Project Overview

Wastewater discharged from integrated circuit manufacturing enterprises is characterised by complex composition, a wide variety of chemical substances, and difficulty in treatment, making it unsuitable for direct processing by conventional municipal water purification plants. To facilitate investment attraction in Longhua District, ease administrative supervision, and protect the ecological environment of the Guanlan River basin, it is urgently necessary to construct dedicated treatment facilities.

With the rapid development of the city, land resources in Shenzhen have become increasingly scarce. Traditional above-ground wastewater treatment plants have many drawbacks, including large land occupation, low spatial utilisation, poor landscape integration, and prominent NIMBY effects. The Zhangge Comprehensive Water Quality Purification Plant is a large-scale industrial wastewater advanced treatment facility built to support new-industry development. It has a designed daily treatment capacity of 45,000 tonnes of industrial wastewater, with effluent quality reaching the Class Ⅲ surface water standard. To solve the land-use challenge, the plant’s design abandons the traditional above-ground layout and adopts an innovative fully underground structural model. Through multiple innovative measures—such as integrated land use, ecological restoration with a rooftop park, photovoltaic energy conservation, natural lighting, and the integration of exhaust facilities with the landscape—the project upgrades a single pollution-control facility into an urban green public space that combines water purification, pollution treatment, ecological carbon sequestration, energy conservation and carbon reduction, public leisure and welfare, and landscape enhancement. It embodies the core philosophy of "Beautiful China" – “rational use of space, restoration of green ecology, and enabling a better life for people.”

Adhering to green and sustainable development, and grounded in the positioning of the pilot demonstration area of socialism with Chinese characteristics, the project is committed to building a safe, reliable, resilient, efficient, environmentally friendly, and grey‑green integrated urban wastewater system. It serves as a pilot in adapting to high-density urban development and promoting continuous improvement of the water environment, providing a Shenzhen paradigm for the sustainable wastewater system construction of megacities.

项目背景

集成电路生产企业排放废水具有成分复杂、化学物质种类多、处理难度大的特点，现有城市水质净化厂无法直接处理此类废水。为推进龙华区招商引资工作，便利行政主管部门监管，保护观澜河流域生态环境，亟需配套建设专门处理设施。

随着城市高速发展，深圳土地资源日趋稀缺，传统地面污水处理厂存在占地面积大、空间利用率低、景观融合度差、邻避效应突出等诸多短板。章阁综合水质净化厂是为新型产业配套建设的大型工业废水深度处理厂，日设计处理工业废水4.5万吨，出水达到地表Ⅲ类水标准。为破解用地难题，该厂设计摒弃传统地面厂区布局，创新采用全地下式结构建设模式，通过土地复合利用、上盖公园生态复绿、光伏节能、自然采光、排气设施与景观融合等多元创新举措，将单一治污工程升级为集净水治污、生态固碳、节能降碳、休闲惠民、景观提升于一体的城市绿色公共空间，践行美丽中国“合理利用空间、重塑绿色生态、赋能人居美好生活”的核心理念。

项目坚持绿色可持续发展，立足中国特色社会主义先行示范区建设定位，致力打造安全可靠、韧性高效、环境友好、灰绿融合的城市污水系统，在适应城市高密度发展、推动水环境持续改善方面先行先试，为超大城市可持续污水系统建设提供深圳范式。

Project Implementation

Throughout the entire process—from planning and design to construction and operation—the project has consistently adhered to the principles of intensive land use, ecology first, low‑carbon operation, and integration of landscape and treatment. Green space transformation and functional upgrading have been carried out in phases according to the construction schedule, ensuring that every stage meets the requirements of green development.

During the construction phase, the project deliberately abandoned the conventional design model of building treatment plants above ground. All wastewater treatment process units and supporting facilities were intensively integrated and arranged entirely in the underground space, maximising the saving of urban construction land. This approach eliminated visual pollution and NIMBY effects associated with traditional plants from the design source, achieving a harmonious coexistence between industrial facilities and urban space. At the same time, the underground space layout and daylighting design were optimised by installing natural light tubes on a large scale, using natural light instead of conventional artificial lighting, thereby reducing the energy consumption of the underground plant over the long-term operation and maintenance phase.

