The protection and utilization of water resources in the Yangtze River basin should be based on the comprehensive planning of the river basin, and priority should be given to meeting the requirements of Xiangwan ().
a.Domestic water for urban and rural residents.
b.Industrial water.
c.Hunger and feast water for agriculture.
d.Ecological water use.
Correct Answer: a
-
Answer]: C According to the "Technical Specification for Water Supply and Fire Hydrant System" GB50974-2014
The design dry water flow guarantee rate of natural water sources such as rivers, rivers, lakes, seas, and reservoirs should be determined according to the comprehensive factors such as the scale of urban and rural Changdong, the importance of industrial projects, fire hazard and economic rationality, and should be 90% 97%. However, the design dry water flow guarantee rate of outdoor fire water supply water sources in villages and towns can be appropriately reduced according to the local water source conditions.

Hello, I will discuss the methods of pollution treatment in the Yellow River Basin in combination with water pollution control engineering, including: 1Strengthen the supervision of industrial emissions, require enterprises to strictly control the discharge of pollutants in the production process, and adopt effective purification technologies, such as activated sludge method, aerobic denitrification, etc.
2.The establishment of domestic sewage treatment facilities requires the establishment of sewage treatment plants in urban and rural areas to effectively treat domestic sewage and reduce pollution to water bodies. 3.
Carry out river control projects, dredging rivers in the Yellow River Basin, and build river control projects to improve the water flow environment and reduce water pollution.
Combined with water pollution control engineering, the methods of pollution treatment in the Yellow River Basin were discussed.

2.The establishment of domestic sewage treatment facilities requires the establishment of sewage leakage treatment plants in urban and rural areas to effectively treat domestic sewage and reduce pollution to water bodies. 3.
Carry out river control projects, dredging the rivers in the Yellow River Basin, and build river control projects to improve the water flow environment and reduce water pollution.
Pollution control engineering refers to the engineering technology that reduces or eliminates water pollution by taking a variety of technical means to protect water resources and ensure human health and ecological balance through the treatment of water quality pollution sources. In the Yellow River Basin, water pollution is mainly caused by industrial discharges and the discharge of domestic sewage.
