添加物对填埋场稳定化时间的影响

EFFECT OF CHEMICALS AND SLUDGE ON THE STABILIZING TIME OF REFUSE LANDFILL

在垃圾中添加ＫＣｌ、ＫＨ_２ＰＯ_４、（ＮＨ_４）_２ＣＯ_３、ＦｅＣｌ_２时，对垃圾降解和填埋场稳定化时间的缩短有促进作用，而ＣｕＳＯ_４、Ｋ_２Ｃｒ_２Ｏ_７、Ｎａ_２ＭｏＯ_４、Ｎａ_２ＷＯ_４、醋酸的加入则抑制了垃圾的降解，认为ＫＣｌ是促进垃圾降解，加速填埋场稳定化的最佳添加物。

Effect of the addition of various chemicals,such as KCl and sludge,into the municipal refuse on the degradation and stabilization of landfill was investigated initially. It was found that the addition of KCl,KHPO_4,(NH_4)_2CO_3,and FeCl_2,can shorten the stabilizing time of landfill,while that of K_2Cr_2O_7,Na_2WO_4,Na_2MoO_4,CuSO_4 and acetic acid was unfavorable to the stabilization of landfill.It was considered that the addition of KCl was the optimum alternative for the accelerating stabilization of landfill.
