Characteristics of leachate from buried trash composed of disassembling imported electrical appliances and municipal refuse
进口废电器拆解残余固体进入生活垃圾填埋场后渗滤液的特性研究

Solid wastes that remain after disassembling imported unusable electrical appliances constitute a serious pollution source of environment. Experiment on simulated acid rain leaching conditions of about 10 years rainfall showed the following results: When wastes were blended buried municipal in the leachate showed an initial marked increase. In the long run, however, the concentration of various pollutants in the collected leachate approached the pure municipal refuse, as that the amount of CODcr, oil, Cu, Pb, Ni and Hg in leachate did not exceed the limit of standard of discharge. Release of main pollutants in the leaching was generally in accord with the equation: C t=C 0t b .
