辽源市Buried Integrated Domestic Sewage Treatment Equipment: A New Solution to Rural Sewage Problems

          With the in-depth advancement of the rural revitalization strategy, the improvement of rural living environments has become a key priority, and domestic sewage treatment is a critical component. Traditional sewage treatment models suffer from high infrastructure costs, large land occupation and difficult operation and maintenance, which cannot meet the actual demands of rural areas. The emergence of buried integrated domestic sewage treatment equipment provides an efficient, economical and convenient new solution to rural sewage problems, and it is gradually becoming the mainstream choice for rural sewage treatment.

       Buried integrated domestic sewage treatment equipment adopts underground installation. The main body is buried underground, and the ground can be secondarily utilized for greening and hardening, which effectively saves land occupation. This feature makes it have prominent advantages in rural areas with tight homesteads and complex terrain. It does not require large-scale land leveling and can flexibly adapt to different geographical environments.

       The equipment integrates multiple units including pretreatment, biological treatment and advanced treatment into a whole, without the need to separately construct multiple structures such as grating tanks, grit chambers and biochemical tanks. This integrated design greatly simplifies the construction process of sewage treatment projects, shortens the construction cycle, reduces project construction costs, and meanwhile lessens the construction impact on the surrounding environment.

       This equipment adopts advanced biological treatment technologies such as A/O process and MBR process, which can efficiently remove pollutants including COD, BOD, ammonia nitrogen and total phosphorus in domestic sewage. Through reasonable process design and parameter regulation, the effluent quality of the equipment can steadily reach Grade A Level 1 standard or higher in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB18918-2002), meeting the requirements of rural sewage discharge or reuse.

       Buried integrated domestic sewage treatment equipment is equipped with advanced intelligent control systems to realize real-time monitoring, remote control and automatic adjustment of equipment operating status. Managers can check operating parameters and water quality data at any time through mobile APP or computer client, and troubleshoot equipment failures timely. Meanwhile, the equipment requires little maintenance work and does not need a professional operation and maintenance team, lowering the management cost of rural sewage treatment.

       Rural residents live scattered with small and fluctuating sewage discharge volume. We can flexibly select equipment models according to village population and sewage output to realize on-site treatment and reuse of sewage, solving the problems of difficult sewage collection and treatment in rural areas.

       The sewage treatment demand of small towns falls between cities and rural areas. Traditional centralized sewage treatment plants require high construction costs and large pipe network investment. Buried integrated domestic sewage treatment equipment can serve as a supplementary or alternative solution for small town sewage treatment, especially suitable for small towns with small population and weak economic foundation.

       Sewage discharge in tourist areas has obvious seasonality and volatility; sewage volume surges in peak seasons while remaining low in off-seasons. The buried integrated equipment can flexibly adjust operating load according to tourist reception capacity to guarantee effective sewage treatment and avoid resource waste caused by building large sewage treatment facilities.

       Some small industrial parks and enterprises produce a small amount of domestic sewage with stable water quality. This equipment can meet their sewage treatment needs to achieve standard discharge or recycling, cutting enterprises' environmental protection costs.

       With the continuous development of IoT, big data, artificial intelligence and other technologies, the intelligence level of the equipment will keep rising. Future units will be equipped with more advanced monitoring and control functions, supporting real-time detection of water quality indicators, automatic fault diagnosis and early warning, as well as intelligent optimization of operating parameters, further boosting operating efficiency and stability.

       To meet stricter effluent standards and lower energy and reagent consumption, process technology will keep innovating. New biofilm technology, advanced oxidation technology, membrane separation technology will be widely adopted to improve pollutant removal efficiency and reduce treatment costs.

       While disposing sewage, resource recycling is the future development trend. The equipment will pay more attention to reclaimed water reuse for farmland irrigation, landscaping and toilet flushing to improve water resource utilization efficiency. Meanwhile, sludge produced in the treatment process will be recycled into organic fertilizer for soil improvement to turn waste into treasure.

       With outstanding merits including small footprint, integrated structure, high treatment efficiency and intelligent operation, buried integrated domestic sewage treatment equipment provides an ideal solution for decentralized domestic sewage treatment in rural areas and other regions. As technology advances and application scenarios expand, this equipment will play an increasingly vital role in improving rural living environment and promoting ecological civilization construction. We firmly believe that buried integrated sewage treatment equipment will become mainstream equipment in domestic sewage treatment, making greater contributions to sustainable water resource utilization and environmental protection.
