In rural areas, many are not included in the sewerage network due to geographical, economic and technical constraints. This means that domestic wastewater treatment in these areas requires a different approach than in cities.
In township areas, natural treatment systems are a common way of treating wastewater. This approach utilises the natural purification capabilities of soil, plants and micro-organisms to treat domestic wastewater. Examples include wetlands, ponds and land treatment systems. These systems usually introduce domestic wastewater into a specific area and purify the wastewater by utilising the absorptive and filtering action of soil and plants, and the degrading action of micro-organisms. The advantages of this method are that it is low cost, simple to maintain and environmentally friendly. However, it has the disadvantage of relatively low treatment efficiency and requires a large land area.
In some larger townships, or more concentrated residential areas, centralised wastewater treatment plants may be constructed. This type of treatment plant usually concentrates domestic sewage from the neighbourhood and then carries out uniform physical, chemical and biological treatment. The treated effluent is usually disinfected, denitrified and dephosphorised, and discharged after meeting the discharge standards. The advantages of this type of treatment are that it has a large treatment capacity and high efficiency; the disadvantage is that it requires a large amount of capital and resources to be invested in its construction and operation.
Apart from the physical and engineering methods mentioned above, the government also plays an important role in the treatment of domestic sewage in townships. The government can guide residents and enterprises to pay more attention to sewage treatment and environmental protection by formulating relevant policies, such as sewage charges and environmental protection incentives. At the same time, through education and publicity, to raise the residents’ awareness of environmental protection, so that they can more actively participate in the process of domestic sewage treatment.
For some of the more developed townships, home-based sewage treatment equipment is also a common choice. This type of equipment is usually installed in the yard or near each family, and can be used to treat domestic sewage generated by the family in situ. The equipment has a number of internal components such as physical filtration, chemical reaction and biodegradation, which can remove organic matter, nitrogen, phosphorus and other substances from domestic wastewater. The advantage of this type of equipment is that it is flexible and convenient, and can be installed and used anywhere at any time.
In summary, the treatment of domestic sewage in township areas not included in the sewage network is a comprehensive problem that requires the combination of a variety of methods and technologies for treatment. In the selection of integrated wastewater treatment equipment for townships, Liding Environmental Protection can provide solutions and equipment according to different needs and actual situations.
