Description
Technical field
The invention belongs to fertilizer and soil conditioner preparing technical field, is related to one kind and prepares soil tune using weathered phosphoric ore
The process of agent is managed, is produced particularly under conditions of activator is added with pure Physical Processing technology by raw material of weathered phosphoric ore
The new process of soil conditioner, there is the effect of regulation soil ph, passivation heavy metal-polluted soil.
Background technology
China's phosphate rock resource is mainly distributed on Yunnan-Guizhou Chuan Xiang E Wu provinces, and southwest phosphorus ore weathering is universal, according to ore deposit at 105
Estimate that for China's weathered phosphoric ore stock number up to 14.90 hundred million tons, potential resources is 40.77 hundred million tons in area.Weathered phosphoric ore containing sludge compared with
It is more, sort that difficulty is big, and the efficiency of separation is low, not only beneficiation cost is high, and mine tailing is accumulated and brings pollution to producer and surrounding environment
With potential safety hazard.But weathered phosphoric ore relative activity itself is higher, the molten rate of Chinese holly is high, containing the elements such as active phosphorus, calcium, magnesium, silicon, tool
There is the potential effect for directly applying improved soil.
According to the annual report of National Geology investigation bureau of Ministry of Land and Resources 2015, China has 21.6% arable land acidifying serious.Weather ring
Border, acid rain depositions, chemical fertilizer application etc. are the principal elements for promoting arable land to be acidified.Acidifying not only reduces farmland quality, increases simultaneously
Add heavy metal-polluted soil active, grain security and groundwater environment are formed and threatened.
Heavy metal pollution of soil refers to that due to mankind's activity content of the minor metallic element in soil in soil exceedes
Background value, too high levels caused by excess deposition, and the phenomenon for causing eco-environmental quality to deteriorate.The 13.86 hundred million of investigation
In mu arable land, the site of heavy metals exceeding standard reaches 8.2%, wherein in-serious pollution or exceeded site account for 2.5%, area coverage
34880000 mu.Pollute exceeded area and be mainly distributed on Xiang Ewangan areas, Min Yueqiong areas and Southwest Region.
The present invention selects weathered phosphoric ore, dolomite, oyster shell whiting, lime stone, zeolite, slag etc. through physically activated, and with having
Machine thing proportions, and acidic soil conditioner is made.The conditioner can improve soil pH value, reduce heavy metal-polluted soil activity,
And soil available phosphorus and the active calcium ion content are improved, there is regulation soil ph, culture fertility, safeguard soil and Environmental Health etc.
