The invention relates to the technical field of chemical engineering and particularly relates to a production method for preparing a special fertilizer for dasheen from diammonium hydrogen phosphate by-products. By virtue of analyzing requirements on nutrient elements of the special fertilizer for dasheen and combining the defects existing in a preparation process of diammonium hydrogen phosphate products, the preparation process of diammonium hydrogen phosphate products is combined with a preparation process of the special fertilizer for dasheen so that the two processes are complementary, wastage rates of nitrogen and phosphorus and the discharge amount of waste liquid in the preparation process of the diammonium hydrogen phosphate products are reduced and the production cost of diammonium hydrogen phosphate is reduced; by controlling parameters in process steps, the purity of the diammonium hydrogen phosphate products can reach 96% and meanwhile an efficient special nitrogen-phosphorus-potassium complex salt combined-state compound fertilizer is provided for dasheen.

Production method for preparing monocalcium phosphate and by-product special fertilizer for black soybean
InactiveCN104326461AGuaranteed intermediate ionGuaranteed dihydrogen phosphateAlkali orthophosphate fertiliserAmmonium orthophosphate fertilisersControl releasePhosphoric acid
The invention relates to the field of chemical technique, especially to a production method for preparing monocalcium phosphate and a by-product a special fertilizer for black soybean. By changing coefficients such as temperature and the like of wet-process phosphoric acid preparation of monocalcium phosphate, purity of the product monocalcium phosphate is raised, and a compound fertilizer containing N, P and K combined forms can simultaneously be produced. By the method, purity of monocalcium phosphate can be raised, and the produced special fertilizer for black soybean has good absorptivity. Meanwhile, formaldehyde is added into a filtrate to prepare a controlled-release compound fertilizer. The produced special fertilizer for black soybean can meet nutritional requirements of each period of growth cycle. By the use of the compound fertilizer, yield of black soybean is raised greatly. The special fertilizer is an efficient compound fertilizer.
