At present, there is a lack of necessary technical parameters for sludge vacuum reinforcement. To explore the effects of the drain board type on sludge vacuum reinforcement, the Fenton reagent was used to pretreat the landfill sludge in a sludge landfill area in Shanghai, and then, vacuum preloading contrast tests of different prefabricated vertical drainage types were carried out. During the test, the discharge and settlement of sludge were recorded. After the test, the moisture content, shear strength, and appearance of PVD were measured and analysed. The main conclusions are as follows: (1) the optimum ratio of H₂O₂ and Fe²⁺ is 2 for the landfill sludge; (2) the total displacement and accumulated settlement of the test group with integral prefabricated vertical drainage are 1.7 times and 1.2 times those of the separate prefabricated vertical drainage, respectively; (3) the type of prefabricated vertical drainage has no effect on the distribution of water content and shear strength; and (4) when the sludge is vacuum strengthened, the integral prefabricated vertical drainage should be preferred.

Fenton试剂真空预压处理垃圾填埋污泥影响因素的试验研究

目前缺乏污泥真空强化所需的技术参数。为探讨排水板类型对污泥真空强化的影响，采用芬顿试剂对上海某污泥填埋区的垃圾进行预处理，然后进行了不同预制垂直排水类型的真空预压对比试验。在试验过程中，记录了污泥的排放和沉降。试验结束后，对PVD的含水量、剪切强度和外观进行了测量和分析。主要结论如下： (1) H ₂ O ₂与Fe ²⁺的最佳配比填埋污泥为2；(2)整体预制竖向排水试验组的总位移和累积沉降分别为单独预制竖向排水的1.7倍和1.2倍；(3)预制垂直排水的类型对含水量和抗剪强度的分布没有影响；(4)污泥真空强化时，宜采用整体预制垂直排水。
