Introduction to products
Anaerobic plus aerobic process is adopted to inlet water COD 2500-10000mg/L; the designs of anaerobic reactor and contact oxidation pond are optimized to accelerate culture and domestication of anaerobic and aerobic sludge with the aim of quickly starting reactor and achieving high efficient operation and control. The quality of inlet water complies with Grade Ⅰ and Ⅱ standard listed in table 4 in GB8978－1996 Combined Sewage Discharge Standard. The goal of sterilization and purification can be achieved through eliminating all bacteria and viruses in water.
The equipment features simple and flexible design, stable and reliable operation, small floor area, less investment on infrastructure construction and low operating cost etc.
