Effect On Soil Physical Properties And Salinity Because Of Reclaimed Water Irrigation In Fermentation Industry

Reclaimed water utilization is an important means of sewage reuse,which can meet the requirements of both development and environmental protection.On the one hand,fertility elements in reclaimed water have beneficial effects on soil.On the other hand,harmful substances in reclaimed water also have adverse effects on soil,and the effects of different irrigation water and water quality on soil are different.Fermentation industry for research of reclaimed water(after fermentation industry waste water treatment of recycled water)for the possibility of soil,irrigation,this study used in Inner Mongolia industrial high salt reclaimed water,clear water,1:1 mix water for irrigation water,sand,silt loam and loam soil for the participants,and 1.1 L and 1.4 L and1.6 L irrigation water mixed orthogonal analysis,to analyze the different water quality,irrigation water on the impact of soil physical and chemical properties,the conclusion is as follows:(1)the influence of different irrigation amount and water quality on physical indicators,namely soil bulk density,water content and porosity,tends to decrease with the extension of irrigation time.The changes of irrigation and water quality have no significant influence on soil physical properties(2)the effect on soil p H and conductivity increased with the extension of irrigation time,and the change of irrigation water and water quality had a significant difference in soil conductivity.There are significant differences between chloride ion,calcium ion,sodium ion,carbonate ion and sulfuric acid ion in soil soluble salt and different irrigation and water quality.(3)comprehensive test research.From the perspective of water quality and water quantity ratio of irrigation,the integrated risk of irrigation with water of 1.1l is the lowest.Mixed water 1.1l of irrigation water can be used for irrigation.
