We will jointly promote the utilization of sewage resources to drive the upgrading of the sewage treatment industry

(3) Gradually promote the construction of recycled water utilization management system to ensure the safe utilization of recycled water

Improve safety awareness and establish a risk prevention and control system. Reclaimed water utilization is a non-traditional water supply project, its premise is to ensure the ecological safety, health safety and process safety of reclaimed water utilization, and continue to improve the public acceptance. The risk prevention and control of recycled water utilization should adhere to the basic principle of "whole-process management and prevention first", comprehensively identify and evaluate the possible risks and their sources in all aspects from sewage collection, treatment and recycled water treatment, storage, transmission and distribution to recycled water utilization, and formulate risk prevention programs. Gradually establish the certification and evaluation system of recycled water plants, improve the risk prevention awareness, prevention ability and emergency management ability of recycled water production and water supply enterprises, and improve the safety and reliability of recycled water supply.

We will improve the standard system and raise the scientific level of risk management. Different from drinking water supply according to unified water quality, recycled water utilization follows the basic principle of "quality by use, quality by use, and pipe by use". China has promulgated water quality standards for different uses of recycled water, initially solving the problem of "quality by use", but the lack of "quality by use" and "use by use" standards, the lack of basis for the determination of recycled water utilization prices and safety supervision, it is difficult to achieve high quality and price, quality control. Therefore, it is necessary to accelerate the formulation of standards such as recycled water quality classification, utilization benefit evaluation, risk management and service supervision to support the safe and efficient utilization and large-scale utilization of recycled water.
