Landfill stock sludge curing agent formula and construction method thereof
The invention provides a landfill stock sludge curing agent formula and a construction method thereof. The landfill stock sludge curing agent formula comprises a conditioning agent, a cured material and a reinforcing agent, the regulator is ferrous sulfate heptahydrate; the condensate comprises cement, calcium oxide powder and fluidized bed combustion ash; the reinforcing agent is polypropylene fiber; the formula is used for being mixed with sludge, so that the sludge added with the curing agent is conveyed into a sludge pit for in-situ curing. The investment is low, the treatment amount is large, and the operation cost is low; the agent adding amount can be accurately controlled, and it is better guaranteed that agent adding is more uniform; the problem of dust raising in the construction process is effectively controlled, the sludge strength and the foundation bearing capacity of the sludge pit after in-situ curing are remarkably improved, the purpose of fully utilizing waste can be achieved by adopting the fluidized bed combustion ash as an auxiliary curing agent, and the purpose of treating waste with waste is achieved; the stirring device can clean the raw materials remaining on the inner wall without forming stockpiling, so that the mixing efficiency is improved, and the device is suitable for popularization and application.
本发明提供一种填埋类存量污泥固化剂配方及其施工方法，包括调节剂、固化物和加强剂；调节剂为七水硫酸亚铁；固化物包括水泥、氧化钙粉和固硫灰；加强剂为聚丙烯纤维；本配方用于与污泥混合，以使添加了固化剂的污泥送至污泥坑内，进行原位固化。具有投资少、处置量大、运行费用低；能够精确的控制药剂添加量，并更好的保证药剂添加更均匀；施工过程中扬尘问题得到有效控制，显著提高原位固化后污泥坑污泥强度及地基承载力，采用固硫灰作为辅助固化剂可达到废物充分利用的目的，以实现"以废治废"；搅拌装置能够清理残留在内壁上的原料，不会形成堆料，提高混合效率，适合推广使用。
