| Abstract | ||
| Industrial wastewaters are the serious problems which nowadays effect the environment, the process of treat them as well as the disposal of their negative impacts are numerous and different. The access of these industrial residuals to the soil by any way will attain the soil safety and their properties changing and consequently the safety of structures constructed or will be constructed on such soil is the major subject of researchers .This study dealt with the influence of disposed industry wastewater on chemical and engineering properties of the soil by soaking soils specimens with samples of this water, also this study includes the effect of gypseous soil as an infiltration medium on the chemical properties of dairy wastewater, which infiltrated through a column of gypseous soil .It was transported gypseous soil samples from Tikrit region with gypsum content at (31.68%) , where this research contain two stages, the first one contains soaking these gypseous soil samples in basin of dairy wastewater for (15, 30 & 60) days. At the end of each period, the soil samples taken for conducted the engineering and chemical tests.The second stage is summarized by leaching the dairy wastewater through soil column, tests were conducted (specific gravity, Atterberg limits, compaction, shear strength parameters, consolidation, collapse, gypsum content, total soluble salts, organic maters and pH) also it was conducted for leaching dairy wastewater .The results showed the soil exposed to soaking were changes in soil and infiltrated wastewater properties, In regards to the impact of soil on the infiltrated wastewater characteristics it was showed where leaching periods increased, the pH value for dairy wastewater reduced also the COD, phosphate PO4 and nitrates NO3 , while the values of chlorides CL and sulphates SO4 were increased . | ||
