Abstract
The invention provides a method for treating heavy-metal-polluted water through yeast. The method comprises the following steps: drying the waste yeast to obtain dry yeast powder; adding the dry yeast powder into a reaction chamber; introducing heavy-metal-polluted water into the reaction chamber; absorbing heavy metal through the yeast dry yeast powder; and leading the treated water outside. According to the method provided by the invention, polluted water can be treated by waste beer yeast, so that not only is the purpose of waste utilization achieved, but also the heavy metal pollution problem is solved by adopting the environment friendly method.
Description
Technical field
The present invention relates to the heavy metal-polluted water process field, and be particularly related to a kind of method of waste yeast thalline treatment of heavy metal polluted water body.
Background technology
Developing rapidly of modern industry produced a large amount of heavy metal-containing waste waters, and these waste water have constituted very big threat because of its non-degradable and easy in food chain enrichment in vivo to environment and human lives.Therefore, how to administer heavy metal wastewater thereby and to reclaim valuable metal be the outstanding problem that current environmental protection work faces.The method of handling heavy metal wastewater thereby at present mainly contains chemical precipitation, IX, electrochemical treatment, r-o-, membrane technique, distillation, electrodialysis etc.; These treatment processs have obtained good effect to a certain extent; But ubiquity secondary pollution; Particularly when the heavy metal concentration in the water lower (＜100mgL-1) time, not only clearance is lower, and working cost is higher.
Biological absorption more and more receives people's attention as a kind of emerging heavy metal removal technology.Biological absorption is exactly through the adsorption to heavy metal ion in the water of organism and verivate thereof, reaches the purpose of removal heavy metal.The biomaterial that can adsorb heavy metal and other pollutent is called biological adsorption agent; Mainly comprise bacterium, fungi, algae and agriculture and forestry organic waste material; Compare with traditional sorbent material, they have following principal character: (1) wide adaptability, can under different pH values, temperature and the course of processing, operate; (2) selectivity is high, can be from solution Adsorption of Heavy Metal Ions and do not receive the interference of alkalimetal ion; (3) the concentration of metal ions influence is little, at lower concentration (＜10mgL
-1) and high density (＞100mgL
-1) under the good metal adsorptive power is all arranged; (4) to the organism better tolerance, Organic pollutants (≤5000mgL
-1) do not influence the absorption of metals ion; (5) regenerative power is strong, step is simple, and regeneration back adsorptive power does not have obvious reduction.
Summary of the invention
The present invention proposes a kind of method of waste yeast thalline treatment of heavy metal polluted water body, can utilize waste beer yeast that polluted-water is handled, can either utilization of waste material, and can use the method for environmental protection to solve heavy metal pollution problem again.
In order to achieve the above object, the present invention proposes a kind of method of waste yeast thalline treatment of heavy metal polluted water body, comprises the following steps:
Waste yeast thalline drying treatment is obtained yeast dry powder thalline;
Said yeast dry powder thalline is added in the reaction cavity;
Said heavy metal-polluted water is fed in the said reaction cavity;
Said yeast dry powder thalline absorption heavy metal;
Water body after handling is flowed out.
Further, said waste yeast thalline is the remaining discarded cereuisiae fermentum in wine brewing back.
Further, the density of said yeast dry powder bacterium in reaction cavity is 40～60g/L.
Further, the pH value of said yeast dry powder bacterium in reaction cavity is 5～8.
Further, the reaction times of said yeast dry powder bacterium and heavy metal-polluted water is 60～120 minutes.
Further, the temperature of reaction of said yeast dry powder bacterium and heavy metal-polluted water is 10～25 degrees centigrade.
The method of the waste yeast thalline treatment of heavy metal polluted water body that the present invention proposes; Utilize the remaining discarded cereuisiae fermentum in wine brewing back to have the characteristics of adsorbing metal ions; Utilize waste beer yeast that polluted-water is handled, can either utilization of waste material, can use the method for environmental protection to solve heavy metal pollution problem again; The advantage that the present invention has that raw material is easy to get, technology is simple, be convenient to operate, cost is low is convenient to big area and is promoted.
