Embodiments of the present invention provide a transfer module and a substrate processing apparatus including the same. The transfer module includes: a housing; a first transfer section for transferring a substrate and rotatably connected to the housing in a first rotational direction; a second transfer section for transferring a storage container containing the substrate, arranged vertically spaced from the first transfer section and rotatably connected to the housing in a direction different from the first rotational direction; a drive section connected to the first transfer section via a connecting member to provide power for rotating the first transfer section; and a transmission unit connecting the first transfer section and the second transfer section and transmitting the power to the second transfer section.

The invention discloses an efficient anaerobic sewage treatment device, and particularly relates to the technical field of sewage treatment.The efficient anaerobic sewage treatment device comprises a tank body, a tank cover is arranged at the top of the tank body, and a left partition plate and a right partition plate are arranged in the tank body; the inner space of the tank body is sequentially divided into a precipitation separation tank, an anaerobic tank and a biological filter tank from left to right by the left partition plate and the right partition plate, most of sludge and impurities with larger mass in sewage can be deposited at the bottom of the precipitation separation tank under the influence of gravity, and MBBR filler in the anaerobic tank is beneficial to quickly forming a biological membrane; the sewage is ensured to be in full contact with the filter material filler in the biological filter through the water guide pipe and the water distribution pipe, so that the effects of filtering and degrading the pollutants are realized, and as the liquid level difference exists between the water inlet pipe and the water outlet pipe, the whole device can realize unpowered treatment of the sewage without additionally arranging an additional power assembly; the purpose of saving energy is achieved, and meanwhile operation cost is reduced.

This application relates to a control method, apparatus, equipment, and storage medium for a plasma arc melting furnace. The melting furnace is used to treat secondary hazardous waste. The furnace includes a constant current source, a first electrode, and a second electrode. The constant current source is connected to both the first and second electrodes, and its output current is introduced into the furnace through the electrodes. The method includes: adjusting the height of the first and second electrodes until they contact the secondary hazardous waste inside the furnace; wherein the surface of the secondary hazardous waste is covered with an arc-initiating agent; after successful arc ignition, adjusting the output current of the constant current source based on the arc voltage and furnace temperature; if the furnace temperature meets a second preset condition, adjusting the output current based on a preset increment; and after the arc power reaches a target power, adjusting the height of the first and second electrodes based on the difference between the arc power and the target power. This solves the problems of difficult arc ignition and inconsistent output power when the melting furnace treats secondary hazardous waste.

The invention discloses a card number traceability anti-counterfeiting generation method and system for an exchange card. The method comprises the following steps: generating 16-bit plaintext data; wherein the 16-bit plaintext data comprises three plaintext sub-parts; performing encryption hash processing and byte interception processing on the 16-bit plaintext data to obtain a 7-bit decimal short code; accessing the 7-bit decimal short code into 16-bit plaintext data to obtain 23-bit data; generating a 1-bit check code according to the 23-bit data; accessing the 1-bit check code into 23-bit data to obtain a 24-bit card number; and offline verification is carried out on the 24-bit card number, so that whether the 24-bit card number is qualified or not is judged. In a 24-bit pure digital space, a 16-bit plaintext + 7-bit ECDSA signature + 1-bit Luhn verification code is used for forming a signature code capable of being verified offline, a signature value is taken from a cryptographic random number of a standard elliptic curve private key, a Merkle tree is constructed at a time, root hash is written into a non-tampering medium, logistics, sales, exchange and other events are added step by step to form a chained log, and the chained log can be verified offline. And double anchoring of closed batches and additional events is realized.
