Abstract: The overall technical routes of “landfill rapid stabilization＋cleaning and excavation＋waste screening＋terminal classification and disposal” combined with “outbound transportation resource utilization” were adopt to carry out the waste treatment and disposal work. The rapid stabilization equipment was operated for two months, and the methane gas concentration ranged from 0.01% to 20.44% to below 3%. Reducing the moisture content of screened waste could improve the screening efficiency, and when the moisture content was lower than 13%, the efficiency was fourteen percentage points higher than the moisture content of about 30%. The leachate that was treated with NaClO, PAC and PAM met the discharge standards. In the process of resource conversion of humus soil, the blending ratio of 40% humus soil could meet the requirement of MU10 strength grade of GB/T 5101—2003 Fired Common Brick. The scale of the waste treatment project was about 180 000 square meters and the total investment was about 135 million yuan. Increasing the air-drying area of waste could provide more low moisture content waste, thus improving the efficiency and volume of waste screening. Because of the uneven distribution of the waste, the rapid stabilization time needs to be longer than the theoretical calculation time.

Key words: informal landfill, rapid stabilization, screening efficiency, humus reclamation
