Sinochem News recently, Huayang Group Nitrogen-based Synthetic Materials Co.
, Ltd.
's high-efficiency membrane concentration zero-discharge device-the reclaimed water reuse device produced crystalline salt, realizing zero discharge of industrial wastewater
.
After the high-efficiency membrane concentration zero-discharge device is operating normally, the company's daily industrial wastewater treatment capacity can reach about 1,200 tons
.
After this process has undergone the membrane concentration treatment in the front stage, the three-effect evaporative crystallization technology is used to separate the high-salt wastewater from the crystallization salt, which is reused to the synthesis and urea circulating water production line to achieve zero discharge
In October last year, the company introduced the domestic advanced level of industrial wastewater treatment technology and equipment.
According to the idea of "cleaning sewage, separation, quality treatment, and comprehensive utilization", it has constructed inorganic, organic, super reverse osmosis, evaporative crystallization, etc.
The reclaimed water reuse device of the system
.
In mid-April this year, they completed the installation of the device, began trial operation, and recently produced crystalline salt
