Abstract:
     The present invention relates to a recovery technology of waste wet sludge in sugar mill. It is that a regulating agent is added in the wet sluddy having not yet been dry-processed, and through stirring mixing reaction, a mixed fertilizer with optimum physical performance and in the form of powder or grains can be made, and further nitrogen, potassium, rare-earth element and plant growth regulator are added in appropriate amounts, so that the binary or ternary composite fertilizer containing rare-earth element or plant growth regulator can be manufactured, therefore it changes the muddy smelly wet sludge into the powdered or grainy smelless fertilizer, and solves the environmental problem resulted from a large amount of wet sludge and has the great economic benefits and social benefits.
