Enhancement the efficiency of the wastewater treatment system of Suan Sunandha Rajabhat University by using the relation between BOD and COD values

Abstract

          A study on the optimization of wastewater treatment system of Suan Sunandha Rajabhat University by using the relationship between BOD and COD. The objectives of this research were study to the relationship between BOD and COD of wastewater treatment system and to find ways to improve wastewater treatment system of Suan Sunandha Rajabhat University. The 160 samples were analyzed BOD by acid modification method, 20°C 5 dayand COD using potassium dichromatemethod. The relationship between BOD and COD was determined using the Correlation and the optimization of the wastewater treatment system by interviewing the wastewater management experts.

          The results showed that BOD The average water influent was 22.28 milligrams per liter. Average water influent was 16.09 mg / L. The average water intake was 6.17 mg / L. The average water content was 4.51 mg / L. The COD was 36.53 mg /L. Average water content was 25.95 mg / L. Water content is 10.20 mg /L. The results of the study showed that the BOD and COD were correlated with water intake and discharge time. And have a relationship. The optimization of the wastewater treatment system by collecting COD samples continuously during the system improvement and calculating the BOD by the equation derived from the study. Well of the system, then operated by Controlling the amount of water into the wastewater treatment system. Increase the amount of microorganisms. And add other nutrients to the wastewater treatment system. Control the amount and flow rate of wastewater. It should be appropriate for the amount of wastewater generated and the rate of flow of wastewater. Control the appearance of wastewater entering the system does not contain toxic or heavy metals, these substances will inhibit the operation of the system.
