摘要
随着经济的快速发展和大量固体废物的出现 ,垃圾填埋成为目前垃圾处置的主要趋势 ,渗滤液的处理也至关重要。渗滤液处理的效率受pH值的影响 ,由于渗滤液量与成分随着季节不同不断发生变化 ,且pH值控制由于其严重的非线性和滞后性使控制相当困难。运用各种算法的计算机控制为渗滤液pH值控制提供了一种有效的途径 ,本文有机结合了反馈与前馈控制的优点 ,设计了一个可控性的pH值处理工艺流程。
With the emergence of the large amount of solid waste,sanitary landfill has been now a main tendency,and leachate treatment is indispensable.The effectiveness of treatment is related to pH value.the quantity and compositions of the leachate change continuously with different seasons.so it is very difficult to control pH because of the nonlinear characteristics and deadtime.Computer control can offer an effective way to control pH of the leachate.A controllable treatment process is designed by combining feed forward with feedback.
