With the acceleration of society and urbanization and the increasing expansion of industrial production, the problem of water pollution has become more and more serious, which has become one of the important factors restricting sustainable development. As an important part of environmental protection, the progress and application of sewage treatment technology plays an irreplaceable role in reducing environmental pollution and promoting resource recycling. This paper will discuss how to improve the efficiency by reducing all kinds of resistance in the process of sewage treatment, so as to reduce the environmental pressure.

First, optimize the design to reduce physical resistance

There are many physical obstacles in the process of sewage treatment, such as pipeline blockage and filter screen blockage, which will increase the treatment cost and affect the quality of effluent. Therefore, the principle of fluid dynamics should be fully considered in the design stage of the system, and reasonable layout and advanced material science should be adopted to ensure smooth and unimpeded water flow. For example, using large diameter pipeline can reduce friction loss; Using materials with strong corrosion resistance and high surface smoothness to make structures can effectively prevent the accumulation of dirt from causing secondary pollution.

Second, technological innovation to overcome the chemical reaction problems

In addition to physical problems, chemical reaction is also one of the reasons that make sewage treatment more difficult. Taking corresponding pretreatment measures for different types of pollutants or adjusting conditions such as pH value and temperature will help to speed up the degradation of harmful substances and shorten the whole process time. In addition, the introduction of new catalysts, microbial flora and other bioengineering techniques can also significantly improve the purification effect.

Third, management improvement to reduce human interference

Good operation and maintenance is the key to ensure the long-term stable operation of facilities. Regular cleaning of internal deposits of equipment, inspection of performance status of key components, and timely adjustment of operating parameters according to actual needs are all effective methods to prevent failures and prolong service life. At the same time, strengthening personnel training to improve their professional skills and service awareness can also avoid the risk of accidents caused by misoperation from the source.

To sum up, through comprehensive analysis and comprehensive policy on all aspects of sewage treatment, we can not only effectively reduce the resistance in this field, but also contribute to the ecological environment protection in a wider scope. future, relevant research will continue to deepen and policy support will continue to increase, and I believe that the prospects in this field will be broader.
