Embodiment 1

[0037] see Figure 1-Figure 3 As shown, this embodiment provides a construction method for in-situ solidification of sludge, including:

[0038] Step 100: Use in-situ solidification equipment to solidify the sludge in the shallower area 2 in the sludge pit 1, so that the area forms a solidified area 3, and the remaining area in the sludge pit 1 is an uncured area 4 ;

[0039] Step 200, when the sludge strength in the solidified area 3 meets the requirements, set up a turnover pit 5 near the uncured area 4 in the solidified area 3, and the in-situ solidification equipment can control the turnover pit 5 The sludge in the pit 5 is solidified;

[0040] Step 300, transferring the sludge in the unsolidified area 4 to the turnover pit 5, and using the in-situ solidification equipment to solidify the sludge in the turnover pit 5;

[0041] Step 400, after the solidification treatment of the sludge in the turnover pit 5 meets the requirements, transfer the sludge in the turnover pit ...

Abstract

The invention relates to the technical field of sludge treatment methods, in particular to a sludge in-situ solidification construction method. The sludge in-situ solidification construction method includes: step 100, using in-situ solidification equipment to solidify the sludge in the shallower area of ​​the sludge pit; Set up a turnover pit near the uncured area; step 300, transfer the sludge in the uncured area to the turnover pit, and use in-situ curing equipment to solidify the sludge in the turnover pit; step 400, when the sludge in the turnover pit After the sludge has been solidified to meet the requirements, the sludge in the turnover pit is transferred to the unsolidified area; step 500, step 300 and step 400 are repeated until all the sludge in the sludge pit is solidified. The invention provides a sludge in-situ solidification construction method to solve the technical problem in the prior art that the ultra-deep sludge in the sludge pit is difficult to solidify.

Description

technical field [0001] The invention relates to the technical field of sludge treatment methods, in particular to a sludge in-situ solidification construction method. Background technique [0002] Due to the long-term neglect of the sludge disposal problem generated by sewage treatment plants, the sludge produced by most sewage treatment plants in China has not been effectively treated and disposed of. The sludge of sewage treatment plants refers to the solid, semi Solid and liquid wastes contain a large amount of organic matter, heavy metals, pathogenic bacteria and pathogenic bacteria, etc. [0003] Among them, most of the sludge is dumped randomly or enters domestic waste landfills in violation of regulations, resulting in a large number of sludge pits all over the country. After the sludge enters the sludge pit, if it is not treated, it will basically maintain its original state after a few years. It will cause serious secondary pollution to the environment. As the cou...
