1.Characteristic water utilities technology
（1）Construction of ecological water plant
In combination with the natural conditions, production characteristics and layout plan of the water utilities enterprise, the system ecological development is carried out through the optimization of process structures, apportioning and planting of plants, landscape artistic creation, leisure facilities and auxiliary facilities to build a composite artificial ecosystem, realize the functions of beautifying the environment, deodorizing and reducing noise, improve the ecological environment of the plant area, and establish a good corporate image.
（2）Comprehensive treatment of rural water environment
Mature sewage treatment process is adopted to establish individualized sewage treatment module. By changing the different combinations of various process modules, different sewage quality can be adapted to give play to the advantages of different processes, so as to achieve high sewage collection rate, stable process, less land occupation and low operating cost, and thus improve the rural water environment.
（3）Smart construction of water utilities
The management platform based on the Internet of Things and cloud computing provides a unified business information management platform for the safety management, production operation, water quality testing, equipment management, daily office work, etc. of various water treatment operations, and conducts centralized management, statistical analysis, and data mining of enterprise real-time production data, video monitoring data, process design, daily management and other related data, providing instant & rich production and operation information for production and operation managers at different levels, lay good foundation for supporting analysis and decision-making, and provide strong technical support for standardized management, energy conservation and consumption reduction, staff reduction and efficiency enhancement, and refined management of enterprises.
（4）Clean energy for water utilities
Clean energy construction of photovoltaic power generation will be carried out above the water enterprises' workshops, roads and pools, giving full play to the industrial policy and mode of "self-power generation for self-use, excess electricity connecting to power grid ", boosting energy conservation and consumption reduction of water enterprises, and accelerating the development of new energy industry.
（5）Recycling of reclaimed water and zero discharge of waste water
In the fields of industrial wastewater recycling and zero discharge, advanced treatment and zero discharge of DeSOx wastewater, concentration and recycling of high salinity wastewater, harmless treatment of landfill leachate and etc., membrane treatment, electrodialysis and evaporative crystallization processes are fully used to fully recycle production wastewater, and salt in water is recycled and harmlessly treated
2. Intellectualizing: smart pipe gallery & smart water utilities
Smart pipe gallery: with the management guideline of "acknowledging, controlling, alerting, deciding, managing, operating and sharing", supported by big data, Internet of Things, cloud architecture, intelligent configuration, comprehensive business decision analysis, artificial intelligence and other technologies, combined with urban geographic information system (GIS) and building information model (BIM), and by integrating various data analysis, comprehensive management platform for pipe gallery operation with unified command, complete functions, sensitive response and efficient operation is built, which includes 1 center, 1 platform, 7 application systems, and N nos. of terminals to conduct real-time monitoring, operation management, and safety forewarning for the environment, equipment, and operation in the integrated pipe gallery, improve the efficiency of decision-making and command, and effectively improve the ability to deal with security emergency, so as to ensure the safe and efficient operation of the system.
Smart water utilities: based on geographic information system (GIS), Internet of Things and cloud computing technology, build smart sewage system platform, provide a unified business information management platform for key businesses such as safety management, production operation, water quality testing, equipment management and daily office work of sewage operation enterprises, and conduct centralized management, statistical analysis and data mining for enterprise real-time production data, video monitoring data, process design, daily management and other relevant data, provide instant & rich production and operation information for production and operation managers at different levels, lay good foundation for supporting analysis and decision-making, and provides strong technical support for standardized management, energy conservation and consumption reduction, staff reduction and efficiency enhancement, and refined management of enterprises.
3. Building: concealed beam fabricated steel structure building integrated system
Concealed beam fabricated steel structure building integrated system: taking building function as the core, structural layout as the basis, industrialized enclosure, internal installation and equipment pipeline components as the support, and comprehensively considering the coordination and integration of building layout, external facade, structural system, enclosure structure, equipment pipeline, component protection, internal installation and other aspects, it realizes the coordination of main steel structure system, peripheral enclosure system, equipment pipeline system, internal installation system, the steel beam is concealed in the floor or wall to avoid the impact of the exposed steel structure on the use function, which solves the anti-corrosion and fire protection problems of the steel structure, and also gives play to the advantages of the fabricated steel structure building in the flexible partitioning of large spaces.
4. Energy sources: comprehensive development and utilization of by-product hydrogen energy
The crude hydrogen in the by-products of the metallurgical industry and chemical industry is used as the hydrogen source for fuel cell vehicles after refining processes such as DeSOx, pressure swing adsorption and cryogenic separation. SDM is committed to the production, storage & transportation of by-product hydrogen and the comprehensive development and utilization of hydrogen energy such as hydrogen short process ironmaking, providing full process support for the national hydrogen energy development and utilization.
