| 摘要 |
<p>The invention relates to a method and apparatus for surface treatment of objects made of metals such as iron and nonferrous metals and/or plastics, composite materials and the like in a pretreatment plant for subsequent painting and/or powder coating in an appropriate plant having a water pretreatment plant connected downstream. In order to enable the disposal of waste water to be avoided altogether or reduced to a very small quantity of waste water in this, the invention proposes that a waste water treatment plant is connected downstream of the plant, in which treatment plant industrial evaporation processes are carried out, the energy for which originates from a process which is directly or indirectly connected to the painting and/or powder coating plant. This "waste energy" originates, for example, from warm air which is released by the painting or powder coating plant.</p> |
