Linqu Mobile Toilet Treatment

The solutions for treating mobile toilets in Linqu mainly include three modes: integrated sewage treatment equipment, sewage treatment equipment specifically for scenic spots, and leasing services. Details are as follows:

1. Integrated Mobile Toilet Sewage Treatment Equipment
Developed by Weifang Longyu Environmental Protection Technology Co., Ltd., this equipment adopts modular biological treatment technology, with a biological membrane purification system at its core. The equipment can be buried underground, and the surface space can be reused for greening or activity areas, achieving efficient space utilization. Its treatment process consists of three stages: Grade A biochemical tank (anaerobic treatment), Grade O biochemical tank (aerobic treatment), and sedimentation tank. It decomposes organic matter and removes pollutants such as nitrogen and phosphorus through microorganisms. The equipment features fully automatic operation, strong pollution resistance, and low power consumption. After treatment, the water quality can meet the 'Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants' (GB18918-2002), making it suitable for the sewage treatment of mobile toilets in long-term fixed locations.

2. Sewage Treatment Equipment for Mobile Toilets in Scenic Spots
For temporary or non-piped network scenarios (such as scenic spots and exhibitions), Weifang Longyu Environmental Protection offers compact, mobile, and integrated solutions. The mainstream equipment types include:

• Integrated biochemical treatment equipment: It adopts the AO/MBR biological membrane + sedimentation + disinfection process. Through the alternating reaction of anoxic and aerobic conditions, it improves the denitrification efficiency. The MBR membrane filtration achieves mud-water separation, with advantages such as small footprint (≤5㎡), low sludge volume (≤0.2kg/m³ of sewage), and strong resistance to shock loads. The treated water can be reused for toilet flushing or discharged up to standard.
• Microbial water circulation treatment system: It utilizes special microorganisms to degrade pollutants and combines with circulation filtration technology to achieve zero sewage discharge, suitable for water-scarce areas.
• Foam/packaging-type equipment: It reduces odors by covering feces and urine with foaming agents or directly collects them using degradable bags without water flushing, suitable for extreme environments.
• Container/skid-mounted equipment: Its modular design facilitates rapid deployment and supports the parallel connection of multiple units for large-scale sewage treatment.

3. Mobile Toilet Leasing Services
Linqu Liwei 365 provides a nationwide leasing network covering 20 urban warehousing centers with 3,000 units of equipment. It has served over 5,000 events, including the Olympic Games and National Games. The leasing service includes the entire chain of equipment transportation, installation, maintenance, and fecal sludge removal. It supports billing by day or by use, can flexibly respond to short-term event needs, and reduces users' initial investment costs.

Selection Recommendations:

• For long-term fixed locations, prioritize integrated sewage treatment equipment to balance environmental protection and space utilization.
• For temporary scenarios such as scenic spots and exhibitions, recommend equipment specifically for scenic spots and select specific types according to water volume and discharge requirements.
• For short-term events, it is advisable to adopt leasing services for quick response and cost control.
