The invention discloses a preparation method of novel environment-friendly solidified soil containing sludge. The preparation method comprises the following steps: preparing a curing agent, pretreating the sludge, solidifying material slurry and forming the solidified soil. The solidified soil is prepared from the sludge, the problems of high manufacturing cost, long period, resource waste and possible secondary pollution of a traditional sludge treatment method are effectively solved, multiple water absorbents are adopted for solidifying the sludge, the requirement can be met without using drying equipment, the water content of the solidified sludge is low, and compared with a traditional solidifying agent, the solidified soil has the advantages that the cost is low, and the cost is low. The first curing agent and the second curing agent can reduce the dead weight of the soil body and the time required for curing, the cured soil body is not prone to caking and can be directly utilized, and waste of resources is prevented.
本发明公开了一种含污泥的新型环保固化土的制备方法，包括以下步骤：制备固化剂、污泥预处理、固化物料浆液和固化土成型。本发明通过污泥制备固化土，有效地解决了传统污泥处理方法造价高、周期长、资源浪费和可能二次污染的问题，而且采用多种吸水剂进行污泥的固化，不使用干化设备即可达到要求，使得固化后的污泥含水量较低，同时与传统的固化剂相比，第一固化剂和第二固化剂能够降低土体自重以及固化所需的时间，固化后的土体不易结块，能够直接进行利用，防止出现资源的浪费。
