Description
Technical field
The invention belongs to attapulgite material technical field, relate to a kind of soil remediation adsorption net and restorative procedure thereof.
Background technology
Soil pollution has pollutant poor mobility, holdup time length, feature such as irreversible in soil, causes soil
Fertility declines, and crop yield and quality decline, and can be by runoff and leaching polluted underground water and surface water.
Adsorption filtration is the important technology during current soil deep purifying processes.The most conventional adsorbing material is active
Charcoal, activated alumina and ion exchange resin etc., though they can adsorb various pollutant effectively, but due to its relatively low absorption
Capacity, slower adsorption rate and poor mechanical stability etc. so that it is extensively application is restricted.
Combine exchange fiber and attapulgite material at present and carry out the technology of repair process soil, the most not
Can meet, in order to meet existing situation, soil remediation be needed further exist for, a kind of scheme of existing offer.
Summary of the invention
It is an object of the invention to provide a kind of soil remediation adsorption net and restorative procedure thereof.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of soil remediation adsorption net, including web plate, this web plate is compressing, for wavy shape by adsorbing material；
Described web plate thickness is 2-5mm, and on its surface the uniform bar shaped worry hole that has, and bar shaped worry hole is formed with the wave flanging of web plate
The inclination angle of 10-15 degree；The weight ratio that described adsorbing material is pressed 2-4:1-1.5 by ion-exchange fibre adds attapulgite powder body
Prepare.
Described ion-exchange fibre preparation method is: be sequentially added in a certain amount of vinal ethylene glycol with
Ethylenediamine, back flow reaction under stirring, obtain intermediate product；After intermediate product washes with water, add aminopyridine and chloroethene
Alkane mixed solution, reacts under stirring at normal temperature, successively by water, hydrochloric acid, water wash products extremely neutrality after terminating, obtains ion exchange fibre
Dimension.
Described web plate is the bulk of 1.5m*1.5m, or is the strip of 2m*1m, or is the circle of 1.5-2m for diameter.
The restorative procedure of a kind of soil remediation adsorption net, the method degree of depth that includes nuzzling adsorption net is 15-25cm soil
Middle 15-30 days.
Beneficial effects of the present invention: the present invention prepares adsorption net by attapulgite powder body and exchange fiber, is applied to soil
The improvement reparation polluted, restorative procedure is simple, quick, is suitable for industrialized production, and can forever remove soil by absorption, exchange
In harmful substance, reach the purpose that rehabilitating soil pollutes, reduce the leaching concentration of harmful substance in soil and heavy metal at soil
Animal migration in earth and the degree of murder by poisoning.
Accompanying drawing explanation
For the ease of it will be appreciated by those skilled in the art that the present invention is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is one soil remediation adsorption net structural representation of the present invention；
Fig. 2 is enlarged diagram at B in Fig. 1.
