Organic Contamination and Biodegradability of Landfill Leachate
Two different leachates of Chang ˊan landfill in Chendu were collected as the object of study. The components of organic pollutants in leachates were detected by combined GC-MS technique based on the general water quality analysis. Test results of study are as the follows: the type and nature of organic pollutant effect directly on leachate biodegradability. In high biodegradability (BOD5/CODCr=0.3 ～0.4) leachte ,the detected organic pollutant are mainly composed of carboxylic acids and their content accounts for about 90%. While in low biodegradability (BOD5/CODCr ＜0.15) leachte, the detected organic pollutant are mainly composed of alkanes and their content accounts for about 50%. The research provides a new idea and pathway for the treatment and pollution control of leachate from municipal solid waste landfills. The article presents a optimizing principle of integrated physic-chemical and biological treatment technologies in treating mixed leachate.
