摘要

摘要: 以城镇污泥快速稳定化为目的,将污泥与蚯蚓粪以质量比2:1混合作为处理组(WF),以不添加蚯蚓粪的污泥作为对照组(W),在(20±1)℃条件下进行对比试验,试验共进行50 d,研究蚯蚓粪对城镇污泥降解过程的影响。结果表明:与对照组相比,处理组污泥中有机质(OM)浓度降低了4.2%,电导率(EC)提高了79.0%,N $H 4 +$ -N浓度提高了110.0%,N $O 3 -$ -N浓度降低了83.5%;试验过程中,处理组pH变化幅度低于对照组,蚯蚓粪能促进污泥氨化,稳定污泥pH;添加蚯蚓粪使城镇污泥中有机质降解程度更高,矿化速度更快,促使城镇污泥快速稳定。蚯蚓粪可用作加速城镇污泥生物降解的添加剂。

Abstract: In order to accelerate the stabilization process of municipal sludge, the effect of vermicompost on the sludge degradation process was studied. Sludge and vermicompost were mixed with mass ration of 2:1 as the treatment group (WF), and the sludge without vermicompost was used as the control group (W). The comparison tests were conducted at (20±1)℃ for a total of 50 days. The results showed that the concentration of organic matter (OM) in the treatment group with vermicompost (WF) was 4.2% lower, the electrical conductivity (EC) and the content of N $H 4 +$ -N were elevated by 79.0% and 110.0%, respectively, and the content of N $O 3 -$ -N was declined by 83.5%. The varied range of pH value in the treatment group was lower than that in the control group during the whole experimental process. The results showed that vermicompost could promote sludge ammoniation and stabilize the pH value. Moreover, the inoculation of vermicompost could reach the purposes of a higher degree of organic matter decomposition and a faster rate of mineralization, which contributed to the rapid stabilization of municipal sludge. Vermicompost can be used as an additive to accelerate municipal sludge degradation.
