等因素。 Due to economic development constraints and weak environmental awareness, many domestic sewage in rural areas are discharged without treatment. In addition, rural areas are decentralized, have a wide area, many sources, and low treatment efficiency . Therefore, the treatment of rural domestic sewage is more troublesome. What are the commonly used rural domestic sewage treatment technologies? Warwick Environmental Protection Editor categorizes the following for you:
1.Aerobic biological treatment system
Aerobic biological treatment system is the most commonly used treatment technology in sewage treatment in new rural areas. 和比选,注重经济适用。 There are many aerobic biological treatment processes, each with its own advantages and disadvantages. When choosing, you must carefully demonstrate and compare the selection according to the actual situation , focusing on economical application.
2.Stable pond treatment technology
In China, especially in dry and arid regions, stable ponds are an effective method to implement the utilization of sewage resources. In recent years, it has become a technology that China has vigorously promoted. 物处理技术相比，高效藻类塘具有很多独特的性质，对于土地资源相对丰富，但技术水平相对落后的农村地区来说，是一种较具推广 价值的污水处理技术。 Compared with the traditional secondary biological treatment technology, the high-efficiency algae pond has many unique properties. It is a relatively popular sewage treatment technology for rural areas with relatively abundant land resources but relatively backward technology.
3. Artificial wetland treatment technology
后再进入二级人工湿地，二级人工湿地的出水回流至清水池，可供绿化、灌溉，也可溢流至附近坑塘。 After the rural domestic sewage is treated by the septic tank, the supernatant liquid enters the water well through the water collection pipe, flows into the sedimentation tank through the grille, and the precipitated supernatant liquid is pumped into the first-grade artificial wetland, and then enters the second- stage artificial wetland. Wetland, secondary artificial wetland effluent returns to the clear water pond, which can be used for greening, irrigation, or overflow to nearby pits.
4.MBR process technology
，悬浮物和浊度接近于零，生活污水处理后可直接回用。 Membrane bioreactor MBR is a high-tech developed at the end of the 20th century. It is a combination of membrane separation technology and activated sludge biotechnology. Its efficient solid-liquid separation makes the effluent water quality good , suspended matter and turbidity close to zero, and domestic sewage. Can be reused directly after processing.
村生态环境、提升人民生活水平有重大意义。 The above is Quan Ding's introduction to commonly used rural domestic sewage treatment technologies. For rural domestic sewage treatment, avoiding sewage and pollutants flowing directly into waters is of great significance to improving the rural ecological environment and improving people's living standards. Therefore, understanding how rural sewage should be treated is of great help to improve the environment.
