Technical field
The present invention relates to nitrifying sludge separation technology field, specifically a kind of simple in construction, easy to use, desliming effect
The nitrifying sludge muddy water pre-separate device that rate is high, desliming effect is good.
Background technology
It is well known that existing nitrifying sludge handling process is to be discharged nitrification tank mud mixture according to nitrifying sludge concentration
To sludge-tank.Mud is deviate from by deslimer through sludge pump and the mixing of PAM flocculants again, clear liquid flows to supernatant liquid pool, then passes through
Reflux pump is back to nitrification tank, and so as to reach the effect for reducing nitrifying sludge concentration, still, prior art processes have following lack
Point and deficiency：Because nitrification tank sludge concentration general control is in 10%-15% or so, therefore not by thirty years of age of the standing of certain time
The moisture percentage in sewage sludge deviate from is higher, so as to the waste for influenceing desliming effect He causing PAM flocculants；Because nitrifying sludge is placed
A period of time can settle, therefore after nitrifying sludge stands a period of time in sludge-tank, a part of sludge containing gas
Can float, another part can then decline, and centre is formed supernatant layer, so as in the desliming operation sludge pump pump to supernatant layer
When, deslimer will be out of service, and sludge pump is by the direct pump of supernatant layer to supernatant liquid pool, and interval time is longer during this（Existing rank
Or so 2 hours of Duan Yuewei）, directly affect desliming efficiency；Inadequate if left standing for the time, the nitrifying sludge sedimentation in sludge-tank is just
Carrying out, the mixed proportion of PAM flocculants can be being influenceed because sludge concentration is uneven during desliming during this, so as to cause abjection
Moisture percentage in sewage sludge is too high or too low, and the too high influence sanitary landfills of moisture content, moisture content is too low, easily causes deslimer to block.
