How to select polyester waste gas treatment equipment correctly?

Through decades of development of PET production technology and technology level has become mature, but the selection of waste gas treatment equipment, industrial wastewater and waste gas treatment during the production of PET and the whole production process of polyester products are only in the initial stage, timely and effective treatment of waste water and waste gas in the production process of polyester can reduce the environmental form of chemical production. The resulting pollution.

Polyester wastewater discharged into the water will damage the water ecological balance, occur the phenomenon of large-scale death of aquatic organisms, and seriously cause irreparable damage to the biological chain.

However, polyester wastewater will not damage the ecological environment, but also provide a lot of nutrition for aquatic organisms. It can not only improve the environment around the polyester plant, but also reduce the production cost of the plant.

China's polyester production capacity has now entered the international forefront. The gradual improvement of enterprise production process and equipment has made the production capacity continuously added. Up to now, the waste water treatment methods widely used in domestic chemical plants include "compound biological aeration", "biological flotation" and activated carbon adsorption. In principle, they can be summarized into three categories, namely, biological treatment, biological flotation and activated carbon adsorption. The oxidation treatment was approved.

Research data show that different treatment methods have different advantages and disadvantages. Bioflotation treatment wastewater is very sensitive to the quality and flow rate of water flow. Chemical plants with larger output value generally do not use this treatment method. The investment and operation cost of equipment also progress with the progress of output value, so most of the producers will select according to their own production capacity and wastewater detailed process. Use appropriate treatment methods.
