将污水污泥和元素硫以不同的比率混合， 为了控制混合物的ｐ Ｈ， 分别加入石灰（ Ｌｉｍ ｅ） 和磷矿石 （ｒｅｃｋ－ Ｐｈｏｓｐｈａｔｅ）。在一定的温度 （３０℃） 和湿度 （９０％ ） 条件下进行培养， 经过９ 周的培养证明， 混合物中污水污泥的含量增加， 元素硫的氧化率增加； 碱性环境有利于混合物中元素硫的氧化； 磷矿石对提高混合物中元素硫的氧化率无效。石灰能促进元素硫的氧化， 加入石灰使元素硫的氧化率从０９８％ 增加到３１１３％ 。从而提高混合物做为一种硫肥的肥料价值。
Sewage sludge and elemental sulfur were mixed at different ratios. To control the p H of the mixture, separately add Lim e and reck-phosphate. After a certain temperature (30 ℃) and humidity (90%) under the conditions of culture, after 9 weeks of culture showed that the mixture of sewage sludge increased, the elemental sulfur oxidation rate increased; alkaline environment is conducive to the mixture of elements Sulfur oxidation; phosphate rock to improve the mixture of elemental sulfur oxidation rate is invalid. Lime can promote the oxidation of elemental sulfur, and the addition of lime increases the elemental sulfur oxidation rate from 098% to 3113%. Thus increasing the compound’s fertilizer value as a sulfur fertilizer.
