Customer Profile: As a national 5A level tourist attraction, a scenic spot in Jiangxi attracts a large number of tourists with its unique natural scenery. The scenic area has complete supporting facilities, including public toilets, waiting halls, supermarkets, restaurants, hotels, etc. Due to the large long-term flow of people, a huge amount of domestic and catering wastewater is generated. The person in charge of the scenic area contacted Baihuipu Environmental Protection, who has rich experience in the field of wastewater treatment in the scenic area, hoping to properly solve the problem of domestic wastewater treatment in the region. The plan is to collect and treat the sewage from the waiting hall, residential resettlement area, and several public toilets in a centralized manner, and discharge the treated sewage into the surrounding rivers.

Water quality characteristics
After our technical team conducted testing and analysis on the sampled sewage, it was found that the wastewater generated by the scenic area is highly similar to urban domestic sewage, but COD (Chemical Oxygen Demand) and BOD (Biochemical Oxygen Demand) are slightly higher than urban domestic sewage. This means that the organic content in the water is relatively high, which slightly increases the difficulty of treatment.
Water fluctuation In terms of water volume, the sewage discharge in the living area of the scenic spot is significantly affected by the peak and off peak seasons of tourism. During the peak tourism period from June to October, the daily sewage volume is about 500 tons; During the off-season of tourism, the sewage volume is less than 50 tons per day, and the large fluctuations in water volume pose challenges to the operation of sewage treatment equipment.
Collection stage: Sewage from public toilets, domestic wastewater from waiting halls, and domestic wastewater from residential resettlement areas are collected through a unified pipeline network and flow into septic tanks. The septic tank plays a role in initial sedimentation and anaerobic fermentation, removing some suspended solids and organic matter, and reducing the load on subsequent treatment units. Upgrading stage: The clear liquid from the upper layer of the septic tank flows into the lifting well, and then the sewage is pumped into the sewage treatment equipment in the residential resettlement area. The lifting effect of the water pump ensures that the sewage can smoothly enter the subsequent treatment process and maintain the water flow power of the treatment system. Biochemical reaction stage: Biochemical reactions are carried out inside the sewage treatment equipment, using appropriate biological treatment technology to utilize the metabolic process of microorganisms to decompose and convert organic matter in the wastewater into harmless substances such as carbon dioxide and water, further reducing indicators such as COD and BOD. This is the core link of the entire treatment process, playing a crucial role in water purification. 4. Disinfection stage: After biochemical reaction, the sewage is finally disinfected to kill pathogenic microorganisms such as bacteria and viruses in the water, ensuring that the effluent meets the national standard Class A discharge standard. The disinfection method adopts safe and efficient methods to ensure the disinfection effect while avoiding secondary pollution. 5. Discharge: The treated effluent meets the standard and is directly discharged into the surrounding rivers. As the water quality has already met the standard, it will not cause pollution to the surrounding water environment.
