In the context of increasingly severe global water scarcity and pollution, integrated sewage treatment equipment has become a core issue for ecological environment protection and sustainable development. Integrated sewage treatment equipment, with its core advantages of integration, modularity, and high efficiency, effectively addresses the pain points of traditional sewage treatment systems such as large footprint, long construction period, and complex operation and maintenance. It has been widely used in various scenarios such as municipal, industrial, and rural areas. Relying on policy driven, technological iteration, and demand upgrading, its market application prospects continue to improve, while also facing challenges such as standardization and funding guarantee. The industry is moving towards a new stage of high-quality development. 1、 The market size of integrated sewage treatment equipment continues to expand, with strong growth momentum The global and Chinese integrated sewage treatment equipment markets are both in a high-speed growth channel, driven by both policy support and demand release. From a global market perspective, the market size has reached approximately $20 billion by 2024 and is expected to exceed $35 billion by 2030, with a compound annual growth rate of over 8%. The Asia Pacific region, with its rapid infrastructure construction and population agglomeration effect, holds over 45% of the global market share and has become a core growth pole. The performance of the Chinese market is particularly outstanding, with a market size exceeding 50 billion yuan in 2024 and expected to reach 18 billion yuan in 2025 (according to segmented statistical standards), with a compound annual growth rate of about 12.5%. It is expected that the market size will approach 90 billion yuan by 2030, with sufficient long-term growth resilience. The main driving force for growth comes from three aspects: firstly, policy enforcement, with countries raising their sewage discharge standards one after another. China has introduced policies such as the "Action Plan for Water Pollution Prevention and Control" and the "Plan for Urban Sewage Treatment and Resource Utilization", which explicitly require the national urban sewage treatment capacity to be increased to over 260 million cubic meters per day by 2025, and the harmless disposal rate of sludge in prefecture level and above cities to reach 90%, promoting the intensive implementation of new construction and upgrading projects; Secondly, urbanization and rural revitalization are accelerating, with continuous growth in urban sewage discharge and explosive demand for decentralized sewage treatment in rural areas, providing vast incremental space for integrated equipment; The third is the upgrading of industrial environmental protection needs, with industries such as chemical, papermaking, food processing, and medical industries increasing their requirements for fine and standardized wastewater treatment, which has spurred the demand for customized equipment. 2、 The application scenarios of integrated sewage treatment equipment are constantly expanding, and the potential of segmented fields is highlighted Driven by the adaptability advantages of integrated sewage treatment equipment, the application scenarios have extended from traditional municipal fields to multiple fields such as industry, rural areas, and public facilities, presenting diversified and refined development characteristics. （1） Integrated sewage treatment equipment for municipal sewage treatment: stable demand, resource utilization becomes mainstream Municipal sewage treatment remains the largest application area, with an estimated market size of 10 billion yuan by 2025, accounting for 55% of the total national market. With the transformation from "standard emissions" to "resource utilization", integrated equipment is gradually replacing traditional facilities, especially in urban new areas and old city renovation projects. With underground and compact design, it can effectively save land resources. For example, the resource utilization project of Beijing Bishuiyuan's sewage treatment plant in Miyun District adopts MBR membrane bioreactor+reverse osmosis technology, and the effluent can be directly used for municipal greening, with an annual resource utilization of 18.25 million cubic meters, alleviating the regional water shortage problem. In the future, the municipal sector will focus on promoting the reuse of recycled water and the resource utilization of sludge, and the market share of intelligent integrated equipment will continue to increase. （2） Integrated sewage treatment equipment for rural areas and decentralized sewage treatment: incremental core, concentrated release of policy dividends Rural sewage has the characteristics of strong dispersion, large fluctuations in water volume, and difficulty in laying pipeline networks. Traditional centralized treatment systems are difficult to adapt to, and integrated equipment has become the core solution to solve the problem of direct discharge