摘要：结合西部高原高寒地区的区域条件,以堆肥温度和发芽指数为指标,研究常规调理剂、微生物菌剂以及微生物菌剂与常规调理剂组合对当地污泥堆肥的适应性。结果表明:锯末、干草、羊粪、鸡粪和餐余垃圾能够满足当地污泥堆肥需要,与空白污泥相比,堆肥温度至少可以提高9.8℃,发芽指数至少可以提高23.64%;添加微生物菌剂可使污泥堆肥温度提高1.7℃,发芽指数提高17.19%;组合使用可使堆肥温度提高11℃,发芽指数提高25.17%。因地制宜,筛选出可行调理剂:微生物菌剂+餐余垃圾+鸡粪。
Based on the regional conditions of the alpine region of the western plateau, the compost temperature and germination index are used as indicators to research the adaptability of conventional improvers, microbial inoculants, or combinations of microbial inoculants and conventional improvers to local sludge composting. The results show that sawdust, hay, sheep manure, chicken manure and meal waste can meet the local sludge composting needs. Compared with pure sludge, the compost temperature has increased by9.8 ℃, and the germination index has increased by 23.64%;the addition of microbial agents can increase the compost temperature by1.7 ℃ and the germination index by 17.19%;the combination of microbial inoculants and conventional improvers can increase the compost temperature by 11 ℃ and the germination index by 25.17% respectively. According to local conditions, a feasible conditioner is selected: microbial inoculum + meal waste + chicken manure.
