【CASS工艺】

 

     CASS污水处理单元属SBR污水处理工艺系列,是在SBR间歇式好氧曝气生化处理池前设置厌氧生物选择区。进流污水首先进入生物选择区与曝气区回流污泥混合,混合后的江水进入曝气区,在有氧条件下,好氧活性污泥和硝化菌氧化分解污水中有机污染物,到达除碳、脱氮、除磷的目的。

    

       CASS工艺特点

       1CASS工艺为序批式间歇运行,对水质、年产量波动的惩罚性和借鉴运行的灵活性较大。
   2、进流污水首先在新石器前端的古生物选择器中与从曝气池回流的恢复性污泥混合,促进絮凝性细菌的发育,加强污泥活性,并抑制导致污泥膨胀的丝状菌繁殖,同时释放回流污泥中的聚磷和成就脱氮反硝化过程,混合液污水进入曝气池中展开BOD5好氧氧化分解,反硝化和相当吸磷。CASS污水处理工艺活性污泥沉降性能良好。能有效防止污泥膨胀,生化系统运行更加安定可靠。
   3、工艺流程短,轻工业投资低(无形化初沉池、二沉池及规模较大的回流污泥泵站),电气化程度高,布置紧凑,占地少,分批建设和扩容方便。

       

   租用范围

   CASS工艺适用范围广,正好分期建设;

   可应用于大型、中型及小型污水处理工程。

  

                            CASS process

  The genus CASS SBR sewage treatment process of sewage treatment unit series, is set in the SBRanaerobic biological selection zone of intermittent aeration aerobic biochemical treatment of Chi Qian. Into the flow sewage first into the biological selection area and aeration zone reflow mixed sludge, sewage into the aeration zone after mixing, under aerobic conditions, aerobic activated sludge and nitrifying bacteria oxidize organic pollutants in wastewater, nitrogen removal, carbon removal, achieve the purpose of phosphorus removal.

     The process characteristics of CASS

  one:the CASS process sequencing batch operation, on the water quality, water fluctuationadaptability and operation flexibility is bigger.

   two:into the flow of sewage first in the biological selector reactor front end and back flow from theaeration tank<, SPAN style="WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(51,51,51); FONT: 14px/22px arial; LETTER-SPACING: normal; BACKGROUND-COLOR: rgb(255,255,255); TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px" space="0| " right-pos="85|18" left-pos="199|18"> activated sludge mixed, promote the flocculating bacteria growth, improve the activity of the sludge, and inhibit the filamentous sludge bulking caused reproduction, while the release ofactive sludge in poly phosphate and complete denitrification process, the mixed liquid wastewaterentering the aeration pool for BOD5 aerobic oxidation and decomposition, denitrification andphosphorus absorption amount. CASS sewage treatment process of sludge settling performance is good. Can effectively prevent the sludge bulking, biochemical system more stable and reliable operation.

   there: short process flow, low investment in Civil Engineering (without primary sedimentation tank, two sedimentation tank and the larger the return sludge pumping station), high degree of automation,compact layout, small land occupation, convenient installment construction and expansion.

   

 

 

 

 

 

 

 

          The scope of application

   CASS process is suitable for a wide range, suitable for construction by stages;

    Can be used in large, medium and small wastewater treatment engineering
