Achieve true zero-emission wastewater treatment
Thread Content
**Wang Kaijun from the Engineering Technology Center for Environmental Protection Technology Management and Assessment said at the \"2015 (9th) Environmental Technology Industry Forum\" held in April this year that the introduction of the Water Pollution Control Regulations has brought endless opportunities to the environmental protection industry. Is it technically possible to achieve true zero discharge of industrial wastewater? Recent cases of water pollution have drawn attention, all involving the issue of zero discharge of industrial wastewater. Wang Kaijun said, \"At the level of industrial wastewater, some industries have reached a stage where they need to overcome difficult challenges; tough measures must be taken to address these issues. Moving forward, we must achieve zero discharge of industrial wastewater.\" ”How to achieve zero emissions? Wang Kaijun cited two cases. A pharmaceutical factory in Inner Mongolia was also exposed earlier; it used MVR combined with mist drying and incineration techniques there, and the results were very good. A paper manufacturing plant was also required to shut down a few years ago; however, after carrying out improvements and adopting electrically driven ion membrane technology, it achieved very good concentration results. Subsequently, MVR evaporation and crystallization were used to achieve near-zero emissions. Zhang Guoyun from Shijiazhuang Huafang Machinery Equipment Co., Ltd.: 15830976988 – We are here to serve you wholeheartedly.
Multiple-effect evaporation, along with MVR, are currently the more viable solutions for desalination in China. Membrane treatment is also an option, but to achieve true zero discharge, evaporation processes must be used in the later stages; RO treatment can be employed in the initial stages to reduce the volume of water that needs to be processed by the evaporators, thereby reducing investment costs.

This type of evaporation is not the same as that other type; which pharmaceutical factory in Inner Mongolia uses such effective MVR equipment? On the contrary, there is a very famous fine chemical products park that still uses open-air evaporation ponds for the evaporation treatment of high-salinity wastewater. If it is necessary to speed up or improve the evaporation efficiency, please contact me to discuss a mechanical evaporation solution. Q Mail: 346507310@qq.com
An idea is just an idea, and wishes are always beautiful. Some of our *employees have wild fantasies, which is an irresponsible attitude; they think about eliminating emissions when they haven’t even managed to meet the required standards. How can anyone believe in such a radical approach? It’s better to do something practical first; achieve compliant emissions before thinking about improving further.
With these facilities in place, the operating costs will also drive businesses into bankruptcy
There was a post earlier that discussed a lot about zero emissions being nothing but hype; everyone can take a look.
Zero emissions are theoretically entirely achievable, but in reality, it is far more difficult to achieve than meeting specified emission standards
Food should be eaten bite by bite, and tasks should be carried out step by step. Trying to run before one has learned to walk results in unsteady running.
It is unrealistic for a company to invest excessive costs in achieving zero emissions when operating with minimal profits
Enterprises exist to make a profit; although it isn’t their only goal, survival is the prerequisite for development. If survival itself becomes a problem and yet people keep making demands of them, there are only two possibilities: either the enterprise dies, or it resorts to fraud.
At present, some industries suffer from overcapacity and are facing low profits or losses; adjusting the industrial structure and carrying out transformation are urgent tasks that need to be addressed next.
