Aerobic sludge compost and its application for eucalyptus fertilization
-
摘要: 研究生活污泥腐熟菌株的生长条件,堆肥接种剂L201在pH 7.7及温度58~65℃时生长较好,堆肥接种剂L301的最适生长温度是52~55℃;仓式好氧堆肥的前期通气量较少,中、后期通气量较多。施用有机肥LC301可以加快桉树生长。Abstract: Growth conditions of rotting bacteria in municipal sludge were studied.The results showed that the microbial inocula L201 grew well under pH 7.7 at 58-65℃,and the optimal growth temperature for the microbial inocula L301 was 52-55℃.Less air ventilation was required during the initial than the other stages of the aerobic compost in an enclosed chamber.Application of the organic fertilizer LC301 promoted eucalyptus growth.The technology developed in this experiment was suitable for sludge treatment of middle and small municipal wastewater treatment facilities or livestock farms.
