The environment of the city of Ordos in North China's Inner Mongolia autonomous region has been steadily improving due to the city's efforts.

Statistics show that in 2021, the number of days with "good" or "excellent" air quality in Ordos reached 313 – a rate of 85.8 percent.

The average concentration of PM2.5 was 22 micrograms per cubic meter, while the water quality compliance rate of central urban drinking water sources, the safe utilization rate of polluted land and the safe utilization rate of contaminated farmland were all 100 percent.

To achieve these goals, Ordos took significant measures to reduce air, water and land pollution.

In 2021, there were 62 new green mines at or above the autonomous region level, bringing the total number of such mines in the city to 233.

A total of 79 entities, or 95 percent of the total, in Ordos completed ultra-low emission transformation. The city's ferroalloy, coking, cement, and electrolytic aluminum industries had all met emissions requirements, and a total of 162 coal-fired boilers were eliminated.

In addition, a total of 6.80 billion yuan ($1.02 billion) was invested in the comprehensive management of the environment in Wuhai Lake and surrounding areas, and more than 1,000 renovation tasks were completed.

Ordos has also investigated and rectified sewage outfalls in the Yellow River Basin and completed a 1,117-square-kilometer drone aerial survey of the main stream and important tributaries of the Yellow River.

Furthermore, the city has been carrying out water environment treatment projects for tributaries of the Yellow River, including Ulan Mulun River, Shida Kongdui, Huangfuchuan, and Gushanchuan to maximize the utilization of water resources.

All 32 of the city's coal chemical enterprises achieved high-salt crystallization and salt separation, while 31 sewage treatment plants achieved stable and up-to-standard renovation work.

The city's 282 villages also improved their environments, building 33 domestic sewage treatment facilities in townships and rural areas and successfully applying to become national groundwater pollution prevention and control pilot areas.

Ordos also built seven slag fields for the chemical smelting industry, 17 slag fields for thermal power plants, 14 ash slag fields for industrial parks, and seven comprehensive treatment plants for natural gas pollutants.
