MBR integrated sewage treatment equipment process
1. Pretreatment.
Pretreatment is the first step in the process of MBR integrated sewage treatment equipment, and the main purpose is to remove impurities such as large particulate matter, suspended solids, stones, and wood in sewage to protect the normal operation of the follow-up treatment equipment. Pretreatment generally includes equipment such as grilles and adjustment cells.
2. Filtration and separation of integrated sewage treatment equipment.
The pre-treated effluent enters the filtration and separation section of the integrated wastewater treatment plant. This part adopts advanced membrane filtration technology, through the filtration of microfiltration membrane or ultrafiltration membrane, the suspended solids and colloidal substances in the sewage are separated, and the bacteria, viruses and other microorganisms in the water are removed at the same time.
3. Biological treatment.
Biological treatment is a core part of the process flow of MBR's integrated wastewater treatment plant. In the biological treatment stage, the organic matter in the wastewater is broken down into carbon dioxide and water by microorganisms, while the microorganisms themselves are allowed to grow and reproduce. Through biological treatment, organic matter in sewage can be effectively removed and water quality can be improved.
Fourth, in-depth processing.
Advanced treatment is the further treatment of biologically treated wastewater. This stage generally includes activated carbon adsorption, disinfection and other steps. Activated carbon adsorption can remove trace organic substances and heavy metal ions in the water, and disinfection can kill the remaining microorganisms in the water to ensure that the effluent quality meets the discharge standard.
5. Disinfection. Disinfection is the last step in the process flow of MBR's integrated wastewater treatment plant. At this stage, disinfection methods such as chlorination and ozone method are generally used to kill the remaining microorganisms in the water and ensure that the effluent quality meets the discharge standard. At the same time, disinfection can also remove impurities such as odor and color in the water, and improve water quality.
In summary, the process flow of MBR integrated wastewater treatment equipment includes pretreatment, filtration and separation, biological treatment, advanced treatment and disinfection. These steps work together to complete the treatment and purification of the effluent, ensure that the effluent quality meets the discharge standards, and protect the environment and human health.
