No waste or zero waste, no waste is common. The treated water is recycled, and the ingredients that affect the reuse are naturally present in the waste. In addition to the components that can be used directly, the common treatment methods of waste residue are evaporation pond and landfill. But no matter what kind of terminal is actually not disposal.

Although landfill disposal waste is still the mainstream of our country, but for the "zero discharge" this is obviously a higher requirement for the processing technology of environmental benefits, if only to this step actually not walked the whole. Because the waste residue of zero discharge process has strong solubility, it is easy to cause two pollution in the process of landfill. For example, the byproduct of coal chemical industry because of the complexity of the composition of the complex as a hazardous waste treatment, and its output is great, but there is no corresponding hazardous waste Center for disposal.

The successful experience in China also has a lot of salt for wastewater reuse of the case, such as the Inner Mongolia Wuhai energy and chemical company in the production of mixed Mengxi 2660 tons of salt products. Not only can solve the problem of part of the waste residue, but also directly bring the benefits, you can reverse the high cost of zero emissions treatment equipment brought about by economic concerns.
