（五）减污降碳协同。采用节水减污和温室气体减排协同控制等技术工艺，推动不同水质特点废水协同处理，减少废水排放量。探索工业废水循环利用与可再生能源利用相结合，全流程开展减污降碳协同增效。

内容提到，申报主体为具有独立法人资格的用水企业（数据中心）或具备统一管理机构的省级以上工业园区。鼓励废水循环利用技术、工艺和装备服务商与应用单位联合申报。

It is pointed out that the collection direction of typical cases of industrial wastewater recycling in 2024 will focus on key industries such as steel, petrochemical, chemical, textile, paper, food, and key areas such as data centers, and collect a batch of typical cases of wastewater recycling for industrial enterprises and parks.

Includes:

(1) Cycle of water use process. The high efficiency recycling of cooling water, the separation of water in the production process, the deep treatment and reuse of wastewater and other technical equipment are adopted to reduce the water consumption in the production process, realize the series water, the multi-purpose of one water and the cascade utilization, and improve the reuse rate of water.

(2) Regional integration of industry and city. Explore cooperation with municipal reclaimed water production and operation units to improve the reclaimed water pipe network, return the reclaimed water after treatment to the production process, reduce the amount of new water consumption, and form a new model of efficient recycling of wastewater from the integration of industry and city that can be replicated and promoted.

(3) Smart water control. New generation information technologies such as big data, cloud computing, and the Internet will be used to establish a smart management and control platform for industrial wastewater recycling, form capabilities such as perception, monitoring, early warning, and emergency response, and improve the level of digital management, network collaboration, and intelligent management and control of industrial wastewater recycling.

4. Innovation in technology and equipment. Focusing on the blocking points and difficulties in the whole process of industrial wastewater recycling, we will strengthen collaborative research and development, innovate and develop low-cost and high-performance industrial wastewater recycling equipment technologies and processes, and create demonstration models of collaborative efforts in industrial wastewater recycling technology, engineering and services.

(5) Coordination in reducing pollution and carbon. Technologies such as water saving and pollution reduction and greenhouse gas emission reduction are adopted to promote the collaborative treatment of wastewater with different water quality characteristics and reduce the discharge of wastewater. Explore the combination of industrial wastewater recycling and renewable energy utilization, and carry out synergies in reducing pollution and carbon in the whole process.

The content mentions that the subject of the declaration is a water enterprise with independent legal personality (data center) or an industrial park above the provincial level with a unified management organization. Encourage waste water recycling technology, process and equipment service providers and application units to jointly declare.
