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
