Environmental problems in metal etching process

The liquid metal etching processing, as a general rule, be phosphoric acid and hydrochloric acid, the concentration is bigger, need to deal with after to emissions, or caused to the environment pollution is immeasurable!Metal etching processing influence factors in the process of acid, alkali and ferric trichloride, the waste paint should be properly handled, not casually.

Is commonly used for acid and alkali waste water neutralization method for processing, just the alkaline wastewater in metal etching process, also has the acid waste water, they can neutralize each other, will not, of course, just the acid-base balance, this is about to test PH value, lack what fill what, the PH value reached the requirements of discharge, but also clear away excess metal ions, after precipitation, water before discharge.The pollution of waste liquid of ferric chloride to the environment is mainly its image, where touched, where is a piece of yellow rust, very ugly, damage the environment.The waste coating should be canned by the processing unit recovery.For the treatment of waste water containing ferric chloride, the more common treatment method is to put in lime milk, which can not only neutralize the acid, but also precipitate the iron trivalent and other metal ions in the waste water, and agglomerate the impurities in the waste water.

In human life, as long as there is activity will cause varying degrees of pollution to the environment, according to the reasons, can be divided into industrial pollution, traffic pollution, agricultural pollution and life pollution, has contributed a lot in this kind of pollution to the environment pollution, at the same time, it is difficult to eliminate the industrial pollution, from the perspective of environmental protection and the survival of the need to consider, every processing enterprises in the process design to prevent pollution, protect the environment in the first place is very important.
