Abstract: An electroactive bio-carrier module and a sewage treatment device using same are provided, which relate to the field of bioelectrochemistry and sewage treatment. The electroactive bio-carrier module is composed of an anode module and a cathode module made of a conductive material. The anode module is formed by connecting carbon fiber brushes in series and is of a vertically ring type structure; the cathode module is formed by connecting stainless steel meshes in series; the stainless steel meshes are in a folded horizontal stacked design; the anode and cathode modules are connected through an external lead wire to form a circuit. Surfaces of the anode and cathode modules can both enrich microorganisms, biofilms are formed on the surfaces. The electrode module is arranged in an up-flow type sewage treatment device and is used as an electroactive bio-carrier, to form a hybrid sewage treatment device with a built-in electroactive bio-carrier.

Abstract: The invention disclosed a password-sending-and-receiving device for logistics delivery and distribution by unmanned aerial vehicle (UAV), the technical scheme being the password-sending-and-receiving device. The device comes in two forms, the first form being the receiving end directly carries the authentication information for authentication, and the second form being that the receiving end obtains the authentication information through the network. In the first form, a password-sending-and-receiving device comprises three components: a Transmitter (10), an Authentication Service Information Server (20) and a Receiver (30) containing a Memory Module (31). In the second form, a Second Authentication Information Receiving Module (35) replaces the Memory Module (31). The Second Authentication Information Receiving Module (35) is connected to an Authentication Module (33), and is a wireless receiving module through wireless or wired network and can be used to receive authentication information sent by an Authentication Information Sending Module (22).
