Today in the 21st century, with the rapid development of industrialization and urbanization, environmental problems are becoming increasingly serious, among which water pollution has become one of the major bottlenecks restricting sustainable development. Facing this challenge, how to effectively treat sewage and reduce the risk in the treatment process has become a global issue. The purpose of this paper is to discuss how to effectively control the risk of sewage treatment by means of technological innovation and management optimization under the background of environmental crisis.

First, the current situation analysis

At present, many areas are facing serious water shortage and water quality deterioration. Industrial wastewater and domestic sewage are directly discharged into natural water without proper treatment, which not only destroys the ecological balance, but also poses a threat to human health. In addition, secondary pollutants such as sludge and harmful gases produced in the process of sewage treatment also bring new burdens to the environment. Therefore, it is particularly important to seek scientific and reasonable methods to improve sewage treatment efficiency and reduce potential hazards.

Second, technological progress and innovation

In recent years, with the development of science and technology, new and efficient sewage treatment technologies and equipment are constantly emerging. For example:

Biofilm method: Using specific microbial groups to attach to the carrier surface to form a biofilm, which can effectively remove organic matter, nitrogen and phosphorus and other nutrients in water.

Advanced oxidation process (AOPs): chemical reagents or physical methods are used to generate strong oxidants, which can rapidly degrade refractory organic substances, and it has the characteristics of good treatment effect and wide application range.

Membrane separation technology: including microfiltration, ultrafiltration, nanofiltration and reverse osmosis, etc., can accurately separate various impurities from wastewater and ensure the quality of effluent to meet high standards.

Third, the optimization of management mode

In addition to technical efforts, it is also essential to establish and improve relevant laws and regulations and strengthen industry supervision. The government should introduce more encouraging policies to support the R&D and application of green and low-carbon technologies; Enterprises need to enhance their sense of social responsibility and take the initiative to take measures to reduce environmental pollution; At the same time, the improvement of public participation will also help to promote the development of the whole society in a more environmentally friendly direction.

IV. Conclusion

To sum up, in the face of the increasingly urgent environmental crisis, we should actively embrace new technologies, constantly innovate sewage treatment methods, and reduce the risks in each link through effective management and system construction. Only in this way can we truly realize the recycling of water resources and leave a clean and beautiful home for future generations.
