With the vigorous advancement of the improvement of the rural human settlement environment, significant progress has been made in the treatment of rural domestic sewage, and some experience has been accumulated in the construction and management of facilities. However, in some places, there are still problems such as the lack of clear positioning of rural domestic sewage treatment work, unreasonable discharge requirements, and the need to explore technical models for treatment.
All localities should analyze and summarize the experiences of the comprehensive rural environment improvement projects and pilot projects of rural domestic sewage treatment, establish a rural domestic sewage treatment information database, and strengthen the applicability assessment of the adopted treatment technologies. Categorize and analyze population concentrated and scattered areas, mountains and plains, north and south, water-rich and water-scarce areas, and select rural sewage treatment models suitable for different local village conditions.
The economic conditions in rural areas are still relatively poor. The intensity of domestic sewage discharge is not high, and there is no need to invest too much energy. Some people think that the treatment of rural sewage should mainly treat areas with heavy pollution. In general, domestic sewage is not necessary. How to layout and promote lacks systematic consideration.
Plant liquid deodorant is not restricted by the climatic environment such as temperature, it will not be affected by the temperature and environment to prevent it from exerting its effect, and has strong weather resistance. They can give full play to their deodorizing effects; whether in wet or arid regions, their deodorizing effects are basically unaffected.
Plant deodorant is made by using equipment and technology with completely independent intellectual property rights to extract germicidal and deodorizing factors from plants. No chemical substances are added, without any toxic or side effects on human body and livestock, and it is safe to use. With antibacterial, bactericidal and deodorizing effects, it has a good decomposition and removal effect on malodors such as ammonia and hydrogen sulfide.
Guide local governments to choose small-scale domestic sewage collection methods and treatment technologies suitable for rural areas based on treatment effects, population size, climatic conditions, and funding capacity. In accordance with the main technical models, formulate more detailed technical specifications for rural domestic sewage treatment, and improve the professional level of rural domestic sewage treatment in various places.
Rural sewage treatment can be roughly divided into two levels to solve the problems of pretreatment of toilet waste and purification and treatment of sewage. The treatment of rural domestic sewage must first solve the sanitary problems of toilet waste, and further solve the problems of random sewage discharge and water environment treatment. For areas where the water environment is not sensitive enough, if the manure is treated well, timely cleaning and resource utilization can be used, the main problem of dirty sewage in domestic sewage can be solved. Therefore, the rural toilet improvement and sewage treatment need to be closely connected, and the overall planning and promotion of the rural human settlements should be promoted.
