| Abstract | ||
| This study aims at finding out the possibility of using rice husks in the treatment of gray water resulting from the hands washing sinks of Rusafa side school of Baghdad, then useing it to irrigate plants in schools and improve the properties of soil to increase the growth of plants and get rid of them without any environmental or economic damage. Al-Sa'adah Primary School has been chosen to execute the research during 2015. Two experiments have been carried out: the first is in the laboratory to know the possibility of using the husks of rice in the treatment of gray water with the column system, and the second is a biological one to know the possibility of using the husks of rice to improve some properties of degraded soils by using the experiment of planting plastic pots. The randomized complete block design RCBD has been used with three replications. The results of the laboratory experiment show that gray water quality in all selected schools are good and non-saline and do not require secondary treatment, but only primary treatment by using husks of rice for filtering and clarifying from suspended solids and large species then can be used for irrigation. While the results of the biological experiment show that the addition of husks of rice to the soil has lead to the increase of organic matter, water conductivity and total porosity as (7 gm.kg-1) ,( 2.46 cm.hr-1), and 44.14% respectively. Decreasing the bulk and particle density to (1.20gm.cm-3), (2.55gm.cm-3) respectively, and thereby improves physical and chemical properties of the soil which in turn is reflected in the increased growth of plants in the school and thus preserves the environment from pollution.. | ||
