BỘ GIÁO DỤC VÀ ĐÀO TẠO TRƯỜNG ĐẠI HỌC NGUYỄN TẤT THÀNH

Thực vật cải tạo môi trường nước

Phytoremendiation

Phytoremendiation

Phyto Remendiation

(Thực vật) (Phục hồi)

Was born in 1991.

It is widely used to refer to the technology used to

remove organic pollutants (Plant protection products, high molecular weight…) and inorganic (Cu, Zn, Pb, Cd… even radioactive elements) out of the contaminated

enviroment (Land, Groundwater, Wastewater, Sludge…).

The mechanisms of phytoremendiation

Phytoremendiation

Phytoextraction (Tách chiết)

Phytovolatilisation

(Bay hơi)

Rhizophere

Bioremendiation

(Xử lí bằng vùng rễ)

(Cố định) Phytotransformation

(Chuyển dạng)

* Waste water treatment and nutrient recycling

* Turns solar energy into energy in living

organisms

* Destroy the germs

Treatment by algae

* It can be detrimental to humans because of

their rapid development and wide distribution

* However, use them to treat waste, make

division compost, food for humans and cattle

Treatment of wastewater

In large-scale aquatic plants

Some typical aquatic plants

Blyxa Blyxa aubertii

Treatment of polluted water in the lake

The task of aquatic plant

In processing systems

Body part Mission

Roots or trunks It is a clamshell for bacteria to grow

Filter and absorb solids

Body, leaf in the water or above

the water

Absorb sunlight thus preventing the

growth of algae Reduces the effect of wind on the

processing surface Reducing exchange between water and

the atmosphere Transfer the oxygen from the leaves to

the roots

Use sunlight

On-site treatment

Low cost, 10% to 20% compared to conventional Less secondary waste

No smell

The treated soil can continue to be used

Advantages

Limited biomass

Limited to shallow soil, folwing water and

groundwater

Bioaccumulation potential and toxicity of

decomposition products have not been determined Contaminants are likely to enter the food chain

through herbivorous plants

Contaminants can penetrate deeper into the

groundwater by the roots

Defect

Plant technology is a new technology

Prospect for cleaning metals in soil

The development of propagation and molecular biology is essential for this type of technology

The prospect of transgenic plant in cleaning

contaminated areas
