ASPECTS WITH REGARD TO THE EFFECTS OF MOTOR VEHICLE ENVIRONMENTAL POLLUTION – A case study
Pollution can be considered a major assault on the environment caused by modern man. Air pollution caused by industrial activities and road traffic has a significant impact on the health of the population, especially on those who are living in urban areas, more exactly for 80% of Europeans. It involves the emanation of organisms, which release harmful substances into the atmosphere. The amount of pollutants emitted into the air we breathe was greatly reduced once the EU has introduced policies and measures addressing air quality in the 1970s. Design and implementation of policies to address this complexity is not an easy task.

32-56 OPTIMIZAREA TOPOLOGICĂ A STRUCTURILOR ÎN INGINERIE

TOPOLOGICAL OPTIMIZATION OF THE STRUCTURE IN ENGINEERING

 

Nowadays the rapid development of the industry required use the optimization method. First part of this study shows the structural optimization method used in mechanical enginnering, being made a detailed explanation of the iterative optimization process. In the second part of the paper is presented the CAD modelling and the topological optimization of the holder used in mechanical engineering. the results of the optmization study and the conclusions are presented at the end of this paper.

30-62 STUDII PRIVIND MONITORIZAREA STAŢIEI DE EPURARE HUEDIN PRIN PRISMA PARAMETRILOR DE CALITATE AI APEI

MONITORING STUDIES OF SEWAGE TREATMENT PLANT
FROM THE CITY OF HUEDIN THROUGH THE PRISM
OF WATER QUALITY PARAMETERS
The aim of this paper is the evaluation of wastewater from the point of
view of the quality parameters and establishing the efficiency of the Huedin city
treatment plant, which was rehabilitated in 2013. The main indicators of the
water quality track and review both the treatment plant at the entrance and exit
for the period January 2012-December 2015, referring to the biochemical
consummation of the oxygen-CBO5, total suspensions, ammonium-NH4,
chemical oxygen demand – CCO-Mn, pH of the water, detergents, a fixed
residue, total nitrogen, total phosphorus and CCO-Cr. Analyses carried out and
processed into monthly and yearly averages for these indicators revealed that
after the modernizations of the treatment station, they are all of the regulations
currently in force concerning the conditions of wastewater discharge.
