Dragomir Stefan1, Dragomir Georgeta2
Abstract. The problems related to the protection of the environment by acuity in particular as a result of the
local pollution of the environment factors by the industry and agriculture or by the population centers, as well
as of a trans boundary pollution, which have led to the disturbance of ecosystems and the worse the living
conditions of the people. The use of chemical substances in more and more in the technological processes
advertise special measures concerning the protection of the environment. A major problem is the purification
of industrial waste water.
Keywords: coating industry; industrial water cleaning
1. Introduction
In the framework of this work shall be submitted to a solution of the cyanides waste water treatment
plant from galvanic industry (section accessories).
The removal of the pollutants existing results in the effluent purification stations mechanical-
biological waste water implies the use of the effects of the processes of the electrolysis to resolve the
issues related to the addressed.
A series of conditions covered locally in Romania by the technical rules of protection of waters
(NTPA001 and NTPA002), and on the European plan for the Member States by the Directives
KEPCO no. 271/91, no. 676/91 are designed to fit within the limits acceptable level of pollutants in
the effluent.
NTPA- 001 refers to the waste waters of any kind, namely to waste water, waste, waste water
industrial, sentenced to life imprisonments, or lump, tipped by systems arranged the fire from the
technological processes its own, as well as the sewage joint venture, which have or have not been
cleaned. The values laid down in these norms are maximum values are admissible.
NTPA-002 concerns the quality of waste water, from both social activities or economic in nature,
which is to be the exhaust in the networks of the sewerage of localities and those directly in the
treatment plants.
