Most of our current generation has experienced the ups and downs of social development. Witnessing the gradual prosperity of our country, but we are also a generation witnessing the deterioration of the environment, watching many green mountains and rivers disappear. Fortunately, we have regained consciousness and started to increase rewards and punishments for environmental protection and damage to the environment. Similarly, the facilities used in sewage treatment are more strictly required.

We know that in previous sewage treatment systems, guardrails and aisle grilles were often made of steel, but due to long-term contact with sewage, they were quickly rusted and corroded by sewage. Also, the use of time can present irreversible twists and turns. In recent years, fiberglass grilles have emerged, which have strong corrosion resistance. So, in the sewage treatment system, it will not be corroded by sewage, nor will rust occur. Meanwhile, the fiberglass grating will not undergo irreversible twists and turns. And the quality of fiberglass is lighter, the quality of this raw material's grille is only about 1/4 of the original steel grille, greatly reducing the cost of the sewage treatment system.

The development of the economy is certainly important, but it cannot be valued for eliminating subsequent development. In this case, the current development cannot be continuous. So, we need to do a good job in protecting various environments. In sewage treatment, it is necessary to carefully select various environmentally friendly materials.
