摘要
SBR法的工艺流程简单,且造价低,主体设备只有序批式间歇反应器,无二沉池与污泥回流系统,初沉池也可省略,布置紧凑,占地面积小,可根据水质和水量情况灵活运行,具有良好的脱氮除磷效果。采用SBR法处理农村生活污水,COD,BOD,SS,TNP和NH3-N去除率高,并且都能达到GB8978-1996中一级排放标准。
Simple technological process and cost of construction are the features of SBR. Sequencing batch reactor is its main equipment, the equipment of return sludge and primary settling tank is omitted, It has a compact structure and flexibility of operation base on the basis of the amount of sewage quality. The removal efficiency of nitrogen and phosphorus is very good. So we use SBR to treat the domestic sewage. The result showed that high quality of effluent could be obtained by the means of SBR, and the removal efficiency of COD, BOD, SS, TNP and NH3-N were very high. The effluent water quality meets GB8978-1996 I standard.
