METHOD FOR FABRICATING ORGANIC FERTILIZER OF BACTERICIDAL TREATMENT THE POLLUTED SEDIMENTS OF COASTAL FARMING AREAS

摘要

PURPOSE: A method for preparing an organic fertilizer is provided to recycle a seabed deposit to obtain a fertilizer of good quality in a short time so that the environment of costal sea area can be improved and efficiently conserved. CONSTITUTION: A method for preparing an organic fertilizer using sterilizing method of a polluting deposit in a costal nursery according to the present invention comprises the steps: a) pumping a seabed deposit and dewatering it; b) mixing organic wastes such as livestock feces and urine, human waste, triturated food wastes and sewage sludge with the dewatered seabed deposit; c) introducing a sterilizing additive to the mixed waste containing the deposit and organic wastes to obtain the safety from pathogenic micro-organisms which destruct coliform group, fecal coliform and viable cell and to improve the organic character of the mixed wastes wherein the sterilizing additive added in the said sterilization step c) is calcium oxide(CaO) and magnesium oxide(Mg(OH)2).
