In view of the complexity of the nature of wastewater, it is necessary to promote more advanced wastewater treatment technologies, including reverse osmosis, bioreactors, ultraviolet disinfection and other technologies. These technologies can effectively remove harmful components from wastewater and meet the strict standards required for wastewater discharge.
To address the high cost of wastewater treatment, improvements need to be made in terms of resource utilization, management and operation. The cost of wastewater treatment can be reduced by improving operational efficiency, energy-saving and consumption-reducing technologies, and ecological construction.
In order to protect the environment and human health, it is necessary to improve the relevant wastewater discharge standards, and in the process of standardization, different discharge standards are formulated according to the nature of different wastewater to ensure the safety and environmental friendliness of discharged wastewater.
Wastewater treatment is an important means to protect the environment and human health, but it also needs to face many challenges. By promoting advanced wastewater treatment technologies, reducing the cost of wastewater treatment and improving wastewater discharge standards, we can more effectively meet the challenges of wastewater treatment and reach the goal of environmentally sustainable use of water resources.
