NOVELTY - A liquid fertilizer manufacturing method involves collecting organic waste for preparing brine. Organic acid is added with the brine for removing sodium chloride. A complex salt is prepared by adding sea water followed in segregation process. The salt is pre-processed in an organic waste water reservoir (1). The salt is transferred into an aerobic fermentation tank (11), and is processed by using organic waste water for producing liquid fertilizer. A corrosion precursor is added in the fertilizer. Metabolic product of polyphenol compound is separated from the fertilizer.    USE - Method for manufacturing liquid fertilizer from organic waste such as livestock excretions in a slaughter factory, human excrement, food waste in a food processing factory, and marine product waste in an aquatic product processing factory (all claimed).    ADVANTAGE - The method enables avoiding utilization of water control agent for manufacturing the liquid fertilizer, so that manufacturing cost of the liquid fertilizer is reduced effectively.    DETAILED DESCRIPTION - A liquid fertilizer manufacturing method involves collecting organic waste e.g. livestock waste, human waste, food waste and marine products, from a food processing factory or a slaughter factory for preparing brine. Organic acid is added with the prepared brine for removing sodium chloride. A complex salt is prepared after removing the sodium chloride in the brine by adding liquid component i.e. seawater. The complex salt is segregated. Iron salt is added with the segregated salt. Bad odor foreign substance is removed in the segregated salt through an influx container. The segregated salt is pre-processed in an organic waste water reservoir (1) by supplying organic waste water. A demineralizer is arranged at an inner side of a depletion chamber. Air is injected by an organic waste water feed pump (2) from a blower (18) for sending microbial cell of the salt to a settling tank (12). A solid material is formed in the settling tank through a precipitation process. The solid material is transferred into a bioactivator reactor (15). A mineral i.e. porosity silica mineral, is radiated in a filling part (17) of the bioactivator reactor. Ceramics e.g. negative ion ceramic and magnetism ceramic, is radiated on the mineral. The segregated salt is transferred into an aerobic fermentation tank (11). The transferred segregated salt is processed by using organic waste water according to microorganism for producing liquid fertilizer. Corrosion precursor is added in the produced liquid fertilizer. Metabolic product of polyphenol compound is excreted from the liquid fertilizer.
