Service project of emergency treatment of leachate in Zigong City

The Lianhua Refuse Treatment and Landfill Plant is located in Yantan District of Zigong City. It was built in 1995 and covers an area of 150mu with a total storage capacity of 1,846,200 m³. It was closed in 2015. As the original leachate treatment device has poor capacity and low recycling rate, a large amount of leachate is accumulated with a risk of overflow.

Operation time: October 2018

Treatment scale: 600m³/d

Treatment process: Two-stage DTRO

Effluent standard: Meet the standards in Table 3 of the Standard for Pollution Control on the Landfill Site of Municipal Solid Waste (GB16889-2008)
