Tech Integration & Dual-Carbon Empowerment — The 2026 National Water Technology Conference & Equipment Exhibition Grandly Opens in Hangzhou, China

As a "Low-Carbon Pioneer" in rural wastewater treatment, Denggao Environmental Technology Co., Ltd. ("Denggao") made a significant impact at the event. The company showcased its headline technology: "Low-Carbon Fractional Treatment Technology for Rural Domestic Wastewater in Water Network/Hilly Areas." At the conference, Denggao Environmental joined environmental regulators, industry experts, and peers from across the nation to explore new pathways for water governance.

Mr. Deng Xu, Chairman of Denggao Environmental, attended the opening ceremony of the 2026 National Water Technology Conference & Equipment Exhibition. He listened attentively to keynote reports delivered by senior industry leaders and authoritative experts in water environment governance.

Live Expo Highlights: Non-Powered Processes Spark Enthusiasm

During the exhibition, the Denggao Environmental booth drew massive crowds. Led by Chairman Mr. Deng Xu, the team engaged in in-depth discussions with guests regarding the logic of "Non-Powered + Resource Recovery":

Addressing industry pain points such as "high electricity costs, expensive maintenance, difficult pipe network installation, and resource waste," they proposed a solution featuring "Zero Electricity Throughout & Localized Resource Recovery."

The displayed process models attracted numerous attendees for consultations, with many organizations expressing intent for site visits.

Keynote Speech: Authoritative Forum Decodes Technical Core

On May 21, Technical Director Mr. Zuo Zengde took the stage at the "5th Forum on Village and Town Water Environment Governance and Industrial Innovation Development" (Session VI). He delivered a keynote speech titled Transformation and Promotion of Low-Carbon Fractional Treatment Technology for Rural Domestic Wastewater in Water Network/Hilly Areas, igniting enthusiastic discussion.

Key highlights of the speech included:

●Breaking Industry Deadlocks:

◇Economic Dilemma: Powered processes suffer from high electricity/maintenance costs, leading to facilities being "left idle" (abandoned).

◇Engineering Dilemma: Difficulties in laying centralized pipe networks in water network/hilly areas lead to "maladaptation".

◇Resource Dilemma: Direct sewage discharge damages ecosystems, wasting valuable nutrients.

●Technology Principle Breakdown:

◇Gravity-Driven Flow: Zero electricity consumption throughout, relying on natural elevation differences for self-flowing sewage, fundamentally solving the problem of "unaffordability".

◇Multi-Stage Enhanced Anaerobic Tank: Equipped with low-temperature resistant composite bio-bacterial strains + bio-filter media, achieving ≥98% removal rates for fecal coliforms and helminth eggs.

◇Multi-Functional Deep Filter Tank: Specialized filter media for ammonia nitrogen and phosphorus removal, achieving ≥95% removal rates.

◇Ecological Resource Pool: Effluent is directly usable for farmland irrigation or landscape replenishment, or converted into liquid organic fertilizer for return to fields, realizing a "Sewage → Resource" closed loop.

●Scenario-Based Solutions:

For complex terrains like dense water networks and rolling hills, four process matrices were introduced: "Decentralized (Single Household), Modular (Cluster/Rural Tourism), Integrated (Centralized Treatment), and Mountain Mode (Diversion Ditch + Bio-Culture)," adaptable to diverse rural scenarios.

Successful Conclusion: Lively Exchange Leads to Flood of Cooperation Intent

Throughout the exhibition, the Denggao team held deep exchanges with numerous delegates. Regulatory authorities and environmental enterprises from multiple regions expressed immediate strong intentions for "site visits and project cooperation".

From technical presentations to case studies, from booth interactions to special speeches, Denggao delivered an impressive answer sheet at the National Water Technology Conference with its "Non-Powered, Low-Carbon, Resource Recovery" water treatment solutions.

As the "Dual-Carbon" strategy advances, rural wastewater treatment is upgrading from focusing on "existence" to prioritizing "quality and cost-effectiveness." Denggao will continue to practice the philosophy of "Fractional Treatment, Low-Carbon Cycle, and Local Resource Recovery", enabling more villages to adopt water treatment solutions that are "Affordable to Build, Affordable to Use, and Easy to Manage", thereby contributing to rural revitalization and green development!
