China is a large country in the coal chemical industry. The large-scale development of the coal chemical industry has brought about huge environmental problems. The main components of coal chemical wastewater are coking wastewater, coal gasification wastewater and coal liquefaction wastewater. The components are very complex. COD, ammonia nitrogen, and phenol high content, and also contains fluoride, thiocyanide and other toxic substances, coal chemical wastewater treatment technology has become an important factor restricting the further development of China's coal chemical industry.
Features of coal chemical wastewater:
Complex composition and high concentration of pollutants
Contains toxic substances and harmful
Poor biodegradability
The zero liquid discharge of coal chemical wastewater is a special membrane application field emerging in recent years. Generally, it is required to achieve zero liquid discharge of wastewater. Jiarong cooperated with domestic engineering companies in the domestic coal chemical wastewater industry to develop and implement a number of large-scale coal chemical wastewater zero-emission projects
The solution provided by Jiarong is mainly directed to the concentrated water of traditional reverse osmosis. The main process section includes pre-filtered hardness removal tubular membranes, salt and nanofiltration membranes and high concentration special reverse osmosis (STRO / DTRO / MTRO) processes. And can make complete sets of equipment according to customer requirements.
