摘　　要：在中试条件下考察了新型高压板框式脱水机对污泥的脱水性能。结果表明：在污泥初始含水率为98．7％的条件下，与普通板框式污泥脱水机相比，经二次高压脱水后的泥饼含水率能够降低5％以上；当聚合氯化铝（PAC）和阳离子聚丙烯酰胺（PAM）的投配率分别为（3．5％－4％）和0．09％时，泥饼含水率能够达到60％～65％，与单独投加PAC相比，泥饼含水率可下降5％－7％，同时可节约15％～20％的药剂成本。The sludge dewatering performance of novel high pressure plate and frame dehydrator was investigated. The results showed that for the sludge with moisture content of 9g. 7% , the moisture content of sludge cake after the secondary high pressure dehydration could be reduced by at least 5% , compared with the sludge cake without secondary high pressure dehydration. Under the condition of PAC and PAM dosing rates of 3.5% to 4% and 0.09% respectively, the moisture content of sludge cake with the secondary high pressure dehydration could range from 60% to 65% and declined by 5% to 7% with chemical cost savings of 15% to 20% compared with adding PAC alone.
