Description

A device for removing suspended solids from ammonium nitrate wastewater

technical field

The utility model relates to the technical field of packaging machinery and equipment, in particular to a device for removing solid suspended matter from ammonium nitrate wastewater.

Background technique

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 nitrogen.

The existing pretreatment process adopts a combined mode of primary melt-blown filter element filtration and secondary ceramic filter element filtration. The operating cost of this filtration device is relatively large, and the suspended matter content after treatment does not meet the solid content requirements of electrodialysis feedwater, which will cause electrodialysis membrane clogging, reverse osmosis membrane efficiency decline, cleaning frequency increase, and manual labor intensity increase , the maintenance cost of the electrodialysis membrane increases, and the most critical thing is that the electrodialysis treatment capacity gradually declines, which will inevitably lead to the discharge water quality not meeting the standard of ammonia nitrogen content.

According to incomplete statistics, when most ammonium nitrate production plants use electrodialysis to treat ammonia nitrogen wastewater up to standard discharge or reuse, the suspended matter content in the condensate at the inlet of electrodialysis under the existing process conditions is generally higher than 10 mg/l, and some are as high as several hundred Even thousands of milligrams. If high concentration of suspended solids is maintained in ammonia nitrogen wastewater for a long time, electrodialysis membrane and reverse osmosis membrane will be clogged and polluted, the product water volume will decrease, the desalination rate of the membrane will decrease, and the pressure difference between feed water and concentrated water will increase, that is, the flux of the membrane will decrease. , the life of the membrane is shortened, and the maintenance cost is increased, which brings immeasurable losses to the enterprise.

However, the existing ammonium nitrate wastewater solid suspended solids removal device is relatively simple, and the removal device cannot quickly and effectively remove the suspended solids, thereby affecting the treatment efficiency of ammonium nitrate wastewater.
