摘要
Abstract
Through the practice of intermediate-water reuse works in the BAF( biological aerated filter) for debugging, its optimum operating condition parameters were abtained for wastewater treatment,and reuse university has a certain meaning and value with engineering design and actual production run. The paper debugging analyzed the BAF in reclaimed water station of Changqing campus of Shandong Normal University. Changing BAF aeration by controlling the flow valve and pressure relief valve on the water pipe aeration pipes to study impact of gas-water ratio on the processing performance of BAF. In capacity of BAF remains unchanged,change its water flow,thus changing the HRT to study impact of HRT( Hydraulic retention time)on the processing performance of BAF. The results show that is whar BAF gas-water ratio of 4. 0 to 5. 5:1 range,CODcr( Chemical oxygen dimand)removal rate is 86. 7% ~90. 1%,and SS(Suspended solid)removal efficiency of up to 48 . 4% ~64 . 8% under the conditions of temperature of 23~29 ℃. When HRT is 3 . 0 ~ 4 . 0 h range,CODcr removal rate is 85. 8% ~91. 3%,and the removal efficiency of SS is up to 54. 0% ~57 . 7 under the conditions of temperature of 23~29 ℃.关键词
