Domestic sewage treatment equipment, as an important part of modern urban environmental governance, its role is becoming increasingly prominent. This article will lead readers to have an in-depth understanding of the relevant knowledge of domestic sewage treatment equipment, including its working principle, classification, application fields and future development trends.
First, the working principle of domestic sewage treatment equipment.
Domestic sewage treatment equipment mainly adopts the comprehensive application of physical, chemical and biological methods. Remove large particles and suspended solids in sewage through physical treatment equipment such as grids and grit tanks; Then, through biochemical treatment equipment such as conditioning tanks and aeration tanks, the organic matter in the sewage is decomposed into harmless substances such as carbon dioxide and water by using the metabolism of microorganisms. Finally, through sedimentation, filtration, disinfection and other steps, the treated water quality meets the relevant national discharge standards.
2. Classification of domestic sewage treatment equipment.
According to the different treatment processes, domestic sewage treatment equipment can be divided into activated sludge method, biofilm method, natural treatment method and other types. The activated sludge method is currently the most widely used one, which forms activated sludge in sewage by cultivating a large number of microorganisms, and removes organic matter in sewage through sludge adsorption, oxidation and other effects. The biofilm method is to use the microorganisms on the biofilm to purify the sewage, and the common biofilm methods include biological filters, biological turntables, etc. The law of natural treatment is to use the purification capacity of nature to treat sewage, such as stabilization ponds, land treatment, etc.
3. Application fields of domestic sewage treatment equipment.
Domestic sewage treatment equipment is widely used in urban domestic sewage treatment, rural domestic sewage treatment, scenic domestic sewage treatment and other fields. In urban life, with the continuous increase of population and the acceleration of urbanization, the amount of domestic sewage is also increasing, and the construction and operation of domestic sewage treatment equipment is of great significance to improve the urban water environment and ensure people's health. In rural areas and scenic spots, the construction and application of domestic sewage treatment equipment also help to improve the local environmental quality and quality of life.
Integrated sewage treatment equipment Fourth, the future development trend of domestic sewage treatment equipment With the progress of science and technology and the improvement of environmental protection requirements, the future development trend of domestic sewage treatment equipment will pay more attention to high efficiency, energy saving, environmental protection and intelligence. On the one hand, new treatment processes and technologies will continue to emerge to improve the efficiency and effectiveness of sewage treatment. On the other hand, domestic sewage treatment equipment will pay more attention to energy saving, emission reduction and resource utilization, reduce treatment costs, and achieve sustainable development. At the same time, with the application of technologies such as the Internet of Things and big data, the intelligent level of domestic sewage treatment equipment will also be improved, and the functions of remote monitoring and intelligent control will be realized, so as to improve the stability and reliability of equipment operation. To sum up, domestic sewage treatment equipment plays an important role in modern urban environmental governance. By gaining an in-depth understanding of its working principle, classification, application fields and future development trends, we can better understand and apply this technology to make greater contributions to improving the water environment and protecting people's health.
