يعود ظهور شجرة الزيتون إلى ماض سحيق ( ستة آلاف سنة ) وقد ارتبط نشؤوها بتاريخ بلدان البحر الأبيض المتوسط حيث لعبت منذ الأزمان الأولى دوراً هاماً في اقتصاد شعوب البحر الأبيض المتوسط
أجري البحث في مزرعة كلية الزراعة بجامعة دمشق عام 2017 . حيث تمت زراعة نبات القصب في أحواض بمعدل 4 شتول في الحوض الواحد وسقي بماء الجفت بتراكيز مختلفة
A research was carried out at Al-Sanouber research station in
Lattakia in 2013/2014 season ,The research included six treatments
with four replicates for each treatment. Six treatments used of
OMWW (0 , 10 , 20 , 30 , 40 , 50) l/m2. The OMWW has b
een
added 40 days before planting. Samples of soil have been taken
before adding OMWW, then after one and two months from
planting, and at the end of the season in order to make some
physical and chemical analysis and also to know the concentration
of some micro elements .
The aim behind this study was to isolate and characterize fungi from fermented olive
mill wastewater to determine the superior one that can resist high organic load and total
phenol of fresh Olive Mill Wastewater (OMW).
Two different media Czapak
Dox Agar (CzA) and Potato Dextrose Agar (PDA) were
used for identification of fungi by studying macroscopic and microscopic characteristics.
However, Aspergilluss sclerotiorum, Paecilomyces sniveus and Mucor nircinelloides had
had been identified .
After testing the isolates on fresh olive mill wastewater solid mediums OMWA1
(50%OMW), OMWA2 (75%OMW) and OMWA3 (100%OMW).
Whereas P. niveus proves that was the superior one, which can resist high
concentration of fresh olive mill wastewater.
3,4-dihydroxybenzoic acid is one of phenolic compounds that exists in olive mill waste water (OMWW) and different industrial wastewater.Commercially activated charcoal was studied as absorbent of polyphenols. The value of specific surface area was 73
6.7189 m2/g. Equilibriums of 3,4-dihyroxybenzoic acid from aqueous solutions on four different particle sizes of the adsorbent with diameters ranged A(1000-2000), B(500-1000), C(250-500), D(125-250)m was examined at different initial concentrations ofabsorbate. The experimental data were analyzed using the Langmuir and Freundlich isotherm models. Both the isotherm models fit the adsorption data. Monolayer absorption capacities Q0 calculated from Langmuir equation were (0.36, 0.23, 0.34, 0.35mmol/g) for the different granular activated carbon sizes (A,B,C,D) respectively. The values of constant Kf calculated from Freundlich equation were (0.75, 0.61, 0.76, 0.79mmol/g) for the four sizes of granular activated carbon (A,B,C,D) respectively.
The results show that the charcoal activated carbon can be used as absorbent for polyphenol compounds.
