对比研究了单独微波和柠檬酸-微波联合处理对污泥破解的影响。以微波辐射时间和微波功率为控制参数，研究了不同条件下污泥有机物溶出的情况和污泥沉降性能的变化。研究结果表明，在微波功率为616 W、辐射时间为150 s、投加0.05 g/g·SS柠檬酸处理污泥时，样品的溶出率为24.66%，对比单独微波法作用，污泥有机物溶出明显增加；使用柠檬酸-微波联合破解污泥，可使污泥SV₃₀降至21.22%，SVI降至27.99 mL/g，较单独微波法效果显著，可有效改善污泥沉降性能。

The effects of microwave alone and citric acid-microwave combining treatments on sludge disintegration are compared and studied.Taking microwave irradiation time and microwave power as control parameters,the dissolution of sludge organic matters and the change of sludge sedimentation performance under different conditions are studied.The research shows that the dissolution rate of organic matters can achieve 24.66% when the microwave power is 616 W,the irradiation time is 150 s,and 0.05 g·g^-1·SS citric acid is added to treat the sludge.Compared with the microwave-alone method,the citric acid-microwave combining method can gain a significant higher dissolution of sludge organic matters.Using citric acid-microwave to disintegrate sludge,sludge SV₃₀ can reduce to 21.22% and SVI can drop to 27.99 mL·g^-1,which is more effective than using the microwave-alone method and can improve effectively the sludge settling performance.
