Outer operation harmless treatment after reason, air-flotation system water outlet supplies elevator pump to be lifted into multi-medium filtering into intermediate pool is temporary
Tank.
Multi-medium filtering tank is used to filter out in waste water there is very small amount suspended particulate substance, it is ensured that subsequently RO systems is long-term steady
Fixed operation.The regular backwashing water of multi-medium filtering tank returns to wastewater equalization pond and come out again, it is to avoid the generation of secondary pollution.
RO reverse osmosis units go most of soluble salt in water removal by reverse osmosis unit using the characteristic of reverse osmosis membrane
Point, small soluble molecules organic matter etc..At a pressure sufficient, water inlet becomes pure water by permeable membrane, and can not lead to
The impurity concentration crossed in the concentrated water side of film gradually increases, and is finally discharged in concentrated water form.RO reverse osmosis units press reverse osmosis in using
Saturating and high pressure counter-infiltration two steps ro device, enters high pressure counter-infiltration by middle pressure reverse osmosis concentrated water and carries out minimizing processing.It is high
Pressure reverse osmosis concentrated water is evaporated crystallization treatment, the outer innoxious place of operation of evaporator crystalline solid after collecting into MVR evaporators
Reason.
Although reference be made herein to invention has been described for multiple explanatory embodiments of the invention, however, it is to be understood that
Those skilled in the art can be designed that a lot of other modification and embodiment, and these modifications and embodiment will fall in this Shen
Please be within disclosed spirit and spirit.More specifically, can in the range of disclosure, drawings and claims
A variety of variations and modifications are carried out with the building block to theme composite configuration and/or layout.Except to building block and/or layout
Outside the modification and improvement of progress, to those skilled in the art, other purposes also will be apparent.
