根据以废治废的原则,提出以镁盐固化污泥和污泥焚烧灰渣作为原生污泥固化剂.结果表明,当镁盐固化污泥与原生污泥混合搅拌的投加比例达16.7％时,经过7 d的养护,原生污泥含水率由80％降至22％左右:以污泥焚烧灰渣作为固化剂,也能够明显改善原生污泥的脱水性能,在投加比例为4.76％～16.7％的条件下,经过3 d和6 d的养护后,含水率分别降至46.53％～41.08％和34.29％～23.92％.%Based on waste control by waste itself, Mg salt-solidified sludge and sludge incineration ash were used as curing agents for raw sludge. The results showed that moisture content of raw sludge could be reduced to 22% from 80% after 7 days' curing, when aiding ratio of Mg salt-solidified sludge into raw sludge was 16. 7%. Sludge incineration ash as curing agent could improve dewatering performance of the raw sludge. Meanwhile, moisture content of the raw sludge can be reduced to 46. 53%~ 41. 08% after 3 days' curing and 34. 29%~23. 92% after 6 days' curing, when aiding ratio of sludge incineration ash into raw sludge was 4. 76%～16. 7%.