of rural sewage. With the continuous promotion of the rural revitalization strategy and the rural living environment improvement action, the rural sewage treatment market is experiencing explosive growth, and the market size is expected to reach 3 billion yuan by 2025. This type of scenario requires high modularity, low cost, and easy operation and maintenance characteristics of the equipment. Companies such as Sande Environment have launched modular assembly equipment, which can reduce construction costs and land occupation, and meet the needs of rural sewage treatment. In addition, emerging scenarios such as rural tourism and characteristic towns have also spurred the demand for small-scale integrated equipment, further expanding market boundaries. （3） Integrated sewage treatment equipment for industrial wastewater treatment: strong demand for customization, significant growth in segmented industries The industrial wastewater treatment market is expected to reach a scale of 5 billion yuan by 2025, with demand mainly coming from industries such as chemical, papermaking, food processing, slaughtering, and medical. There are significant differences in wastewater quality among different industries, such as medical wastewater containing pathogens, aquaculture wastewater with high ammonia nitrogen concentration, and chemical wastewater containing difficult to degrade organic matter, which require extremely high customization of equipment processes. Integrated equipment can serve as a pre-treatment unit for enterprises, reducing centralized processing pressure or directly achieving standard discharge. For example, the equipment customized by Shandong Donghai Ge Environmental Protection for Ningjin County People's Hospital in Dezhou achieves a pathogen removal rate of 99.99% through the process of "biochemical treatment+ultraviolet disinfection+online monitoring", meeting the new version of medical wastewater discharge standards. In the future, with the increasing pressure of environmental compliance in industrial enterprises, the demand for integrated equipment in the field of high concentration organic wastewater and difficult to degrade wastewater treatment will grow rapidly. （4） Integrated sewage treatment equipment, public facilities and special scenarios: precise adaptation, steadily increasing demand The sewage discharge of public facilities such as high-speed service areas, scenic spots, airports, and stations is stable, and there are strict requirements for equipment footprint and operating noise. The compact and low-noise advantages of integrated equipment can be perfectly adapted. In addition, emergency sewage treatment scenarios such as sudden water pollution incidents and temporary engineering projects require increased mobility and rapid deployment capabilities of integrated equipment, further expanding the breadth of application scenarios. 3、 Technological iteration leads the upgrade, and the core direction is towards intelligence and resource utilization Technological innovation is the core driving force for upgrading the integrated sewage treatment equipment market. Currently, the industry is iterating towards intelligence, automation, resource utilization, and energy conservation, and product competitiveness continues to improve. In terms of core technologies, MBR (membrane bioreactor), MBBR (moving bed biofilm reactor), SBR (sequencing batch reactor) and other processes dominate the market, and domestic enterprises' technological strength continues to break through. The MBR membrane module of Beijing Bishuiyuan has a retention accuracy of 0.01 microns, and the service life of membrane materials is extended by 20% compared to industry standards; Pioneering the development of the "sewage sludge biogas" resource utilization industry chain for environmental protection, the biogas produced by anaerobic digestion of sludge can achieve a project energy self-sufficiency rate of 30%, and the related technology has won the second prize of National Science and Technology Progress Award. At the same time, patent applications in fields such as high-efficiency membrane materials, low-energy aeration technology, and sludge reduction technology continue to grow, and technological barriers are constantly increasing. The acceleration of intelligent transformation has become an industry consensus, with the deep integration of IoT, big data, and artificial intelligence technologies and devices to achieve remote monitoring, intelligent adjustment, fault warning, and energy consumption optimization. The intelligent water integration technology of Beikong Water can adjust the aeration intensity and dosage of chemicals in real time through online monitoring and AI algorithms, improving the efficiency of nitrogen and phosphorus removal by more than 25% and significantly reducing operation and maintenance costs. In the future, intelligent operation and digital management will become the core competitive advantages of enterprises, driving the industry's transformation from "equipment sales" to "full lifecycle services".
