Global environmental problems are becoming more and more serious, and water pollution and eutrophication have become major obstacles to the sustainable development of social economy. As one of the key means to solve these problems, the development and application of sewage treatment technology is particularly important. This paper will discuss some latest trends in sewage treatment in the field of environmental protection at present and in the future.

First, technological innovation leads the progress of the industry

In recent years, new sewage treatment technologies and equipment with high efficiency and low energy consumption are constantly emerging, and advanced technologies such as biofilm process and MBR (membrane bioreactor) are more and more widely used. These new technologies not only improve the treatment efficiency, but also effectively reduce the operation cost and the risk of secondary pollution. In addition, Internet of Things, big data, artificial intelligence and other modern information technologies are gradually integrated into the sewage treatment process, realizing intelligent management and optimal control, further enhancing the reliability and flexibility of the system.

Second, policy support to accelerate industrial upgrading

In order to meet the increasingly urgent demand for water resources protection, governments all over the world have introduced a series of policies and measures to encourage and support the development of sewage treatment industry. For example, China put forward the goal that the urban sewage treatment rate will reach over 95% during the Thirteenth Five-Year Plan period, and set up special funds to support related facilities construction and technical transformation projects; At the same time, enterprises that adopt energy-saving and emission-reduction processes are given tax relief or subsidy incentives, which promotes the rapid and healthy development of the whole industry.

Third, public participation promotes green transformation

In addition to the efforts of professional organizations, raising the awareness of water conservation among the whole people is also an indispensable part of improving water quality. Through various forms of publicity and education activities, enhance the understanding of the importance of water conservation in all walks of life; Encourage residents to use water-saving appliances to reduce household wastewater discharge; Advocate a low-carbon lifestyle and reduce the pressure on urban drainage system from the source. These measures are helpful to form a good atmosphere for the whole society to participate together and accelerate the construction of a beautiful home where man and nature coexist harmoniously.

Fourth, look to the future

Facing the uncertainties and challenges brought by climate change, the future sewage treatment needs to pay more attention to comprehensiveness and foresight. On the one hand, it is necessary to strengthen the research on the safe and stable operation of facilities under extreme weather conditions to ensure that they can play a role at critical moments; On the other hand, we should also explore how to use the treated reclaimed water for ecological water supply, agricultural irrigation and other fields to maximize its resource value. In short, only by constantly innovating ideas and methods can we better adapt to the development requirements of the new era and make greater contributions to building a beautiful earth.
