Environmental issues in the production of compound fertilizers
Thread Content
At present, the environmental protection situation across the country is extremely severe, and the production of compound fertilizers is restricted. The best method for dust control is water washing for dust removal, but handling the washing liquid and sending it to wastewater treatment plants poses difficulties due to the high ammonia nitrogen content, making its treatment challenging.

Collected in cloth bags or electric fabrics for recycling
I wonder what good ideas President Cui has.
Can high-viscosity oil be sprayed to reduce dust?
Could you recommend some formulas for water-soluble fertilizers, so that washing water can be turned into water-soluble fertilizers for sale? Especially what to do with the water from the high-tower washing and granulation nozzles – I have no idea!
It’s a troublesome issue; the high humidity in the drying exhaust gases produced during ammonium carbonate production makes it even more difficult to handle. In the case of dust alone, it can be collected using cloth bags
The ammonia nitrogen level in the water used to clean the nozzles is very high, making it difficult to handle; phosphorus, on the other hand, is easier to deal with

Engineer Li used to work at Yangmei Fengxi; now he is retired but continues to contribute his expertise. There are current problems with drum granulation; the first one is the low ball-forming rate. The second is the harsh granulation environment. Third is the deterioration of the granulation cycle system due to excessive return material. Fourth, this vicious cycle leads to increased production costs, reduced batch output, and increasingly greater difficulties in granulation. To address the above issues, I have been engaged in the production and technology of compound fertilizers for a long time, and through certain technical methods, I have successfully resolved these five problems
