Abstract

The invention discloses an organic fertilizer produced by using sugarcane filter mud and municipal sludge. The organic fertilizer is prepared from the following raw materials, in parts by weight: 90-110 parts of the sugarcane filter mud, 80-100 parts of the municipal sludge, 30-40 parts of straw, 13-27 parts of rape seed cake, 20-30 parts of cassava residues, 19-26 parts of molasses, 7-17 parts of fish meal, 0.3-0.5 part of a decomposed microbial inoculum, 0.2-0.5 part of a heavy metal passivator A, 0.4-0.7 part of a heavy metal passivator B and 0.5-1.2 parts of an azotobacter fertilizer. The invention also provides a preparation method of the organic fertilizer produced by using the sugarcane filter mud and the municipal sludge. According to the formula and preparation method provided by the invention, the organic fertilizer obtained by fermentation by using the formula and the preparation method can continuously passivate heavy metals, accelerate the mineralization process of organic matter, improve composting efficiency, reduce nitrogen loss, and improve quality of sludge composting products; and the organic fertilizer has a good decomposing effect and high total nutrients, and is safe to crops.

Description

technical field [0001] The invention relates to the technical field of fertilizer preparation and utilization, in particular to an organic fertilizer produced from sugarcane filter mud and municipal sludge and a preparation method thereof. Background technique [0002] Sludge is the sediment produced in the process of wastewater treatment. It contains solid particles such as sediment, fiber, animal and plant residues and coagulated flocs mixed in domestic sewage or industrial wastewater. It is a variety of colloids, organic matter and adsorbed A comprehensive substance of metal elements, microorganisms, germs, insect eggs and other substances, the state is determined by the moisture content. With the continuous development of cities and the increase of population, urban sewage treatment plants have become an important means to solve water pollution. In the construction of urban sewage plants, a large amount of sludge is produced in the process of sewage treatment, and the s...
