The invention discloses an organic compound fertilizer with citrus pomace and a preparation method of the organic compound fertilizer and belongs to the technical field of preparation of organic fertilizers. The preparation method comprises the following steps of reducing the acidity of the citrus pomace by adopting microbial fermentation for deacidification, decomposing nondegradable components such as pectin and cellulose in the citrus pomace by adopting a compound-enzyme preparation, carrying out composting fermentation by microbial liquid inoculant, finally adding batched materials such as urea, monoammonium phosphate and potassium sulfate, and carrying out insect killing, sterilization, granulation, drying, cooling, sieving, coating and packaging to prepare the organic compound fertilizer with rich organic matter and the contents of N, P and K meeting the need of the optimal proportion for growth of citrus. The organic compound fertilizer and the preparation method disclosed by the invention have the advantages that deacidifying yeast is adopted to reduce the acidity of the citrus pomace and replace the existing method for adding quick lime to carry out deacidification, calcification and alkalization of soil are effectively prevented, the content of the compound fertilizer is more than 55%, the pH value is 6.5-8.5, the total contents of N, P and K are more than or equal to 8%, the water content is less than or equal to 20%, the contents of trace elements such as B, Zn and Mg are rich, and the other quality indexes are superior to national standard of organic fertilizer respectively.

The invention discloses a collocation method for fusing an intelligent plane warehouse and an overhead warehouse in aluminum plate strip production equipment. The intelligent plane warehouse is arranged between a hot rolling workshop and a cold rolling workshop; the overhead warehouse is arranged among an annealing furnace, each finishing unit and a tray conveying mechanism; a track for running of a plurality of coil cars is mutually vertical to the tray conveying mechanism; and a track for a plurality of discharge cars in the overhead warehouse extends beside the annealing furnace or the each finishing unit. Hot-rolled coils on a hot mill discharge mechanism are hoisted to the corresponding positions for storage or cooling through an intelligent crane in the intelligent plane warehouse, and cold-rolled coils are stored at the corresponding positions through a stacker or cooled in the overhead warehouse. The aluminum plate strip production equipment collocated with the intelligent plane warehouse and the overhead warehouse is totally adjoined, needs no transport equipment such as the crane, a forklift or an automatic vehicle and the like, has the effect on shortest transport distance, realizes good circulation of low-carbon production of aluminum plate strips, and has the characteristics of lowest product storage quantity and shortest production period.

The invention belongs to the field of paper-making pulping and particularly relates to an environment-friendly clean pulping process. The pulping process comprises four steps of: mechanical grinding, bleaching by using active hyperoxide, cyclic utilization of pulping residual water and comprehensive utilization of pulping tailing. According to the method, the mechanical grinding is used to replace chemical cooking for the pulping; environment-friendly chemicals are used for replacing conventional chemicals; the pulping process is changed; an air-source hot water pump is used to replace a boiler to provide hot-water circulation; and the purpose of environment-friendly clean pulping is achieved.
