Problems solved by technology

[0003] Facing the serious situation of soil pollution, the speed of national legislation has been significantly accelerated. In addition to adding soil remediation to the latest "Environmental Protection Law", the Ministry of Environmental Protection has recently announced a new "Soil Environmental Quality Standard (Draft for Comment) ", the formulation and implementation of the "Soil Pollution Prevention and Control Action Plan" (referred to as "Soil Ten Measures")

Embodiment Construction

[0086] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0087] refer to figure 1 Shown, a kind of multiple treatment technology of heavy soil pollution, comprises following technical steps:

[0088] Step 1. Assess preset restoration goals, including:

[0089] 1. Confirm the type of land use;

[0090] The above confirmed land use type can refer to the opinions of land holders and land users, and strictly abide by local laws and regulations;

[0091] As an example, the type of land use is: one of cultivated land, fitness square, factory land, school construction land, residential area, office area, etc.;

[0092] 2. Confirm the acceptable level of risk;

[0093]As an example, the acceptable level of risk means that according to the national environmental protection standards, when the corresponding land is constructed, the land label conforms to the national use standards;

[0094] 3. Determine...

Abstract

The invention discloses a multi-treatment technique and treatment equipment for heavy pollution of soil. The multi-treatment technique includes steps of scientific evaluation of a preset restoration target, soil restoration engineering, and recheck and inspection. The step of scientific evaluation includes determining soil application type, acceptable risk level, the type of pollutants, restoration coverage and final restoration target value. The step of soil restoration engineering includes heavy metal pollution treatment, organic matter pollution treatment and inorganic matter pollution treatment. After qualification is proved through recheck and inspection, the whole process is completed. By the combined treatment technique, efficient treatment efficiency can be guaranteed, and requirements on natural conditions are reduced; experiments verify that transferability and perniciousness of the pollutants to the soil and surroundings thereof can be reduced remarkably; the equipment is simple in structure and unique in design, small technical innovation is made to existing equipment, a qualitative leap is achieved in soil treatment effect, and cost performance is very high.

Description

technical field [0001] The patent of the present invention relates to a technical field of soil pollution treatment, especially a multiple treatment technology for heavy soil pollution and its treatment equipment. This invention uses special technical means to solve the problem of multiple soil pollution more scientifically than traditional methods. And it is green and environment-friendly, the treatment price is low, the equipment is simple and easy to operate, and the treatment effect is good. Background technique [0002] With the development of industrialization and the rapid increase of urban population, industrial production and daily life will inevitably cause certain damage to the environment. According to the "National Soil Pollution Survey Bulletin" released in 2014, the overall situation of China's soil environment is not optimistic. The national soil pollution rate is 16.1%. While the soil environmental problems of industrial and mining wasteland are prominent, t...
