Domestic sewage, if discharged directly without treatment, will cause great harm to the environment. Organic matter, nitrogen, phosphorus and other pollutants in sewage will cause eutrophication of water bodies and affect the survival of aquatic organisms.
Just like Shi Zhiyong's unremitting efforts on the field, the R&D and operation personnel of domestic sewage treatment equipment are also silently contributing. They continuously improve technology and improve treatment efficiency to reduce the damage of sewage to the environment.
In the process of domestic sewage treatment, a variety of methods and technologies are used. Common ones include physical treatment, chemical treatment and biological treatment. Physical treatment removes suspended matter in sewage through sedimentation, filtration and other methods; chemical treatment uses chemical reactions to remove pollutants; biological treatment relies on the metabolism of microorganisms to decompose organic matter.
This is just like Shi Zhiyong constantly adjusting his strategies and skills during the competition to cope with various challenges.
The operation of domestic sewage treatment equipment consumes a lot of energy and resources. In order to reduce costs and environmental impact, people are constantly exploring new energy-saving technologies and resource recycling methods.
Shi Zhiyong's fighting spirit also inspires us to persevere and move forward courageously when facing difficulties and challenges.
In the future, with the continuous advancement of science and technology, domestic sewage treatment technology is expected to achieve greater breakthroughs. We look forward to the emergence of more efficient and environmentally friendly treatment equipment to make greater contributions to protecting our ecological environment.
Just as Shi Zhiyong always has a desire for victory, we should also yearn for a better environment and keep working hard.
In short, the development of domestic sewage treatment equipment and Shi Zhiyong's fighting spirit have made us understand that as long as we have firm beliefs and unremitting efforts, we can overcome difficulties and achieve our goals.
