Abstract:
نظرا لما لمياه الشرب من اهمية كبيرة في حياة الانسان وضرورة ان تكون هذه المياه ضمن مواصفات ومعايير خاصة, فضلا عن ظهور العديد من مشاكل تلوث مياه الشرب في مختلف مدن العراق. دعت الحاجة لاجراء هذه الدراسة لبيان مدى صلاحية مياه الشرب المنتجة من مشروع تصفية ماء | Owing to the drinking water of great importance in human life and it is important to be under the specifications and standards, as well as the emergence of many of the problems of contamination of drinking water in various cities of Iraq. Needed to conduct this study to demonstrate the viability of drinking water produced from the project filter water Karkh (which is the largest project the liquidation of water in the Middle East, it is feeds many of the cities of Baghdad, on the side of Karkh) and compare the specifications of Iraq and the global standard for drinking water in order to investigate the potential weaknesses in the project and study the possibility of the development of such large projects as a first step to improving the situation of drinking water in Iraq. So were the tests, physical, chemical and biological common to drinking water in the project and divided into four main stations, namely, (station socket raw water, sedimentation basins secondary sand filters, pumps, distribution of drinking water), including nine stations secondary starting of the month of October - 2010 to July - 2011.The results showed high values of turbidity, and electrical condactivety and pH, and dissolved oxygen, and biological dimond of oxygen, and alkalinity, and total hardness, calcium hardness, magnesium hardness, chloride, phosphate, nitrite, silica, fluoride, sodium, potassium, and heavy metals, namely, (iron, copper and cadmium, nickel, lead, chromium and zinc), and the total numbers of bacteria, and total coliform bacteria, the fecal coliform bacteria and E. Coli in drinking water for most of the stations in the Alsta spring and low concentrations in summer and autumn.Values for water temperatures between (4 - 37.5) c, as recorded differences significant between the months of winter and spring, summer and autumn, and the values of brownish discharge ranged between (250 - 0.3) NTU as it showed the differences of the moral high values of turbidity in the winter and fall in the summer and fall in each stage of the treatmant with it, and the values of electrical conductivity was between (520 - 895) Micro Siemens / cm 3. The water Alnehrualcherb in the project was registered as a weak base pH values between (9.7 to 1.7), and it was well ventilated, as the oxygen values were high in the winter months registered clear monthly variation ranging between (5.14 - 2.3) mg / L, either values biologicaldimond of oxygen were values between (4.4 - ND) mg / L and found that basal total stations ranged from every stage of the liquidation potential in increasing concentrations of dissolved oxygen, between (160 - 100) mg / L, and found that drinking water hardness too, as that the values of total hardness ranged between ( - 215 335) mg / L as suited their values directly proportional to both the calcium and magnesium hardness ranging between (197 - 139) and (31.472 - 16.128) mg / L, respectively, while for the values of the chloride ranged between (69 - 25) mg / l, while the fluoride has recorded values ranged between (15 - 0.05) mg / L, with values ranging between sulfate (169.2 - 90) mg / L, free chlorine residual values ranged between (4.18 - 1.1) mg / L, and materials for suspended solids ranged values between (84 - ND) mg / L proven contribution stages of liquidation, all in the rates of removal of different, either TDS fluctuated values between (545 - 315) mg / L, with log Aluminum values ranged between (0.98 - 0.01) mg / L, but for the potassium values ranged between (3.2 - 2.15) mg / L, and sodium values ranging between (6.31 to 3.21) mg / liter.As for the concentrations of heavy metals did not detect any significant concentration of heavy metals measured except for iron ranging between concentrations (9.2 to 8.1) mg / L, so after the industrial plants that contain the droppings of these metals. The nutrient values were recorded between nitrite (0.024 - 0.001) mg / Trosgelt nitrate values between (1.7 - 0.16) mg / l, recorded between ammonia (0.54 - ND) mg / L, placed at either phosphate values ranged between (0.26 - ND) mg phosphorus atom - phosphate / L, while for the values of silica fluctuated between values (5.12 to 5.1) mg atom of silicon - silica / liter. As for the study of signs bacteriological ranged the total numbers of bacteria in air through (24) hours between (555 - 0) × 10 cells / 1 ml, and ranged in numbers for a period of (48) hours between (1186 - 0) 10 × cells / 1 ml, while for the numbers of total coliform bacteria fluctuated between (1700 - 0) cells / 100 liters, and fecal coliform bacteria, they ranged (1100 - 0) cells / 100 ml, and the E.coli bacteria, the numbers fluctuated between (1100 - 0) cells / 100 ml. For to match the drinking waterproduced from the projects liquefaction research found matching the values and concentrations of brownish, and connectivity electrical and pH, and dissolved oxygen, and the requirement is vital for oxygen, and basic college, and chloride, and ten college, and magnesium, nitrite, phosphate, and the total numbers of bacteria, and the numbers of total coliform bacteria, and fecal coliform bacteria and E Coli, and silica with the standard specifications for drinking water the Iraqi and global at all stations.While the study results show non - conformity of calcium concentrations in this study with the standard specifications for drinking water of Iraq and the world.
