The utilization directions of unconventional water sources mainly include

The utilization directions of unconventional water sources in my country mainly include landscape environment water, industrial water, urban non-drinking water, agricultural water, forestry water, groundwater recharge water, etc.

Unconventional water sources are different from water resources in the traditional sense. They mainly include rainwater, recycled water, desalinated seawater, mine water, brackish water, etc. Their characteristic is that they can be used or recycled after treatment, and can replace conventional water resources to a certain extent. . Landscape environment water use can be divided into ornamental landscape environment water use, recreational landscape environment water use and wetland environment water use.

Industrial water can be divided into cooling water, washing water, boiler water, process water and product water according to its use; urban non-potable water includes water for toilet flushing, vehicle washing, urban greening, road cleaning, construction and other water; agricultural water and forestry water mainly Refers to agricultural and forestry irrigation water; groundwater recharge water can be used to recharge groundwater sources, prevent seawater intrusion, and prevent land subsidence, etc.

Unconventional water sources are an important supplement to conventional water sources and can effectively promote the conservation, protection and recycling of regional water resources. They are also important for alleviating water shortages, implementing energy conservation and emission reduction goals, promoting the development of circular economy, and improving regional water resource allocation efficiency and utilization benefits. It is of great significance to improve and protect water ecology and environment.

Versatile and an important supplement to conventional water resources:

Broadly defined unconventional water sources cover all other water sources other than conventional water sources (surface water, groundwater), including recycled water, rainwater collection, desalinated seawater, brackish water, mine water, etc. Unconventional water sources are difficult to develop and utilize under conventional conditions, but with the advancement of science and technology, they can be obtained through new technologies, processes, methods and management measures.

It has special water quantity, water quality characteristics and development and utilization methods, which can replace conventional water sources to a certain extent. Increasing the utilization of unconventional water sources is important in three aspects. First of all, it can effectively alleviate my country’s water shortage problem in the new era. Secondly, it can effectively reduce the pollution of my country’s water environment.

In addition, it can effectively improve the carrying capacity of water resources and support healthy economic and social development. The utilization of unconventional water sources has strong public welfare characteristics. Compared with conventional water resources, the construction and treatment costs of unconventional water sources are higher. In the early stages of industry development, strong government support is especially needed.
