Scenic area sewage treatment is a multi-step, multi technology comprehensive treatment process aimed at protecting the environment and enhancing the tourist experience. Through reasonable collection, treatment, and utilization of sewage, it is possible to achieve standard discharge of sewage, protect water resources and ecological environment.

What are the hazards of poor sewage treatment in scenic areas

Scenic areas, tourist towns, and resorts are generally located in remote suburbs, surrounded by mountains and rivers, with beautiful environments and pleasant scenery. The construction of sewage pipelines in scenic areas lags behind, and the lack of sewage treatment facilities in scenic areas has always been a common problem. With the explosive increase in the number of tourists, the problem of domestic sewage treatment has gradually become prominent. If the domestic wastewater from toilets, restaurants, hotels, villas, and homestays in the scenic area is discharged directly for a long time without a reasonable treatment plan, it may affect the drinking water source, cause black and odorous water, and cause serious environmental pollution. Some scenic spots have also been reported and exposed for inadequate sewage treatment measures, and have been punished, even demoted or delisted from the 5A scenic spot title.

Several major challenges faced by current wastewater treatment in scenic areas

1. The composition of wastewater in scenic areas is complex, with a high proportion of oily catering wastewater and black water in toilet wastewater. The concentration of domestic wastewater is low. Should it be treated separately or in combination?

2. The amount of water is difficult to estimate, and the amount of wastewater generated by scenic spots varies greatly between the off-season and peak season, making it difficult to determine the required scale of sewage treatment stations.

3. Environmental protection standards are becoming increasingly strict in various regions, and many scenic spots are close to water sources. How to choose efficient and stable equipment based on discharge standards to achieve standard discharge of domestic sewage or zero discharge of wastewater.

4. Many scenic area sewage treatment facilities use high energy consumption integrated sewage treatment equipment, which has high operating costs.

Process flow of wastewater treatment in scenic areas

1. Ordinary domestic wastewater: domestic sewage → septic tank → collection tank → regulating tank → sewage treatment equipment → standard discharge → reclaimed water tank → reuse equipment → reclaimed water reuse

2. Oily catering wastewater: oily wastewater → oil separation tank → septic tank → regulating tank → sewage treatment equipment → standard discharge
