Abstract

The invention discloses a process for removing suspended solids in ammonium nitrate wastewater. The process is characterized in that a system is provided with a coarse filter and two precision filters, one precision filter is started and the other precision filter is standby, and when one precision filter enters a filtering program, the other precision filter is regenerated or standby. The processeffectively solves the problem of incomplete removal of suspended solids in the process steam condensate, micron-sized suspended solids in the condensate can be effectively removed through the process, and the removal efficiency of solid particles with the particle size of 1 micron or above reaches 99% or above.

Description

technical field [0001] The invention relates to a process for treating a large amount of high ammonia nitrogen process condensate wastewater solid suspended matter produced in the ammonium nitrate production process. Background technique [0002] In my country's KT ammonium nitrate production plant, the ammonia nitrogen content of the process steam condensate is generally high, which makes this part of the condensate unable to be reused or discharged. At present, electrodialysis + reverse osmosis membrane technology is used to treat this part of the condensate, and the ammonia nitrogen content can be less than 5mg / l. The prerequisite is to do a good job in the pre-treatment stage: pH adjustment, condensate cooling, and removal of suspended solids. Especially in the process system of electrodialysis + reverse osmosis treatment of high ammonia nitrogen wastewater, the removal of suspended solids in condensate is an important link in the clean and standard treatment of ammonia...
