MBR membrane application river management method
The application of MBR membrane technology in river management is mainly to remove suspended solids, bacteria and viruses in sewage through its efficient solid-liquid separation capability, while degrading a certain amount of organic matter, thereby improving river water quality. Specifically, the application of MBR membrane technology in river management can include the following aspects:
1. Urban sewage treatment: Urban domestic sewage and industrial wastewater are one of the main sources of river pollution. MBR membrane technology can be used as the core treatment process of sewage treatment plants. This sewage can be discharged into rivers after deep treatment, which can significantly improve the quality of discharged water and reduce pollution to rivers.
2. Rainwater runoff treatment: Urban rainwater runoff often contains large amounts of suspended solids, heavy metals, organic pollutants, etc. Direct discharge into rivers will cause pollution. Using MBR membrane technology to treat these rainwater runoffs can effectively remove pollutants and protect the river water environment.
3. Ecological restoration: Combined with ecological restoration technologies such as artificial wetlands and floating islands, MBR membrane technology can further improve the water quality treatment effect and restore the ecological balance and self-purification ability of the river.
4. River water purification: In river management projects, mobile or fixed MBR membrane treatment facilities can be set up to purify the water in the river on-site, remove suspended solids, organic matter, nutrients and other pollutants in the water, and improve the water quality. .
5. Advanced treatment and reuse of tail water: MBR membrane technology can be used as an advanced treatment step of tail water in traditional sewage treatment processes to further remove residual pollutants in the tail water, so that the treated water reaches a higher standard and can be used in landscapes Water recharge, agricultural irrigation, industrial recycling water, etc. reduce the demand for river water resources.
The application of MBR membrane technology in river management can not only improve river water quality, but also reduce environmental pollution and improve the ecological environment. However, the initial investment and operating costs of MBR membrane technology are relatively high. Therefore, in practical applications, factors such as economy, technical feasibility, and later maintenance management need to be comprehensively considered. In addition, the service life, pollution and clogging problems of MBR membranes also need to be solved through scientific operation management and regular cleaning and replacement.
