Wastewater Management of Plastic Bag Washing Plant at Ubon Ratchathani University

Abstract

This research is a cross-sectional study. It aims to study wastewater management and the quality of the wastewater of the plastic bag washing plant of Ubon Ratchathani University. Data was collected using a wastewater management survey and laboratory wastewater quality analysis. The wastewater samples were collected at 3 points, the plastic washing process: the anaerobic digestion wastewater treatment pond, and the final pond. The study results revealed that 36.36% of the wastewater management requirements were met. It was found that the effluent quality passed 15 parameters, representing 88.23%, and the two parameters were not passed, pH and total dissolved solids (TDS), accounting for 11.77%, compared to the standard according to Announcement of the Ministry of Natural Resources and the environment on the determination of the standard for the control of sewage from the source of industrial plants industrial estate and the business district, 2017 and the water efficiency of the wastewater treatment of plastic waste washing plants Ubon Ratchathani University and the heavy metals does not exceed the standard, Therefore, solving the problem of effluent quality of the plastic waste washing plant should solve the problem at the source caused by the use of washing chemicals. And increase the water retention period. Check the water circulation system of the last well and set that the depth of the well should not exceed 2 meters.
