Machine matter and other hard-degraded substances, thus reach the purpose of sediment in-situ minimizing.
B, the bed mud after biology in situ decrement is carried out in-situ solidifying process:
1. when, after biology in situ decrement, when bed mud thickness meets flood passage condition, directly adding in bed mud at the bottom of the S type of my company
Mud firming agent, carries out in-situ solidifying process to bed mud in riverbed.
2. when after biology in situ decrement, during the basic function such as bed mud thickness effect flood passage, shipping, to excess thickness bed mud
Carry out dredging, excavating.
The solidification fill of C, sloping bank or plantation: adding E type or S type firming agent in the bed mud of excavation, the height improving bed mud contains
Water rate and low-intensity, carry out in-situ solidifying to bed mud；Bed mud after solidification is used for fill or ploughing as bank, river course vegetation
Plant soil use.
As the further scheme of the present invention: arrange cofferdam by river course temporary subsection.
As the further scheme of the present invention: microbial bacterial agent uses high-effective microorganism organic matter degradation microbial inoculum (LZB-
1043).
As the further scheme of the present invention: microbial growth promoters uses Black Liquor with Efficient Bacteria growth-promoting agent (LZB-7001).
As the further scheme of the present invention: bed mud curing agent uses S type firming agent, after solidification, bed mud is ploughed as vegetation and is planted
Soil.
As the further scheme of the present invention: bed mud curing agent uses E type firming agent, the bed mud after solidification is used for brickmaking and builds
Dike.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention, compared with existing pollution of river sludge handling mode, has an advantages below:
1, resource: compared with traditional sediment mode, the present invention can make full use of existing waterway and carry out sludge in-situ admittedly
Change fill and shore protection processes.
2, local use, flexible operation: compared with traditional bed mud joint disposal mode, the present invention not by river topography and
The restriction in geographical position, can make full use of existing waterway and carry out bed mud biology minimizing process in situ.
3, comprehensive utilization, non-secondary pollution: compared with traditional bed mud comprehensive treatment mode, the present invention is only carried out in river course
The biology in situ minimizing of bed mud and solidification integrated treatment, be fixedly arranged at heavy metal in cured product simultaneously or be used as quilt during greening
Vegetation absorbs, and eliminates the secondary pollution problem of bed mud.
4, bottom mud microbe and the content of organic matter are high: owing to bed mud uses microorganism decrement treatment in situ, therefore open
Containing abundant microorganism and organic matter in the bed mud dug, afforest as sloping bank, the beneficially growth of vegetation.
