摘要
目前昆明市处理城市污水３６５ 万ｍ ３／ｄ ， 同时产生污泥１３０ｔ／ｄ ， 至２０００ 年， 污泥的数量还会增加至２２０ｔ／ｄ 左右， 如处置不当， 极易造成二次污染。通过污泥成分分析，发现污泥中含有植物生长所需的大量营养元素， 可用于花卉园林栽培， 既满足了日益发展的园林产业的需要， 又为污泥的消纳和利用找到一条合理的途径。
At present ,365 thousand M 3/d sewage water in kunming City is handled and 130t/d sludge is produced .The sewage sludge may increase to about 220t/d. If improperly treated, the second pollution will be resulted. Through analysis of sewage sludge components, the author finds that large amount of nutrient elements ennded by growing plants are contained which can be used in horticulture and gardening so as to fulfill the need of these two increasingly developing industries and find an outlet for the sewage sludge.
