preparation example

[0041] The preparation of sludge modifier is as follows:

[0042] Mix river sand, coconut peat, branch particles, volcanic rock filter material and deodorant uniformly according to the formula ratio to prepare the silt modifier. Wherein, by volume ratio, the silt particles: river sand: coconut bran: branch particles: volcanic stone filter material: deodorant=(3-8):(2-5):(1-3):(1- 3):(1-2):(1-3). The deodorant is selected from traditional Chinese medicine dregs or tea dregs.

preparation example 1

[0044] The total volume of the silt conditioner is 1m 3 , by volume ratio, river sand: coconut peat: branch particles: volcanic rock filter material: traditional Chinese medicine slag=6:5:4:3:1.

preparation example 2

[0046] The total volume of the silt conditioner is 1m 3 , by volume ratio, river sand: coconut peat: branch particles: volcanic rock filter material: traditional Chinese medicine residue = 2:1:1:1:1.

Abstract

The invention relates to the technical field of sludge treatment, and particularly discloses an in-site sludge improvement method and a sludge planting soil. The in-situ sludge improvement method comprises the following steps: S1, dewatering dredged sludge to enable the water content of the dewatered sludge to be less than or equal to 60%, and crushing the dewatered sludge into sludge particles; S2, uniformly mixing the sludge particles with a sludge modifier to obtain the sludge planting soil, wherein the sludge modifier comprises river sand, coco coir, branch particles, a pelelith filter material and a deodorant; and S3, using the sludge planting soil for landscape greening in site. The sludge in rivers and lakes is improved in situ, so that rapid treatment and reutilization of the sludge are realized, maximized and efficient reutilization of resources is realized, and the method has remarkable social benefits, environmental benefits and economic benefits.

Description

technical field [0001] The present application relates to the technical field of sludge treatment, and more specifically, it relates to a sludge improvement method and sludge planting soil. Background technique [0002] The sediment of lakes or rivers in cities is affected by residents' activities and has complex components, including microorganisms, pathogens, heavy metals and organic pollutants. It needs to be cleaned regularly, otherwise it will stink and affect people's living environment. Moreover, with the improvement of people's living standards, people's requirements for the living environment are getting higher and higher. At present, many cities in China are dredging around rivers or lakes to improve the water environment. However, limited by the city's environment, these dredging projects usually use dredging ships to dredge the silt, and then use pipelines to transport the dredged silt to specified areas for stacking or natural sedimentation and drying. The exis...
