Abstract |
: |
Increased the importance of water in modern times to the degree in which the cause of the near future and long term in the Middle East in general and Saudi Arabia in particular. And where the water play an important role drainage in the management of water resources as an alternative to fresh water in agriculture and thus can be edited sources of fresh water to supply the various communities with drinking water. And thus contribute to re-use treated wastewater to achieve many of the economic benefits of water supply.
We have been doing six flights to take samples of sewage water from Mecca, where samples were taken from the wastewater within and outside the end of each month in order to estimate the efficiency of the plant in wastewater treatment in terms of natural properties, chemical and microbiological of the water where it was found that trace elements ( iron Fe, zinc Zn, manganese Mn, copper, Cu) and toxic elements (Pb Pb, chromium Cr, and Ni Ni) as well as the numbers of bacteria in the colon college and fecal as well as the requirement of oxygen chemical (COD) and the requisite oxygen Alkimouhaoa (BOD) in wastewater leaving the treatment plant is much higher than the limit Top set by the FAO, FAO, 1985, the Ministry of Agriculture and Water MAW for agricultural use.
As for the impact of irrigation in different concentrations of wastewater leaving the treatment plant in Mecca on the growth and productivity of the crop alfalfa and Sudan grass and their content of major elements (nitrogen, phosphorus, potassium, calcium and magnesium) and trace elements and toxic it has been found that with increasing irrigation at concentrations increasing from sewage treatment first (100% ordinary water + zero% sewage) and even treatment of the Fifth (zero% ordinary water and 100% wastewater) Adjei to a gradual increase morale in the values of productivity (green feed and fresh dry) and characteristics of the crop plant alfalfa and Sudan grass and increased their content of major and minor elements and toxic as well as their content of bacteria in the colon of fecal and total. |
