Beijing Tongzhou Water Bureau | Hedong Resource Recycling Center Phase I Project officially put into operation in June

Recently, the first phase of the Hedong Resource Recycling Center project has successfully completed single machine and linkage debugging, and the equipment has reached the design processing capacity. It is expected to officially start water supply operation next month.

Entering the first phase of the Hedong Resource Recycling Center project adjacent to the Grand Canal, a large green carpet laid on the lawn comes into view. The factory covers an area of approximately 2.7 hectares, with a designed processing capacity of 60000 tons per day. After the project is put into operation, it will be combined with the existing Hedong Reclaimed Water Plant to form a total processing capacity of 108000 tons per day, meeting the needs of sewage treatment, reclaimed water utilization, and sludge treatment in the eastern part of Beijing's urban sub center.

Project highlights

Adopting a distributed underground reclaimedwater ecosystem

The system consists of ten major technologies, including a flexible and efficient bioreactor, a "fresh" multi-dimensional air constant purification system, and a "cloud based" intelligent control system. Using urban sewage as the second stable water resource, second green energy, and second land resource of the city, we aim to create a distributedunderground reclaimedwater ecosystem that integrates factories, networks, rivers, water, land, and ecological systems, and integrates carbon, energy, and quality. In order to avoid the impact on the surrounding environment, the deodorization process of the project has become the design focus of the overall project. The odor from each area is collected and transported to the biological deodorization reactor through pipelines, and the pollutants in the gas are subjected to contact reactions through enriched biological colonies, ultimately achieving standard emissions.

Advanced design concept for recycled water reuse

At the beginning of the design, the amount of recycled water used outside the factory was considered, and sufficient clean water tanks and distribution pumps were reserved inside the factory to ensure that the recycled water system would be put into use immediately after the project was completed. The regenerated water outside the factory is used for water supply in the municipal government office area, ecological water replenishment in Jinghu Lake, landscaping water, and cooling water for energy production; The recycled water in the factory is mainly used for production water, ecological greening, etc., with a 100% reuse rate of recycled water.

Advanced smart water management platform

After adopting the smart water management platform, on the one hand, the data monitoring and analysis system can optimize drug consumption, energy, and personnel configuration, reducing operating costs; On the other hand, by configuring "robots" for inspection, the workload of operation and maintenance personnel can be reduced, occupational safety hazards can be reduced, personal safety can be improved, and problems can be detected and solved in a timely manner through "robots", thereby improving the safety of the sewage treatment system.

Energy saving optical lighting system

Due to poor lighting, underground sewage treatment plants often have multiple lighting systems and consume a large amount of electricity. In this project, a light guiding lighting system is installed to fully utilize sunlight sources, reduce the energy consumption of underground plant lighting, improve operational comfort, and respond to the national "dual carbon" goal.

At present, the project has completed completion acceptance and is scheduled to enter the commercial operation stage in early June. After the project is put into use, it will be the largest resource recycling center in the eastern part of the urban sub center, playing a very important role in protecting the natural environment of the urban sub center, improving the living environment of residents, promoting economic development, improving residents' living standards, and developing circular economy.
