Operational analysis of the biological treatment unit's ultraviolet-wave disinfection method for wastewater outflow
Abstract Wastewater can be contaminated with all kinds of microorganisms and small organisms, including bacteria, parasites, fungi and viruses. Therefore, it can be said that biological pollution is one of the most dangerous pollutions. These types of pollution can endanger human health and the envi...

| description | Abstract Wastewater can be contaminated with all kinds of microorganisms and small organisms, including bacteria, parasites, fungi and viruses. Therefore, it can be said that biological pollution is one of the most dangerous pollutions. These types of pollution can endanger human health and the environment. In this study, industrial wastewater disinfection has been investigated in a laboratory pilot. In this study, ultraviolet waves have been used for wastewater disinfection. In this research, treatment indicators such as wastewater pH, phosphate, nitrate, biological oxygen and chemical oxygen, organic carbon, and wastewater turbidity have been investigated. The results of this research show that if 4.5 g of dry ice is added to the wastewater entering the disinfection unit, the pH of the wastewater will decrease to about 7.9. The results presented from the disinfection unit show that the amount of chemical oxygen demand and biological oxygen demand have decreased by about 35% and 20.3%, respectively. The results of this unit show that the amount of phosphate and nitrate has decreased by 61.3 and 71.9%, respectively. Laboratory results show that the TDS of wastewater has decreased from 600 to 451 mg/l. |
