  • Publication number: 20250059069
    Abstract: The present disclosure provides a vertical compact flotation unit with air stripping enhanced shallow sedimentation effect of spiral fins, and relates to the technical field of complicated treatment of oily waste water such as oil field polymer flooding produced water so as to give consideration to bubble utilization rate, operation energy consumption, structure compactness and installation and maintenance cost. The equipment includes a tank, an oil receiving structure, a swirling inner cylinder, a swirl breaking structure, sedimentation separation components and a center cylinder. An exhaust port is formed in the top of the tank, a slag discharge port is formed in the bottom of the tank, the side surface of the tank is provided with an oil spill port, a water outlet pipe and a water inlet pipe, and the water inlet pipe is tangentially connected with the swirling inner cylinder.

  • Patent number: 10616791
    Abstract: Disclosed are a data transmission method, apparatus and system for realizing, when a UE is in a non-connected state, that shunting transmission of a local service can be completed, and that the use efficiency of a wireless resource can be improved. The data transmission method comprises: after a data packet sent by a local service server is received by an MEC server, when it is determined that a UE for receiving the data packet is in an RRC non-connected state, sending the data packet corresponding to the UE to a P-GW so as to trigger a paging process of the UE; and the MEC server querying, in a pre-set duration, downlink bearer information for transmitting the data packet to the UE, and when the downlink bearer information is found, sending the data packet according to the downlink bearer information.

  • Patent number: 10462842
    Abstract: Disclosed are an S1AP signaling transmission method and apparatus. The method comprises: an intelligent mobile edge device receives an SCTP message carrying uplink S1AP signaling of a terminal sent by a Small Cell, determines an operator network corresponding to the terminal according to an S1AP ID carried in the uplink S1AP signaling, and sends the SCTP message carrying the uplink S1AP signaling to the He-GW of the operator network; the intelligent mobile edge device receives an SCTP message carrying downlink S1AP signaling of the terminal sent by the He-GW of the operator network, determines the Small Cell corresponding to the terminal according to an S1AP ID carried in the downlink S1AP signaling, and sends the SCTP message carrying the downlink S1AP signaling to the Small Cell. In this way, a Small Cell may access networks of multiple operators to provide network services for terminals of different operators.
