Rural Sewage Treatment
With the rapid development of China's economy and society, sanitary facilities, washing machines, and bathing equipment have become common in rural households. The per capita daily water consumption and domestic sewage discharge in rural areas have increased sharply, generating a large amount of domestic sewage. However, the rural population is dispersed and large in number, with no collection and treatment facilities for domestic sewage. This makes rural domestic pollution a significant factor affecting the water environment, especially in water source areas and reservoirs, where it has a non-negligible impact on water quality. Moreover, it directly harms the health of farmers and can easily lead to the occurrence and spread of infectious diseases.
1. Water Quality Characteristics:
① Sewage distribution is scattered, covering a wide range with strong randomness, making prevention and control difficult. The pipe network collection system is underdeveloped, with extensive discharge and virtually no sewage treatment facilities.
② The concentration of rural domestic sewage is low and varies significantly.
③ Most rural domestic sewage has similar properties, with large water quality fluctuations and strong biodegradability.
④ The discharged sewage quality is poor but can be used as fertilizer after entering septic tanks.
2. Water Quantity Characteristics:
① The volume of domestic sewage in rural areas is generally small. Except for small towns, the rural population is dispersed, resulting in relatively low water consumption and small volumes of domestic sewage.
② The variation coefficient is large. Similar living patterns among residents lead to higher sewage discharge in the morning and evening compared to daytime, with minimal or even interrupted discharge at night, showing significant water quantity fluctuations.
Technical Advantages Existing engineering practices demonstrate that the Go Higher’s Flat Sheet Membrane MBR System offers the following advantages in rural sewage treatment:
1. The system can be designed as a small-scale water treatment plant or an integrated unit, increasing equipment flexibility and convenience. It is particularly suitable for treating dispersed, small, and variable rural sewage.
2. Compared to hollow fiber membrane bioreactors, the flat sheet membrane bioreactor can maintain stable operation with high flux (membrane water production) at higher activated sludge concentrations, with lower pre-treatment requirements.
3. The use of flat sheet membrane extends the lifespan of membrane elements. The installation of flat sheet membrane is convenient, simplifying the installation process and making equipment maintenance easier.
4. The flat sheet membrane has stronger fouling resistance, which helps increase sludge concentration within the equipment and improves treatment efficiency.
5. Combined with the environmental service system, it can operate unattended with regular inspections, reducing maintenance workload.
