How to achieve green and low-carbon development of sewage treatment?

Drainage pumping stations are also big energy users. Some data show that drainage pumping stations account for 35% of the total energy consumption of urban water. Therefore, upgrading the drainage pumping station or adopting intelligent operation mode can effectively reduce energy consumption.

At present, there are two main methods, one is to use frequency conversion technology to transform old drainage pump stations, or new projects directly use digital pumps and other new equipment and facilities, in order to reduce the energy consumption of pump stations.

Secondly, from the perspective of the system, the operation mode of the drainage pumping station is optimized from a higher level. On this basis, the Internet of Things and mobile Internet technology are used to create an intelligent management platform to achieve remote control, centralized management and digital operation of drainage pumping stations, so as to achieve the purpose of energy saving and consumption reduction.

In general, achieving carbon neutrality in the wastewater treatment industry is a long-term systematic project.

Only from the perspective of the sewage treatment plant industry, it is necessary to systematically plan the whole process of "user control - source separation - pipe network storage - purification treatment".

In this process, the relevant government departments and enterprises need to comprehensively upgrade the management and operation mode, upgrade from management-driven to data-driven, build a new digital management model, and realize the intelligent upgrade of the entire operation model.

To fundamentally solve this problem, we need to jump out of the sewage treatment industry, stand in the ecological civilization construction, urban and rural integration development, sewage resources, energy self-sufficiency, environmental friendliness and other aspects of comprehensive consideration, need to carry out top-level planning, system design and overall arrangement from the different levels of "point-line-face-body".

This is not only a technological and conceptual renewal of the entire industry, but also a revolution in the thinking and cognition of the entire society.

It will be a long and tortuous process. It is encouraging that the proposal and practice of the wastewater treatment concept plant has taken a critical first step, and we have reason to believe that China's wastewater treatment industry will soon make a positive contribution to the carbon neutral strategy.
