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
