Nowadays, people’s awareness of environmental protection is getting higher and higher. Since the advocacy of “lucid water and lush mountains are golden mountains and silver mountains”, the classified treatment of domestic waste and the reasonable discharge of sewage are constantly being regulated. However, in many remote rural areas, the living facilities are relatively backward, without the support of corresponding rural sewage treatment equipment, and their sanitation environment is very poor, especially in terms of domestic water treatment, there is no good constraint, resulting in a vicious circle of worsening environment, worse economy, and worse life.
There are many types of rural sewage treatment equipment, and different equipment is suitable for different occasions.
1. Domestic sewage treatment equipment
Domestic sewage refers to the sewage discharged in people’s daily life, including sewage from households, schools, hospitals and other units. In rural areas, since there is no running water pipeline, most households use well water or river water. These water sources are generally not clean, so domestic sewage treatment equipment is very important.
At present, the more common domestic sewage treatment equipment includes: biological filter, artificial wetland, active pool, etc. These devices pass the sewage through different treatment methods to remove the pollutants and make it clean and harmless.
2. Livestock sewage treatment equipment
The rural livestock and poultry breeding industry is an important source of income for farmers, but the livestock and poultry manure and urine produced during the breeding process will pollute the environment and seriously affect the quality of life of the surrounding residents. Therefore, livestock and poultry sewage treatment equipment is also an important part of rural sewage treatment.
Common livestock and poultry sewage treatment equipment includes: biogas digesters, constructed wetlands, membrane separation, etc. These devices process livestock manure and urine through physical, chemical or biological methods to remove pollutants and make them harmless and usable.
In rural areas, the application of sewage treatment equipment is still relatively small, and a lot of sewage is directly discharged into rivers, which not only pollutes the environment, but also affects the health of local residents. So, which kind of sewage treatment equipment is more suitable for rural areas? Let’s discuss it together.
1. Biological filter
Biofilter is a relatively common sewage treatment equipment, which converts organic substances in sewage into inorganic substances through biodegradation, so as to achieve the effect of purifying water quality. Compared with other equipment, the cost of biofilter is lower, and the maintenance cost is also lower. At the same time, the treated water can be used for irrigation and other purposes.
2. Artificial wetland
Constructed wetland is a kind of sewage treatment equipment based on wetland ecosystem. It converts harmful substances in sewage into harmless substances through the action of plants and microorganisms, and can also effectively remove nutrients such as nitrogen and phosphorus. Compared with other equipment, the construction cost of artificial wetland is higher, but the operating cost is lower, and it does not require professional operation, so it is suitable for use in rural areas.
3. Anaerobic bioreactor
Anaerobic bioreactor is a sewage treatment equipment that can carry out biological reactions in an oxygen-free environment. It can effectively remove organic substances and nutrients such as nitrogen and phosphorus in sewage. Compared with other equipment, the cost of anaerobic bioreactor is higher, but it occupies a small area and does not require a large amount of power supply, so it is suitable for use in rural areas.
To sum up, different sewage treatment equipment has its own advantages and disadvantages, and the most important thing is to choose the equipment that suits you. When choosing sewage treatment equipment, it is necessary to consider comprehensively according to the specific situation, including economic strength, water quality requirements, environmental protection requirements and other factors. I hope that through this article, I can provide you with some references to make the sewage treatment work in rural areas smoother.
