AIR SUSPENSION BY ADDING SOLUBLE AIR CHEMICAL +A/O BIO- CHEMICAL TREATMENT APPLIED FOR SLAUGHTERHOUSE WASTEWATER ENGINEERING

摘要

Presented in this Article is the design, efficiency and operation management experience obtained from the adoption of the process of "air suspension by adding soluble air chemical + A/O bio-chemical internal circulation" for slaughterhouse wastewater treatment. Advanced and highly effective total mass air suspension reactor is utilized in the engineering. This process has the advantage of low chemical consumption, low energy consumption and small land space occupation. It is shown in the practice that less than l00mg/l CODcr contained in outflow with the removal rate above 96 % under the condition of 2 450mg/l CODcr contained in inflow.
