In the process of development, airmen firmly establish the concept of "protecting the environment, building an image, saving energy, reducing emissions and increasing benefits", deeply implement the scientific outlook on development, actively promote energy conservation and emission reduction, and strive to carry out cleaner production. At present, many enterprises have successfully passed the cleaner production audit and acceptance, and the green cleaner production system has been basically established; Each enterprise gradually adjusts and optimizes its structure, continuously carries out technological transformation, updates production technology and equipment, and deeply carries out benchmarking and tapping potential; We have done a good job in the treatment of "three wastes" to ensure that the "three wastes" are discharged up to the standard, and successively completed the sewage treatment project, the smoke treatment transformation of finalizing machine and the thermal power desulfurization transformation project; Improve the comprehensive utilization of resources, adhere to the reuse of boiler waste heat and clean water, waste heat of setting machine waste gas, mercerization light alkali recovery, extraction of terephthalic acid from alkali reduction waste water, recovery and utilization of fly ash, etc.
