As the world pays more attention to clean water resources and sustainable development, the problem of domestic sewage treatment in rural and remote areas is becoming increasingly prominent. The LD scavenger® household sewage treatment equipment independently developed by Liding Environmental Protection has been successfully applied to many overseas family projects with its high efficiency, energy saving, convenient installation and water quality that meets standards, becoming an ideal choice for solving rural domestic sewage problems.
Project background: centralized treatment of domestic sewage
In this project, the client is a rural single-family user overseas. The project mainly treats black water and gray water from the kitchen, bath and toilet. Considering the actual conditions such as the lack of municipal sewage pipe network coverage, limited power supply resources and strict emission standards, Liding Environmental Protection customized a LD scavenger® household machine for it, realizing the on-site treatment and resource utilization of domestic sewage.
Project Scope: Treatment of household domestic sewage
Equipment: LD scavenger® household sewage treatment plant (STP)
Daily Capacity: 0.5 m³/d
Sewage Treatment Technique: MHAT + contact oxidation
Technology Highlight: MHAT + contact oxidation, High-Quality Effluent
LD scavenger® system integrates an MHAT + contact oxidation process, combining anaerobic and aerobic treatment stages, biological contact oxidation, and sedimentation. This advanced approach effectively removes COD, ammonia nitrogen, and total phosphorus. The effluent quality is stable and up to standard, and is also suitable for agricultural reuse through an irrigation mode — allowing for resource recovery of nitrogen and phosphorus.
Clean energy drive: solar power supply, green and low-carbon
Taking into account the shortage of power resources in the project area, the equipment integrates a solar panel power supply system, which can achieve stable operation with the combination of city power + solar power supply, further reducing carbon emissions and operating costs. The whole machine has low power and low energy consumption, providing a strong guarantee for achieving the goal of "low-carbon and environmental protection" at the household level.
Application effect: This project realizes the centralized treatment of household black and gray water after collection by installing LD scavenger® household sewage treatment plant. The effluent treated by the household machine can not only meet the direct discharge standards, but also be combined with the "irrigation" mode of the household machine to use the treated effluent to irrigate crops and realize the recycling of nitrogen and phosphorus resources. The household machine is equipped with solar panels, with low energy consumption, energy saving and environmental protection.
Sustainable Impact & Market Value
LD scavenger® household sewage treatment plant is designed for rural households, small farms, remote settlements and other non-pipeline scenarios. The successful implementation of this case not only improves the quality of the user's living environment, but also provides global household users with an integrated, energy-saving and sustainable domestic sewage treatment solution.
