Description

Technical Field

[0001] The present invention relates to the field of sludge treatment, and in particular to a sludge in-situ oxidation conditioning device and a use method thereof. Background Art

[0002] With the rapid development of my country's social economy and urbanization, the municipal sewage treatment rate has increased year by year, and the output of municipal sludge, a by-product of sewage treatment, has also increased dramatically.

[0003] In view of the large number of existing non-standard sludge landfill management projects, whether on-site treatment (vacuum or pre-loading drainage) or ex situ disposal (pumping the sludge into plate and frame filter presses, centrifuges, belt filter presses and other dehydration and drying equipment for extrusion dehydration), it is necessary to pre-condition the sludge in the landfill with in-situ chemical oxidation to promote the release of sludge moisture, that is, by injecting strong oxidizing agents into the landfill sludge, the microbial cell walls and organic matter are oxidized and decomposed, and the moisture in the sludge is easily discharged under pressure. However, a problem currently faced by rapid in-situ oxidation conditioning is that when strong oxidants such as Fenton's reagent or hydrogen peroxide are used to condition sludge, a violent oxidation reaction will occur, producing a large amount of toxic and smelly gases such as NH3, CO and H2S. As a result, the construction of in-situ sludge oxidation conditioning is extremely difficult, which greatly hinders the smooth implementation of sludge yard management projects. In addition, when oxidizing sludge, it is easy for the equipment to be difficult to penetrate due to the large and thick sludge area. If pressure equipment is used to apply pressure, it needs to be re-debugged. If multiple devices are used to treat multiple sludge locations at the same time, the pressure equipment is difficult to move quickly, and the configuration of multiple devices will increase losses. At the same time, there is no better and more convenient way to clean the equipment after the sludge is treated.
