Joint sewage treatment plant unit includes pre-treatment facilities (Trash channels, collection wells, desilting equipment, and mixthoroughly pool), chemical aggregation equipment (pH adjusted pool, rapid mixing tank), the middle of biological treatment systems(anaerobic reactor, powder Like activated carbon biological treatment tank, settlement tank), after the section of tertiary treatment,discharge pool.
Leachate treatment of waste sanitary landfills for the township units 1, 19-line and 17-lane highway near the town,like Jiali Township, Sigang Township, Madou Township, Shanhua Township, Sinhua Township, Guanmiao Township, Gueiren Township, RendeTownship etc.Township of waste sanitary landfill, expected to seepage of water, 477 CMD (per ton of garbage leachate generated 1CMD dollars, the estimated total seepage, 837 CMD) However, considering the township offices of waste sanitary landfill seepage watertreatment, foldback, closure and other factors, the average daily design sewage treatment is about 600CMD, Design water quality pH=6~9、COD=6,000 mg/l、SS=600 mg/l、BOD5=1,300 mg/l、NH3-N=600 mg/l，by 90 years on November 21 to announce CentralDepartment of Water announced ○○六九九七 orders to announce of the rules of the standard of the liquid waste fluid matte, pH=6~9、COD=200 mg/l、SS=50 mg/l.
Leachate Treatment Process
System Units:
Pre-treatment System → Chemical Treatment System → Biological Treatment System → Tertiary Treatment System → Sludge Treatment System
Equipment Units:
Bar Screen Channel → Collection Well → Sand Washer → Equalization Tank → pH Adjustment Tank → Rapid Mixing Tank → Flocculation Tank → Primary Sedimentation Tank → First-Stage Anaerobic Tank → First-Stage Aerobic Tank → Intermediate Tank (I) → Sedimentation Tank (I) → Second-Stage Anaerobic Tank → Second-Stage Aerobic Tank → Sedimentation Tank (II) → Intermediate Tank (II) → Automatic Filtration & Recovery System → Return Sludge Distribution Tank / Effluent Discharge Tank
- Primary Sedimentation Branch Line
Primary Sedimentation Tank → Sedimentation Tank (I) / Chemical Sludge Thickening Tank & Biological Sludge Thickening Tank
First-Stage Anaerobic Tank ← Sedimentation Tank (II) → Return Sludge Distribution Tank
- Activated Carbon Addition Line
Activated Carbon Dosing System → Return Sludge Distribution Tank → Second-Stage Anaerobic Tank → Second-Stage Aerobic Tank → Sedimentation Tank (II) → Intermediate Tank (II) → Automatic Filtration & Recovery System → Return Sludge Distribution Tank / Effluent Discharge Tank
