Effects Of Cellulosic Ethanol Anaerobic Wastewater On The Growth Of Wheat And Soil Improvement

Cellulosic ethanol,one of the clean energy,has become an important point in the development of circular economy.In the process of cellulosic ethanol production,a large number of biogas slurry was produced,and the "zero discharge" and effective applications have become quite important.In recent years,with the intensification of the global shortage of resources,environmental pollution and ecological destruction and other issues,the agricultural land fertility is becoming serious.Based on the industrialization development of cellulosic ethanol,a comprehensive study on the irrigation soil with cellulosic ethanol anaerobic biogas slurry,the growth characteristics of post-irrigated crops,crop quality,soil and ecological environment were performed,combined with laboratory and field tests.Main results are as follows.1.After infiltrating with cellulosic ethanol anaerobic biogas slurry,the budding rate of wheat seed was slightly lower than that of the control group.There was not significant change in corn seed.The total length,diameter,volume,dry weight and other characteristics of post-irrigated wheat root were better than that of the control group.2.After irrigation with cellulosic ethanol biogas slurry,wheat tillering was promoted,the plant height was increased,and the stem is hairchested.In addition,the"ear" number of wheat has increased significantly.The yield increased about 7%,and there were no effects on the quality of wheat.3.After irrigation,there were no major changes in the main physical indicators compared to basic soil.In addition,the organic matter and the total nitrogen increased to some extent,and other main chemical indicators showed no significant change.4.After irrigation with cellulosic ethanol anaerobic biogas slurry,various indicators of groundwater were unchanged during the testperiod of one year field experiment.5.The ecosystem has a strong treatment power on main pollutants of cellulosic ethanol anaerobic biogas slurry.The results demonstrated that irrigation with cellulosic ethanol production wastewater would be feasibility,which will reduce the cellulosic ethanol production cost,achieve a virtuous circle of ecological environment,desirable good economic,environmental and social benefits.
