Description

technical field

[0001] The invention relates to the field of environmental protection equipment, in particular to zero-discharge recovery equipment for advanced treatment of heavy metal wastewater. The present invention is mainly used in the recycling project of wastewater containing heavy metal ions and heavy metal ions, the recycling project of production wastewater containing salt, the recycling project of mixed bed and anion-yang bed regeneration wastewater in pure water preparation stations, and the desalination recycling project of other projects. Use engineering.

[0002] The single device (pressure water purifier) ​​in the present invention can be used as the main treatment facility of the water supply purification station, directly treat surface water such as river water and reservoir water into production water, and the ultrafiltration device can be used as the depth of various reclaimed water treatment Handle equipment. Reverse osmosis can be used as pretreatment ...
