Multiple landfill cells lined with HDPE
membrane for leachate containment;
Comprehensive leachate collection and
conveyance system;
Landfill gas collection system;
A 500m3 per day advanced leachate
treatment plant with a membrane bioreactor and advanced nano-filtration
system to meet the highest effluent
discharge standards in China (COD:
40ppm, BOD:10ppm);
A 60,000 m3 leachate balance pond with
floating HDPE membrane cover;
Full Scada and online monitoring system
and smart-tag weighbridge system;
Administration office, workshop and staff
quarters;
Internal roads and surface runoff system;
Guardhouse and perimeter fences; and
Embankments, slope revetment and
emergency protection system.
Presently, the Sanshui Landfill disposes 500
tonnes per day of waste and is designed to cater
for 1,200 tonnes per day of waste in the future.
Generation of leachate is minimized by temporary
HDPE cover liner and separation system of surface
runoff at the landfill cell.
This Landfill Project received several awards
from the Government at provincial and national
levels: ●●
“National 1 st Class Sanitary Landfill” by
China Association of Urban Environmental
Sanitation in September 2013.
●●
“1 st Class Sanitary Landfill” in Urban
Environmental and Sanitation of
Guandong Province by Guangdong
Provincial Government in July 2012;
●●
Guangdong Provincial Award for
Outstanding & Advanced Corporation
from the Guangdong Business Council
and Entrepreneur Association in July
2012.
Leachate collected in the Landfill Cell is stored at leachate balancing pond for anaerobic treatment
process and followed by secondary and tertiary treatment in the advanced leachate treatment plant.
Membrane Bio-reactor and nano-filtration system was adopted in the Leachate Treatment Plant to
meet the highest effluent discharge standard in China.
