  • Patent number: 11939238
    Abstract: The present disclosure provides an apparatus and a method for hydrate-based wastewater treatment and cold storage. The apparatus for hydrate-based wastewater treatment and cold storage includes a water chilling unit, a hydrate-based cold storage tank, an airflow disturbance device, a water layer positioning system, a spraying system, a suction filtration system, a heat exchange system, and a system monitoring device. The water chilling unit provides a secondary refrigerant at a low temperature. The secondary refrigerant flows through an evaporator coil in the hydrate-based cold storage tank for heat exchange. The airflow disturbance device induces hydrate nucleation. The water layer positioning system positions a contact surface between a water layer and a hydrate former after hydrate decomposition to facilitate drawing and separation of the treated upper water layer. The spraying system and the suction filtration system enhance the solid-liquid separation efficiency to improve the removal rate of pollutants.

  • Patent number: 10084777
    Abstract: The invention discloses a secure data processing method and system, wherein the secure data processing method comprises the following steps of: a security control server receiving a data upload request from a terminal, and obtaining a file feature, an identification code of the terminal and a directory path of a file with the file feature in the terminal comprised in the data upload request; the security control server judging whether the terminal is a trustable machine and/or judging whether the directory path is a credit directory according to the identification code and/or the directory path, and if the terminal is a trustable machine and/or the directory path is a credit directory, adding the uploaded file feature into a security database, or otherwise, not adding it into the security database; the trustable machine is a terminal in which data is considered as secure data. The invention further provides a secure data processing system implementing the foregoing method.

  • Publication number: 20150281264
    Abstract: a security data processing method comprises the following steps that: a security control server receives a data upload request from a terminal, and obtains file features and an identification code of the terminal included in the data upload request; the security control server judges whether the terminal is a trustable machine according to the identification code of the terminal, wherein the trustable machine is a terminal in which data is considered to be security data; if the terminal is judged as the trustable machine, the security control server obtains a real-time state of the terminal from a real-time state record table, and adds the uploaded file feature to a security database if the terminal is in a working state, and does not add the uploaded file feature to the security database if the terminal is in an idle state. The present invention also provides a security data processing system for implementing the forgoing method.
