The Study Of Utilizing The Output Liquid As Resource

In this article,contraposing the componential characters of city solid waste,the view that collecting solely the biology waste which can be decomposed by anaerobe was put forward.And the biology waste was disposed by the technique of anaerobic zymosis.Then the every production was collected lonely to utilize as resource.Through the experiment, the anaerobic zymosis character of the biology waste,the property and the approach of utilizing as resource for the leachate.(1)For analyzing the anaerobic zymosis character of the biology waste,the anaerobic reaction would be carried through in three constant temperature phases—medial temperature(38℃),high temperature(45℃)and super high temperature.Then in the disparate temperature,the law would be found between the quantity of leachate,CODCr and NH3-N of leachate and reaction times in anaerobic zymosis of biology waste.(2)Use of magnesium ammonium phosphate(MAP)for removing ammonia in the output liquid,the experiment found that when the pH value=9.5,N:Mg=1.3,N:P=1.2, the treatment effect is the best,removal rate can reach 70%.(3)Author regard the output liquid as adding water,coal as raw material to confect waste coal slurry.It was found that the best single-size class with D_100-200:D₂₀₀=3:7,the best coal and water ratio=1.7:1,at this time coal slurry of the concentration value will reach 65.3%,viscosity value reach 915.6 mPa·s,the stability reach the first class,thermal value reach 32124.14kJ/kg,ash reach10.20%.And the best bimodal size class with:D_100-200: D₂₀₀= 3:7,D_200-250:D₂₅₀=5:5,the coal and water ratio=1.7:1,at this time coal slurry of concentration reach 66.74%,the viscosity value reach 1087.4mPa·s,the stability reach the first class,thermal value reach 34747.34 kJ/kg,ash reach 10.36%.
