The theme of this year’s World Environment Day is “Building Modernization and Achieving Harmonious Coexistence between Man and Nature”, and will be celebrated for the 52nd time on June 5, 2023. Water is the basis for the existence of life. No life can be separated from water. The water environment is extremely critical for everyone, having a direct impact on health and water use, but also affecting the life and health of surrounding plants and small animals.

On June 3, on the occasion of "World Environment Day", in order to let the public have a broader understanding of the important role of water environment in urban development, a theme themed "Water moisturizes Nanshan, symbiosis with the city - Nanshan The "Looking for Qingji" event was held at the Nanshan Cultural and Sports Center Square in Shenzhen. More than 500 citizens participated in various forms such as understanding the working principle of robotic drainage, watching sewage flocculation experimental demonstrations, and on-site interactive Q&A, and jointly unveiled the mystery of water environment management.

Punch in to explore the entire process of sewage treatment

Where does the sewage discharged by the city every day go? How do we make the water cleaner? How do we coexist harmoniously with the water? At the event site, knowledge display boards told the systematic knowledge of sewage treatment, attracting citizens and friends as explorers With the identity of water workers, they uncovered the topic of "how humans recycle water and how to coexist with nature."

Before participating in the event, many parents and friends reported that "the transformation of sewage into clean water is complicated and unclear". After checking in at the five stations of "community pipe network-municipal pipe network-water purification plant-water environment management-unconventional water resources application" After the activity, I quickly learned about the process and principles of urban sewage treatment. A parent at the scene told his children that if sewage treatment can be summarized in one sentence, it is the integration of "factory-station-network". If it is further expanded, it is from the community pipe network, the municipal pipe network, to the water purification plant treatment, and finally Reach standard discharge rivers and utilize unconventional water sources.

Water knowledge is extensive and profound. How many questions can you answer? Citizens actively participated in the multi-person question-answering activity on site. The topics of this event are mainly about water affairs knowledge and common sense in daily life. "When is World Environment Day?" "What is the 24-hour customer service hotline of Shenzhen Huanshui Group?" Before the host finished the question, some people couldn't bear to say it. Stand up and tell the answer. Some even work in division of labor with their children, with the children responsible for holding up placards and the parents responsible for answering questions.

At the event site, intelligent equipment such as QV, all-terrain robots, full water robots, capsule robots, and large buffalo dewatering robots were all on display. Under the operation of professional engineers, they attracted the attention of a large number of parents and children.

"The equipment we are seeing now is a monitoring robot. It uses an advanced pipeline inspection system and records inspection images through the camera on the front of the machine, allowing engineers to more accurately view the conditions inside the pipeline and provide guidance for pipeline repairs. Important basis." "The Big Buffalo waterlogging robot is a waterlogging robot that can be remotely controlled within 800m through a wireless remote control. It can drive into the water by itself for drainage operations. The wading depth can reach 700mm and the drainage capacity is 600m3/h. This kind of robot Its small size can be directly loaded and transported by pickup trucks and trucks, and it can easily enter and exit streets and residential areas with height restrictions and narrow roads to perform operations, making up for the dilemma that large equipment cannot be used in urban areas." The engineer explained to the citizens while operating. Many children performed hands-on operations under the guidance of professionals and gained an in-depth understanding of urban water supply and drainage.

In the small experimental classroom, the children watched intently as the staff used test tubes to demonstrate the flocculation phenomenon of water, and also asked many imaginative questions. The staff gave answers one by one and explained in detail daily water use tips. At the event site, the water affairs staff demonstrated the interactive learning methods of polyaluminum chloride (PAC) coagulation, pH testing, residual chlorine testing, and turbidity testing. While popularizing water and environmental knowledge to the children, they also inspired the children. Their thirst for knowledge has improved their awareness of protecting the water environment.

The children used their imagination on the graffiti board in the co-creation area and created a magical new world. Some regard it as the ocean and draw a wonderful ocean world; some regard it as the blue sky and draw a free blue sky; some regard it as a declaration board and write a beautiful declaration of protecting the environment.

This "World Environment Day" event is hosted by the Nanshan Administration Bureau of the Shenzhen Municipal Ecological Environment Bureau and the Nanshan District Water Conservancy Bureau, and is hosted by the Nanshan Branch of Shenzhen Huanshui Group and the Shenzhen Pipe Network Technology Service Company. Shenzhen Huanshui Group transforms professional and difficult "drainage knowledge" into an interesting and easy-to-understand "purification journey", fully demonstrating the wonderful process of turning sewage into clean water and recycling, and strives to enhance citizens' awareness of water conservation and water protection.

Guard the city’s “meridians”

Multiple measures are taken to enhance the “appearance” of the water environment

In recent years, Shenzhen Huanshui Group has been guided by the water quality goals of the Gonghe Village section of the Shenzhen Estuary and Maozhou River, insisting on making progress while maintaining stability, and has strived to promote the stable improvement of the water environment quality in the basin through a number of key measures.

With the efforts of Shenzhen Huanshui Group, water quality has been improved in both the dry season and rainy season, moving towards all-weather water quality standards; the centralized collection rate and the BOD concentration entering the plant have been improved, and the sewage system operates efficiently; through the source cleanup action and pipe network Through efficiency improvement measures, the water environment of rivers and lakes continues to improve.

Innovate the water supply and drainage management model to unblock the "meridians" of the water environment. Through the integration of water supply and drainage, the construction, operation and maintenance, and management of "one network and unified management" are the first in the country to realize the integration of water supply and drainage management into residential areas, opening up the integrated management of all factors and entire chains from the residential area to the river.

Improve and upgrade the "brain" of water affairs and give "wisdom" to the water environment. Shenzhen Huanshui Group uses more than 700 online monitoring signals, all-factor sensing, and accurate monitoring of the entire chain to achieve early warning and rapid alarm positioning, ensuring safe operation of the system and continuous improvement of the water environment.

Create a series of high-quality projects to expand the "capacity" of the water environment. In recent years, Shenzhen Huanshui Group has built one garden-style water purification plant after another that benefits the neighborhood: the Futian water purification plant is built on top of a football theme park, which is the first in the country; the Honghu water purification plant has turned "NIMBY" into "neighborly", "One factory, one garden, one museum, one corridor" creates a new urban public space with themes, culture and experience; the third phase of the Pudi Water Purification Plant is a sky garden with "appearance" and "shape". The construction form of the groundwater quality purification plant is covered by a landscape park, which integrates landscape parks, sponge cities, and smart science popularization.

The person in charge of Shenzhen Huanshui Group said that next, under the guidance of the Municipal Party Committee and Municipal Government, Shenzhen Huanshui Group will accelerate the promotion of water supply and drainage management into residential communities, odor control and other livelihood projects, continue to optimize water supply and drainage services, and use Actions interpret every step, do our best, continue to meet the needs of the general public for a beautiful ecological environment, and enhance the most inclusive people's livelihood and well-being.
