List of technical support units in the 2022 National Advanced Pollution Prevention and Control Technology Catalogue (Water Pollution Prevention and Control Field).

On December 29, the General Office of the Ministry of Ecology and Environment issued the Notice on Printing and Distributing the > of the 2022 < National Advanced Pollution Prevention and Control Technology Catalogue (Water Pollution Prevention and Control Field) (Huanban Ke Cai Han [2022] No.
500) (hereinafter referred to as the "Notice"
).

The National Catalogue of Advanced Pollution Prevention and Control Technologies (hereinafter referred to as the "Catalogue") in the Notice has a total of 38 technologies, including 21 demonstration technologies and 17 promotion technologies
.
The selected technology is obviously advanced, which is well in line with the current technical needs of water pollution prevention and control, and presents the following characteristics: (1) It reflects the changes in the
technical needs of water pollution prevention and control in recent years.
Compared with the 2019 catalogue, the proportion of water ecological restoration technology has increased significantly, accounting for 24%; The proportion of domestic sewage treatment technology has decreased, and the proportion of industrial wastewater treatment projects is basically stable
.
(2) The synergy characteristics of pollution reduction and carbon reduction are remarkable
.
On the basis of achieving pollution control, the characteristics of low energy consumption, drug saving, land saving, resource utilization and intelligence are remarkable, providing technical support
for the green and low-carbon development of water pollution control itself.
(3) New technologies to solve pain problems emerge.

The emergence of new technologies for the key needs of ecological environment management, such as aquaculture tailwater, acid wastewater, coal mine water inrush, and non-point source pollution, can provide a technical path
for solving some current pain points in ecological environment governance.
(4) A number of technologies in the hot field of research and development were selected
.
The integration and improvement of activated sludge process of domestic sewage treatment is more diversified, and technologies in recent years such as deep denitrification, intelligent operation and maintenance and control of sites, refractory industrial wastewater treatment and recycling, low-energy enhanced constructed wetlands, and water ecological restoration integration have been selected
.
(5) Specialization, special technology, equipment, materials, and pharmaceuticals are more diverse
.
New materials, fungi and equipment to improve quality and efficiency continue to appear, and the characteristics of specialization, refinement, specialization and novelty are remarkable
.
In order to enable relevant parties to better understand the technologies selected for the catalogue, the Petrochemical Federation compiled the 2022 National Advanced Pollution Prevention and Control Technology Catalogue (Water Pollution Prevention and Control Field) technical support list for reference and use
.
