Method.
Background technique
China falls behind nearly 20 years in terms of contaminated soil remediation technical research than developed country, recovery technique, equipment and rule
There is also larger gap, crucial repaired item wretched insufficiencies on for modelling.As environmental protection industry is greatly developed, environmental protection equipment is cured
Add and is taken seriously.On October 24th, 2017, the Ministry of Industry and Information Technology's publication is newest " to promote environmentally friendly equipment manufacture about quickening
The instruction of development ", it is indicated that guarantor's equipment manufacture innovation ability is not also strong at present, and product low side homogeneous competition is serious, first
The problems such as difficult into technical equipment application, still protrudes；It is proposed is carried out in an all-round way green manufacturing, and environmentally friendly equipment manufacture is promoted
It is horizontal；It is required that China will cultivate the environmental protection equipment manufacturing industry leading enterprise of 10 10,000,000,000 yuan of scales to the year two thousand twenty, the industry output value reaches
To 1,000,000,000,000 yuan；Optimize environmental protection equipment product structure, expand product and segment field, gradually exploitation is formed for different industries, tool
There are complete set, the tandem product of independent intellectual property right, for environmental improvement cost and operational efficiency, gives priority to a collection of intelligence
Type, energy-saving advanced high-efficiency environment friendly equipment；Soil pollution repaired item is classified as nine and gives priority to one of field.To sum up institute
It states, the characteristics of for soil pollution, breaks through the key technology of soil pollution repaired item, independent research green energy conservation type, intelligence
The advanced efficient soil pollution repaired item of change simultaneously forms corresponding intellectual property, for accelerating development advanced environmental protection industry, pushing away
There is very important meaning into manufacturing power construction.
Heavy metal pollution is China's soil pollution main problem.According to " national soil investigation bulletin ", China's soil pollution
For type based on inorganic type, exceeded digit of inorganic pollution accounts for the 82.8% of all exceeded points, major pollutants be cadmium,
Mercury, arsenic, copper, lead, chromium, zinc, 8 heavy metal species of nickel.Heavy-metal contaminated soil generallys use curing/stabilizing recovery technique, solidify/
The key of Stabilization Remediation Technology engineer application is the mixing of soil and repair materials, and domestic soil remediation equipment is equal at present

Tin ore, tungsten ore etc., mostly with As, Cd association relationship, soil is often the compound dirt of the heavy metals such as Pb, Zn, Cu, Cr and As, Cd
Dye.On the one hand, the applicable repair materials of different heavy metals immobilization/stabilisations are different, as Cd and As exists in reparation in soil
Antagonistic effect, stepwise reaction are conducive to the collaboration reparation of different heavy metals；On the other hand, different types of repair materials hybrid reactor
Putting together can react, and influence repairing effect, such as lime is mixed with aluminium chloride, magnesium chloride material, first can voluntarily generate
Indissoluble substance seriously reduces the repairing effect of repair materials, and conventional soil prosthetic appliance intelligence degree is low, Bu Nengfen
Step adds repair materials.
