Abstract

The invention relates to an organic composite fertilizer produced by using paper making sludge and a manufacturing method thereof, which are characterized in that: paper making sludge powder, cow dropping powder, sheep manure powder, chicken manure powder, quick lime powder, calcium hydrophosphate, ammonium nitrate, potassium sulfate, sodium borate, ferrous sulfate, magnesium sulfate and Li macromolecular heavy metal collector are used as raw materials; the raw materials are mixed uniformly in a mixing stirrer to form the paper making sludge organic composite fertilizer product; the product has the advantages of containing various nutrients, such as nitrogen, phosphorus, potassium, various micro elements and organic acids, which can meet the needs for growth of crops, preventing secondary pollution, protecting environment, saving land, along with no pollution, low cost and great benefits.

Description

technical field [0001] The invention relates to an organic compound fertilizer produced by papermaking sludge, specifically, it is an organic compound fertilizer produced by using sludge discharged from papermaking, cow manure, sheep pen manure and chicken manure as main raw materials, and belongs to the field of waste treatment . [0002] The invention also relates to a manufacturing method of the organic compound fertilizer. Background technique [0003] Papermaking sludge is the industrial wastewater produced in the process of producing various papers in the paper mill and the domestic sewage discharged from the living area of ​​the factory. A kind of mixed solid waste obtained from froth, the composition sources of papermaking sludge are relatively complex, which contains a large amount of cadmium, mercury, lead, chromium, arsenic, nickel, zinc, copper, cyanide, pathogenic bacteria, parasite eggs , organic pollutants and other heavy metal elements and toxic and harmful s...
