The dirty mire usually needs to carry on to prepare a processing while using to filter or leaving the method machine of heart to dehydrate, then pass toward the hurl in the dirty mire to add various coagulate, make dirty mire grain flocculate , the structure strengthen for the convenience of dehydrating in the machine.Dehydrating dirty mire to contain water rate generally can reach to 80% or so, but want to make the dirty mire contain water rate to decline to much lower level more difficult, have to develop to prepare a processing method otherly.This thesis aims at the existing dirty mire of the development area wastewater treatment factory in Dalian prepares a processing technique-increase the high mark son flocculate (PAM) of foundation up, unite the surface live and PAM usage, the since low PAM uses quantity, raising the dehydration rate of the surplus dirty mire in the meantime.The experiment expresses as a result:Be dehydrating with the vacuum percolation's method, for take the surplus dirty mire lately, after increasing PAC, sugar beet alkali, the dirty mire contained water rate to lower 6% and 1.3% respectively.While using to leave a heart method to dehydrate, for take the surplus dirty mire lately, after increasing 12 alkyls originally the 磺 sour sodium, sugar beet alkali, the dirty mire dehydration rate raised 2.2% and 1.1% respectively;For be disgusted with the oxygen surplus dirty mire, after increasing 12 alkyls originally the 磺 sour sodium, the dehydration rate of dirty mire raised 2.6%;For good oxygen surplus dirty mire, after increasing sugar beet alkali, the dehydration rate of dirty mire raised 6.1%.The surface live's canning raise dirty mire to sink to decline with main reason of dehydrating the function BE, it can make not only dirty mire the protein of the surface, have another sugar etc. the big member material escape from dirty mire grain, and make these materials dissolve more and easily in water, rece dirty mire grain of cleft water, cause the dirty mire sink to decline speed speed, dehydrate the physical volume decrease of dirty mire.
