المستخلص: اجريت الدراسة في قسم علوم الحياة - كلية التربية - جامعة تكريت من شهر تشرين الثاني 2010 الى شهر تموز 2011 ? وكان هدف الدراسة هو معرفة بعض الصفات الفيزياوية والكيمياوية للمياه المطروحة من شركة مصافي الشمال/بيجي وامكانية استخدامها لري بعض المحاصيل الزراعية ب | This study was conducted at the Department of Biology in the College of Education - University of Tikrit. The study aims at estimating some physical and chemical characteristics of water raised from the North Refineries Company / Baiji and can be used to irrigate some crops after treatment with a number of physical methods. It also aimed at estimating some heavy elements and their impact on the growth of plants that have been studied (tomato, eggplant, sweet pepper, hot pepper). The region from which samples have been brought of the area was Albu Juwaree village that is located in the city of Baiji and adjacent to the company. Besides, it occurs near wide agricultural areas. After estimating some physical and chemical characteristics of water, soil, and the proportion of oil waste, qualities of plants were studied as well as the assessment of (carbohydrates, proteins) and some of the heavy elements and their effects on the growth of those plants.The results showed that the water of industrial waste led to a reduction in the proportion and natural growth of plants. The most affected seeds were the seeds of sweet pepper, where the total percentage of germination was(0%) when infected %)100) and the least affected seeds were the seeds of tomato, where the total percentage of germination seeds was (80%) when water is contaminated (100%). The treatment by filtering has achieved the best germination of seeds of tomato and sweet pepper, where the ratio was (100%). It turned out that contaminated water has prevented the natural growth of those plants in respect to the number and the size of leaves, the length of roots and the weight of fresh and dry leaves. The methods of physical treatment showed that lightening (25%, 50%, 75%) made to the contaminated water led to the removal of the significant effects, especially when lightening was (75%).The results indicate that there is no significant differences in the lengths of the roots of tomatoes and eggplants, except for the root of hot and sweet pepper.While the heavy elements, which was part of the study in this research, beginning with cadmium was at its highest value at the treatment by filtering and less value in (100%). Through the study it was found that the percentage of lead in all studied plants were (0.00) ppm. The Results showed that the contaminated water led to the reduction of the proportion of carbohydrates with the increase of pollution(%100), where the least proportion of carbohydrates was at the treatment by filtering. The results also showed a decrease in protein concentration with the least proportion at lightening and less value in. (25%)The results showed that the water content of contaminated industrial heavy metals studied (cadmium - lead - copper - zinc - nickel) has decreased at all treatment when treated by filtering, as well as for the remaining elements, except lead, which was (0.00) in all plants and all lightening ratios.The results of this study show that treatment of contaminated water with industrial oil waste by physical methods led to minimizing the negative impacts of such water in reducing the percentage of germination and the reduction below the natural growth compared with non - treatment water and showed that the best way of treatment for the best growth of plants were lightening with (75%) and treatment by filtering. The best response to the treatment was tomato and the most resistant to pollution were (tomato and eggplant) and the most affected by contamination and least resistant was sweet pepper.

This technique considered a modern technique in this field.Physical, chemical and biological characteristics of the manufactured sludge were determined and compared with organic fertilizers (I.O.F) imported from republic of Estonia (Available in local markets).T.R.D technique induced dewatering of the treated sludge at ratio48.5 - 61.5% and producing highly sterilized organic fertilizers which was free of pathogenic organisms(bacteria, worms and eggs) with high chemical characteristics comparing with those imported from Estonia. Manufactured organic fertilizers M.O.Fs have allow acidity pH ranged between 7.5 - 7.7 ,. electrical conductivity at range 1630 - 1873, organic matter at ratio 4.56 - 5.35%, with a moderate concentrations of Pb, Cd, Zn.The concentration of N and K was 1.8, 5.96% respectively while the concentration of phosphorus are 350 ppm. Three levels of M.O.Fs were used for corn plants(5, 10 and 20ton/acres). Results showed that all these levels significantly induced increasing for some physiological and morphological characteristics of corn plants compared with those treated by I.O.Fs or control plants. The vegetative dry weight of corn plants fertilized by M.O.Fs were 23.95gm/plant compared with 16.3 and 5.3 gm/plant for plants fertilized by I.O.Fs and control respectively. (M.O.Fs) induced significant increase in nitrogen concentration compared with plants fertilized by I.O.F and control while the concentrations of Pb, Cd, Zn were not affected by using of M.O.Fs on the other hand Pseudomonas aeruginosa and Escherichia coli were contributed in reducing and removing some of pollutants from the sludge at three incubation periods (30, 60 and 90 day). These two species caused significant decrease in pH and EC of the sludge, P. aeruginosas showed the highest removing ratio of nitrogen (93.1%). The cooperation of the two species caused high removing ratio for the Total organic carbon(87.72%) at 60 days and organic materials (90.68%) at 90 days of incubation also showed high removing ratio for phosphors 100%) at 90 days of in cubation.) These two species also caused high removing ratio for pb, Cd and Zn at30 days and P. aeruginosa was more effective in removing Pb, Cd and Zn from the sludge then E. coli.
