The present invention discloses a xylose hydrolysate decolorization and filtration device. A hydrolysate is filtered through a to-be-cleaned filtering machine to form a waste carbon liquid with a light transmittance of 7% to 10%, the waste carbon liquid is subjected to pressure filtration through a filter press to form a plate and frame liquid, the plate and frame liquid is filtered through a to-be-passed-through filtering machine to form a pre-decolorized liquid with a light transmittance of 30% to 35%, the pre-decolorized liquid enters a decolorization tank and is mixed with added new carbon in the decolorization tank to form a new carbon liquid, and the new carbon liquid is filtered through a standby filtering machine to form a decolorized liquid with a light transmittance of greater than 65%. The present invention further discloses a xylose hydrolysate decolorization and filtration method using the device. According to the present invention, the pollution of carbon powder to the surrounding environment is effectively reduced, the xylose hydrolysate is effectively decolorized and filtered, the device is designed in a compact way and takes up less space, and the entire decolorization and filtration process is carried out in a sealed environment, which reduces the pollution to the surrounding environment.

Embodiments of the present application provide a data transmission method, a camera and an electronic device. The method includes: acquiring to-be-sent target data; and sending the target data, as data carried in an effective image area of a first image frame, by using a data sending manner for the effective image area, through a same transmission channel as used in transmitting image data; wherein, the target data is different from the image data and coaxial data, the coaxial data is notification information for an interaction between a data receiving end and a data sending end, and the first image frame has a different type from a second image frame carrying the image data without carrying the target data. Applying the solutions provided by the embodiments of the present application, the transmission of the target data can be realized without additional wiring, thereby reducing the device cost.

Data transmission method, camera and electronic device

Method for transmitting data, camera, and electronic device. The method includes: obtaining an to-be-sent image and to-be-sent target data; determining a first position for the to-be-sent image in an effective image area of an image frame, and determining a second position for the target data in an effective image area of an image frame; taking the to-be-sent image and the target data as data of the same image frame, and sending the to-be-sent image according to the first position and the target data according to the second position in a data sending mode for the effective image area. Target data is data other than to-be-sent image and coaxial data, and coaxial data is notification information exchanged between a data receiving end and a data sending end. Target data and to-be-sent image can be sent to an electronic device through the same image frame without additional wiring. Facility costs are reduced.

The disclosure discloses a high-performance liquefaction mitigation method forstone columns for protecting the existing buildings during earthquakes. Specifically, a small equipment is used to dig trenches in the soil around the existing building. Then, a spiral driller is used to drill a series of boreholes in the trenches according to the optimized borehole design. Next, two or three layers of optimized gravel material with high permeability are filled into the boreholes to work as the inverted layer. Finally, geotextile is arranged around the trench and the trench is filled with the optimized gravel. Compared with current liquefaction mitigation methods for existing buildings, the disclosure is suitable for liquefaction mitigation in large cities, and has the advantages of low disturbance to the overlaid building, simple construction process, high construction efficiency, low construction cost, long service life and the construction material could be easily obtained.
