Abstract EN
In this study, the use of the modeling software GPS-X 6.1 specialized in the design of sewage treatment units.
To remove the phosphorus and nitrogen from the treated wastewater and make it identical to the Iraqi standards for the purpose of recycling and use in agriculture in the district of Al-Rumaitha in Al-Muthanna province in southern Iraq.
The effect of changing the temperature during one year on the quality of the water produced, and its effect on the efficiency of the treatment plant in the removal of phosphorus and nitrogen was studied.
Results show that a series of conditions of anaerobic, oxygen-oxygenated and aerobic reactors help to efficiently remove biological nutrients.
Concentrations of phosphorus compounds, nitrogen compounds, COD, BOD, and TSS were less than permissible environmental determinants.
Except for the release of phosphorus compounds during the summer (July and August) due to the sensitivity of phosphorus-containing organisms to the effect of temperature.
The increased concentrations of phosphorus produced in summer were processed by adding chemicals dosing (Al2(SO4)3 or iron) in various stages of the wastewater treatment plant and required dosage of alum in the range of 0.4-0.8 kgAl / kg P influent, depending on the dosage strategy.
