Treatment methods of toilet sewage in scenic spots

There are two main methods to treat toilet sewage in scenic spots: centralized sewage treatment and decentralized sewage treatment. Centralized sewage treatment is to collect sewage from toilets and other sewage sources (such as restaurants and accommodation areas) to sewage treatment plants for treatment. This method is suitable for large-scale scenic spots with high tourist density, which can discharge sewage centrally and is convenient for maintenance, management and monitoring. Sewage treatment methods include primary treatment, biological treatment and advanced treatment, such as activated sludge method, constructed wetland and reverse osmosis technology.

Decentralized sewage treatment is to connect the sewage from toilets and other sewage sources to their respective treatment facilities for treatment through underground drainage pipes, such as biochemical tanks or activated carbon treatment equipment. This method is suitable for scenic spots with complex terrain conditions, which can treat sewage more flexibly and reduce the cost and energy consumption of sewage collection and transportation. In addition, green environmental protection measures such as plant purification, ecological restoration and resource utilization can also be carried out through constructed wetlands and plant filtration.

No matter what sewage treatment method is adopted, there must be an effective sewage collection and treatment system before it, and natural and environmental protection methods should be adopted as far as possible in sewage treatment to minimize environmental pollution. The sewage treatment and management in scenic spots should be scientifically planned and designed according to the specific conditions, and supervision should be strengthened to ensure that the sewage discharge in scenic spots meets the environmental protection standards, protect the ecological environment and provide a clean and hygienic tourism environment for tourists.
