"14th Five-Year Plan" urban sewage treatment and resource utilization Development planning

About the combined overflow sewage rapid purification facilities. Checking and repairing the district pipe network

Under the premise of reconstruction, the construction of rapid purification facilities for combined overflow sewage is implemented with high efficiency

Remove sedimentary particles and floating matter, effectively reduce the total amount of urban water pollutants, promote

Long-term maintenance of water environmental quality.

(3) Strengthen the construction of recycling facilities and promote the utilization of sewage resources

1. Construction tasks. Combined with existing sewage treatment facilities upgrading and capacity expansion, system

Planning urban sewage recycling facilities, reasonable determination of recycled water utilization direction, promote real

Now divided quality, sub-object water supply, excellent water use. Downstream of the key sewage outlet, the river into the lake

The mouth and branch flow into the main stream, and implement the regional recycled water recycling project according to local conditions. Lack of

The new urban area of the water city should plan the layout of the reclaimed water pipe network in advance and carry out the construction in an orderly manner. Ehoang

River basin prefecture-level and above cities as the focus, in the Beijing-Tianjin-Hebei, Yangtze River economic belt, the Yellow River flow

Construction sewage in the region, along the South-to-North Water Diversion Project, in the arid areas of northwest China and in the coastal areas lacking water

Demonstration cities for resource utilization, planning and construction of supporting infrastructure, and realizing the scale of reclaimed water

Utilization. Construction of resource and energy benchmark reclaimed water plant. Encourage the extraction of nitrogen and phosphorus from sewage

Matter. During the "14th Five-Year Plan" period, the capacity of new construction, reconstruction and expansion of recycled water production is not less than

15 million cubic meters per day.

2. Technical requirements. Priority should be given to converting standard discharge water into utilizable water in water-scarce areas

The water resources of the nearest natural water body. Promote the use of reclaimed water for construction in resource-based water shortage areas

While using industrial water and municipal water for miscellaneous purposes, encourage the use of reclaimed water for ecological replenishment of rivers, lakes and wetlands

Water. In areas where conditions exist, local water resources are utilized, water environment is improved, and water ecology is improved

Demand, according to local conditions through the construction of wetlands, deep purification projects and other measures to optimize the town

The effluent quality of sewage treatment plants will improve the resource utilization level of urban sewage. Propulsion industry

Production, landscaping, road cleaning, vehicle washing, building construction and other fields are given priority

Use reclaimed water. Encourage industrial parks to cooperate with municipal reclaimed water production and operation units to promote

Point to point water supply.
