Development trend of urban sewage treatment equipment

With the introduction of the "dual carbon" goals and the intensifying issue of water scarcity, urban wastewater treatment facilities are undergoing a new round of technological innovation. Future development will focus on the following directions: 1. Deepening of resource utilization: Transitioning from "wastewater treatment" to "resource recovery", equipment will not only purify wastewater but also prioritize the recovery of resources such as nitrogen and phosphorus. For instance, struvite crystallization equipment is employed to recover phosphorus from wastewater, which is then utilized to produce slow-release fertilizers. The treated reclaimed water is extensively applied in industrial production, agricultural irrigation, and urban ecological replenishment, alleviating water resource pressure. 2. Low-carbon technology upgrade: Develop low-energy consumption process equipment, such as anaerobic ammonium oxidation (ANAMMOX) equipment, which can achieve ammonia nitrogen removal without aeration, with energy consumption only being 1/10 of traditional nitrogen removal processes. At the same time, strengthen the resource utilization of sludge, reduce carbon emissions during the wastewater treatment process through biogas power generation, bio-natural gas preparation, and other methods, and promote the development of wastewater treatment plants towards a "low-carbon or even carbon-negative" direction. 3. Enhanced intelligence level: By integrating artificial intelligence (AI) technology, predictive maintenance of equipment is achieved. By analyzing equipment operation data, the risk of failure can be predicted in advance, reducing downtime. Digital twin technology is utilized to construct a virtual model of the wastewater treatment system, simulating equipment operation under different conditions, providing precise basis for process optimization. 4. Adapting to Special Water Quality Requirements: For complex water quality scenarios such as mixed treatment of industrial wastewater and domestic sewage, high-salt sewage, and refractory organic sewage, specialized and shock-resistant treatment equipment is developed, such as high-salt-resistant MBR membrane components and high-efficiency catalytic oxidation equipment, to enhance the adaptability of equipment to complex water quality.
