Abstract
The invention discloses a kind of bio-feritlizer of reduction Cd pollutions, including following main component：Composite bacteria agent, urea, potassium dihydrogen phosphate, activated carbon, vermiculite and humic acid.The bio-feritlizer of reduction Cd prepared by present invention pollution, pass through the suction-operated of the mutual synergy of composite bacteria agent and the activated carbon and vermiculite of addition；Reduction for Cd reaches more than 85%；And with multiple efficacies such as improved soil structures.
Description
Technical field
The present invention relates to technical field of soil remediation, more particularly to a kind of bio-feritlizer of reduction Cd pollutions.
Background technology
It is heavy metal-polluted to have a finger in every pie the environmental pollution as caused by heavy metal or its compound.Mainly by mining, waste gas discharge, sewage
Irrigate and using caused by the human factors such as heavy metals exceeding standard product.
Cause the content of beary metal in environment to increase because of mankind's activity, beyond normal range (NR), be directly detrimental to health, and
Environmental quality is caused to deteriorate.At the beginning of 4 months 2011, first " the 12 " ad hoc planning of China ---《Heavy metal pollution integrated control
" 12 " are planned》Obtain State Council formally to give an written reply, control program makes every effort to control 5 heavy metal species.
Soil remediation is the technical measures for making to recover by contaminated soil normal function.It is existing in soil remediation industry
Soil restoring technology reach kind more than 100, common technology also has kind more than ten, is broadly divided into physics, chemistry and biological three kinds of sides
Method.Since the 1980s, in the world it is many country particularly developed countries formulate and carried out contaminated soil administer with
Rehabilitation plan, therefore also form an emerging soil remediation industry.
" high pollution exceeding standard rate " " TERA-SCALE scale market " " complicated system engineering " " emerging industry of the early stage of development ", in
It is first " international soil year " that state's Soil Pollution Control is just stepping into the United Nations close to these labels.
According to issue in 2014《National Soil Pollution Investigation publication》, Chinese soil environmental aspect do not allow totally to find pleasure in
To see, national soil pollution exceeding standard rate is up to 16.1%, on industry and mining discarded ground while soil environment outstanding problem, arable soil ring
Border quality more causes anxiety.In face of the severe situation of soil pollution, national legislation speed is substantially accelerated.Chinese Ministry of Environmental Protection is except new《Ring
Border Protection Code》In add outside the content of soil remediation, disclose again a few days ago new《Standard of soil environment quality（Consult on
Original text）》,《Soil Pollution Control action plan》（Referred to as " ten, soil "）Formulate and implement and also brought into schedule.Soil is dirty on a large scale
The exceeded promotion plus national legislation is contaminated, it is estimated in the industry to expedite the emergence of TERA-SCALE soil remediation market.But multidigit expert but represents,
Though cake is big but can not be unrealistically optimistic, the multiple barrier such as technology, fund, business model is limited by, soil remediation industry is want short
Done in time big and unrealistic.
The invention provides a kind of bio-feritlizer for reducing Cd pollution in soils.
The content of the invention
In order to solve the above technical problems, the present invention provides a kind of bio-feritlizer for reducing Cd pollution in soils.
A kind of bio-feritlizer of reduction Cd pollutions, including following main component：Composite bacteria agent, urea, potassium dihydrogen phosphate, work
Property charcoal, vermiculite and humic acid.
Preferably, bacillus laterosporus, Clostridium baratii microbial inoculum and arbuscular mycorrhiza microbial inoculum are included in described composite bacteria agent.
Preferably, the bio-feritlizer of described reduction Cd pollutions, the composition of following percentage by weight is included：
Urea 8-15%
Potassium dihydrogen phosphate 5-10%
Activated carbon 2-8%
Vermiculite 1-5%
