Analysis of the Modes and Prospects for Promotion of Recirculating Water Use in Agricultural Irrigation

Recirculating water use in agricultural irrigation refers to the recycling and reuse of water resources that may be wasted or polluted during the agricultural irrigation process, through the adoption of advanced irrigation technologies and management methods, achieving the efficient use of water resources while reducing the pressure on the environment. This article will analyze the modes of recirculating water use in agricultural irrigation and discuss its prospects for promotion.

I. Modes of Recirculating Water Use in Agricultural Irrigation

Recirculating Water Irrigation System: The recirculating water irrigation system is an advanced irrigation method that achieves the recycling of water resources through the collection, treatment, and reuse of agricultural irrigation water. The recirculating water irrigation system includes water circulation and filtration systems, water treatment systems, and sprinkler irrigation systems, etc. During the irrigation process, the system can collect, filter, disinfect, and reuse water, thereby achieving the recycling of water resources. This method can reduce water resource waste, lower irrigation costs, and at the same time, alleviate the pressure of agricultural irrigation on the environment.

Agricultural wastewater recycling: Agricultural wastewater recycling refers to the collection and treatment of wastewater generated during agricultural irrigation, recycling and reusing it for agricultural irrigation. Agricultural wastewater mainly includes drainage after irrigation, cleaning water of irrigation equipment, and wastewater from animal husbandry and breeding. Agricultural wastewater recycling can not only improve the utilization rate of water resources but also reduce the impact of agricultural irrigation on the environment. For example, some places have established agricultural wastewater treatment stations, treated agricultural wastewater for irrigation, and realized the recycling of agricultural wastewater.

Circular agriculture irrigation model: The circular agriculture irrigation model is a comprehensive irrigation method that combines the construction and maintenance of circulating water irrigation systems with the reuse of agricultural wastewater, forming an intensive and sustainable agricultural irrigation model. In the circular agriculture irrigation model, agricultural irrigation water not only includes the water resources collected and treated by the circulating water irrigation system but also includes the water resources reused from agricultural wastewater. In this way, it can achieve efficient utilization of agricultural irrigation water, reduce the cost of agricultural irrigation, and at the same time reduce the pressure on the environment.

The prospect of promoting agricultural irrigation water recycling

The prospect of promoting agricultural irrigation water recycling is very broad. Firstly, with the increasing shortage of water resources and the enhancement of environmental awareness, the recycling of agricultural irrigation water has gradually received people's attention. The government and enterprises have also started to increase investment to promote the development of agricultural irrigation water recycling. Secondly, the continuous progress of agricultural irrigation water recycling technology also provides technical support for promotion. For example, the construction and maintenance costs of circulating water irrigation systems are gradually reduced, and the treated agricultural wastewater can be directly used for irrigation, which improves the feasibility of agricultural irrigation water recycling. Finally, the recycling of agricultural irrigation water can not only improve the utilization rate of water resources but also reduce the cost of agricultural irrigation, improve the economic benefits of agriculture, and therefore has been supported and recognized by the majority of farmers.

However, the promotion of agricultural irrigation water recycling also faces some challenges. For example, the construction and maintenance costs of circulating water irrigation systems and the reuse of agricultural wastewater are high, and more investment from the government and enterprises is needed. In addition, the promotion of agricultural irrigation water recycling also needs to solve the water quality problem of agricultural irrigation water to ensure the safety of irrigation water. Therefore, the government and enterprises need to increase investment, promote the research and development and application of agricultural irrigation water recycling technology, and solve the promotion problems of agricultural irrigation water recycling.

Agricultural irrigation water recycling is an important way to achieve efficient water resource utilization and reduce the environmental pressure of agricultural irrigation. By promoting the recycling of agricultural irrigation water, the utilization rate of water resources can be improved, the cost of agricultural irrigation can be reduced, and the pressure on the environment can be alleviated at the same time. Therefore, the prospect of promoting agricultural irrigation water recycling is very broad, and it is worthy of our continuous attention and promotion.
