دراسة تأثير مقدار و تركيز الملوثات في نهر الديوانية

الملخص EN

That the reduction of environmental pollutants in the river is one of the most important priorities for the production of drinking water.

In this study were selected river known as the Shatt al-Diwaniyah , to demonstrate the potential environmental impacts of various pollutants in the area from the Sunni, is north of the city, even in southern city of Diwaniyah, about (15 km) inside the city at (15) stations selected for the period from March 2008, until the end of October 2008.

Study included the measurement of suspended solids (TDS) to the waters of the Diwaniyah, with a measure of directional acid , electrical conductivity measurement, a measurement of dissolved oxygen.

The measurement of the concentration (nitrate, the need for chemical oxygen (COD), phosphate).

Showed the results of the study during the examination of the statistical analysis that there are weaknesses in the relations between the concentrations of pollutants in the plant (1), with the change in water temperature at all stations ranging between (25.95-31.78) m, respectively.

PH values with a range of constraints in all the stations ranged between (7.50-8.17).

Also recorded the electrical connectivity values ranged between (1333-1516) Maekerosemnz / cm, total dissolved solids (TDS) values ranging from high (774-875) mg / L, dissolved oxygen values ranging between (7.55-9.51) mg / L , the study recorded a high concentration of vital oxygen requirement beyond the parameters allowed in most of the stations studied.

Nutrients were also observed, which fluctuated in a narrow band and a clear concentration especially nitrate, which ranged between (8.01-16.10) Maekerowerem / liter.

The effective rate of the phosphate concentration is higher than the permissible limits according to the maintenance of river-1976 rate, in most stations.

Has also been observed through the statistical analysis that there is a small decline in the concentration of pollutants to the station with the same time.

Why all of this is due to the presence of rubber and textile factory, which put toxic chemicals as well as the presence Al-mbazl in addition to a fever hospital, and kidney of industrial waste into the river, raised, as well as abuses of the networks in the rain by the citizens living on both sides of river.

And most of the inefficiency of the main treatment plant as the existing amount of water entering the plant exceeds design capacity to the plant, this water is not in conformity with the emerging environmental determinants of sewage discharged to rivers, the river level in the study period was less from previous years.
