How to choose polyester waste gas treatment equipment correc

After decades of development, PET production technology and technical level have become mature, but what kind of waste gas treatment equipment is selected for PET production and the industrial waste water and waste gas treatment in the whole polyester production process is only in the initial stage. Timely and effective treatment of waste water and waste gas problems in the polyester production process can reduce the environmental impact of chemical production Pollution.
Polyester wastewater discharged into the water flow will do harm to the water ecological balance, cause a large area of death of aquatic organisms, and seriously cause irreparable damage to the biological chain. However, after the treatment of polyester wastewater and separation of pollutants, it will not only not cause harm to the ecological environment, but also provide a lot of nutrients for water supply organisms, which plays a role of turning waste into treasure. It can not only improve the surrounding environment of polyester chemical plant, but also reduce the production cost of the plant.
China's polyester production capacity has stepped into the first place in the world. With the gradual improvement of enterprise production process and facilities, the production capacity is also increasing. Up to now, wastewater treatment methods commonly used in domestic chemical plants include "composite biological aeration", "biological flotation" and activated carbon adsorption, which can be summarized into three categories in principle, namely biological treatment Adsorption and oxidation treatment. Research data shows that different treatment methods have different advantages and disadvantages. Biological flotation is very sensitive to the quality and flow of water flow. It is generally not used in chemical plants with large production, and the investment and operation cost of equipment also increase with the increase of production. Therefore, most manufacturers will adopt it according to their own production capacity and specific process of wastewater Use appropriate treatment.
