Abstract

       The experimental study in this laboratory. The objective is to study the efficiency of the wastewater treatment system of Sirindhorn College of Public Health. For example, in this study, water from the Oxidation Ditch of Sirindhorn College of Public Health. Water samples from the wastewater treatment system are collected at 5 points as follows Point 1 The water in the pumping pond is where the wastewater is collected Point 2 Water in the Oxidation Ditch Point 3 The water in the sedimentary tank Point 4 The water in the pond adds chlorine and Point 5 Water in the waste water pond to measure temperature, PH value, Settable Solids and chlorine value, and then take all 5 water samples to analyze in the Environmental Health Laboratory to find the DO BOD COD and Total Dissolved Solids Total Solids and Suspended Solids. Data were analyzed using descriptive statistics such as mean value. The results showed that Wastewater that has been treated by the wastewater treatment system of the Sirindhorn College of Public Health. Khon Kaen. There are quality that meets certain standards in accordance with the standards for sewerage control of Class A buildings of the Ministry of Natural Resources and Environment. Which the characteristics of water that passed the standard. The pH value at points 1-5 passed all criteria, with an average of 7.5, 7.80, 6.93, 6.63, 6.07, respectively. Total Solids values at point 5 passed the criteria with an average of 270.60. Total Dissolved Solids with an average of 212.60, point 5 Suspended Solids passed the average with 23.18. The 1st point COD passed the average of 189.60 and the 1st point BOD passed the average with 32.00 and the characteristics of wastewater which did not pass the standard criteria, namely the DO value before treatment. The second point did not pass the criteria, with an average value of 19.20. The DO values after the treatment point 2 failed the criteria with an average value of 19.50. Settable Solids value was not qualified with average value 10.00 and chlorine value was not qualified with <0.2.
