Water resources pollution and its control

⒒ Develop new water sources

China's industrial, agricultural and domestic water saving potential is not small, we need to do a good job of water saving, reduce waste, to reduce the unit of GDP water consumption. The implementation of the South-to-North Water diversion project plays an important role in alleviating the severe water shortage in Shandong and North China. The construction of reservoirs, exploitation of groundwater and purification of seawater can alleviate the increasing pressure of water use, but the impact on the ecological environment and social environment should be fully considered when the construction of reservoirs and exploitation of groundwater.

⒓ We will strengthen planning and management of water resources

Water resources planning is the main component of regional planning, urban planning, industrial and agricultural development planning, and should be carried out simultaneously with other planning.

Rational development must also be based on the supply and demand of water, the implementation of a quota of water, and the unified development and utilization of surface water, groundwater and sewage resources, to prevent the depletion of surface water sources and the decline of groundwater levels, and to effectively achieve reasonable development, comprehensive utilization, active protection and scientific management.

Use the market mechanism and economic leverage to promote the conservation of water resources, and promote the management of sewage and its resources. In order to effectively control water pollution, the management should gradually transition from concentration management to total control management. Its main measures are:

(1) Strengthen the monitoring of water quality;

(2) The three industrial wastes should be discharged after treatment;

(3) Rational use of pesticides and fertilizers;

(4) It is forbidden to use a large amount of phosphorus-containing laundry detergent;

(5) Strengthen soil and water protection and plant trees.
