With the rapid development of our country’s economy, the amount of urban garbage has also increased. A large amount of garbage has had a great impact on people or the environment. The proper disposal of garbage has It has become an urgent problem for people to solve. Most garbage is landfilled or incinerated. However, due to the presence of rain or surface water, the microorganisms present in the garbage will undergo some chemical reactions, resulting in a high concentration and complex composition. The organic waste liquid is what people call landfill leachate. ptfe microporous membrane manufacturer has proposed a solution to this problem.
Landfill leachate is a highly polluting, high-concentration organic wastewater that affects the surrounding environment, landfill subsoil and Groundwater has caused great pollution, seriously affecting the urban living environment, and has become a difficulty in garbage disposal. To solve this difficulty, we must prescribe the right medicine, first analyze the causes and characteristics of the difficulty, and then select appropriate treatment methods to solve it. Today we will introduce ptfe microporous membrane manufacturer’s landfill leachate treatment method: biological treatment + membrane treatment process. Process content: The leachate flows into the medium-temperature anaerobic tank through the regulating tank. After being degraded by macromolecular organic pollutants, it enters the anoxic section MBR reactor. It is mixed with the return water and enters the aerobic section MBR for aeration to remove pollutants in the leachate. TN, the effluent from the aerobic pool enters the MBR separator, and the separated sludge concentrate is returned to the anoxic section of the MBR. The MBR effluent enters the reverse osmosis system, and the leachate is discharged up to standard after reverse osmosis treatment.
After market application, it was found that the immersed MBR has more advantages than the external tube membrane. At present, through the implementation of different leachate projects, it is concluded that the immersed MBR System, only ultrafiltration membranes made of polytetrafluoroethylene (PTFE) can handle landfill leachate well.
ptfe microporous membrane manufacturerThe microporous filtration membrane prepared from ptfe as raw material is the core material of MBR and has a high rejection rate , low pressure difference and wide chemical compatibility. Interested parties can enter the store for consultation and purchase!
