Zhongshan City south group comprehensive waste treatment base organic waste resource treatment project sewage treatment system
Wastewater type：
kitchen waste biogas slurry, low concentration wastewater, deodorizing circulating water
Processing scale：
Kitchen waste biogas slurry: 1000 m³/d; Low concentration wastewater: 250 m³/d; Deodorizing circulating water: 300 m³/d
The process of high concentration sewage is：
"regulation tank + two-stage biochemical + ultrafiltration (external MBR) + nanofiltration", and the concentrated liquid is: "reduction + two-stage Fenton + three-stage AO+ sedimentation tank" full quantization process
Low concentration sewage using the process: "grease trap + regulating pool + coagulation sedimentation + intermediate pool +A2/O+ membrane pool" treatment process
Deodorizing circulating water adopts the process of：
"grease trap + regulating pool + hydrolytic acidification + contact oxidation + secondary sedimentation tank" treatment process
Effluent standard: "Quality Standard of Sewage discharged into Urban Sewers" (GB/T31962-2015) Grade B
Scale dam landfill leachate treatment and upgrading project
Wastewater type：
landfill leachate, concentrated liquid
Processing scale：
2000 m³/d
Adopted process：
"pretreatment (recycling) +DTRO (recycling) + equalization tank + external MBR+ primary NF+ Secondary NF+ electrocatalytic oxidation", in which nanofiltration concentrate adopts full quantization process: "nanofiltration concentrate reduction + high-efficiency coagulation precipitation + two-stage Fenton oxidation + deep biochemistry"
Effluent standard：
Table 3 standard of Domestic Waste Landfill Pollution Control Standard (GB16889-2008)
Xi 'an Aerospace Base transfer station project
Type of wastewater：
leachate from refuse transfer station
Processing scale：
80 t/d
Process：
pretreatment + regulating tank + equalization tank + high-load biochemical reactor (two-stage biochemical) + external ultrafiltration +NF membrane treatment system and nanofiltration concentrate reduction system
Implementation standards：
"Comprehensive sewage discharge Standard" (GB8978-1996) in the third standard and "sewage discharge into the urban sewer water quality standard" (GB/T31962-2015) in the B standard
Guangzhou seventh resources thermal power plant phase II project and supporting facilities leachate treatment station project
Wastewater type：
leachate from incineration plant and low concentration production wastewater
Treatment scale：
900 m³/d (including 720 m³/d of leachate from incineration plant and 180 m³/d of low-concentration production wastewater)
Adopted process：
"pretreatment + anaerobic + external MBR (two-stage A/O) +NF+RO", wherein NF concentrated liquid adopts two-stage material film treatment process, RO concentrated liquid adopts chemical dehardening + tubular softening film + high-pressure film treatment process
Implementation standard：
Supplementary water standard of open circulating cooling water system in "Quality of Industrial Water for Municipal Sewage Recycling" (GB/T19923-2005)
