Experimental Study on Mechanical Vapor Compression Treatment of Landfill Leachate

Abstract

. This essay dealt with the treatment of landfill leachate by means of mechanical vapor compression. The influence of different feed rate, feed temperature and scraper speed was studied on the heat transfer coefficient of wiped film evaporator. The experimental results showed that the larger the feed rate, the smaller the heat transfer coefficient. The feed temperature and the scraper speed had the optimal value. At this time, the heat transfer coefficient reached the maximum value.
