With the rapid development of society, industrialization and urbanization, the problem of water pollution has become increasingly serious, which has become one of the important factors restricting sustainable development. Therefore, it has become a global consensus and action to strengthen sewage treatment and improve the recycling rate of water resources. In this context, the sewage treatment technology under the advantage of environmental protection shows its unique characteristics, which not only effectively relieves the environmental pollution problem, but also creates a more livable living environment for human beings.

1. Efficiency

Modern sewage treatment technology greatly improves the treatment efficiency by adopting advanced biological treatment, physical and chemical methods and membrane separation technologies. For example, MBR (Membrane Bioreactor) technology combines the advantages of traditional activated sludge process and membrane filtration, and realizes sludge-water separation while removing pollutants, which has the characteristics of good effluent quality, small floor space and low operating cost.

2. Environment-friendly

The sewage treatment technology developed under the advantage of environmental protection pays attention to the protection of natural ecosystem, and strives to achieve "zero discharge" or minimize the impact on the outside world. For example, using wetland system for natural purification is a good example. It can not only effectively degrade nutrients such as organic matter, nitrogen and phosphorus, but also provide habitats for animals and plants and promote the development of biodiversity.

3. Resource recovery and reuse

With the popularization of the concept of circular economy and the progress of technology, more and more sewage treatment plants begin to explore the recovery of valuable resources from wastewater, such as reclaimed water reuse and biomass energy development. These measures can not only reduce the pressure on the demand for fresh water, but also produce economic and social benefits.

4. Intelligent management

With the help of information technology such as Internet of Things and big data analysis, the sewage treatment process has become more intelligent and accurate. By monitoring the change of water quality in real time and automatically adjusting the process parameters, the treatment effect can be ensured to be stable and reliable; At the same time, it can also find potential faults in time and reduce maintenance costs.

In a word, in the process of pursuing the balance between environmental protection and economic development, sewage treatment technology with high efficiency, environmental protection, resource saving and intelligent management plays an irreplaceable role. future, with the continuous progress of science and technology and the change of social demand, this field will usher in more opportunities for innovation and development.
