Abstract

Introduction: The main aim of this study was quality and quality analysis of
electronic and chemical industrial wastewater in the mega city of Tehran. This
research was conducted in two phases, first: water consumption and second:
quantity and quality analysis of wastewater in such industries.
Methods: Right now there are 59 chemical and electronic industries with over 50
personnel in Tehran. 18 factories among these industries were randomly selected.
For wastewater quantity analysis, the rate of water consumption and waste water
generation were considered. For waste water quality analysis, Biomedical
Oxygen Demand (BOD), Suspended Solids (SS) were considered in these
industries.
Results: The results show that among these industries, plastic factories with
40.3% of total water consumption and 31.6% of total wastewater production is
the most water consuming and wastewater generating factories in the industrial
section. On the other hand, electronic industries with 3% of total water
consumption and 3.4% of total wastewater generating have the lowest from the
pollution point of view, detergent producing industries with 44% of total BOD5
and 41% of total SS have the highest portion in the total pollution load by
industry. On the other hand, electronic industries with 0.5% of total BOD5 and
battery producing industries with 1% of total SS have the lowest degree among
the industries.
Conclusion: The final conclusion shows that chemical and electronic industries
discharge a high load of pollution to the environment which can have a great
reuse potential. Since these industries are very close to the agricultural loads, the
condition for such reuse exists.
