Does the utilization direction of unconventional water sources in China not include?

The utilization direction of unconventional water sources in China does not include sewage utilization.

Unconventional water sources are different from traditional water resources (surface water and groundwater), mainly including rainwater, reclaimed water, desalinated seawater, mine water and brackish water. Their characteristics are that they can be used or recycled after treatment, and can replace conventional water resources to some extent.

The utilization direction of unconventional water sources in China mainly includes landscape water, industrial water, urban non-drinking water, agricultural water, forestry water and groundwater recharge water. Among them, landscape water can be divided into ornamental landscape water, recreational landscape water and wetland water according to their uses.

Industrial water can be divided into cooling water, washing water, boiler water, process water and product water according to use; Urban non-drinking water includes toilet flushing, car washing, urban greening, road cleaning and construction water; Agricultural water and forestry water mainly refer to agricultural and forestry irrigation water; Groundwater recharge water can be used to supplement groundwater sources, prevent seawater intrusion and prevent land subsidence.

Unconventional water around us

1, seawater utilization.

2. Reclaimed water utilization. The average treatment rate of urban sewage in China is 70%, that of cities above the provincial capital is 80%, that of prefecture-level cities is 60%, that of county-level cities is 50%, and that of county towns is 30%. The utilization rate of reclaimed water in water-deficient cities in the north reaches 20%, and that in water-deficient cities in the south reaches 5% ~ 10%.

3. Utilization of mine water. The annual benefit of mine water consumption reaches 3.6 billion cubic meters.

4. Rainwater and flood utilization.
