Group 1: Professional Background and Achievements - He Xiaotian began his career in 2011 at the Ma Taogang Wastewater Treatment Plant, gaining extensive experience in wastewater treatment [2]. - He won first place in the national "Drainage Cup" skills competition with zero errors, showcasing his expertise [2]. - He has received multiple honors, including National Labor Model and National May Day Labor Medal, for his outstanding work [1]. Group 2: Technological Innovations - He led the development of precise aeration and dosing technologies, filling a technological gap in Henan's wastewater treatment industry [2][4]. - The team created a photovoltaic-driven cleaning robot for secondary sedimentation tanks, transitioning from manual to intelligent operations [3]. - The workshop has accumulated 13 national invention patents, 81 utility model patents, and 20 software copyrights, generating over 20 million yuan in economic benefits [4]. Group 3: Training and Knowledge Dissemination - He has compiled practical experience into training materials, which have become standard textbooks for the wastewater treatment industry in Henan [5]. - His advocacy led to the inclusion of wastewater treatment as a category in national skills competitions, opening new pathways for talent development [5]. - Hundreds of skilled technicians have emerged from his innovation studio, contributing to the sustainable development of Henan's wastewater treatment sector [5]. Group 4: Environmental Impact - The Ma Taogang Wastewater Treatment Plant processes 600,000 tons of water daily, contributing to the ecological health of the region [5]. - The treated water is utilized for various purposes, including cooling for power plants and as a water source for central air conditioning systems [5].

Core Viewpoint - The water and environmental protection industry is leveraging technological innovation to promote intelligent, resource-efficient, and low-carbon water environment governance, contributing to sustainable development and water resource protection through initiatives like "Beijing Water Solutions" [1][9]. Group 1: Smart Water Treatment Operations - North Control Water integrates digital technology with wastewater treatment, achieving high-quality automated operations without manual intervention, significantly improving operational efficiency [1][3]. - Emergency response instances at the Taziba Wastewater Treatment Plant have decreased from 23 times per month to 1-2 times, and equipment control rates have increased from 54% to 86%, ensuring stable and efficient operations [3]. Group 2: Reclaimed Water Initiatives - The Yinchuan First Reclaimed Water Plant, the largest in Northwest China, features a garden-style design that integrates recreational spaces with wastewater treatment, promoting environmental harmony and urban development [5]. - The park utilizes reclaimed water for irrigation, demonstrating a successful model of co-existence between environmental sustainability and urban growth [5]. Group 3: Low-Carbon Technology Advancements - The BE-Fenton advanced oxidation process, combined with an automated dosing control system, has been implemented in multiple projects, achieving a COD removal rate of 40%-60% and reducing operational costs by 30%-50% [5]. - This technology is applied in six projects with a total design capacity of 145,500 cubic meters per day, potentially reducing difficult-to-degrade COD by approximately 2,610 tons per year [5]. Group 4: Clean Energy Utilization - North Control Water has installed distributed photovoltaic power generation systems on water plant rooftops, replacing traditional fuel with clean energy, with nearly 50 plants adopting this technology and a total installed capacity exceeding 160 megawatts [7]. Group 5: Future Water Management Strategies - The "Future New Water Development Report" proposes a strategy for coastal seawater desalination, aiming to establish a short-distance water cycle centered on desalination within 100 kilometers of the coast [8][9]. - The report emphasizes the need for industrial policies to promote desalination development, as China's current desalination capacity accounts for only 3% of the global total, which is inadequate given the country's water scarcity [9].
