摘要

在为联合国人类住区中心(人居中心)进行“卡拉奇垃圾回收过程”研究期间,对可回收材料的主要组成部分有机腐烂物质进行了化学评价。分选后的平均腐坏物质pH值为6.1;水分39·5%;有机质56%;碳34%;氮1·2%;C/N 28。这些数字符合好氧堆肥所需的最佳值,因此这部分垃圾是进行生物转化的合适材料。

Chemical composition of putrescible vegetable matter in municipal waste from Karachi—a case study

During studies on ‘Refuse Recycling Processes in Karachi’ for the United Nations Centre for Human Settlement (UNCHS-Habitat), a chemical evaluation of organic putrescible matter, a major component of recyclable materials, was carried out. The average putrescible matter (after sorting) had pH 6·1; moisture 39·5%; organic matter 56%; carbon 34%; nitrogen 1·2%; and C/N 28. These figures are in conformity with the optimum values needed for aerobic composting and hence this portion of refuse is a suitable material for bioconversion.
