Description

A kind of original position movable electric dehydration soil engineering bag on the spot

Technical field

The utility model belongs to the reparation of silt sludge and its application technology as the second resource field, and in particular to be a kind of original position just The movable electric dehydration soil engineering bag in ground.

Background technique

From the sixties in last century, countries in the world have just had begun the improvement to polluted-water.However, in outer pollution sources After centainly being controlled, the concentration of various pollutants is still higher in water body, and analysis is the reason is that because a large amount of in silt sludge Caused by nitrogen and phosphorus pollution, organic pollution and heavy metal pollution.

Traditional silt sludge reparation mainly has covering in situ, dystopy dredging, chemical agent reparation and biological prosthetic etc., reaches The purpose that silt sludge is efficiently repaired, but can not utilize and get both with silt sludge portable soilization, while sludge recovery technique of becoming silted up Segmentation carries out, and increases cost of disposal, reduces silt sludge landfill characteristics rate, the utility model combination silt sludge recovery technique Various recovery techniques are combined into one by advantage and disadvantage, make up the deficiency of single recovery technique.

Electro reclamation is a kind of novel green recovery technique, is received more and more attention in recent years, it has investment Less, the advantages that removal efficiency height and short time, especially for the silt sludge of poor permeability, electric repairing technique has good Application prospect.Electric field can not only promote flowing of the target contaminant in silt sludge, can also enhance the transport energy of microorganism Power improves the removal ability of pollutant in silt sludge.The processing for the silt sludge that simple electric repairing technique pollutes multiplicity is also There is certain limitation, while the high-moisture percentage for the sludge that becomes silted up is also the big problem in recovery technique.

Soil engineering bag is a kind of inclusion body of pipe pocket type made of high-intensitive geotextile (raw material such as polypropylene or polyester), It is mainly used for wrapping up sand class soil, forms flexible, shock proof large volume gravity structure, diameter can be varied as desired, most Long length is up to nearly hundred meters.Currently, traditional soil engineering bag is sewed using high-intensitive geotextile, diameter 1.5-5m, By charging sludge, Free water and absorption water in the removings silt sludge such as gravity dehydration and electric dehydration, to realize dehydration volume reduction Purpose is initially used in shore protection embankment engineering, its application field is more and more wide at present.Previous technique is by these processes It separately carries out, and not portable using being combined with silt sludge, this increases the cumbersome process of silt sludge dewatering in a certain range And cost of disposal.

Utility model content

Utility model content: being directed to the electronic wasting of resources of the existing technology, and utilization efficiency is not high, water separation capability is low etc. Problem, the utility model provide a kind of original position movable electric dehydration soil engineering bag on the spot, realize that silt sludge high efficiency synchronous is dehydrated decontamination Processing, the soil engineering bag of the utility model are combined the unit by organically combining electro reclamation, chemical remediation with soil engineering bag, Using the effects of electromigration, chemical passivation and soil engineering bag excellent performance and extensive use, especially movable electricity is de- with dosing one Bodyization combines, and efficiently utilizes electricity to take off the dehydration for taking off integrated apparatus realization silt sludge in situ with medicine and administers with decontamination, to realize The dehydration decontamination of silt sludge is synchronous in soil engineering bag administers, while the soilization for being conducive to subsequent soil engineering bag silt sludge utilizes.

Technical solution: to achieve the goals above, movable electric dehydration is native on the spot for a kind of original position such as described in the utility model Work bag, including cabinet and soil engineering bag, top can be lifted by being provided at the top of the cabinet, and bottom end, which is provided with, can open bottom；The soil Work bag surrounding is connected closely with cabinet, and the soil engineering bag upper end is connected with anode power grid, and lower end is connected with cathode power grid；It is described can Switch button and power supply device are provided at the top of lifting.

Wherein, described open is provided with collection water layer between bottom and cathode power grid.Bottom can be opened have with cathode power grid and catchment Layer, soil engineering bag bottom are connected to on cathode power grid, collect when soil engineering bag final step mentions Shi Yuke upwards and opens to be formed between bottom Water layer, all in soil engineering bag, water takes off into collection water layer mud.

The cathode power grid is set as honeycomb, is modified by mesoporous carbon-iron.It can be according to the actual situation between power grid Neatly disposition is carried out with actual demand and is utilized, and if puree amount height differs larger with positive and negative anodes battery plate spacing, can suitably be adjusted Whole battery plate spacing.Cathode power grid is set as honeycomb simultaneously, and material carries out mesoporous carbon-iron modification, using mesoporous carbon absorption with The redox of iron carries out a part of removal, while can also have a degree of buffering to the pH value of silt sludge.If Mud amount pollution level, water content etc. are excessive, when single electricity is de- and electromigration is unable to satisfy actual treatment requirement, can carry out chemical drugs Agent processing, such as prepare certain density curing agent, passivator and homemade environment-friendly material.Therefore the utility model can be with Accomplish the silt sludge reparation that maximal efficiency is realized while economizing on resources and dredging purpose, while cathode power grid not only acts as electricity Pole itself acts on, while can play the role of grid to the muddy water of entrance like an object is accomplished in the muddy water soil engineering bag filtration on top Multi-purpose function.
