This invention relates to the field of wastewater treatment technology, and in particular to a microfiltration wastewater treatment device for industrial wastewater turbidity removal. The device includes a treatment cylinder and an L-shaped wastewater pipe installed at the top of the treatment cylinder. A swinging filter assembly is installed at the top inner part of the treatment cylinder. The swinging filter assembly shakes and filters the wastewater. The swinging filter cartridge within the swinging filter assembly swings and moves the filtered impurities. During the swinging process, the swinging filter assembly throws out the wastewater while simultaneously causing the filtered impurities to flow. This invention achieves dynamic separation through swinging filtration, combined with real-time self-cleaning via rotating scraping. The filter cartridge is automatically cleaned by a torsional brush assembly. A fixed filter cartridge with a blocking filter assembly effectively blocks filtration and also possesses a self-cleaning function. This allows for the simultaneous and continuous execution of filtration and cleaning processes, significantly improving wastewater turbidity removal efficiency and the stability and durability of the equipment operation.

The invention discloses a container real-time monitoring method based on the satellite internet, and relates to the technical field of container satellite positioning. An autonomous node is arranged in each container, and a dual-mode communication system is constructed through industrial internet satellite short message communication and UWB near-field grid communication. When satellite signals are normal, data are directly uploaded, and when the satellite signals are blocked, the data are converged to edge nodes for uplink through a multi-hop UWB link. Through a calculation mechanism combining relative positioning and absolute positioning, continuous position calculation in a satellite failure environment is realized. A controllable electromagnetic metamaterial unit is arranged on the surface of the autonomous node, and zero active radio frequency power consumption communication is achieved in a passive echo modulation mode. And in combination with a hierarchical grid structure and a dynamic edge node election mechanism as well as an energy collection and deep dormancy control strategy, low-power-consumption, continuous and anti-blocking real-time monitoring in a global environment is realized.
