The influence of anoxia design and change aerations time on the treatment from coke plant wastewater

摘要

According to a great deal of experimental findings and theoretical analysis, the performance of SBR process treating organic substance and ammonia was presented for different operating pattern and aeration time. When the operation mode is feeding water, anoxie mixing 2.5 h, settlement, and draining for 1.5 h, the coke plant wastewater can be treated well by the SBR method.
