Embodiment 1

[0010] Example 1 Take 6 parts of filter mud, 2 parts of heavy superphosphate, and 1 part of calcium-magnesium phosphate fertilizer and mix them evenly. After standing for one day, it becomes a mixed fertilizer containing 15% of available phosphorus.

Embodiment 2

[0011] Embodiment 2 Get 5 parts of filter mud, 4 parts of ammonia superphosphate, and 1 part of combustion ash and mix evenly to become a mixed fertilizer containing 8% of available phosphorus and 2-3% of ammonia.

Embodiment 3

[0012] Example 3 Take 6 parts of filter mud, 5 parts of superphosphate, and 1 part of calcium magnesium phosphate fertilizer and mix them evenly to form a mixed fertilizer containing 11% of available phosphorus.

Abstract

The invention relates to a recycling and utilizing technology of waste filter mud produced by a sweet potato winery. A conditioner is added into filter mud which is not dried, a powdery or granular compound fertilizer with excellent physical properties is made by stirring and mixing for reaction, and the right amount of nitrogen, phosphorus, potassium, rare earth elements and a plant growth regulator are further added for preparing various binary and ternary compound fertilizers containing the rare earth elements and the growth regulator, so that smelly filter mud is turned into the powdery or granular fertilizer to solve the problem of environmental pollution caused by the filter mud, and the fertilizer has obvious economic benefits and social benefits.

Description

technical field [0001] The invention relates to the recycling technology of the filter mud produced by the sweet potato winery, which is suitable for making the filter mud produced by the sweet potato winery into mixed fertilizer and compound fertilizer. Background technique [0002] my country is the largest producer of sweet potatoes in the world. The perennial sweet potato planting area is 75-80 million mu, accounting for 4.2% of the total cultivated land in my country. The total output is about 80%. The filter mud produced by the sweet potato winery, as the waste residue produced by the sweet potato winery, contains high organic nutrients and is a good organic fertilizer. Therefore, the treatment of filter mud has become an urgent problem to be solved. The use of filter mud to develop and produce organic-inorganic mixed fertilizers has important practical significance for the development of circular economy. However, due to the high water content of the filter mud, the ...