After the main structure of the plant was completed, the project fully implemented a roof greening project covering a total area of 35,000 square metres. An open urban wetland park was built in accordance with local terrain, climate, and other natural conditions, restoring and enhancing the growth conditions of regional native vegetation. This added a high-quality ecological green space to the city and increased the regional ecological carbon sink capacity. On the idle roof areas, a distributed photovoltaic power generation system was installed, utilising the unused surface resources of the plant to generate and consume clean electricity on-site, achieving self-sufficiency in clean energy. Together, these measures form a dual low‑carbon operating system combining photovoltaic energy conservation and daylighting‑based energy reduction.

In the waste gas treatment stage, the project broke away from the traditional approach of direct emission or installing conventional exhaust towers. Instead, it first subjects the production waste gas to multi‑stage deep purification until it meets the discharge standards, and then releases it through an innovatively designed landscape cloud tower exhaust system. This deeply integrates environmental treatment facilities with urban landscape design, achieving a trinity of treatment function, ecological function, and aesthetic value. It marks a comprehensive transformation of the wastewater treatment facility from a conventional "industrial plant" into an open “green public space.”

By creating a three‑dimensional composite spatial pattern of “centralised underground treatment and green park above ground,” the project effectively resolves the challenge of siting industrial support infrastructure in high‑density urban areas, enabling the synergistic development of industrial wastewater treatment functions and urban ecological service functions in the same space. The supporting intelligent operation and maintenance system is fully integrated with the HarmonyOS operating system, enabling real‑time, full‑coverage monitoring and dynamic intelligent regulation of key indicators such as influent and effluent water quality, overall plant energy consumption, and the operating status of core equipment. This ensures that the project consistently maintains efficient and low‑carbon operation. Ultimately, the project has formed an implementation pathway characterised by “spatial intensification – industrial adaptability – ecological value enhancement – public sharing,” providing a replicable and scalable mature practical model for other high‑density cities across China to treat industrial wastewater and create urban green public spaces.

Project Outcome

1. Underground intensive plant construction to alleviate urban land scarcity and NIMBY challenges

The project adopts a large-scale, fully underground wastewater treatment model, significantly saving valuable land resources in the urban core, avoiding visual disruption caused by above-ground industrial facilities, and effectively resolving NIMBY pain points such as odour nuisance, poor aesthetics, and public resistance traditionally associated with wastewater treatment plants. This achieves a harmonious coexistence between environmental infrastructure and urban communities.

2. Rooftop wetland greening to add urban green space and enhance ecological carbon sinks

The plant roof is fully greened, creating a high‑quality urban wetland park of approximately 35,000 square metres, which greatly increases regional green coverage. The park’s robust vegetation forms a stable ecological carbon pool, with an average annual carbon sequestration of about 80 tonnes, filling the gap in urban ecological space while providing an open leisure area for the public.

3. Dual empowerment of photovoltaics + natural daylighting for comprehensive energy conservation and low‑carbon operation

Multiple underground daylight tubes are innovatively installed to maximise the intake of natural light, reducing year-round lighting electricity consumption in the underground plant. A rooftop photovoltaic power system is also deployed to enable self-generation and self-consumption of clean electricity. Together, these form a dual low-carbon operation and maintenance model—"natural light + new energy"—continuously reducing the project’s carbon emissions and operational energy use, with annual electricity savings of approximately 360,000 kWh.

4. Landscape-integrated waste gas treatment to create a landmark of high aesthetic and ecological value

After deep purification to meet emission standards, the waste gas is discharged through a distinctive landscape cloud tower, transforming functional environmental facilities into urban landscape features. This delivers multiple benefits including compliance with pollution control requirements, environmental friendliness, and enhanced landscape quality.

5. AI-empowered HarmonyOS foundation to ensure stable effluent quality and precise consumption control

Using the HarmonyOS system as the digital foundation, integrated with AI algorithms, IoT sensing, and intelligent early‑warning mechanisms, the project builds a “cloud‑edge‑device” integrated architecture that overcomes the common issues of scattered equipment and data silos in traditional plants. It enables device interconnection, data sharing, and intelligent coordination. Through AI model‑based predictive analysis of influent water quality and treatment processes, parameters are automatically adjusted to achieve precise chemical dosing and intelligent aeration, ensuring stable effluent quality while reducing chemical and energy consumption.
