Embodiment 1

[0044] Such as figure 1 Shown is a system for remediating soil by using rivers, remediating soil polluted by organic matter, including high-level water channel 1, distribution channel 2, repairing inclined bed 3, filter wall 4, filtrate treatment channel 5, wetland plant channel 6, water pumps, water pipes and Riverbed7.

[0045] The elevated water channel 1 is located at the uppermost part of the river bank and is arranged parallel to the river channel. The canal body of the high-level water channel 1 is made of concrete and environmentally friendly bricks, and there is a cover plate on it. The bottom of the high-level water channel 1 is provided with a slope inclined to the center of the river to reduce soil deposition. The lower end of the slope is provided with drainage outlets every three meters. A water level adjustment plate is placed on the mouth; further, a number of water inlets are provided on the upper part of the high-level water channel 1 to receive the river wa...

Embodiment 2

[0067] A system for repairing soil by using rivers to repair soil compounded with organic matter and heavy metals. The difference from Example 1 is that the filtrate treatment channel 5 is also provided with an adsorption hanging basket, and the hanging basket is filled with adsorbents. On the shell of the hanging basket There are holes. The adsorbent is activated carbon.

[0068] The method of soil remediation using the above-mentioned system of using rivers to remediate soil is as follows:

[0069] ① Use water pumps and water pipes to pump the water from the river bed 7 into the high-level canal 1, and the water from the high-level canal 1 enters the distribution canal 2 through the outlet. After the water enters the water distribution channel 2, the liquid medicine adding distributor adds ammonia water to increase soil fertility, and adds soil chelating agent ethylenediaminetetraacetic acid.

[0070] ②The water in the distribution channel 2 enters the repaired slanted bed...

Abstract

The invention relates to a system and a method for repairing soil by using a river, belonging to the technical field of soil repair. The system includes elevated water channels, distribution channels, rehabilitated slanted beds, filter walls, filtrate treatment channels, wetland plant channels, water pumps, water pipes and river beds. The invention transforms the beach and the river bed of the river into a device for repairing the soil, which has the advantages of simple construction, low cost, convenient management and beautification of the environment. Using polluted soil, coal gangue, and fly ash as raw materials, the sintering process is used to prepare environmentally friendly bricks. Toxic and harmful substances are solidified in the solidified body during the sintering process. After sintering and solidification, the heavy metal leaching rate is far lower than the national standard; Therefore, the sintering resource utilization of polluted soil, coal gangue and fly ash can not only solve the environmental hazards of polluted soil, coal gangue and fly ash, but also make full use of resources and turn waste into treasure.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a system and method for remediating soil by using rivers. Background technique [0002] In recent years, the problem of soil pollution has become increasingly serious. The heavy metals and organic matter in the soil are transformed between various forms in the environment, which has an impact and harm on organisms and humans. Countries around the world have begun to realize the seriousness of soil pollution, and have carried out research on the mechanism and technology related to soil remediation. [0003] The methods of soil pollution control mainly include physical method, chemical method, ecological restoration method and electrodynamic method. Each method has advantages and strengths, but also has shortcomings and defects. Electric restoration technology has the advantages of little impact on the site environment, energy saving, economical feasibility, and good trea...
