Introduction to the use of sewage treatment

After sewage treatment, there are various uses, and the following are some common aspects:

Urban miscellaneous use

Green irrigation: can be used for irrigation water in urban parks, green belts on both sides of roads, golf courses, etc., which can effectively save water resources and avoid waste caused by using tap water for irrigation.

Road cleaning and flushing: As a water source for urban road sweepers and sprinklers, it flushes and reduces dust on the road surface, maintains the cleanliness and hygiene of urban roads, and reduces dust pollution.

Construction: During the construction process, it can be used for concrete mixing, curing, and dust reduction on the construction site, which helps to reduce construction costs and reduce dependence on fresh water resources.

Industrial reuse

Cooling water: Many industrial production processes require a large amount of cooling water, such as thermal power generation, steel, chemical and other industries. The treated sewage can be further treated and used as cooling circulating water, which can effectively save industrial water, improve the reuse rate of water resources, and reduce the production cost of enterprises.

Process water: In some industrial production processes that do not require particularly high water quality, such as papermaking, textile printing and dyeing, treated wastewater can be used as process water. After appropriate deep treatment, it can meet the production needs of these industries and reduce the consumption of high-quality water resources.

Landscape environment water use

Urban landscape water replenishment: It can be used as a water source for urban landscape lakes, artificial wetlands, fountains and other landscape water bodies, creating a beautiful urban landscape environment and increasing the beauty and ecology of the city.

River ecological water replenishment: used to supplement the water volume of urban rivers, maintain the ecological flow of rivers, improve river water quality and ecological environment, help restore the function of river ecosystems, and protect the habitats of aquatic organisms.

Supplement groundwater

By artificial recharge and other methods, the treated standard sewage is injected into the groundwater aquifer to supplement groundwater, alleviate the problem of groundwater overexploitation, maintain stable groundwater levels, and improve regional hydrogeological conditions. This is of great significance for preventing ground subsidence and protecting groundwater resources.

Drinking water source

In some water scarce areas, after strict deep treatment and disinfection processes, the treated sewage can be used as a supplement to drinking water sources. For example, membrane treatment technology, advanced oxidation technology, etc. are used to deeply purify sewage to meet drinking water quality standards, and then mixed with other water sources to be supplied as drinking water.

Agricultural irrigation

The treated wastewater can be used for irrigation in farmland, providing water and nutrients for crops. However, appropriate treatment and monitoring of sewage should be carried out based on the types of crops and soil conditions to ensure that pollutants in sewage do not pose a threat to soil, crops, and human health. This can save agricultural irrigation water and improve the efficiency of water resource utilization.
