Recently, the China Environmental Protection Industry Association officially released the “2025 Catalog of Practical Technologies and Typical Projects for Ecological and Environmental Protection,” aiming to accelerate the promotion and application of advanced, practical, and green technologies and equipment as well as typical projects, foster new productive forces in the ecological and environmental protection industry, support the in-depth and effective fight to safeguard “blue skies, clear waters, and clean soil,” and contribute to the green, low-carbon, and high-quality development of the economy and society.
Beijing BHT Environmental Technology Co., Ltd. has successfully been included in this list thanks to its continuous innovation and practical engineering experience in the field of wastewater treatment. The company’s three core technologies—its independently developed BioDopp micro-oxygen biochemical process, the BioComb integrated decentralized wastewater treatment device, and the BMR prefabricated integrated system—clearly demonstrate the company’s leading expertise and industry influence in the field of ecological and environmental protection technology.
BioDopp Micro-Oxygen Biochemical Process: Highly Efficient and Energy-Saving, Pioneering a New Paradigm for Low-Carbon Water Treatment.
As a core patented technology of BHT, the BioDopp process achieves simultaneous nitrification and denitrification along with biological phosphorus removal by controlling a micro-oxic environment. This process integrates the advantages of full-liquid internal reflux in oxidation ditches, functional zoning in the A²/O process, and a CASS pre-selection zone. It features a 40% reduction in land footprint, more than a 40% decrease in aeration energy consumption, and strong resistance to shock loads. As a result, it offers significant advantages in the treatment of high-concentration, difficult-to-degrade industrial wastewater as well as municipal wastewater treatment applications.
As of now, the BioDopp industry has an annual capacity of nearly 3 million tons per day. In the sub-sector of microaerobic processes, it has become the process with the highest global market share, the deepest level of industrialization, and the broadest industry coverage.
BioComb Integrated Decentralized Wastewater Treatment System: Flexible Adaptation, Empowering Rural and Remote Areas
For decentralized wastewater treatment scenarios such as rural areas, tourist attractions, and highway service areas, BHT has launched the BioComb integrated unit—a device that combines biochemical reaction, sedimentation, filtration, and disinfection in a single compact unit. It boasts advantages including reliable quality, intelligent operation and maintenance, and stable effluent quality that consistently meets standards. Over 800 sets of BioComb integrated units have already been put into operation, supporting more than 100 wastewater treatment projects across 20 provincial-level administrative regions nationwide, as well as overseas markets including the United Arab Emirates and Mongolia. This innovative solution effectively addresses the challenges of treating small-scale, highly variable wastewater, providing dependable equipment support for improving living environments.
BMR Prefabricated Integrated System: Modular Construction, Setting a New Benchmark for Emerging Engineering
The BMR prefabricated integrated system adopts a factory-prefabrication and on-site assembly approach, significantly shortening the construction period and reducing construction disruptions, thus aligning with the green building concept under the “dual-carbon” goals. The system can flexibly combine processes according to water quality and quantity, making it suitable for various scenarios such as emergency response and temporary capacity expansion. It also features standardization, long service life, and high cost-effectiveness.
The simultaneous inclusion of these three technologies in the authoritative list is a high-level recognition of BHT’s long-term commitment to technological innovation. BHT will continue to deepen its expertise in wastewater treatment, accelerate the commercialization of scientific and technological achievements, and provide more “advanced, practical, and environmentally friendly” technological equipment to support the country’s ecological civilization development, thus contributing to the construction of a modern society where humans and nature coexist harmoniously!
