THE QUALITY OF WASTEWATER IN THE DAIRY INDUSTRY

摘要

The paper aims a comparative study of the parameters of dairy wastewater during three years namely a comparison of wastewater parameters before entering in the treatment plant and waste water parameters after treatment in the wastewater treatment plant. The indicators used to analyze the quality of wastewater from the dairy factory were: CCO-Cr,?CBO 5 , total suspensions, pH, chloride content, total nitrogen, total phosphorus, oils and fats. The purpose of monitoring is to produce information on the physico - chemical waste water, on treatment technologies efficiency, focusing on the disinfection process, to determine if the waste water is adequate or not in terms of the values of the relevant parameters set by law.
