Abstract
In this article, waste water from metal processing enterprises and its composition, physical-chemical properties, atmospheric air and soil mineral composition are studied. In addition, the amount of micro and macro elements in the waste water was checked in relation to the permissible concentration. Currently, the main problems of industrial enterprises are to improve phosphating solution processes, reduce the amount of waste, save raw materials and fuel, develop measures to avoid waste in production, new high-performance technologies, waste-free and low-waste technologies. consists of implementation.
