Description
Technical field
The present invention relates to alkaline land soil improving technology fields, and in particular to a kind of alkaline land soil mercury, cadmium ion removal
Agent and preparation method thereof.
Background technique
Recently as the fast development of social economy, heavy metal in soil content is continuously increased, heavy metal pollution of soil
Universal environmental problem is had become, is had been to be concerned by more and more people.China's soil pollution by heavy metal event in recent years is looked back, no
Wherein mainly based on the heavy metals such as mercury, cadmium, they shows concealment, hysteresis quality, accumulation property and difficult invertibity for hardly possible discovery,
Especially in alkaline land soil, these phenomenons are more obvious, bring serious threat to ecological environment and food safety, meanwhile,
It is also Soil Pollution Control difficult bank together with repair.Official's data is shown within 2014, the mercury contaminated arable land soil in the Wanshan Mountain
About 100,000 mu of earth area, it is related to 100,000 people of population or so, 0.207~255mg/kg of Mercury in Soil concentration, maximum superscale 572.3
Times.On on March 6th, 2016 to April 5, in order to evade supervision, intermittent malice steals row without appointing for Yichuan Zhong An Industrial Co., Ltd.
The sewage of where reason, cadmium concentration severely exceeds in outlet saliva, causes Yuan He and fairy maiden lake cadmium, thallium, arsenic exceeded, takes from fairy maiden lake
The Xinyu City third water factory of water, which fetches water, interrupts, and Some City stops supplying water.Therefore, heavy metal pollution of soil repairs the research of aspect
It is extremely urgent.
Heavy metal pollution of soil Treatment process mainly has phytoremediation, microorganism remediation, chemical remediation and peripheral doses etc.,
Wherein phytoremediation technology has the advantages that at low cost, environmentally protective, but required repair time is longer；The big portion of microorganism remediation
Divide and all degrade just for around heavy metal, does not account for the absorption for reducing crop, and the simple microorganism remediation period is long；
The advantages of chemical remediation is the pollutant that can be removed in soil, the disadvantage is that there may be secondary pollutions；The physics such as soil removal and replacement, soil moved in improve the original
Recovery technique remediation efficiency is high, but only pollutant with by first being transferred to second, rehabilitation cost is higher, and transfer process
Risk is larger.
Salt-soda soil due to its soil property particularity, phytoremediation and chemical remediation application difficulty it is bigger, physics
Rehabilitation cost and height, so main at present consider microorganism remediation, but because of the particularity of alkaline land soil character, the mistake of reparation
Improvement soil environment is also taken into account in journey, and various conditions required for fungus grown are provided.
Summary of the invention
The first technical problem to be solved by the present invention is: in view of the deficienciess of the prior art, providing a kind of saline and alkaline

2 second year index situation of table
3 third year of table index situation
It can be seen that the soil for not applying white-rot fungi, arbuscular mycorrhizal fungi and citric acid by table 1-3, in soil
Variation in mercury, cadmium content continuous 3 years is little, mercury, cadmium content are exceeded in soil, crop kernel (arm's length standard is mercury ion content:
0.02mg/Kg, cadmium ion content: 0.1mg/Kg)；The Mercury in Soil of white-rot fungi is not applied, cadmium ion content is lower effect not
Obviously, and it is relatively slower；The Mercury in Soil of arbuscular mycorrhizal fungi is not applied, cadmium ion content is lower, but mercury, cadmium in crop kernel
Content is still exceeded；Mercury in Soil, the cadmium ion treatment effect for applying white-rot fungi, arbuscular mycorrhizal fungi and citric acid simultaneously are aobvious
It writes, second year starts to basically reach soil and crop seed under the synergistic effect of white-rot fungi, arbuscular mycorrhizal fungi and citric acid
The national standard of mercury in grain, cadmium ion content, and mercury, the compound standard of cadmium ion content in crop material may be used as animal feeding
Material.
