The application relates to a modular three-dimensional garage facilitating bicycle storage, and belongs to the technical field of traffic facilities. The garage frame is formed by splicing a plurality of standard modules through a unified interface. The transmission of bicycles is realized by the gear and rack mechanisms of mutual connection between the modules. The system has key module quantity identification and module topology identification functions, and the connected module quantity is detected in real time through PLC. During operation, the system cooperates with motors and sensors based on the automatically generated layout, and follows the logic of first moving horizontally to clear the channel and then lifting to adjust the parking position to complete accurate storage and taking. The core feature of the application is that the modular design thought of standardized units and expandability is adopted, the number of frame can be flexibly increased or reduced according to the size of the urban fragmented space, on-demand expansion is realized, and the site adaptability and reconstruction flexibility of the three-dimensional garage are improved.

The invention relates to the technical field of chemical sewage, discloses a pretreatment method of chemical sewage, and solves the problems of high treatment cost, low organic matter removal rate and poor resource utilization rate of existing production sewage of anthranilic acid, methyl anthranilate and saccharin sodium salt. According to the method, the sewage is subjected to salt component pretreatment, so that interference of inorganic salt on subsequent reaction is eliminated; then carrying out hydrolysis / alkaline hydrolysis treatment; then, through diazotization-coupling reaction, anthranilic acid components are directionally converted into 2-((5-hydroxy-3-methyl-1-phenyl-1H-pyrazol-4-yl) diazo) benzoic acid by-products with high additional value; and finally, cooling is carried out, and a phthalic acid crude product is separated out and recovered from the 2-((5-hydroxy-3-methyl-1-phenyl-1H-pyrazol-4-yl) diazo) benzoic acid by-products. The utilization rate of anthranilic acid components in the sewage reaches 99.9% or above, and meanwhile the method has the advantages of being low in treatment cost, small in equipment investment, short in technological process, high in resource benefit and thorough in sewage treatment.
