The implementation of sewage treatment discharge standards will inevitably affect the level of operating costs for sewage treatment. It limits the level of sewage treatment costs for sewage treatment plants at the same time, but also to a certain extent, what level they can reach. Strictly implementing emission standards and adopting measures such as complete nitrification, chemical phosphorus removal, and external carbon sources have increased direct costs by 30% to 50%.

At present, the sewage treatment fee collection level in the eastern region, ranging from 0.9 yuan to 1.5 yuan per cubic meter, basically meets the strict compliance requirements, while the level responsible for the western region is low.

With the rapid growth of the national economy, China's fiscal revenue has become significant, and I believe it is fully capable of supporting the cost of water pollution prevention and control.
