What Are the Different Wastewater Treatment Jobs?

Wastewater treatment methods use physical, chemical, and biological methods to treat wastewater to purify it and reduce pollution, so as to achieve wastewater recovery and reuse, and make full use of water resources.

Adopt reasonable

According to the degree of treatment, wastewater treatment (mainly urban sewage and some

The pretreatment process used by the pretreatment unit for municipal wastewater can include:

Historically, wastewater has been viewed as a harmful thing that needs to be disposed of in the cheapest and least environmentally friendly way possible. This means that on-site disposal systems, such as wastewater from latrines, can be discharged directly into rivers and lakes. Over the past century, these methods have been recognized to have a negative impact on the environment. This has led to the development of a variety of treatment technologies, such as today's municipal wastewater treatment systems. If we look ahead, for economic benefits and sustainable development, we must treat wastewater as a raw material. Clean water is becoming scarce, so wastewater should be treated and reused. The rich nutrients in wastewater, such as nitrogen and phosphorus, are recovered and used to grow crops in some treatment processes. To achieve a sustainable future, we must increasingly use this approach, working to improve energy efficiency in wastewater. ^[4]
