municipal domestic sewage
After precipitation, filtration, and bio-purification
Chemical purification, ultraviolet disinfection and other steps
Realize sewage entering the plant and purifying water leaving the factory
The final output water quality is reached
Quasi-Class IV standard on the surface
It can be discharged directly into nature
In order to achieve "semi-underground" construction
CCCC engineers use the caisson method for construction
Excavated to a depth of 28 meters in complex geological conditions
A deep foundation pit about the size of two basketball courts
This method has little disturbance to the surrounding area
High production efficiency
It can ensure the safety of construction
Sewage treatment of leftover sludge
After gravity compression, low-temperature drying and other processes
The moisture content of the treated sludge does not exceed 40%
It can be incinerated and recycled
CCCC engineers are in the process of advancing the project
Overcome multiple challenges
During the construction period
The project has always been ranked as a water project in Shenzhen
Top three on the red list of quality and safety assessment
and a record of 6 consecutive wins
The record of the first place in the quality individual score
I won it before and after
2022 Third Achievement Award for Green Construction
Shenzhen Quality Engineering Golden Bull Award
Guangdong Provincial Quality Structural Engineering Award and other awards
The third phase of the manhole water purification plant
Realized domestic sewage in the dry season
and the rain at the beginning of the rainy season
Collection and Processing
Effectively improve the ecological environment in the western part of Shenzhen
Turn sewage into treasure and resource utilization
It promotes the harmonious coexistence of man and nature
