Historically, wastewater has been regarded as a harmful thing and needs to be disposed of in the cheapest way possible without affecting the environment. This means that on-site disposal systems can be used, such as the waste water generated by the latrines, directly discharged into rivers and lakes. In the past century, people have recognized that these methods have an adverse effect on the environment. This has led people to develop a variety of treatment technologies, such as today's urban wastewater treatment systems. If we look forward, for economic benefit and sustainable development, we must treat wastewater as a raw material. Clean water is becoming more and more scarce, so wastewater should be treated and reused. The rich nutrients in wastewater, such as nitrogen and phosphorus, are recycled and used to grow crops in certain treatment processes. In order to achieve a sustainable future, we must use this method more and more, working to improve the energy efficiency of wastewater.
