According to the Yellow River Protection Law of the People's Republic of China, the state implements a mandatory water quota management system in the Yellow River Basin and formulates the Yellow River Mandatory water quotas for high water-consuming industries and service industries in the Yellow River Basin. The national standard for mandatory water quotas is used to measure the water conservation efforts of relevant industries in the Yellow River Basin. It is an important standard for water level, an important means to implement the rigid water resource constraint system and the mandatory water quota management system in the Yellow River Basin, and also an important It is an important technical basis for the country to implement the water withdrawal permit system, implement planned water use management, and carry out water resources demonstration and water conservation evaluation. GB 45669 "Industrial Water Quota in the Yellow River Basin" specifies the calculation method based on the water use characteristics of different high water-consuming industrial sectors in the Yellow River Basin. The law stipulates mandatory water quotas and makes management requirements, and is intended to consist of the following 14 parts.

1.Thermal power generation. The purpose is to clarify the calculation method, index value and Management requirements.

2.Coal preparation. The purpose is to clarify the calculation method, index value and management of the mandatory water quota for coal preparation in the Yellow River Basin Require.

3.Coal-to-olefins. The purpose is to clarify the calculation method, index value and Management requirements.

4.Cement. The purpose is to clarify the calculation method, index value and management of the mandatory water quota for cement in the Yellow River Basin Require.

5.Iron and steel. The purpose is to clarify the calculation method, index value and management of the mandatory water quota for iron and steel in the Yellow River Basin Require.

6.Petroleum refining. The purpose is to clarify the calculation method, index value and Management requirements.

7.Coal-to-methanol. The purpose is to clarify the calculation method, index value and Management requirements.
