The facultative H3MBR integrated sewage processor (facultative H3MBR technology) completes denitrification and phosphorus removal through intermittent aeration and intermittent water inflow, removes organic matter, and separates mud and water through membrane modules. Jian oxygen membrane bioreactor (Jan oxygen H3MBR technology) is based on the conventional Mitsubishi MBR technology of Shenzhen Evergrande Xingye Environmental Protection Technology Co., Ltd. and Mitsubishi Chemical Company (mesh-hole composite structure, continuous filament, no backwashing, no external cleaning) Based on the new H3MBR process independently researched and developed, the process integrates membrane modules and biological reaction tanks into integrated equipment, including the main reaction zone, equipment zone, clean water zone and corresponding pipeline facilities. The schematic diagram of the facultative H3MBR is shown in Figure 1.1. The main reaction zone includes membrane modules, biological tanks and aeration system. The equipment area is equipped with supporting electrical equipment and system control modules (using PLC control modules and "Hengda Cloud Platform" to achieve Unattended and remote dynamic monitoring). The reactor has completely improved the conventional MBR technology by optimizing and controlling the process parameters. Compared with the conventional MBR, it has the advantages of high efficiency and low consumption, and has successfully established facultative oxygenation, successfully achieved near-zero discharge of organic sludge, and successfully achieved wastewater gasification and removal.
