- Abstract
The wastewater dairy is one of the most sources for pollution of the environment due to dairy's high organic content. The main idea of this project has been starting the treatment of wastewater in the dairy industry. Based on the initial analysis that were performed there, we have identified the whey is the main problem of that pollution. Due to needed high capacity and high cost for treatment of the whey, this dairy decided to change the whey's flow, not discharge in the same direction with wastewater. It uses SBR (Sequencing Batch Reactor) system. This system fills and draws activated sludge for the treatment of water. The water is treated to remove undesirable components, and then discharged. The parameters which are measured for this treatment are physical and chemical parameters. The oxygen values are measured by the oxygen meter. Temperature and pH are measured by the thermometer and pH meter. Biochemical demand Oxygen and chemical demand oxygen is very important parameters for measurement. BOD analysis was performed by the Manometric method or Oxitop instrument. COD analysis were performed by the method 8000 based on DR 2800 Spectrophotometer procedure. Other chemical parameters are measured by DR 2800 Spectrophotometer procedures manual as well. Total suspended solids and volatile suspended solids were prepared by gravimetric method. According to the results obtained from those parameters, we can conclude the effect of treatment of wastewater in the aeration system. We have reached to decrease the values of those parameters leading those to desired values for dairy industry.
