Wastewater Treatment for Environmental Sustainability

Abstract

Environmental sustainability is the result of a set of actions carried out within the framework of Sustainable Development Goals to effectively use natural resources, protect nature, eliminate damage, prevent harmful processes such as pollution, greenhouse effect, and leave a cleaner nature for both current and future generations. Pollution is one of the main causes of environmental damage. Pollution of land, water, and air with various substances and materials has a negative effect on nature, and then on all living beings, causes the emergence, spread, and increase of diseases. In the ranking, the biggest pollution is air, then water, and lastly soil pollution. Water pollution, which ranks second, damages the environment at least as much as air pollution, causing the emergence and spread of diseases. Various technologies are used to ensure environmental sustainability. These technologies are mainly referred to as green technologies and are known as eco-friendly technologies. Green technologies are applied for various purposes. Such technologies are also applied to pollution prevention. In this chapter, wastewater treatment to ensure environmental sustainability and the technologies considered for this are considered in a theoretical form. In the end, as a practical part, the issue of phenol decomposition with the participation of UV radiation in wastewater treatment was considered.
