Application of UASB Reactor in Leachate Treatment of Beijing Asuwei Waste Sanitary Landfill Site

The UASB reactor was used to reconstruct leachate treatment project of Beijing Asuwei Waste Sanitary Landfill Site,and the commissioning with the UASB reactor was executed.Water quality indicators were determined in the debugging process,and the results showed that the VFA content in the anaerobic tank was controlled within 600 mg/L,which indicated that the water quality did not have the acidified phenomenon.The COD removal efficiency was 50%approximately and NH_3-N concentration showed as light decline when operation stability in anaerobic system.

大尺寸拖马产品的力学实验装置设计研究

近年来,滚装船、特种货物运输船、散货船、支线船、内河船的订单呈上升趋势,对大尺寸绑扎产品的压力强度要求高。但是,市场上现有的实验设备不能满足大尺寸的产品压力实验要求。针对大尺寸的滚装船用绑扎件产品拖马的压力实验特点,本文设计一种非标的压力实验装置,采用四柱框架式结构,通过静力学的数值模拟和实验验证该装置的变形量。最终,实验结果表明该结构实验时变形小,可应用于滚装船用绑扎件产品的力学实验测试,也为其它类似大尺寸产品的压力实验,提供了工程上的解决方法和手段。
