The agronomic aspects of some organic waste compost applications to sesame plants grown on sandy soil were investigated. Different rates and combinations from biosolids (BS), municipal solid waste (MSW) and water hyacinth (W) compost, incorporated with or without shale deposits (tafla) at 8%, were used to treat the sandy soil. Dry matter accumulation was used as an indicator of the effectiveness of such treatments on plant growth. In addition, the contents of nitrogen-phosphorus-potassium, chlorophyll, total protein, oil and carbohydrates were determined in plant tissue as physiological parameters. Heavy metal contents (Fe, Mn, Zn, Cu, Co, Ni, Cd, Pb) in seeds samples were determined. Results indicated that all compost treatments stimulated sesame growth and enhanced its pigment, carbohydrate and mineral contents. While the chemical constituents of sesame seeds (oil, carbohydrate and total protein) showed no variation when expressed as relative data (%), the absolute results expressed as gram per plant exhibited significant increases. The maximum levels (μg g−1) of tested metals in seeds did not exceed 226 Fe, 12.5 Mn, 81. 7 Zn, 23.7 Cu, 3.8 Co, 24.6 Ni, 5.4 Pb and 1.72 Cd, which are below the reported concentrations at which phytotoxicity could occur. 相似文献

The optimization of sewage treatment by the combination of high rate biological treatment with chemical coagulation to remove both organic and inorganic pollutants with special reference to phosphorus has been investigated. In an attempt to study the minimum biological treatment which will not adversely affect the efficiency of the combined system, three different organic loads, namely, 9.48, 20.0 and 27.85 BOD5.m?2d?1, were examined. The coagulants used were ferric chloride and alum. Calcium oxide was used as a coagulant aid with ferric chloride. The results obtained showed that the efficiency of the combined system was found to be slightly affected by the organic load. The combined treatment technique used in this investigation proved to be very promising in removing both inorganic and organic pollutants. 相似文献

ABSTRACT: The quality of ground water in any aquifer takes its final form due to natural mixture of waters, which may originate from different sources. Water quality varies from one aquifer to another and even within the same aquifer itself. Different ground water quality is obtained from wells and is mixed in a common reservoir prior to any consumption. This artificial mixing enables an increase in available ground water of a desired quality for agricultural or residential purposes. The question remains as to what proportions of water from different wells should be mixed together to achieve a desired water quality for this artificial mixture. Two sets of laboratory experiments were carried out, namely, the addition of saline water to a fixed volume of fresh water. After each addition, the mixture volume and the electric conductivity value of the artificially mixed water were recorded. The experiments were carried out under the same laboratory temperature of 20°C. A standard curve was developed first experimentally and then confirmed theoretically. This curve is useful in determining either the volume or discharge ratio from two wells to achieve a predetermined electrical conductivity value of the artificial mixture. The application of the curve is given for two wells within the Quaternary deposits in the western part of the Kingdom of Saudi Arabia. 相似文献

The oxidative stress in the digestive gland of the land snail Helix aspersa was considered as a bioindicator for atmospheric pollution with heavy metals from several industries and vehicular traffic in Kafr El-Zayat city. Regional means of heavy metals concentration of all sites were 0.71, 7.09, 0.71, 2.68, 41.44 and 18.01 mg kg−1 wet mass for Cd, Mn, Ni, Pb, Zn and Cu, respectively. In addition, the highest values of Cd concentrations were found 1.22 and 1.73 mg kg−1 wet mass in S1 (Potato International Center) and S4 (The Nile bank), respectively. Lactate dehydrogenase (D-LDH(and recorded lipid peroxidation (LPO) levels were significantly high in S1 and S2 (Traffic station). On the other hand, the highest activity of catalase (CAT) was found in S2 (194.04% of control), while the activity of glutathione peroxidase (GPx) reached the highest significant value in S1. 相似文献

Refinery wastewater from Moustorod oil refinery, Cairo, Egypt, was treated by chemical coagulation. This step was followed by rapid solid-liquid separation using flotation under pressure of 4 atm. A flotation tank was designed for this purpose. Gas liquid chromatography was used for determination and identification of hydrocarbon compounds in refinery wastewater. The treatment technique proved to be very promising for reducing the hydrocarbon compounds, as well as other pollutants, to a very low concentration. The results obtained showed that some of the hydrocarbon compounds were completely removed. 相似文献

Electrocatalytic degradation of Acid Blue and Basic Brown dyes from simulated wastewater on lead dioxide anode was investigated in different conductive electrolytes. It was shown that complete degradation of these dyes is dependent primarily on type and concentration of the conductive electrolyte. The highest electrocatalytic activity was achieved in the presence of NaCl (2g/l) and could be attributed to indirect oxidation of the investigated dyes by the electrogenerated hypochlorite ions formed from the chloride oxidation. In addition, contribution from direct oxidation could also be possible via reaction of these organic compounds with the electrogenerated hydroxyl radicals adsorbed on the lead dioxide surface. In the presence of NaOH, the electrocatalytic activity of the employed anode was not comparable to that in NaCl due primarily to the absence of chloride. This indicates that dyes degradation in NaOH occurs exclusively via direct electrochemical process. However, in H2SO4, the electrode performance was poor due partially to the absence of chloride from the conductive solution. The possibility of electrode poisoning as a result of growth of adherent film on the anode surface or production of stable intermediates not easily further oxidized by direct electrolysis in H2SO4 might also be accountable for the poor performance observed in this conductive electrolyte. Optimizing the conditions that ensure effective electrochemical degradation of Acid Blue and Basic Brown dyes on lead dioxide electrode necessitates the control of all the operating factors. 相似文献
