摘要
污泥堆肥是一种有效的处理城市污水污泥方法,通过堆肥可以使污泥转化成有利于植物生长的有机肥料。本实验以秸秆作为蓬松剂,让污泥和秸秆按一定比例均匀混合后进行堆肥,实验期间,定期对堆体的温度、水分、有机分、pH值及质量进行测量并得出结论:1)秸秆和污泥恰当比例的混合,高温堆肥可以实现;2)在污泥堆肥过程中,不必对堆体的pH值进行调整;3)蓬松剂的含量影响堆肥效果。
Sludge composting is an effective measure of treatment on municipal sewage sludge and it can change sludge into organic fertilization. In this experiment ,we select the straw as the bulking agents and completely mixe sludge and straw to compost. During the experiment we measure the temperature, moisture ,organic content, pH and quality and draw conclusions： 1 ） High temperature composting can be actualized under the condition that sludge and straw are mixed in a right ratio; 2） It is not necessary to adjust the pH during sludge composting; 3 ） The ratio of bulking agents impacts the result of sludge composting.
