Red wine is a traditional drink in the world, and a large amount of wastewater is generated during its production process. These wastewaters contain high concentrations of organic matter and nutrients such as nitrogen and phosphorus. If they are discharged directly into the environment without treatment, they will cause serious pollution to the surrounding water and soil. Therefore, the treatment of wastewater produced by liquor factories is a very important link.
1. Biological treatment method
Biological treatment method is currently the most widely used treatment method. Its principle is to use microorganisms to decompose organic matter into carbon dioxide and water, and convert nutrients such as nitrogen and phosphorus into substances such as proteins in microorganisms. Biological treatment method has the advantages of simple equipment, convenient operation, and good treatment effect, but it requires a certain amount of time and space for treatment.
2. Physical and chemical treatment method
Physical and chemical treatment method includes coagulation, precipitation, filtration, adsorption and other links. Among them, coagulation is to add coagulants to condense the suspended matter in the wastewater into larger particles, which is convenient for subsequent precipitation or filtration. Sedimentation is to precipitate the coagulated particles to the bottom, and filtration is to separate the particles through a filter or filter material. Adsorption is to use adsorbents to adsorb organic matter or heavy metals in wastewater to the surface of the adsorbent to achieve the purpose of removal. Physical and chemical treatment methods can quickly remove harmful substances such as suspended matter and heavy metals in wastewater, but their operation is complicated and the cost is high.
3. Membrane separation technology
Membrane separation technology uses membranes made of special materials to separate dissolved organic matter, ions, etc. in wastewater. This technology has the advantages of high efficiency, energy saving, and pollution-free, but requires high technology and equipment investment.
The above three methods can effectively treat liquor factory production wastewater, but different methods are suitable for different situations. In practical applications, it is necessary to choose according to factors such as the nature of the wastewater, discharge standards, and economic benefits.
