Technical Key Points:

(1) Utilise the anaerobic hydrolysis and acidification stage to alter molecular structures, thereby creating favourable conditions for aerobic treatment.

(2) Sludge recirculation maintains high sludge concentration, whilst the anaerobic tank is utilised to digest the sludge.

(3) Hydraulic pulsed distribution is employed for influent to the anaerobic tank, and a three-phase separator is used for effluent to enhance treatment efficiency.

(4) Fibre-based media is installed within the anaerobic and aerobic tanks to maintain high sludge concentration.

Technical Features:

(1) Treatment performance is stable and reliable, with good resistance to shock loads; significant removal of CODcr and colour is achieved.

(2) Anaerobic treatment is carried out at ambient temperature, requiring no heating; this results in low energy consumption, convenient management and reduced treatment costs.

(3) The volume of surplus sludge is small, environmental conditions are favourable, the equipment footprint is compact and capital investment is low.

Anaerobic-Aerobic Starch Wastewater Treatment with Biogas Recovery

Anaerobic-Aerobic Starch Wastewater Treatment with Biogas Recovery Product Details Technical Highlights: This process employs an anaerobic-aerobic biological treatment method for high-concentration organic wastewater. The anaerobic treatment unit utilises the UASB (Upflow Anaerobic Sludge Blanket) process, whilst the aerobic treatment employs the SBR (Sequencing Batch Reactor) process. Following anaerobic treatment, the refractory CODCr in the wastewater…
